Deliverability testing and inbox monitoring

Litmus Spam Testing runs a comprehensive suite of checks to validate your authentication records, check blocklists, and evaluate your email across major spam filters and inbox providers to detect any issues before you send.

Litmus shares tips and best practices based on the results of your pre-send spam tests and gives you results of your reputation and spam filter results at the time of your test.

Litmus Email Guardian continuously monitors emails you select and can alert you to changes in email clients that affect your email's presentation, and, for Enterprise plan teams, on-going checks of your domain reputation.

We recommend running a Spam Test before each send to catch any issues that may affect your ability to reach the inbox before you send.
