Overall Satisfaction with Litmus

I use Litmus primarily to render check Email Marketing Campaigns. I sometimes use it for spam testing and deliverability analysis.
  • Litmus provides very accurate screenshots of email renderings across a wide range of devices
  • Litmus provides helpful tips for improving subject line content
  • Litmus has a multitude of blog articles that are helpful in designing or troubleshooting effective marketing emails.
  • The Microsoft Outlook for iPhone render test is usually not accurate. It shows the email to be broken or misaligned when it actually renders perfectly when tested on a real device.
  • The latest or most current versions of devices or email clients are not always available.
  • time saved not needing to manually test emails
  • deeper visibility into email deliverability and performance metrics
It saves a lot of time not having to send proof to Litmus by being able to see the same test results right there on the platform.
It is a great reference source for us when making recommendations to clients. We can show them Litmus results to back up our recommendations, and it doesn't look like we're just making this stuff up.
As far as email render testing goes, Litmus and Email on Acid are pretty similar. However, I would say that I prefer Litmus for checking subject line emojis and that Litmus is a bit more robust with some of its other tools like spam test, email builder, etc. And the fact it can be integrated into a number of different marketing platforms adds even more value.

Do you think Litmus delivers good value for the price?

Would you buy Litmus again?


It is well suited for testing MS Outlook and Gmail (desktop and mobile app), and pretty much all Apple and browser-based email clients. The only scenario I don't find appropriate is testing MS Outlook mobile. I have found it to be helpful, but sometimes unreliable for testing emojis in subject lines. Some emojis appear to be non-supported by certain email clients when tested on Litmus. However, they showed up fine on those clients when checked on a real device.
