This is not a bug, but merely a result of DNS propagation. Our tool queries the blocklist provider's DNS servers and returns the results. Sometimes a list will update DNS before or after their Web interface, which can provide different results.

Our tool acts in the same manner that a receiving mail server would, so if you see results on our tool, your mail delivery might be being impacted.

In order to minimize false positives due to connection problems by our monitoring services, we ask that you please whitelist these IP ranges on your firewall or network security systems:

• 44.194.168.193
• 52.55.244.91
• 18.205.72.90
• 18.209.86.113

Backscatterer lists based on Misdirected Bounces or Misdirected Autoresponders or Sender Callouts. They do not offer delistings and will only remove you after they do not see this traffic for 30 days.

Keep in mind that this list is a "best practices" list and very few people block email based off this list. Many large mail systems, such as Windows Live Mail, Gmail, Yahoo, etc., end up on this list. If you are having delivery issues, there might be something else that needs to be addressed.

In short, they want you to not send bouncebacks for non-existent email accounts. Any vacation auto-responders or auto-replies should not send more than once in a 24-hour period, and your system should not use the VRFY command to check if an address is valid (few systems do by default anymore).

You can opt out of being alerted to a status change by going to your notification policy. You can find your notification policy by clicking on "Monitor", then "Notifications", then the appropriate policy (usually default).

You will find the "Filters" section at the bottom. You can choose to opt out of receiving alerts about any specific status change you wish by using the drop-down box.

Our anti-abuse system has banned your IP address for too many lookups. Please make sure that you are not using an automated system to perform lookups on our tools. If you are running an automated system to perform lookups, we suggest using our API.

More information about our API can be found here.

Once you are in Settings, do the following:

1. Click on Account.
2. Input the email address you would like to add.
3. Choose if you want the new user to have User or Editor rights.
4. Click on Add User.

All invoices are emailed with the subject "MxToolBox Invoice#" to the email address on file when we process the credit card on file. Please check your Spam/Junk Folder and ensure that our email address is on your Whitelist/Approved Senders.

You can access past invoices from the Billing tab.

Or, you can click on your email address in the top right corner, then click on Billing.

1. Under the Invoices section, click on View to see your previous invoices.


2. If needed, click on Update Card to update your credit card information.

If you are receiving alerts for your Mailflow monitor and you are still able to send and receive email, chances are we did not receive a test message back to our system.

Click on the monitor and let it populate in the right window of the page. Under the graph you will see Outages | History | Pings | Edit > Click on Pings.

There are two (2) different results under the Pings table.

1. A message with a Green Check is a successful message returned to us. You can click on the details link and it will provide you the full headers and more information about the test message.
2. A message with a Red X on it is a failed message. If you click on Error, this will show you the test message's subject.

If the message is failing:

• Use the message subject to check that it is not being filtering by an inbound appliance or spam software.
• Use the message subject to check your outbound SMTP logs to see if the message is leaving your gateway.

Depending on the type of plan you have, in some cases, you might see a line item for "Adjustment for services added...". This is because we bill in advance for services for the upcoming billing period (e.g., month, quarter) and in arrears for services added during the previous period (e.g., month, quarter). This adjustment is the difference between what you paid the previous month/quarter and the services actually used.

This will only occur if you added new monitors to your account since your last billing period.

Blocklists affect your email reputation and can impair the delivery of your messages. While there are many additional factors in email delivery, knowing if your IPs/domains are blocklisted is a critical aspect of email delivery.

Blocklists are private entities that can add or remove IPs/domains as they see fit. It can often be frustrating when trying to request removal, especially when the lists simply do not respond. Be aware that when requesting removal, you need to follow all of the instructions on the specific blocklist’s site and that you explain what actions you have taken to ensure your system is safe and secure. We recommend that you address the following aspects of your request for removal:

1. Ensure you have included all of the information requested. If there is a form to fill out, make sure the information is thorough and accurate. If an email or general input box is used, be sure to read through any text on the page. Often, lists will request something specific and if it is not included, your request will be ignored.
2. You must explain the actions you have taken to check your system. This should include actions such as virus scans, reviewing email logs, and using the Mxtoolbox SMTP Tool to check for an open relay. The more information you include about what you did to resolve the problem or check to ensure that your system is not compromised, the more likely your request will be successful.
3. Be nice. MxToolbox has worked with many of these lists, as well as users who have tried various tactics with the people running them, and we have found that rude, aggressive, or threatening messages never work. You are either messaging an automated system that will not care or, in some cases, a person who will likely disregard your request due to hostile language.
4. Be proactive about improving your email reputation and message delivery. If you repeat the same habits that caused your domain to be blocklisted, you run the risk of being listed again. Implementing DMARC is a major step toward blocklist avoidance. MxToolbox's Delivery Center also helps you maintain a healthy domain, so check to see how it can improve your business email.

Although MxToolbox does NOT blocklist IPs/domains, we report on blocklistings. For tips on being delisted from specific blocklists, click here: Blocklist Knowledge Base.

Our subscribers have direct access to the MxToolbox Support team for any delisting concerns. And our convenient blocklist alerts provide links to the necessary removal steps. We have many years of experience with blocklists and are eager to help you.

There could be a brief delay after DMARC setup is complete, so your email data might not be instantly available. The most common reasons why no data is populating the dashboard once you properly set up an MxToolbox DMARC Record include:

1. Incorrect Emailing Domain: This is fairly common. You added a domain and DMARC record, but you are sending from a different domain. | Solution: Confirm the domain that you are sending emails from. This is more common when you add a subdomain but send mail from the primary domain and vice versa.
2. DNS Propagation: This is not very common, but it does happen sometimes. | Solution: Wait 24 to 72 hours after confirming that the proper record was added and not changed.
3. After set up, you removed your DMARC record: Again, this is not very common, but it does occur. | Solution: Confirm that the proper DMARC record that MxToolbox requires is configured in the domain's DNS.
4. You are sending to recipient systems that do not report DMARC data. | Solution: There is no resolution for this, only an explanation. (i.e., If you believe you are only sending to Office 365 users, be aware that although Microsoft filters and delivers emails based on DMARC, they do not send the aggregate data for DMARC back to senders.

In the meantime, be sure to set up other important aspects of your Delivery Center subscription, including Configuration, Protection, and Inbox Data.

You can see details about different warnings and errors from our tools on the DNS Problem Details page.

We recommend that you contact your Domain's Registrar to update the name servers on record to include the server that is not listed at the Root Servers.

------------------------------------

Your Primary Name Server was not on the list of name servers given to us by the root.

If your name server is not listed at the root, it could cause impaired/incorrect lookups for your domain.

The Primary Name Server is the name server declared in your SOA file and is usually the name server that reads your records from zone files and is responsible for distributing that data to your secondary name servers. This problem is present when this primary name server is not included in the parent referrals and is almost always accompanied by a Local Parent Mismatch problem.

RFC 1035:

Here a primary name server acquires information about one or more zones by reading master files from its local file system, and answers queries about those zones that arrive from foreign resolvers. [RFC 1035]

If your Primary Name Server is not listed at your Parent or is not responding, then our DNS Propagation test tool will not operate properly. You will most likely also be experiencing other real-world problems with DNS queries for your domain. Users with Basic or Pro accounts can contact our Support Team for assistance with understanding any DNS warnings or errors with specific information about your domain. If you are still a free user, upgrading your account will give you access to support, as well as many other benefits.

Have a great day!

If you receive a DNS change alert from MxToolbox because of TTL changes, no need to panic. These incidents are typically caused by issues at your DNS hosting provider.

DNS TTL (time to live) is a setting that tells your DNS resolver how long to cache a query before requesting a new query. The gathered information is then stored in the cache of the recursive or local resolver for the TTL before it collects new, updated details.

For example, if your DNS TTL is set to 3,600 seconds (60 minutes), the DNS resolver will have to regather the details of a website (mxtoolbox.com) every hour. If 100 users visit our site during that time, they will all see the same visual until the resolvers update their TTL.

The TTL acts as a stopwatch for how long to keep a DNS record because it represents the time each step takes for DNS to cache a record. Recorded in seconds, using the best TTL time for your situation is key to your site's overall responsiveness.

MxToolbox often sees warning signs of issues and outages at DNS providers. Nearly every case is a problem with the specific DNS provider. For example, this outage occurred on May 5th, 2021, and affected customers' domain DNS servers: DNS outage.

To check the propagation of DNS records across your servers and see the selected TTLs, use our DNS Propagation Tool.

If you are receiving alerts for your Mailflow monitor and you are still able to send and receive email, chances are we did not receive a test message back to our system.

Click on the monitor and let it populate in the right window of the page. Under the graph you will see Outages | History | Pings | Edit > Click on Pings.

There are two (2) different results under the Pings table.

1. A message with a Green Check is a successful message returned to us. You can click on the details link and it will provide you the full headers and more information about the test message.
2. A message with a Red X on it is a failed message. If you click on Error, this will show you the test message's subject.

If the message is failing:

• Use the message subject to check that it is not being filtering by an inbound appliance or spam software.
• Use the message subject to check your outbound SMTP logs to see if the message is leaving your gateway.

The reverse IP address name (PTR) is not contained in the server HELO or EHLO banner. In the example below, the string "someotherdomain.com" is not found anywhere in the server banner, which is reporting "example.com". This is only a warning, and in some cases you might not have control over it.

Example of incorrectly matching pair:

220 mx.example.com StrongMail SMTP Service at Wed, 09 Sep 2009 17:00:01 -0700

When a sending server makes a connection to the recipient server, the recipient server notes the sending IP address and performs a reverse lookup. This is done by sending a DNS query, which returns a Fully Qualified Domain Name (FQDN) registered for that IP address. If the sending SMTP address matches the domain, then it is much more likely that the message is legitimate and, therefore, will be passed on to the recipient. If the IP address does not match, it is much more likely that the sending address was spoofed and, therefore, much more likely that it is unwanted and could be considered spam.

A Fully Qualified Domain Name (FQDN) is associated to an IP with a valid PTR record. You want the domain name portion of the FQDN to match the domain of your email address (e.g., If your sending addresses follow the convention of name@mydomain.com, your PTR record should contain something like mailserver.mydomain.com). Only the organization that controls and owns the IP can set a PTR record. PTR record queries are sent to the owner of the IP address, which is the ISP, unlike other DNS queries which are sent to the DNS server of whoever owns the domain. For this reason, setting a PTR record on your own DNS servers is essentially useless since no one is asking your servers.

To make any changes to your rDNS, you will need to contact your ISP. Or, if you host your own DNS (rare), you will adjust it yourself. You will not be able to do this in your DNS control panel unless your ISP also hosts your DNS and gives you the functionality to add your own rDNS records.

We welcome suggestions that can make our SuperTools better. You can submit your suggestions/feedback to us by filling out our feedback form here. We cannot always add your idea, but we love to get feedback! Thank you.

Microsoft has updated the process to set up DKIM for Office 365. Designed to prevent spoofing attacks, DKIM works in tandem with SPF to attain DMARC compliancy. DKIM lets a company add a digital signature to sent emails in the message header, which allows recipient providers to use the signature as a validation point to determine if incoming mail is legitimate.

To enable DKIM for your custom domain in Office 365, complete the steps outlined here: DKIM for Office 365.

To change the email address associated with your MxToolbox account, simply follow the below steps:

1. Log in to your account.
2. Click “username@mxtoolbx.com” in top right corner for dropdown menu.
3. Click “Settings” option directly below username.
4. Enter the new email address you want associated with your account.

Yes, when you are using the Email Header Analyzer tool at the bottom of the page is a link to "Permanently forget this email header".

Clicking this will delete that message from our system. If you have lost the link to your header, we cannot retrieve it. All headers are automatically deleted after 40 days.

If you would like to change your email address, you must actually invite a new user to your account because your users are tied directly to email addresses.

However, this is very easy to do! Note: If your account is configured as a "View Only" account, you will need to ask a user listed as "Editor" or "Owner" to create the invitation.

1. Visit the User Management settings page.
2. Next to the "Invite User" option, type in the email address you would like to invite.
3. Select the level of access you would like to give this new account. Users have Read-Only access to the account, while Editors can make changes.
4. Click "Add User" to send the invitation.
5. Once you accept the invitation and set your password on the new account, you can click "Remove" on the old account to clean it up.

Note: If you are an Owner, you will need to contact Support to transfer ownership to your new account.

There are three permission level roles of access that MxToolbox users can be assigned:

• Owner: Full permissions to modify all account settings. The owner cannot be changed online. If you need to move account ownership to a different user, please contact Support by opening a ticket at the top of this page.
• Edit Access: Full permissions to modify all account settings. Can be removed by other editors or the current owner.
• Read-Only Access: Can read and view only. This permission type cannot make any changes to the account other than modifying their own information.
• Billing-Only: This will create the user as a Read-Only user as well as set their initial Notifications to only receive Billing Reminder notifications.

See current Notifications

User permission levels are set when a new user is invited and can be updated on the Account Management page.

Which actions require Edit Access or higher?

The following is a list of common actions that require Edit Access:

• Adding/editing/deleting monitors
• Adding/removing Delivery Center domains
• Creating/updating notification alert policies
• Activating third-party integrations in Delivery Center
• Updating billing information
• Inviting new users
• And more

MxToolbox supports SMS and Time-based One-time Password (TOTP).

Visit the MFA Settings Page to configure MFA. Note: You will be asked for your password a second time when accessing the MFA page to confirm that you are recently authenticated and should be able to enable or disable MFA on your account.

You can see the MFA status of other users on your account on the Account Management page.

For example, if your mobile phone number is 555-123-4567 and your carrier is AT&T, your SMS address would be 5551234567@txt.att.net. For non-US residents, the address must begin with your country code.

If you use one of the most popular carriers, here are some examples of what your "sender" email will appear as:

• AT&T: phonenumber@txt.att.net
• T-Mobile: phonenumber@tmomail.net
• Sprint: phonenumber@messaging.sprintpcs.com
• Verizon: phonenumber@vtext.com
• Virgin Mobile: phonenumber@vmobl.com

For comprehensive lists of SMS Email Address formats by carrier, see the following tables:

If you use a third-party provider, such as Mailchimp, Mailgun, or SendGrid, to send your outbound emails or marketing campaigns, you can still test your inbox placement pre-send with MxToolbox. Testing your inbox placement is beneficial for your email deliverability and shows you where your messages land: inbox, Spam/Junk, or failed to be delivered.

To set up inbox placement tests with senders like Mailchimp, Mailgun, and SendGrid, click here for more information.

If you're seeing that you're listed on Spam RATS on our site, but you see that other sites, including the Spam RATS site itself show you as not listed that is due to the way Spam RATS handles certain IPs.

In cases of IPs that they are aware belong to providers (such as Google, Microsoft, etc) they may have a poor reputation. In that case, They ARE listed on Spam RATS and we will show them as listed, but do not show as listed on the Spam RATS website.

We have spoken with Spam RATS to let them know of possible confusion.

If you're having email delivery problems, you should speak with our representatives on what steps you can take for better email delivery by using the "Submit a Ticket" button on this page.

1. Please check your usage on our API Page to ensure you are within your API limits.
2. Check rate limiting, if the error returned is 403 HTML response then this is likely due to rate limiting. The rate limit is variable so we can't give you a specific number. Please see our article on Rate Limits and using an exponential backoff.
3. Check your lookup using the "Try It" button on the API Page.
4. Collect the following information and contact our support team (There's a submit ticket at the top of this page):
   
   
   • What IP(s) are the requests coming from?
   • How are you making the calls (single machine, distributed network, an appliance, web/mobile app, etc)?
   • How often are you looking to run lookups? Is this in short bursts, or throughout the day?
   • What is the purpose of the API calls (ie we're trying to check the MX Record of all of our customers)?
   • Have you already implemented an exponential backoff?
   • Which specific API call(s) are you trying to make? Have these calls worked before? Have any other API calls worked for you before?
   • Please provide the exact error you received as the timestamp. Please also include the full url you used for the API call and if you have code you can share with us, please include that as well.

If you are having trouble sending emails from Hubspot to our Inbox Placement addresses, you might need to modify the double opt-in status of those addresses in your Hubspot account. This double opt-in setting, if enabled, requires the email recipient address to have verified that they want to receive Hubspot messages. Our test address network is not able to perform that verification, so if you have double opt-in enabled, you will need to follow the process below to verify those addresses before Hubspot will allow you to send to our Inbox Placement addresses.

How to allow sending from Hubspot to our addresses:

You can update the double opt-in status for your contacts in bulk from your Contacts home. Using the process outlined below will NOT trigger the opt-in email send, but rather will mark the contacts as having confirmed double opt-in.

1. In your HubSpot account, from the top left of the navigation menu, select Contacts > Contacts.
2. You should now see a list of your contacts. Using the search field, search for the Inbox Placement test addresses. They all begin with inbox-placement@ and can also be found in Step 1.
3. After finding those addresses, click the checkboxes next to them.
4. At the top of the table, click the More dropdown menu and select Update double opt-in status.
5. In the dialog box, select the Confirm double opt-in for selected contacts radio button, then click Save.

With those changes implemented, you should now be able to send emails to our Inbox Placement tool. If you need any more information, see the below explanation from this HubSpot article.

About Hubspot Double Opt-in

• When double opt-in is enabled, contacts who have NOT confirmed opt-in will be dropped from any marketing emails, unless your account has data privacy settings turned on and the email includes a subscription confirmation link. This includes new contacts who filled out a form and do NOT click the confirmation link in the double opt-in email, as well as existing contacts who have never received a HubSpot marketing email.
• Contacts who were sent marketing emails from your HubSpot account before double opt-in was enabled will be considered confirmed and remain eligible to receive emails from you.
• Contacts created from an email sent with the HubSpot Sales Chrome extension or HubSpot Sales Outlook add-in will need to confirm their subscription before being included on marketing emails. These contacts will remain eligible for sales emails sent from the contact record.
• Once you have the double opt-in feature enabled, you can manually send an opt-in email to an unconfirmed contact from their contact record. Above the contact name in their contact record, click the Actions dropdown menu, then select Send opt-in email. If the contact has already confirmed their subscription, this opt-in email will NOT be sent.

Please follow the below steps to invite a new billing contact to your account. They will receive monthly or annual invoices from MxToolbox and billing reminders if/when payment issues occur. If you have any billing contact questions, please contact Support by opening a ticket on this page.

1. Log in to your MxToolbox account.
2. Click “username@mxtoolbx.com” in the top right corner to access the drop-down menu or use the following URL:https://mxtoolbox.com/user/account

3. Click the “Settings” option directly below the username.
4. Click the “Account Settings” tab on the black navigation bar.

5. In the Invite User section, enter the email address you want to receive paperless billing invoices.
6. Select the “Billing Only” access level.
7. Click the orange “Send Invitation” button.

8. Your changes have now been saved and billing notices will be sent to the corresponding email address.

Unfortunately, SendGrid is now instructing its customers to add a DMARC TXT Record "v=DMARC1; p=none" when configuring Sender Authentication. SendGrid's page provided to customers from 3rd-Party Vendors is NOT allowing the verification to happen and the vendor needs to verify that MxToolbox's DMARC CNAME setup is correct.

If you use SendGrid and encounter a step to create a DMARC TXT Record during Sender Authentication, MxToolbox offers the following DMARC Integration option:

• DMARC Integration for Delivery Center:

If you are already set up for DMARC with us, your vendor simply needs to verify the Sender Authentication without the replacement or modification of the DMARC Record currently set up. Then, you are good to go.

If you are NOT already set up for DMARC with us, use the above DMARC Integration for improved email delivery. After the integration is complete, your vendor needs to verify the Sender Authentication without the replacement or modification of the DMARC Record currently set up.

MxToolbox's Notifications system keeps you updated on various aspects of your Delivery Center experience. To avoid missing a status or account alert, this feature lets you choose which notifications you want to receive to stay in the know.

Your current settings, subscribed users, and history of all notifications sent regarding your MxToolbox account are all consolidated in a single dashboard view. You can manage Notifications by User or by Type and view Notifications History for the entire account. You can quickly turn on/off different email notifications and monitor who receives them.

With our Notifications system, you can:

1. Set up specific notifications for individual members of your tech team based on their specialties.
2. Limit billing notifications to your billing contacts.
3. Remove unnecessary notifications, alerts, or reports from disinterested users.

To begin selecting which notifications you would like to receive in your inbox, simply click the "Notifications" header toward the bottom of your Delivery Center interface:

At the top of this page, there are three Notifications categories:

Each category is editable and allows you to participate in different aspects of MxToolbox Notifications.

The Notifications by User option lets you choose which parts of the MxToolbox experience you want selected users/team members to receive scheduled alerts for. You can use the none option to decline alerts by category, or you can select the all button if you prefer to receive every available notification via email.

The Delivery Center, Account, Summaries, and Other sections are also editable, so you can pick and choose specific notifications that users will receive alerts for in the future. Be sure to click on the helpful info and link icons (shown below) in each category for more insight.

Note: Some notifications cannot be disabled because they are required for supporting your account.

This Notifications section organizes them by type. You can easily set up multiple team members to receive specific emails or view who is currently allowed to receive them. Plus, you can quickly subscribe/unsubscribe certain teammates to various alerts.

On the left side of the interface, each tab (Delivery Center, Account, Summaries, and Other) lists the corresponding categories of those four headers.

On the right side of the page, the Assigned Users for every notification are provided. If you want to see or change who receives the various types of notification, simply select a specific alert and update the user's access by clicking their corresponding button in the Assigned Users section. Green means that teammate will receive any notifications assigned to them.

The Notifications History page provides a log of all notifications sent to your chosen users, as well as any setting changes that affect notifications. For example, if you want to confirm that an MxToolbox Blacklist Summary report or a Monitoring Alert email was sent to a team member selected to receive those notifications, this interface provides that information. All updates and changes made are conveniently shown here.

Using the shown drop-down menus (Type, Domain, By, For, and Result), you can adjust the data view. These options essentially work as filters.

The table lists different characteristics of every notification for review, including: Date, Topic, Type, Domain, By, For, and Result. They are sortable to give you the desired insight.

If you need help setting up any MxToolbox Notifications, our expert Support Team is ready to get you and your colleagues situated. The corresponding "Help" tab for each category is also a great reference to utilize. Stay informed and start receiving important MxToolbox alerts and communications in your inboxes today!

What Is Bulk Email?

Bulk email, often referred to as marketing or promotional email, is defined as a message sent to a large number of recipients at one time. There are various kinds of bulk email, with the most common being:

• Newsletters
• Sales/discounts campaigns
• Promotional offers
• Marketing campaigns

What Is a Bulk Sender?

If you send a single email to roughly 5,000 contacts in a day, you fall under the bulk sender umbrella. Google set its threshold at 5,000 emails, but Yahoo! has a more liberal interpretation/cutoff.

Basically, if you’re sending a single email to many recipients, you’re considered a bulk sender. It’s important to use email best practices when sending messages because once you’re labeled a bulk sender, you’re always a bulk sender.

Per Google: "A bulk sender is any email sender that sends close to 5,000 messages or more to personal Gmail accounts within a 24-hour period. Messages sent from a primary domain or subdomain both count toward the 5,000 limit.

Sending domains: When Google calculates the 5,000-message limit, they count all messages sent from the same primary domain. For example, every day you send 3,500 messages from yourdomain.com and 1,500 messages from promotions.yourdomain.com to personal Gmail accounts. You’re considered a bulk sender because all 5,000 messages were sent from the same primary domain: yourdomain.com."

Again, senders who meet the above criteria at least once are permanently considered bulk senders.

Per Yahoo: "In order to better enforce anti-spam policies, Yahoo does not disclose the number of recipients or emails that can be sent at one time.

If you've received a notification that a limit has been met, you'll need to wait a set amount of time before you can send more emails. Most sending limit notifications inform you of how long you'll have to wait.

If you're planning to regularly send bulk email, consider looking into alternate solutions, like a third-party bulk email option."

What Is Transactional Email?

Transactional emails are messages sent in response to an action a user/customer takes on a specific site, app, or interface. These emails contain content that’s specific to that user, and are typically sent as stand-alone messages. Common examples include:

• Password reset emails
• Payment invoices
• Account creation/activation emails
• Shipping confirmations
• Welcome emails
• Purchase receipts
• Order confirmation emails
• Reservation confirmations

Transactional emails are a common and accepted practice. Recipients typically expect to receive them when completing certain online actions as part of a confirmation process.

In short, content and purpose distinguish bulk emails from transactional emails. Transactional messages contain information regarding an action the recipient has already taken. Conversely, bulk emails try to persuade the recipient to complete an action beneficial to the sender.

FAQs

Q: Are billing/payment invoices transactional?
A: Yes, invoices are considered to be in the transactional email category.

Q: What about reminders or other notifications that come from my system?
A: Yes, any reminders or notifications from your system are transactional email.

Q: Ads in transactional emails? What if I have a banner ad for something included in my invoices?
A: Transactional emails should NOT contain any marketing or bulk content in order to comply with commercial email laws like the CAN-SPAM Act. It’s always recommended to separate bulk emails from transactional emails.

Q: Do all messages require one-click unsubscribe?
A: Per Google: "No. One-click unsubscribe is required only for marketing (bulk) and promotional messages. Transactional messages are excluded from this requirement (e.g., password reset messages, reservation confirmations, and form submission confirmations).

Senders that already include an unsubscribe link in their messages have until June 1, 2024 to implement one-click unsubscribe in all bulk emails."
