"Love Litmus"
What do you like best about Litmus?

Litmus is extremely easy to use -and extremely important for anyone sending an email. They have a great platform for checking client rendering, suggesting best practices, as well as workflow help with Litmus Proof and deeper analytics insights with their tokening of campaigns. On top of that, they have a wonderful blog, host webinars, and have a conference as well.

What do you dislike about Litmus?

They recently addressed the one pain point I had with being able to push a single email from code to all of the other tabs.

What problems is Litmus solving and how is that benefiting you?

We are catching problems before they arise - allows us to mitigate the chance that something broken goes out. We've also been able to realize deeper insights from the analytics feature.

"Love, love, love LITMUS!"
What do you like best about Litmus?

I feel like it's just the industry standard of what email should be. Along with really good emails their one of the few voices that preach the importance of email, especially accessibility. Beyond that their tool is really just solid in terms of testing different email clients, even their WYSIWYG editor is good.

What do you dislike about Litmus?

We haven't really been able to utilize their tracking & analytics because of how our emails are built we're not really able to take advantage of it.

What problems is Litmus solving and how is that benefiting you?

Email accessibility.

"Easy to use, powerful tool"
What do you like best about Litmus?

The newsletter of industry updates I find to be a very quick and easy tool for relevant items in the email world. The platform itself is very easy to use and powerful to ensure you're getting the most out of your email performance

What do you dislike about Litmus?

There are some features left to be desired within email list management.

What problems is Litmus solving and how is that benefiting you?

inbox rendering for the most part. We've caught small, but potentially impactful, issues within our email code base via Litmus.

"A great email rendering service"
What do you like best about Litmus?

The best thing about litmus is the fact that they display rendering of how our email will look on every email client that is important to us. There have been other services I have used that do not have all email clients on them.

What do you dislike about Litmus?

There is nothing I dislike about litmus. They have a great platform. The only criticism, and s subjective one, is that it is a pricey service for small businesses.

What problems is Litmus solving and how is that benefiting you?

We have solved the issue of sending out emails that do not look how we intended them to on different email clients, or worse yet, are broken.

"Best Email Screening Software I Have Used"
What do you like best about Litmus?

The UI. Very easy to use! I like to use Litmus because even those that are unfamiliar with testing software, it is easy to use and setup.

What do you dislike about Litmus?

It is a bit pricy but it's worth it. There are other solutions out there that is half the cost of Litmus but they are not as accurate or fast as Litmus.

What problems is Litmus solving and how is that benefiting you?

Before I send out an email, I always use an email screening software. Litmus always gives me accurate screenshots of the email and finds any potential issues I may have with my email.

"Check inbox placement and style within a few clicks"
What do you like best about Litmus?

I really like how I can connect this app to Eloqua and perform inbox placement, spam test and check to see what the look/feel of my emails will be on just about every platform you can imagine, desktop and mobile. IT also has a spam check feature that allows you to check on your IP's helath and how your email will land in your recipient's inbox (placement check), it's saved me many times from sending out an emial when ther might be something off about either my IP being temporarily blacklisted or perhaps a title that's raising flags (bad use of keywords and/or punctuation marks).

What do you dislike about Litmus?

Could integrate a little better with Eloqua (allow me to search for an email and not just use one that I've recently accessed in Eloqua).

What problems is Litmus solving and how is that benefiting you?

It's incredibly easy to see what platforms need additional attention/coding when creating my emails. Overall it's helped my design better emails, test them more thoroughly, and analyze areas that I could improve upon that may be lacking.

"Extremely convenient tool for email testing"
What do you like best about Litmus?

Litmus is really good in the sense that it eliminates a lot of manual review of emails and renders emails on how it looks in different devices. A great time saver. Several features available though the most useful is sending the test email to a provided litmus id and validating it real time

What do you dislike about Litmus?

I would be really happy if litmus has rendering options for a few more devices . That would make it easier for email template verification

What problems is Litmus solving and how is that benefiting you?

Email template rendering verification. Its a great time saver. Helps review email being sent in different browsers and devices instead of manually checking in everything
