How to authenticate a domain with Wix

This article is meant for those who already have a domain successfully registered with Wix. You'll need this registration as long as you use the domain name, even when you authenticate it with MailerLite.

  1. Head to Domains.

  1. Click Add domain.

  2. Enter the email address you wish to use to send emails from and click Send verification email. Verify your email address with the confirmation email we send you, or immediately authenticate your domain to automatically verify your email.

  1. Once the domain has been added, click on the Authenticate button. You’ll get the Name and Value fields for the DKIM and SPF records. Copy these fields and keep this page open.

  1. Head to Wix and navigate to your Dashboard page. Make sure you select the website that you would like to authenticate. 

  2. On the left-hand sidebar, click on Settings and then select Domains

  3. On the section of the domain you would like to authenticate, click on the three dots to the right, and select Manage DNS Records from the dropdown menu.

  1. On the Manage DNS Records page, click on + Add Record under the TXT (Text) section.

  2. In the Host Name field box, add ml._domainkey only. Do not add the name of your domain since this is already automatically included in the record.

  3. In the Value field box, paste the DKIM Value text that is given to you in your MailerLite account.

  4. Leave the TTL at one Hour.

  5. Click Save.

  1. On the Manage DNS Records page, click on + Add Record under the TXT (Text) section.

  2. Unless you're adding a subdomain, leave the Host Name field box empty as the name of your domain is already automatically included in the record.

  3. In the Value field box, paste the SPF Value text that is given to you in your MailerLite account.

  4. Leave the TTL at one hour.

  5. Click Save.

Note: Do not add the SPF record in the SPF section of the DNS page on Wix, otherwise our server won’t be able to recognize the SPF record.

Head back to your MailerLite Domains page and click on the green Check DNS records button located below the records.

Once both records have been approved, you'll get notified.

However, sometimes the site could show that one or both records were not approved, even if all of the information was correctly submitted. 

There are two 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 re-checked and updated. 

Even if you think you are sure you set up the information correctly, we suggest that you follow the troubleshooting steps below, just in case.

DKIM record is not approved

If the DKIM record fails, first check if you have typed only ml._domainkey (without your domain) in the Host field. Then check if both Value fields are exactly the same (they’re case-sensitive). 

If you’re unsure, you can check both texts here.

SPF record is not approved

There are two reasons why an SPF record is not approved:

  • SPF records don't match

  • More than one SPF record was found

SPF records don’t match

  • Check that the Host Name field is empty and is not your domain. 

  • Check if the Value field on your Wix DNS page is exactly the same as the one on your MailerLite Domains page. They have to be identical as they are case-sensitive. The record won’t be approved otherwise. 

You can use this site to compare both texts.

More than one SPF record was found

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

In the picture below, there are two different TXT records for SPF. Both of these need to be merged into one single record.

Fortunately, MailerLite does this for you after you click once on the green Check DNS records button. This allows the site to check and update the SPF record’s Value with the merged version after clicking on it. The updated SPF Value will be available on the same pop-up page.

At first, you will notice that the SPF Value record will look something like this:

v=spf1 a mx include:_spf.mlsend.com ?all

After clicking on the green Check DNS records button and receiving the error message that more than one SPF record has been found, refresh the page, click on the Check status button, and most likely, you will see that there is a new merged value for the SPF record. 

You can confirm this by examining it. The merge was successful if the text includes more than one include.

An example of a merged SPF record from MailerLite and Outlook:

v=spf1 a mx include:_spf.mlsend.com include:spf.protection.outlook.com -all

Before setting up the new merged SPF record, it’s important to:

  • Remove all of the current SPF records on your Wix DNS zone, including the original one from MailerLite that is not merged.

  • Add a new TXT record with the merged SPF record.

  • Go back to your MailerLite Domains page and click on the green Check DNS records button.

An error may still come up even after setting up the merged SPF record in the DNS zone. Don’t worry if this happens. Remember that servers can take up to 24 hours to completely update this information. Most of the time, however, it’s approved within a few minutes to a few hours.

You can check if the SPF record is correctly set up using this third-party tool.
