How to Set Up/Modify SPF for Infusionsoft

The following description addresses how to update a Domain Name Service (DNS) record to use SPF with your custom domain in Infusionsoft.

To utilize a custom domain, the Infusionsoft provider requires an SPF TXT record be added to the DNS record. This TXT record is then used by DNS to recognize email servers allowed to send messages on behalf of your custom/third-party domain. To determine whether a correspondence from the specified domain comes from an authorized messaging server, the recipient system relies on the implemented SPF TXT record. At that point, the message is either accepted, quarantined, or rejected by the email receiving system.

To implement SPF authentication for your domain, you will need access to your DNS records in the domain hosting account. Important: If you already have an SPF record, then you should modify that existing record. You must not have more than one SPF record.

For convenience, be sure to log in to your Infusionsoft account to verify your domain and copy your TXT records. Infusionsoft utilizes an include mechanism during the set-up process. For example, the following scenario is the most common and would pass SPF:

v=spf1 ~all

If you send email from IP for the domain “” and that domain’s SPF record includes and the IP address passes the SPF record, this mechanism will pass.

As mentioned, if you already have an SPF record set up (and because only one SPF record is allowed per domain), you can simply add a reference to Infusionsoft to it. For example, instead of having two separate records, combine them into one:

v=spf1 ~all

How to Set Up/Modify DKIM for Infusionsoft

Infusionsoft allows DKIM authentication and creates the necessary keys on your behalf, leaving you responsible for only the CNAME record in your DNS. Email service providers that support DKIM check inbound email to verify whether an organization that claimed to have signed a message actually did. To create a DKIM record for your domain name, do the following:

1. Log in to your Infusionsoft account

2. Go to Marketing > Settings > Email Authorization

3. Click Add a Domain button

4. In window, select domain you want to create DKIM key for in dropdown menu

5. Next, follow steps that appear on screen []

6. Click Verify button to validate CNAME record created

7. Once domain is verified, Infusionsoft will include DKIM when sending emails on your behalf

As a user of this outbound email provider, Infusionsoft customers are afforded DKIM signing because it supports that mechanism. By utilizing Infusionsoft’s self-service portal, you can manually set up DKIM at your convenience via CNAME records mentioned above. Overall, this Infusionsoft product provides beneficial components (e.g., DKIM signing, custom DKIM records, self-service set up with CNAME records) that result in a streamlined process.
