Introducing Instant Previews + Checklist: Send With Confidence Every Time


At Litmus we want to make email testing easier. We want you to be able to send with confidence every time.

To help get you closer to that goal, I’m thrilled to introduce two major new improvements: Instant Previews and Checklist. Once you try them for yourself you’ll see how you can spend less time fixing problems and more time creating new possibilities with email.

Instant Previews: Get screenshots in seconds

Testing emails manually takes hours. Using Litmus always cut this down to mere minutes, but after this latest update previews now take just seconds. Making sure your email looks great in every client and device has never been easier (or faster!).


Checklist: Take the fear out of pressing send

At Litmus we’ve sent hundreds of emails. And over the years, we’ve watched you send millions. By monitoring for problems in all these emails—and noticing what works—we’ve been able to distill 10 years of research and learning into a new product: Checklist.

Within Checklist you’ll find:

  • Tips for optimizing your from name, subject line, and preview text
  • Instant previews of your email in popular inboxes
  • An actual checklist of improvements to ensure links, images, and tracking work properly.

Checklist gives you the confidence to press send.

Builder: Build, test & troubleshoot in real time

Tired of bouncing between your code editor, mailing platform, and Litmus? So were we. Now you can build your email in our web-based editor, Builder, and get instant previews in 40+ email clients as you go.

It’s a transformational way to build emails. Pre-launch we showed this to people at our conferences and they were knocked out. I can’t wait for you to try it.
