Litmus

What I really like most is the ability to generate email previews across a number of different email clients, so that it helps to optimize the look and design of email templates - this has been super helpful for our marketing team.

There are a few features that would be nice to have included the basic subscription, such as the ability to test an html email for potential spam delivery - while it is a feature that we really like, we often feel like it should be part of the basic package in case we decide to go a level down in our subscription.

Litmus is a very collaborative tool for building templates, sorting out the issues in the code, and implementing responsive templates. Modules can be incorporated. Brand designs and colors can be set up. Plus, the performance of your organization can be evaluated. It also helps users to confirm if their email is going to give a cool look on all devices. The builder part of the app is just mind-blowing.

A live builder option that is currently not available should help a lot. For instance, if one is asking for changes in the code, he should be able to see the changes correspondingly to have a better idea of what could be the best option. Apart from that, many features of Litmus do not fit in our workflow. I can understand that many people might find them useful but part of our payments goes to those features which are not assisting us in any way. So, a solution must be found for such discrepancies.

I'm a huge fan of the multiple platforms for testing emails- desktop, mobile, etc. They keep their testing suite up to date with all the new build releases for iOS and Android and you can run through the different potential platforms all at once with a single test. There's also pretty good engagement insight and A/B testing functionality. The interface is very intuitive so the tool is handy for getting more folks involved in the actual testing process without a complicated onboarding.

The intended use applications are great, my only "complaint" is with the data retention aspects. While Litmus has very clean compliance documentation, if you receive a data deletion request, the effectuation insofar as Litmus is a little manual/pedantic. But it's not unworkable.
