Sender Authentication monitoring guide

Sender Authentication in Litmus Email Guardian automatically monitors your authentication protocols across all of your sending domains. When properly configured, authentication increases the likelihood that your emails will be delivered to your subscribers’ inbox rather than being marked as spam or rejected. Setting up sender authentication is simple!

NOTE: Sender Authentication is available in Early Access on Enterprise plans.

Start authentication monitoring

Navigate to the Sender Authentication tab under the Monitor tab

There are two ways to start authentication monitoring:

  • Upload an .eml (electronic mail format ) file of your email
  • Add your unique seed address to your Email Service Provider subscriber lists (recommended)

copy monitoring address or upload email

We highly recommend you copy your unique authentication monitoring address and include it in your Email service provider subscriber send lists. We use this address to check your send from domain authentication and alert you of any issues automatically for each send.

NOTE: Sender Authentication submits your email categorized as marketing so you may receive alerts for missing List-Unsubscribe headers. These headers are not required for transactional emails. You can disregard the alert in these instances.

Delete domains, manage notifications, or edit your seed address

Click the manage domains option on the Authentication Monitoring page

From here, you can delete domains you no longer want to monitor. If you need to update or change your seed address used for monitoring, you can do that under the "update your monitoring email address" section

configure your monitoring address

Note: Your monitoring address is account-wide. If you change the address it will change for each user.

To manage notifications, click the manage domains option on the Authentication Monitoring page or you can find the notification under the notification tab under settings

NOTE: You might see domains that you don't recognize in your list. We pull in in domains associated with your sending domain. In some cases, different domains can handle different aspects of your authentication.

When under a specific domain check, you have the option to share check details. This creates a public link that allows you to share the whole domain check with anyone.
