The testing tools
This is how most people find MailViewr, and it stays open. These tools will not move behind a paywall when paid plans launch.
- HTML & MJML email preview across every client we test
- Code editor with live preview
- Dark-mode testing with each client's real algorithm
- Accessibility checker — 43 axe-core rules + 6 email-specific, no signup, no cap
- MJML → HTML compiler and online MJML editor
Free — early access
The Email Builder
The drag-and-drop builder and the full Email Readiness suite are free at today's limits while the builder is in early access. Paid plans are coming — see below.
- Drag-and-drop Email Builder
- Full Email Readiness score — spam, QA, compatibility, accessibility
- SpamAssassin scoring with a per-rule breakdown
- Asset uploads, template library, snapshot history
- Shareable preview links and downloadable PDF QA reports
What's coming
Paid plans are coming. Hear it first.
When paid plans launch, the waitlist gets told before the site changes — and gets a launch offer for being early. Joining doesn't change anything about your account today.
Paid plans are how MailViewr stays alive and keeps the free tools free. There's one person building this.
