DKIM & SPF Setup for SendinBlue

To set up or edit your SPF record, you will need to add: include:sendinblue.com

Edit existing SPF record

1. Log in to your DNS hosting provider
2. Look for a TXT containing v=spf1
3. In your existing SPF record, you will append include:spf.sendinblue.com
4. For example, if your existing record looks like v=spf1; mx; ip4:1.2.3.4; you would add the above include as follows v=spf1; mx; ip4:1.2.3.4; include:sendinblue.com

Create a new SPF record

1. Follow the instructions from our How to Create a New SPF Record Guide.
2. In the Value field, enter: v=spf1 include:sendinblue.com ~all and Save the TXT record.

Records for Subdomains

If you are creating a record for a subdomain, you will want to make sure that you specify the sub part of the domain in the Host/Name/Alias field for most DNS providers.

1. Enter the sub part of the domain, for example if the subdomain is mail.mxtoolbox.com you would want to enter mail into that field.

SPF and DMARC Alignment

By default, SendinBlue will set you up for sending using one of their domains for the return-path address. This domain will NOT pass SPF Alignment. At this time, this provider does NOT provide any mechanism that will allow SPF Alignment to pass. You need to enable DKIM for this provider to ensure your email will pass DMARC Compliance.

How to Set Up/Modify DKIM for SendinBlue

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 customized DKIM record for your domain name, do the following:

1. Go to Settings

2. In the Your Senders box, click Configure

3. View list of domains and select domain you want to sign your emails (or create one)

4. Click Manage tab

5. Select Edit from dropdown menu

6. Sender Editing window opens; default setting signs your emails with domain name associated with dedicated IP address

7. Customize your DKIM signature by checking the box (I would like to use this domain name to sign my emails)

8. Enter preferred signing domain name

9. Click Save

10. Once you see green check appear, click Done
