"Litmus Boosts Email Marketing Precision and Efficiency"

5/5

What do you like best about Litmus?

Litmus has become an essential tool in my email marketing workflow. What I appreciate most is how it removes the guesswork from email testing, allowing me to preview exactly how my campaigns will appear across all devices and inboxes before hitting send. The platform’s comprehensive preview capabilities and in-depth troubleshooting tools give me confidence that my emails will render perfectly and avoid spam filters, which is crucial for maintaining high engagement rates. Beyond just visual accuracy, Litmus helps safeguard my brand’s reputation by ensuring deliverability and consistent performance. For any professional serious about email marketing precision, Litmus is a reliable, powerful solution that truly elevates the quality and effectiveness of every campaign. Review collected by and hosted on G2.com.

What do you dislike about Litmus?

One aspect that could be enhanced is the reporting functionality. Simplifying these features would make them more intuitive and allow for easier customization to suit the varying needs of different teams. Additionally, enabling quicker integration with a broader selection of marketing platforms would help streamline workflows even more. Review collected by and hosted on G2.com.

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

Litmus solves the challenge of unpredictable email rendering and deliverability by offering a powerful set of testing tools and detailed analytics. It lets me preview how emails will look on different devices and email clients, which helps catch any design or technical issues before sending. This way, I can fix problems like broken links, missing images, or coding errors early on. By doing this, Litmus helps reduce the chance of emails ending up in spam or not displaying properly. That means more people actually see the emails as intended, leading to higher open and click rates. Overall, using Litmus improves the user experience and helps get a better return on investment from email campaigns by making them more effective and reliable.

"Collaboration Made Easy, Minor Pin Issue Aside"

4/5

What do you like best about Litmus?

I appreciate that Litmus allows me to share email content with people who may not have a Litmus license. I also value the feature that lets me highlight specific areas and indicate exactly where I suggest making edits within the content. Review collected by and hosted on G2.com.

What do you dislike about Litmus?

This is a minor issue, but I would prefer if a pin or comment could stay attached to the specific item it refers to. For instance, when commenting on an image, if the creator moves that image, the pin currently stays in its original position rather than moving with the image. I’m not sure if it’s technically possible to change this, but it’s a small concern compared to everything else Litmus provides. Review collected by and hosted on G2.com.

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

Litmus has made collaborating with others incredibly easy. Before we started using Litmus, our team relied on countless emails, which often led to confusion and messages getting crossed. Now, with Litmus, our workflow is much smoother. I would be truly disappointed if we ever lost access to this tool. Review collected by and hosted on G2.com.

Thank you for taking the time to share such thoughtful feedback! We’re delighted to hear that Litmus has made collaboration smoother for your team, especially by reducing the confusion that comes with email-based reviews. It’s great to know that features like sharing with non-licensed users and pinpointing suggested edits are making a meaningful difference in your workflow.

We also appreciate you calling out the issue with comment pins not moving when an element is repositioned. While it’s a small detail, feedback like this helps us continue improving the platform in ways that matter to users. We’ve shared your note with our product team for consideration in future enhancements.

Thanks again for your kind words — we’re thrilled to be a valuable part of your process!

"Makes QAing Emails so Easy!"

5/5

What do you like best about Litmus?

Litmus has made my role at work so much easier! It has been a breeze to check emails on all different platforms on one website. I used to have to send emails from the ESP to all different email addresses and check them from my phone, tablet, and desktop. With Litmus, I have saved so much time. I also love the fact that our clients can make corrections directly in the email, letting us know what to change or fix. It's also very easy to send emails directly from the ESP to Litmus to check for spam issues! Review collected by and hosted on G2.com.

What do you dislike about Litmus?

We sometimes have issues where the code doesn't update the changes, but they are seen in the previews. This can be frustrating when there is a tight turnaround on a deadline, and we have to go back and forth between the two previews to see what hasn't been changed. Review collected by and hosted on G2.com.

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

Litmus is solving the problem of checking the emails to make sure they look great across providers and platforms. Before Litmus, we had to do this manually and it just took forever. Litmus has saved me hours of time allowing me to test emails on different providers and platforms directly on Litmus! Review collected by and hosted on G2.com.

"Easy plug and play testing with your defined selection of email clients to test"

5/5

What do you like best about Litmus?

The length view allows you to view all your email client tests at once and zoom your browser in with full resolution. This allows me to eyeball and complete visual design/layout QA within 2 minutes, instead of opening each individual email-client test result to verify. Review collected by and hosted on G2.com.

What do you dislike about Litmus?

There is no automatic email folder sorting. So it can just become a big running list. Review collected by and hosted on G2.com.

"Email template development and testing"

4.5/5

What do you like best about Litmus?

One of the main upsides of using Litmus is the dynamic preview that is updated as and when we code, also the previews from different devices which helps to understand the rendering in various email clients and devices.

Also the Litmus personalize pro which helps build reusable content blocks with ease. Review collected by and hosted on G2.com.

What do you dislike about Litmus?

Some downsides I have faced is the platform is a little slow sometimes and it takes a longer time to load previews and sometimes throws "page not responding" error. Review collected by and hosted on G2.com.

"Litmus - an industry verb"

5/5

What do you like best about Litmus?

I've used Litmus for years. It beats Email on Acid hands down. The Builder feature is intuitive. Overall if you build emails, templates etc you're going to need a platform that shows you how your work looks on a bunch of platforms. Litmus is the best. The ability to quickly share preview sets to stakeholders is great too. Review collected by and hosted on G2.com.

What do you dislike about Litmus?

If it was more intuitive to narrrow down previews to just one or two problem browsers so that I'm not going through the previews quite as quickly would be great, Also the Salesforce plug-in is so limited as to be pointless. But overall, until someone does better, Litmus rules. Review collected by and hosted on G2.com.

Litmus makes email creation easy! From coding highlights to snippets and templates, it's easy to integrate business specific and critical dynamic coding into the platform to use in our system.

"Reliable, quick and easy to use"

5/5

What do you like best about Litmus?

Litmus helps us know as email marketers quickly and efficiently what our emails look like across a wide spectrum of platforms and devices. The renderings are delivered at remarkable speed, and the preview pane is designed for collaboration. I like being able to make notes on the individual renders so that my team can communicate clearly about where the issues might lie. We use Litmus for all of our templates, roughly 2-3 sends daily. Review collected by and hosted on G2.com.

What do you dislike about Litmus?

The only downside is that it can take a lot of time to click through all of the proofs, and I wish that the preview pane tiles could expand with a hover rather than a full slide show. Review collected by and hosted on G2.com.

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

Litmus is helping solve a few problems:

1. How do we create content that renders at time of open

2. How do we test our emails across a wide variety of platforms and devices to make sure that our designs are optimized for all of our audience

3. When we come across a problem, how can we experiment with our HTML coding without inadvertently breaking the design already in our email marketing platform. Review collected by and hosted on G2.com.

"Litmus is My Go To Email Testing Program"

5/5

What do you like best about Litmus?

I love that you can view email previews across all devices - and the program checks to see if your creative is ADA compliant and passes accessibility checks. The platform is easy to use and a great starter platform for both new and experienced email developers. Review collected by and hosted on G2.com.

What do you dislike about Litmus?

There are some render issues in certain previews that litmus creates, the most recent one I can think of is using rounded edges in iPhone previews for CTA buttons will error, and show as blank. Review collected by and hosted on G2.com.

Hi Paige,

We're glad to hear that you find Litmus to be your go-to email testing program! We appreciate your feedback about the email previews and ADA compliance checks.
