Email preview is super important for me. I use 3 email senders but none of them give me the visuals of subject at a device level. I used to test it on my own mobiles. But this extension allows you to test the visual of subject line from multiple screen size and devices.

Refresh your page twice using control + F5. This usually clears the cache. If that doesn't work try right clicking your browser and click on inspect element. If neither works, uninstall and reinstall the extension or feel free to reach out to us on firstname.lastname@example.org
