Our verdict on MailViewr
MailViewr is a web-based email design workspace for marketers and developers who need both visual composition and code control. Users can begin with templates or a blank canvas, arrange reusable drag-and-drop blocks, write or paste HTML and MJML, and compile MJML to HTML in the browser. The product is aimed at solo, small, and mid-market teams that need to export email-ready HTML, inspect client rendering, and run checks before delivery.
The published plans show a free tier with a drag-and-drop builder, comments, reusable blocks, and HTML exports. Plus costs $11 per month and adds unlimited projects, image and asset uploads, Canva import, and priority support. Pro costs $17 per month and adds team workspaces, unlimited sends and exports, and unlimited ESP integration exports. This structure lets a user start without a subscription, then pay for asset handling, collaboration, sending volume, or export capacity as requirements grow.
MailViewr’s standout capability is its pre-send inspection workflow: previews cover Gmail, Outlook, and Apple Mail across desktop and mobile, with dark- and light-mode rendering, accessibility checks, compatibility checks, spam analysis, test emails, and shareable preview links. Integrations include Mailchimp, Brevo, MailerSend, Resend, and Canva, which can fit teams already working in those services. Teams that value inbox-specific QA and mixed visual/code editing should find the feature set well aligned; organizations needing a wider integration ecosystem or a non-web deployment should consider an alternative.
