Overview
Whether you’re using a local editor or your email service provider’s email editor to create emails, Litmus Extension lets you personalize, preview, troubleshoot, and optimize your email right where you build, saving you time and helping you boost email accuracy & engagement.
You can download the Litmus Extension for free, but it requires a paid Litmus account for full access to pre-send email testing and personalization.
