"Best rendering tool"
What do you like best about Litmus?

Litmus has always been my number one choice. It has improved considerably over the past, so we, as Devs/QAs, trust it. The customer support team is also pretty efficient & responds quickly to any technical issues.

What do you dislike about Litmus?

There's always room for improvement since we work in an ever-evolving world, but there's nothing specific.

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

I mainly check how my emails render on various mobile and desktop platforms. It's pretty efficient and result-oriented.

"A full 360 service for building and ensuring deliverability of your communications"
What do you like best about Litmus?

We love Litmus for the ability to see the specific reasons why an email may fail to deliver, from time taken to load an image and accessibility to real world processing into inboxes, tracking each of the main play spam filters. The email building tools are top-notch and really do take the pain out of the building and visualising how your code will render in every email client.

What do you dislike about Litmus?

While not Litmus' fault and because I have to dislike something, it would be advantageous to have more options for integrating mail platforms into the spam tests. Currently, we have to save a CSV of email addresses from Litmus, import them into our system, and send the campaign. Email addresses changing for each spam test, this can become a barrier.

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

Email deliverability scores and improving reputation with first class email builds.

"Collaboration and Testing"
What do you like best about Litmus?

Litmus allows multiple people in my organization to review emails and collect feedback all in one place.

What do you dislike about Litmus?

The one thing I dislike is the need to resubmit the email using a new email, causing the creation of data extensions in my platform. I use HTML paste instead, which seems to work well now that we can update the subject.

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

Litmus allows for collaboration on edits to emails. We are able to ensure our links are working properly and it offers us a tool to share with our content creators what is best practice to avoid spam.
