This article is meant for those who already successfully registered a domain with Cloudflare.

How to add a domain to MailerLite

1. Head to the Account settings page and click the Domains tab.

2. Under Sending domains, click Add domain.

3. Enter an email address that includes your paid domain, which will be used to send campaigns.

4. Click Save.

Note: It is not necessary to have a website attached to your domain, but you will need to have an email address that uses that domain, as this will be ideal for sending. If your domain is example.com, your email may look something like newsletter@example.com

Does MailerLite provide an email address?

It is not currently an option to purchase an email address or host a domain in MailerLite. To connect a domain and matching email address for sending, they will first need to be set up with a hosting provider. 

Some trustworthy hosting providers are Godaddy, Cloudflare, and Bluehost. For an email address, we highly recommend using Squarespace Domains, which allows you to create an email address with your own domain.

5. Check your inbox for the verification email and follow the steps to verify the email address. 

6. Once the domain has been added, click on the Authenticate button. A window will appear containing Name and Value fields your DKIM and SPF records. Copy these fields and keep this page open.

How to access the DNS zone page on Cloudflare

5. Click Save.

Proxy status - make sure that MailerLite records are set to “DNS only” and NOT “proxied” as they will only be accepted by MailerLite if they are set to DNS only.

How to add the SPF record

2. Choose record type. For the SPF record, make sure to use the “TXT” type.

3. In the Name field, enter @ and paste the value of your SPF record in the Content box.

See How to merge SPF records.

How to get the DKIM and SPF records approved

Head back to your MailerLite Domains page and click on the green Check DNS records button on the domain authentication window. Once both records are approved, your new domain will be displayed as Authenticated ✅.

In some cases, it may appear that one or both records were not approved even if all of the information was correctly submitted. 

There are 2 reasons why this happens:

  1. It can take the servers up to 24 hours to completely update this information. Most of the time, however, the DKIM record is approved and updated in a matter of minutes.

  2. Some information has to be re-checked and updated.
