Don't trust them / my experience **Rating:** 0.0/5.0 stars **Reviewed by:** Evan K. | Founder/CEO, Small-Business (50 or fewer emp.) **Reviewed Date:** May 13, 2026 **What do you like best about Litmus?** Nothing, they dropped the package I liked **What do you dislike about Litmus?** They dropped their self-service package with only 1 month's warning and no migration path except for to upgrade to their (unaffordable) enterprise package. I also didn't even realize they did this because they sent the email from their marketing domain, which I have under my email filters (rich, for an email company!) Do not trust these guys. Support is just an AI robot that tells you to buy the enterprise package. Absolute joke. **What problems is Litmus solving and how is that benefiting you?** Nothing now. We used it to test email designs ### 2. Litmus Boosts Email Marketing Precision and Efficiency **Rating:** 5.0/5.0 stars **Reviewed by:** Grecia L. | Email Marketing & Marketing Automation Specialist , Mid-Market (51-1000 emp.) **Reviewed Date:** October 16, 2025 **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. **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. **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. **Official Response from Danielle Contin:** > Hi Grecia, Thank you so much for sharing such a detailed and thoughtful review!

Collaboration Made Easy, Minor Pin Issue Aside **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Enterprise (> 1000 emp.) **Reviewed Date:** November 03, 2025 **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. **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. **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. **Official Response from Danielle Contin:** > 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! ### 4. Great for Email Testing, but Pricing Could Be Friendlier **Rating:** 2.5/5.0 stars **Reviewed by:** Verified User in Internet | Mid-Market (51-1000 emp.) **Reviewed Date:** October 03, 2025 **What do you like best about Litmus?** Litmus is an incredibly powerful tool for anyone working in email marketing. I really like how it allows me to preview emails across dozens of devices and email clients before sending. The design insights and spam testing features save a lot of time and reduce the risk of errors. The analytics are also very useful, especially when tracking engagement and performance at a granular level. **What do you dislike about Litmus?** The main drawback is the price — it can be quite expensive, especially for small teams or businesses. Some features feel like they should be included in the lower-tier plans but are only available at higher price points. The interface, while clean, could also be a bit faster when switching between previews. **What problems is Litmus solving and how is that benefiting you?** Litmus helps me ensure that every email campaign looks perfect across different devices and inboxes. It reduces the risk of broken designs, formatting issues, or emails landing in spam. This gives me more confidence in the campaigns I send and improves overall deliverability and engagement. ### 5. Makes QAing Emails so Easy! **Rating:** 5.0/5.0 stars **Reviewed by:** Kelsey M. | Email Marketing Coordinator, Mid-Market (51-1000 emp.) **Reviewed Date:** February 25, 2025 **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! **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. **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! **Official Response from Becca Gage:** > Hi Kelsey, Thank you for sharing your experience with Litmus! I'm sorry to hear you've had some issues with the code not updating, we completely understand how that would be frustrating. If you are still experiencing this issue, please feel free to reach out to our support team at hello@litmus.com, they are always here to help.

I highly recommend it to anyone in the field. **What do you dislike about Litmus?** As a proofer, the main challenge I've encountered is the difficulty in collapsing and searching through archives and folders. This process significantly slows down the computer and hampers overall efficiency. **What problems is Litmus solving and how is that benefiting you?** As an email proofer, Litmus is a game-changer. It makes sure emails look great on all devices and speeds up testing with handy previews and analytics. They're always updating with cool new features, and the community is super helpful.

Easy plug and play testing with your defined selection of email clients to test **Rating:** 5.0/5.0 stars **Reviewed by:** John S. | Digital Platform Engagement Analyst, Enterprise (> 1000 emp.) **Reviewed Date:** July 01, 2025 **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. **What do you dislike about Litmus?** There is no automatic email folder sorting. So it can just become a big running list. **What problems is Litmus solving and how is that benefiting you?** Litmus enables us to confidently send out all our marketing campaigns by allowing us to visually-check individual emails before we send them out. ### 8. Email template development and testing **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Computer Software | Mid-Market (51-1000 emp.) **Reviewed Date:** June 10, 2025 **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. **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. **What problems is Litmus solving and how is that benefiting you?** Litmus is majorly solving the issue to test mail templates in various devices by instead offering all device previews in one place. Also it helps in solving the problem of hosting assets we use in our email templates as litmus does that for us. ### 9. Litmus - an industry verb **Rating:** 5.0/5.0 stars **Reviewed by:** Kirk K. | Email Specialist, Enterprise (> 1000 emp.) **Reviewed Date:** March 19, 2025 **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. **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. **What problems is Litmus solving and how is that benefiting you?** Consistency across browsers and the cause of hair loss de jour Dark Mode. **Official Response from Becca Gage:** > Hi Kirk, Thank you for being a long-time user of Litmus! We're glad to hear that you find our platform to be the best for testing!
