In short, domain authentication allows servers of the world to know that the email address you use to send emails is really yours. For you it means that your email is less likely to bounce or end up in your readers' spam boxes. Though the one-time setup can be a bit challenging, it’s more than worth setting it up. We’ll show you how!
To start the authentication process, go to the top right drop-down menu and click Authentication. The standard settings should work fine if you don’t have access to your current domain. However, if you want that extra delivery boost, press I’ll manage my own authentication. Here, you can add (and delete) several domains that you are planning to send from.
Make sure you add your domain without the www. or http://. So just mailerlite.com, for example.
After you finish adding your domain, you will see your generated records.
Now go ahead and login to your hosting panel (where you registered or parked your domain name). This could be Namecheap, GoDaddy, or any company you have used to buy your domain and/or hosting package from.
Copy the codes and insert them in your DNS records. Ask the customer support of your hosting company or us to help you with this if you don’t know how to do this.
In some cases, you need to add a dot “.” at the end of the TXT name, but this depends on your hosting company.
It can take up to 48 hours for the servers to see your updates, so sometimes you need to wait a little for the results to show up.
