Jimmy Mona (ID: 0000009410e9a238) Voted 3 ★ - Updated 04/11/2018 The tests show up fine when using the extension, but when I test the same emails on the litmus website they look different and there are bugs I need to work out, so it defeats the purpose of the extension. It seems to have somethings to do with eloqua field merges not rendering properly. So may only affect people using Eloqua

Charlton S (ID: 000000e9a2ef9fa0) Voted 3 ★ - Updated 11/13/2017 A bit buggy. Having issues with the app not letting me scroll up after I scroll all the way down. I have to either refresh my entire browser session or kill the app and restart for it to work again. The scrolling feature also gets stuck at the top after I run a litmus test. I'll stick to the normal web app for now.

Kevin Cassidy (ID: 0000008a7e16b7d7) Voted 2 ★ - Updated 08/24/2017 Nice app! But there are a huge amount of Console Errors. They need to be fixed before I could condone it being used by my team.

Veronica Braxton (ID: 00000012b5d033aa) Voted 5 ★ - Updated 08/23/2017 Just simply, amazing. I Love Litmus!

Daniel Brown (ID: 000000bb28fe7f7a) Voted 5 ★ - Updated 01/13/2017 Ever wished you could code an email in your favorite text editor, preview it in your browser of choice and then with the click of a button check your email’s rendering in up to 70 email clients? Well, good news! Litmus' new browser extension will allow you to do exactly that and it’s as magical and useful as it sounds. Litmus has long been an essential tool in my development toolbox and now I can’t imagine living without their browser extension.
