Don’t just take our word for it—see how Litmus performs in the hands of real users.
“Makes QAing emails so easy!”
I used to check emails manually across devices. With Litmus, I save hours. Clients can comment directly in the email, and spam testing is seamless.
Kelsey M., Email Marketing Coordinator, Mid-Market (G2.com)
“Amazing way to stay ahead of the game!”
Litmus is intuitive and visually appealing. Previews, analytics, and testing tools have improved my workflow. I love the webinars and user community.
Melissa F., Senior Consultant, Enterprise (G2.com)
“Easy plug-and-play testing”
I can visually QA all email clients at once. It’s fast and efficient. I just wish there was automatic folder sorting—it gets cluttered.
John S., Engagement Analyst, Enterprise (G2.com)
“Fantastic visuals to get the campaign right”
The platform is easy to use and gives you a clear view of how your email will render. But removing the free basic account made it hard to justify the cost.
Ryan M., Director, Design (Capterra)
“Must-have for email insights and deliverability”
Even if you’re new to email platforms, Litmus is easy to use. It’s essential for previews and inbox performance.
Eleni Y., Marketing Director, Self-employed (Capterra)
“Very unhappy with their billing”
They charge per preview, not per email. Even basic QA tests exceed limits, and they block your account unless you pay more. I’m quitting this scam.
Mikhail A., Verified Reviewer (Trustpilot)
“Predatory business model”
I forgot to cancel after the trial and paid $99/month for four months without using it. They refunded only one month. It’s exploitative.
Mads N., Verified Reviewer (Trustpilot)
