Reach the inbox, not the spam folder

Quickly identify potential issues preventing your email from being delivered, and use actionable in-product advice to fix them.

It took us less than 48 hours to identify and fix our issue, and to get removed from the blacklists. Without Litmus, we wouldn’t have known where to start.

Maximize ROI with advanced analytics

Discover which email clients are popular with your audience to fine-tune testing efforts, and utilize engagement and geographic data to inform segmentation, design, and send time decisions.
