Litmus review (2026): is it worth it?
Email preview, testing and monitoring across 100+ email clients
Black Friday: is there a Litmus sale?
Litmus report card
Weak · out of 4.0 · graded Nov 13, 2026
Best for checking how an email looks in 100+ inboxes before it sends
Litmus shows you how a marketing email will look in a long list of email apps, then watches it after it goes out. But it doesn't send anything, so you still need an email platform on top, and there's no price on the site at all, only a contact-sales form.
Who Litmus is for
- Fits if your team already sends from an email platform and needs to check rendering before every send
- Works for groups that put every email through a review and sign-off step
Who Litmus is not for
- Skip it if you want one tool that also sends your campaigns, because Litmus doesn't
- Not for you if you need a price before talking to anyone: the site only offers a sales form
- Watch out: the site now calls it part of Validity Engage, so product names and packaging may differ from older material
- Too light for a one-person newsletter, since it's built around teams checking and approving emails
Why Litmus gets a 1.6
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- CValue for moneyNothing is published, so there's no price to set against what email tools charge (middle of the category: $15 a month). That puts it in the ordinary slot until a quote says otherwise.
- FFree plan and trialNo free plan and no trial on the listing. The Pricing link goes to a contact-sales form.
- DFeaturesPreviews, monitoring, review and approval, but it doesn't send campaigns. It works beside Mailchimp, Klaviyo or HubSpot, so on its own it can't do the email job.
- CEase of useNo rating on record. It's a web app that you connect to your email platform, so there's some setting up before the first preview.
- BPlatforms and integrationsWeb only, but it ties into Mailchimp, Klaviyo, HubSpot, Campaign Monitor, Salesforce Marketing Cloud, Marketo, Eloqua and Responsys.

Keep Litmus, or make your own?
Keep it
The plain part of Litmus you could make: templates and reports. What surrounds it you could not. The 1 things listed below take a company, not a weekend.
That makes this kind of software worth paying for, not this one in particular: 56 of the 57 other email marketing and newsletter tools grade higher.
What you could make
- Templates and reports: an app builder makes these well.
What you could not
- It plugs into other products, Mailchimp, Klaviyo and HubSpot among them.
What this rests on. Litmus’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is Litmus?
Litmus is a platform for checking, building and reviewing marketing emails before and after they send. It previews messages in a long list of email clients and devices, monitors deployed emails and gathers feedback and approvals. It sits alongside an email service provider rather than sending campaigns itself, and it is now presented as part of Validity Engage.
Worth knowing
- Prices are not published: the Pricing link leads to a contact-sales form.
- Litmus does not send campaigns; it works with an email service provider such as Mailchimp, Klaviyo or HubSpot.
- The site now describes Litmus as part of Validity Engage, so product names and packaging may differ from older material.
