Doesn't work with Pardot/Account Engagement even though it says it does on my Plan benefits...
was a big fan, until they stopped supporting images loading from local source. Now the desktop app is virtually useless.
Not possible to switch between different lists when testing manually.
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
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.
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.
Just simply, amazing. I Love Litmus!
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.
As an Email Developer, I’ve always worked locally when it comes to my HTML. The litmus extension makes it extremely fluid when working on and making changes to an email. It's amazing how it's filled in the biggest gap with local development and litmus testing. It has also created this perfect flow of sending an email to testing after finishing a build.
I'm an email developer at the Dollar Shave Club, and I use the Litmus Chrome Extension every day! I love the flexibility it offers for working with local files, whether it’s a hand-built HTML file or one rendered on a localhost by my build pipeline. It gives me the shortest possible feedback loop so that I can build, troubleshoot, and hack to my heart’s content. It definitely helps me shave down my dev time. Pun intended.
