"Awesome company"
What do you like best about Litmus?

They have such valuable and fun newsletters to read and webinars that they put on. The customer service is stellar. They get back to you quickly. I'm always discovering new tools that they come out with.

What do you dislike about Litmus?

It seems like when I zoom into the previews, they come up in a different order than they are in the smaller view and then I kind of lose my place.

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

I mostly use it to resolve rendering issues which Litmus is fantastic for. They also provide so many helpful tools and tips just generally about email.

"Flexible Email Updating & Testing Tool"
What do you like best about Litmus?

Litmus can show how your email will render across countless email clients. Renderings can be so different and finicky across email providers that this is a marketers dream. No more making two dozen fake email accounts to see how emails will look...

What do you dislike about Litmus?

It's great for basic editing and html updates but there is no WYSIWYG editor for building emails from scratch.

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

Being able to test across multiple email clients at once is worth it's weight in gold. Html edits are also easier because it let's us highlight regions we need to update.

"Litmus is so user-friendly and has great customer service!"
What do you like best about Litmus?

I love how I can add a client to Litmus, share an email with them, and I don't even have to walk them through it. It's so easy to use and is excellent for multiple clients.

What do you dislike about Litmus?

I haven't found anything I don't like about Litmus.

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

Email proofing, it is easy to add clients to single emails or folders, depending on creating one or several emails. I love how specific you can make the edits as well. Most proofing systems are not this simple to use.

What do you dislike about Litmus?

I've never found a good way to auto-format my line breaks.

Litmus has helped our business ensure that our emails look good no matter what device they are viewed from. It has also helped us optimize our emails for dark mode. It's also helped us create templates and snippets that we can reuse easily for multiple different emails.

"A tool to help give visibility without breaking the bank"
What do you like best about Litmus?

The ability to easily pass email proofs for review over. The high res images that are created of the proofs has been really helpful to pass along.

What do you dislike about Litmus?

The insights could be a little more helpful. It would be great to be more explicit when your email may be falling into a spam trap.

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

Email proofs - updating templates, submitting proofs for review internally for approval.

"Litmus is very easy to use and checks against all possible email clients so you save time too"
What do you like best about Litmus?

Litmus is very easy to use and checks against all possible email clients so you save time by not having to go to each one individually. I also like that it integrates with SalesForce so I can do the checks directly there instead of having to toggle between the two platforms.

What do you dislike about Litmus?

Nothing that I can think of at the moment

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

Making sure our emails work across all email clients and views for consistency.

"Great tool to review for all different email clients"
What do you like best about Litmus?

I can keep using the same share URL and send multiple new tests to that URL instead of constantly making a new one for each new test for the same email.

What do you dislike about Litmus?

Sometimes I can't see certain email clients because they don't load properly, and I have to resend the email.

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

The ability to test emails to make sure they're all consistent before they get sent to the client.
