"Litmus - A Complete package and A Great Software for Email Testing"
What do you like best about Litmus?

As one of our most important channels is email marketing, Litmus has proven beneficial. Litmus offers effective email marketing solutions that support in creating campaigns, proofreading, detecting spam, and other areas. It has great features that can be integrated with many email marketing tools that show how an email renders on different platforms and devices. It contains a sufficient number of browsers to test rendering issues and it is very easy to use which leads to the high frequency of use. They have the best email design guides in the industry which can help users to implement the testing easily. Amazing customer support when integrating with other tools.

What do you dislike about Litmus?

We need to utilize a different server because Litmus lacks an image hosting server.

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

Email testing is the most irritating and time-consuming part of email marketing. Emails are rendered differently in different clients, ESPs, browsers, mobiles, tablets, and applications. While testing we need to use different browsers, devices, and clients to check the rendering part. But litmus shows all clients, browsers, and devices in single page.

"Awesome for email building and testing"
What do you like best about Litmus?

I love that Litmus offers previews to see how your email code renders in various devices and email clients. This has been a very helpful tool as our team has tested dark mode renderings!

What do you dislike about Litmus?

Overall, I do feel like Litmus builder does have some limitations, but it's really not a setback for our team. We do a lot of our coding in MJML and then bring them into Litmus for templating. Builders often add a bit of bloated code, so we are just cautious of how/where we use those elements in our emails.

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

Specifically, we love the Email Testing capabilities and seeing how our emails will render in the different clients. This is extremely helpful for us!

"Litmus: Essential for QA and peace of mind"
What do you like best about Litmus?

The fast, easy, and intitive user interface which allows us to test out our emails and view it on multiple platforms, devices, and browers. Any questions we've had have been quickly answered by the responsive customer support team.

What do you dislike about Litmus?

I have yet to experience a downside of Litmus or any difficulty.

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

By being able to test our emails across multiple browsers, devices, and platforms we're able to see how the email layout appears - which is crucial to our nonprofits's fundraising efforts.

"It just works - and fantastic support"
What do you like best about Litmus?

For its core competencies - Litmus really just works. The renders are accurate. The editor has nice quality of life features that make it pleasant to work in. All of that little stuff really adds up and makes it such a nice platform to work in. The other huge thing is that the support and CS experience are so much better than most other B2B products I have the displeasure of using. The litmus team are proactive, and you can tell that the whole suite was basically developed by people who have jobs like I do. It's not my money being spent, but I'd fight pretty hard to keep Litmus in our stack at this point.

What do you dislike about Litmus?

It's really a nitpick, but our implementation of Marketo utilizes Marketo workspaces, and that breaks the ability to use their slick integration. We therefore have to send in our emails manually to proof, which is annoying but not a dealbreaker for our use case.

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

We primarly use Litmus for the renders of different email clients. This really does just work. The renders are accurate and it saves me SO MUCH TIME. We do also use the proofing and builder features to a lesser extent and these are great too.

"Litmus has saved me a lot of headaches when testing emails"
What do you like best about Litmus?

The preview option for various email clients. Outlook is a nightmare to design for and each version of Outlook has different issues, so seeing those before my clients do (we're a Gmail shop - so we're blind to them otherwise) is clutch.

What do you dislike about Litmus?

The process of using the spam check is a little arduous, but the results make it worthwhile.

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

Outlook is notoriously difficult to get email renders to look the same as every other client, and with so many versions of Outlook to design for, it can be very difficult to check them all without a tool like Litmus.

"Good experience so far"
What do you like best about Litmus?

It was very convenient and easy to test out curated emails and newsletters, to make sure that they work. We could easily check out the email clients that didn't work, and rectify the issue quickly.

What do you dislike about Litmus?

There was a 2FA tied to a phone number. When one of our team member left, it meant switching the phone number to another one. I wish phone number wasn't part of the 2FA, considering that it was used by a team.

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

Making sure that emails are presented correctly across all email clients and browsers.

"Email QA made easy!"
What do you like best about Litmus?

Emails will never render the same on every device and its a drag trying to design an email and anticipate it to look the same across the board. Litmus allows me to preview how my email will render on a variety of devices, and easily generate previews. On top of that the litmus tracking code allowed me to understand what devices most of my subscribers are viewing on so I know which designs to implement!

What do you dislike about Litmus?

The limits on previews based on subscription tier!

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

Spam triggers, Email QA, subscriber tracking.

"Of the email preview tools, Litmus is by far the best."
What do you like best about Litmus?

The platform has been very helpful, particularly with regards to our email campaigns that I use Litmus on mainly. It provides perfect previews, so I may see how they will look in different clients. Therefore, this is crucial in our strategy as it ensures optimal design for every email client. In addition, Litmus’ recommendations help us improve the campaign plan. In general, it’s an excellent base for emails related work.

What do you dislike about Litmus?

Although the platform works nicely for email marketing, the subject line and preview header testing should be better. Additionally, I thought it slightly expensive as compared with other optimisation procedures that I have ever encountered.

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

Litmus assists in detecting as well as correcting design discrepancies among various email clients. This allows for clarity in the organization’s messaging by making sure that our email content appears professional and uniform. This, finally, helps us to keep an ongoing, fruitful dialogue with our customers.

"It answers questions for me I didn’t know that I had"
What do you like best about Litmus?

Once you get your account setup for testing and previews, it becomes an important part of my workflow for new email campaigns. It also has taught me a lot about email design because of what I know is possible, not possible, or only possible in certain email clients. I would not have been able to keep my job that I currently have if I didn't use litmus.

What do you dislike about Litmus?

As I'm doing many iterations of the same email. I wish I could just test on certain mail clients in a quick way rather than the same amount each time. This might be possible but not with my current privileges on my account.

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

It helps me to create reliable emails for my current customers. It helps me to know that when I send an email out. I can feel confident it's not going to look all jacked up to CEOs, especially those using outlook

"Basic email tool - must have."
What do you like best about Litmus?

I love the innovation they are applying to the product currently, bringing it in line with recent "must-haves" in email marketing tools and technologies.

What do you dislike about Litmus?

The price. The enterprise version of Litmus is not worth the investment. They are a bit late to the party as several high-end ESP and CRM services do have many of the tools they offer built into their systems already.

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

The primary purpose of litmus in our team is that it's a collaborative space for more junior members of my team to build and then test HTML emails before they go into the execution phase. It's easy to use does not come with a high learning curve and email code can be consistent and properly vetted before deployment.

What do you like best about Litmus?

I absolutely love the ability to see how my email will render in multiple inboxes at any time through the Chrome extension. It's easy to use and I can test new elements as I go.

What do you dislike about Litmus?

Sometimes the Chrome extension crashes or can't keep up with my changes. I feel that the testing results on the image alt links don't always show correctly either

"Long time Litmus user"
What do you like best about Litmus?

Litmus has tools to help with all aspects of the campaign process. Proof for collaboration, Checklist for testing, Analytics for read time data, and builder for creation. Litmus adds value to all setups in your campaign process.

What do you dislike about Litmus?

Previews & QA offers a very detailed set of test but only email client previews are available in a chrome extension or in app integrations (like in Salesforce Marketing Cloud). The extension and integrations offer a quick way for email client rendering but is missing the load time, accessibility, spam checking that the Previews & QA offer within the Litmus platform.

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

Read time data, email client rendering, and collaboration with my team on campaign content that is accessible to team Members outside of the marketing team with direct Litmus access.

"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.

"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.

"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.

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.

"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.
