Namecheap step-by-step domain authentication

Note: If you're a Legacy (Classic) user, please log in to your account to access the dedicated Legacy (Classic) Help Center. 

This article is for those who have already successfully registered a domain with Namecheap. 

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

  2. Under Sending domains, click + Add sending domain.

  3. Enter the email address you wish to use to send emails from.

  4. Click Save.

  1. A popup will appear, prompting you to start the authentication process. Click Continue.

This tool will scan your domain and detect which provider is the host. 

  1. Once the provider has been detected, follow the instructions to connect to your account. You will need to use your login credentials to log in to your hosting provider.

What if I do not have the login details?

By choosing the option Connect a different way > Send login link to admin, you can share a link with someone who has the details to log in, so they can complete this part of the process.

  1. Next, follow the steps to authorize MailerLite to configure your DNS and add the necessary records.

  2. Once the DNS configuration is successful, you will be redirected back to MailerLite. Refresh the page to see the updated status of your domain.

It can take up to 24 hours for your new DNS records to propagate and for your domain to be authenticated. You will see the Authentication in process status first, which will change to Authenticated once the process is completed.

If you would like to access the DNS records and authenticate in Namecheap manually, click Authenticate manually.

You’ll be presented with instructions for manual authentication. Before starting, head over to Namecheap and log in to your account. To access the DNS zone page:

⚠️ According to Namecheap’s documentation, it is only possible to set up TXT, SPF, DKIM, and DMARC records in your Namecheap account if your domain is pointed to BasicDNS, PremiumDNS, or FreeDNS hosting.

If your domain is pointed to Namecheap Web Hosting DNS, you can add the DNS records in your cPanel.

  1. Click Domain List on the left-side menu.

  2. Find the domain you wish to authenticate and click Manage.

  1. Select the Advanced DNS tab.

On MailerLite’s side, click Add record next to the DKIM CNAME record. Then click the ✔️ I’m logged in button to proceed.

On MailerLite, click Add record and confirm ✔️ I’m logged in. Afterwards, on Namecheap:

  1. Click Add new record.

  2. Choose CNAME as the record Type.

  3. In the Host field, enter litesrv._domainkey.

  4. In the Value field, enter litesrv._domainkey.mlsend.com.

  5. Leave TTL as Automatic.

  6. Click Save all changes.

Once the record is added, head back to MailerLite and click ✔️ I added the record.

On MailerLite, click Add record. Afterwards, on Namecheap:

  1. Click Add new record.

  2. Choose TXT as the record Type.

  3. In the Host field, enter @.

  4. In the Value field, enter the SPF value given to you in your MailerLite account.

  5. Leave TTL as Automatic.

  6. Click Save changes.

Once the record is added, head back to MailerLite and click ✔️ I added the record.

Note: There should be only one SPF record added at a time. If you have another SPF record in your DNS zone (value starts with v=spf1…), make sure to delete it. The record provided by MailerLite will cover all of your services.

On MailerLite, click Add record. Afterwards, on Namecheap:

  1. Click Add new record.

  2. Choose TXT as the record Type.

  3. In the Host field, enter @.

  4. In the Value field, enter the verification value given to you in your MailerLite account.

  5. Leave TTL as Automatic.

  6. Click Save changes.

Once the record is added, head back to MailerLite and click ✔️ I added the record.

Once the records are approved, your domain status will be displayed as ✅ Authenticated.

In some cases, it may appear that the 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, it is approved and updated in a matter of minutes.

  2. Some information has to be rechecked and updated.
