"Best-in-class email testing"
What do you like best about Litmus?

The best-in-class for email testing. Its pre-test sending is invaluable for making sure emails look right on every mail client. Pricing is reasonable. Its content and resources are really helpful too.

What do you dislike about Litmus?

I doesn't take all the pain away from sending a bulk campaign. A Grammarly style spelling and content checker would be really useful.

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

Making sure our emails look faultless on every mail client.

"Must have for Email Marketers"
What do you like best about Litmus?

The best parts are the email previews, so you can see what your email looks like in every inbox. This helps you catch errant code and make sure every user has an optimal experience. You can also put emails in the builder tool to easily tweak and recheck code. They also have super helpful blogs/newsletters.

What do you dislike about Litmus?

It's not a cheap tool, so the barrier to entry is high. So you need to be running a big/robust program to make it worth it. It can also be overwhelming to jump into and understand the full extent of its capabilities.

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

It's a QA tool to ensure our clients get the best content possible and their customers get the best experience. Even for those who feel highly versed in email best practices, it's a good gut check to make sure nothing gets missed in the production and sending process.

"Easily check how your campaign will look like"
What do you like best about Litmus?

In place of sending the email to different emails and check them on different devices and browsers, you just need to check it with Litmus.

What do you dislike about Litmus?

They need to have more integrations with other platforms to allow easily check the emails despite the service you want to use to send them.

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

We do email look checking before sending them to our users and prospects.

"Excellent UI / UX"
What do you like best about Litmus?

The ease of use is fantastic. It provides all of the features you need at an amazing price point.

What do you dislike about Litmus?

Nothing within their control. I'd like true email heatmapping capabilities, but that's not currently possible regardless of the platform.

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

We started using it for email functionality testing. We've realized that we can expand to more advanced email analytics (beyond our email marketing platform).

"Effective email tool"
What do you like best about Litmus?

It is helpful to see the different variations of emails in different email providers. I like being able to go in and edit the code and see how it changes the email/select the different sections.

What do you dislike about Litmus?

Sometimes more recent updates to email providers aren't shown immediately. I also wish there were more ways to diagnose what is wrong with an email within the tool.

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

We can easily see what our emails look like in various email platforms.

"Essential tool in email marketing and collaboration"
What do you like best about Litmus?

The easily shareable testing links are helpful in large-scale email marketing. Litmus has a huge variety of client previews, which helps cover all bases.

What do you dislike about Litmus?

The number of decisions on what client previews to include can be overwhelming for new team members. Having more pre-built set ups would help with this.

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

Litmus helps us quality control the emails we send out. It removes a huge amount of manual testing by providing all email clients in one place.

"Litmus helps us with email testing for our customers."
What do you like best about Litmus?

Zip-Download of the previews. Retesting emails that failed our tests.

What do you dislike about Litmus?

- no API available (plan: litmus plus) - would love to download the zip automatically in our own system - can't choose between different email client lists (email on acid has this feature) - can't sync/share email client lists between team members - can't easily test email for just one client or two clients (mostly outlook win) --> need to change client list twice (email on acid has better options) - previews on the page are slow (detail page)

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

- testing emails for our clients for all kind of email clients

Oriented on developers more than on users (though users can definitely find some added value too)

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

It helps me to ensure that the mailings look good when ending in the inbox of different email providers

Allows us to view our communications on a wide range of devices and clients to see where we need to make updates. The email analyzer is very helpful as well.

There are certain times where the SFMC connector will not work and we will be required to log out of SFMC and back in for it to properly connect to Litmus.

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

Quicker email communication QA time which allows us to get to market quicker with our communications.

"Effective email review toolset."
What do you like best about Litmus?

Email preview tools are best in class. It's an essential part of our MarTech stack.

We still miss the website preview tool. The use case is now so specific, we wish it could be utilized in other ways.

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

We send a ton of emails on behalf of our clients. This cuts our QA time way down.
