MailerLite SPF and DKIM Configuration: Step by Step

MailerLite is an email marketing tool and website builder for businesses of all shapes and sizes. The key idea behind MailerLite is simplicity. We provide our customers with straightforward and user-friendly tools such as a Drag & drop email editor, a website builder, and an intuitive subscriber management interface.

The DKIM and SPF records given to you on the Domains page cannot be changed within MailerLite and the exact records must be added to your DNS page for the authentication to work.

1. Login into your MailerLite account.
2. Head to the Account settings page and select the Domains tab as in the screenshot below.

Enter the email address you wish to use to send emails from and click Save as in the screenshot below.

3. Once you receive the confirmation email, click on the Confirm my email address link.

4. You will see a success message confirming the domain verification.

How to authenticate your domain

1. Head to the Settings page and select the Domains tab.
2. Click on Authenticate for a verified domain, or Add a domain for an unverified one (and then click on Send confirmation email). 

You’ll get the Name and Value fields for the DKIM and SPF records of this domain as in the screenshot below.

4. Add the DKIM as a CNAME record and the SPF as a TXT record with their respective Name and Value fields that you have received from the pop-up window into your DNS zone.

Note: It’s only possible to have one SPF record on your DNS zone. If you have more than one, they need to be merged.

5. Now after adding the provided records to your DNS head back to your MailerLite Domain Authentication tab and click on Check DNS Records.
6. Once everything is added properly, you will be able to see a checkmark under the Authentication part as in the screenshot below.

Congrats, you’ve successfully set up your MailerLite SPF and DKIM!
