Litmus Launches New Email Testing Solution: Email Guardian

Published: January 16, 2024

Litmus is designed to help marketers create, personalize, test, review and analyze every email send by providing a better way to build and test every outgoing message.

The Lowdown

Litmus Email Guardian proactively monitors all emails — such as templates and transactional sends — to help users fix costly, brand-damaging errors before every send.

Back-Of-The-Box Details

Email Guardian is designed to help marketers keep a constant pulse on how external factors, like email client changes or image hosting issues, impact how their emails display. It is said to be the only solution that proactively monitors how emails render across key email clients, alerting users to any changes before they reach subscribers.

Who It’s For

Email developers face tight deadlines and lack insight into post-testing client changes. Marketing managers need flawless delivery to maintain subscriber growth, engagement and overall campaign success. Marketing leaders need to protect their brand reputation across all channels. Email Guardian seeks to solve these challenges and ensure successful email campaigns.

What It Solves

Email clients change every day without notice, and each change puts emails at risk of breaking, resulting in a poor subscriber experience. The impact on brand trust can be costly to a company’s bottom line, decreasing engagement across channels.

What Makes It Special

According to the company, it is the only solution that monitors emails 24/7, giving marketers peace of mind that their emails are constantly protected and ready to drive revenue.
