Authenticate your sender domain

Authenticate your email domain

To improve delivery of emails from your own email address you need to authenticate your email domain. It is easier than it sounds. This guide will show you how to do it in a few easy steps.

Pick an email address

If you have signed up with a free email address like gmail.com or yahoo.com you need to add an email address where you can access the DNS settings.

Go to your Email settings on Minutemailer and add the email address you want to send from. We will send an email to verify it's your email address, so make sure you can receive emails to the email address you added.

Locate your DNS

To authenticate your sender domain you need to add some info to your domains DNS settings. So if you want to send from info@example.com you need to access the DNS settings for example.com. Usually it's located in the control panel of your web host.

Get your settings

Go to your Email settings on Minutemailer. Locate the section Authenticate your domain. Click Authenticate to the right of your domain name. You will get a short explanation and then you will see the domain DNS settings.

DNS settings at Minutemailer

There are three settings you need to add. For each setting there are two fields you need to copy from Minutemailer. Subdomain and Value.

Adding the settings

How to add the settings depend on where your domain is hosted but usually you can find it when you login under DNS settings on your web host.

  1. Choose Create CNAME or Create DNS post (exact wording varies)
  2. Select CNAME as type if it's not already selected
  3. Copy the field Subdomain from Minutemailer into the field Subdomain or Name. It should be the first field. Sometimes you need to add a punctuation after the subdomain.
  4. Copy the field Value from Minutemailer into the field Value or is an alias for.
  5. You also need to set TTL (Time to Live). Which can be set to 300 or what your hosting provider recommends.

It can take up to a few hours for the settings to take effect. You can click the Validate button to check if it has gone trough. You will see that there is a green Authenticated text on your accounts email settings when its done.

Successfully authenticated DNS settings

IMPORTANT: When your domain is authenticated let the data you added to your DNS be. Don’t remove it. If you do the authentication will stop working.

Good luck with your emails and let us know if you run into any problems!
