"HTML decoding 101?"
What do you like best about Litmus?

Litmus has made locating and editing the necessary code sections within emails a smooth process. Instead of needing to scroll through lines of code trying to figure out where the one line of code is that you might guess you need to edit, Litmus takes you right there in seconds. I have found everything very intuitive and easy to use within this app. I consider it a great instructor on where code is and how it functions, and I have learned quite a bit through this app in a short amount of time.

What do you dislike about Litmus?

I haven't found anything to dislike using this app, and I have used it for nearly a year. This has sped up the process with editing HTML emails enormously for me.

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

We need to be able to find sections of code that need to be adjusted to improve email formatting and functionality. We are then able to easily find and troubleshoot those problem sections.

"Super Needed!"
What do you like best about Litmus?

I love that I can see the emails tested on different providers, then can be coded inside the Litmus platform to test how you can fix any errors. It has been helpful.

What do you dislike about Litmus?

I wish there were more analytics for the tracking codes. We use analytics and it's good, but not amazing.

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

Visually seeing how the email sends.

"The ONE must have tool for email marketers and developers"
What do you like best about Litmus?

If you are not render testing your emails then you are not truly concerned about your customers. By using the Litmus tool, you give each customer the experience you intended. As an email developer and professional services Manager, I also appreciate the value of the extra tools built into the Litmus platform. Litmus builds email tools for email geeks and keeps us all on the cutting edge of understanding our craft.

What do you dislike about Litmus?

At times, the renders can take longer to load than my impatience would like.

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

The mystery of email client and device renderings. There is no other way to get visibility into what your customer will see in their Inboxes.

"I love Litmus!"
What do you like best about Litmus?

It allows me to create, edit, test, and proof my many email campaigns -- all in one easy-to-use platform.

What do you dislike about Litmus?

The only thing I have issues with is sorting; it doesn't always work they way it should (clicking on "date" changes the order of emails.)

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

Testing is the biggest thing that it solves for me and my team. And also the "proof" process is a game-changer.

"Litmus - Great Email Testing Tool"
What do you like best about Litmus?

I can see many renderings of emails on device / email client combinations that I otherwise would not be able to test. Getting SPAM filter info and Subject Line evaluations is also very helpful.

What do you dislike about Litmus?

While Litmus has many device / email client combinations to test on, they don't always have the combination a client utilizes. When this occurs, which is not very frequent, it results in rendering issues not being detected until the email "proof" gets sent to the client for review.

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

Litmus helps us to produce and send out emails that look good and represent our clients well across many device / email client combinations. We have an opportunity to resolve many rendering & deliverability issues before leaving the QA stage.

"A go to solution to review emails on multiple email clients"
What do you like best about Litmus?

The Preview Interface is really good, and the fact that you can toggle off images just to see how your email looks without them is pretty great.

What do you dislike about Litmus?

I haven't had a bad experience with Litmus so far, so I don't have anything I dislike.

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

Some customers complain their images do not load in some newsletters they send to different ISPs. We use litmus to check if it's an email client specific issue or a general Issue. Litmus has been pretty accurate thus far.

"I am not an email coder, and it has made it so easy for me to learn email HTML."
What do you like best about Litmus?

I love the snippets. Our lead coder can create them and I can use them, knowing my email will be on brand

What do you dislike about Litmus?

Not much! I like it a lot. Maybe the testing could be faster?? But really it is fast enough.

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

It makes it easy to create emails out of our branded templates. I can design them very quickly and then test them right away. I would day my busness preformabce is better than before.

"The perfect addition to your CRM portfolio!"
What do you like best about Litmus?

Litmus provides the security any email marketer is looking for. With Litmus, you'll see how your email renders across many different platforms, providing ease of mind with your email designs.

What do you dislike about Litmus?

The only downside to Litmus is it can be overwhelming to review all the provided platforms. It's a pretty great problem to have! But I wish there was a smaller list of suggested providers that is easier to manage but still comprehensive!

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

It allows me to test my emails past the platforms I have access to. Plus, it shortens the time it takes to check my email designs! This allows for our team to be smaller and more agile!

"Great and easy to use platform"
What do you like best about Litmus?

Litmus is a must-have tool to review all your emails. It helps with design and testing so you can optimize your email campaigns. You can add comments and check past communications all in a very collaborative way.

What do you dislike about Litmus?

I would love to be able to send actual emails from Litmus and not only stay in the testing environment. When we have a lot of emails to review, we find it difficult to name the versions without affecting the subject line.

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

It really facilitates exchanges between the different stakeholders. It also is a very good library of all our work.
