# Litmus review (2026): is it worth it? > Email preview, testing and monitoring across 100+ email clients Checked Nov 12, 2026 ยท graded Nov 13, 2026 by ToolGPA. 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. - **Category:** Email Marketing & Newsletters - **Made by:** Litmus Software, Inc. - **Website:** https://www.litmus.com - **Runs on:** Web - **Who should skip it:** Skip it if you want one tool that also sends your campaigns, because Litmus doesn't. - **Facts last checked:** Nov 12, 2026 ## Pricing Litmus's current pricing could not be confirmed from its own site. ## Key features - **Email previews:** Preview an email in desktop, mobile and web email clients, including dark-mode versions of many of them. - **Email building:** Build on-brand templates so teams can assemble emails quickly, with testing alongside. - **Live monitoring:** Alerts on problems with deployed emails, such as failing links and broken rendering after a client update. - **Review and approval:** A central place for collecting feedback and sign-off on an email before it goes out. - **Personalization:** Add content such as live polls, personalized images and countdown timers to emails. - **Deliverability:** Inbox placement, domain reputation and engagement insights, presented as part of Validity Engage. ## Good for - Email teams that need to check rendering across many clients before sending - Groups that route every email through a review and approval step - Marketers who already have an email service provider ## 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. ## ToolGPA grades **GPA: 1.6 out of 4**, graded Nov 13, 2026. 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. - **Value for money: C.** Nothing 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. - **Free plan and trial: F.** No free plan and no trial on the listing. The Pricing link goes to a contact-sales form. - **Features: D.** Previews, 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. - **Ease of use: C.** No 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. - **Platforms and integrations: B.** Web only, but it ties into Mailchimp, Klaviyo, HubSpot, Campaign Monitor, Salesforce Marketing Cloud, Marketo, Eloqua and Responsys. These are ToolGPA's own grades. Graded from this listing, whose facts were read from Litmus's own pages on 12 November 2026.

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: 91 of the 102 other email marketing and newsletter tools grade higher. - You could make: Templates and reports: an app builder makes these well. - You could not: It plugs into other products, Mailchimp, Klaviyo and HubSpot among them. A judgement by ToolGPA from this listing, by rules that are the same for every tool. Nothing was built to test it. ## Works with Mailchimp, Klaviyo, HubSpot, Campaign Monitor, Salesforce Marketing Cloud, Adobe Marketo, Oracle Eloqua, Oracle Responsys **Tags:** Templates, Reports ## Alternatives - [Mailchimp](https://toolgpa.com/tools/mailchimp): Email and SMS marketing with automations, priced by contact count.
