Our verdict on Emailens

Emailens is an email quality-assurance tool for developers and email teams that need to review HTML emails before delivery. It previews messages across 21 email clients, reports CSS compatibility, simulates dark mode, and provides client-specific fix suggestions. The product also checks spam signals, links, accessibility, images, email size, and inbox-related content. It accepts HTML, React Email JSX, MJML, and Maizzle templates, with web, API, and Chrome extension access.

Pricing is straightforward for teams starting small. The Free plan costs $0 per month and includes all 21 email clients, a CSS compatibility report, dark mode preview, DNS checks, and an MCP server. The Dev plan costs $9 per month or $90 per year, adding full API access, share links, Visual Diff, MCP screenshots and sharing, AI Fix, and CLI access. The Pro plan costs $19 per month or $180 per year and adds a pre-send gate, CI/CD integration, a GitHub Action, unlimited simulated previews, full API access, AI Fix, and AI Builder.

Emailens fits workflows that need both visual review and automated checks. Its integrations include Claude Desktop, Claude Code, Cursor, GitHub Actions, Figma, Mailchimp, Klaviyo, HubSpot, Braze, and Salesforce Marketing Cloud. The product supports AI email generation, compatibility repair, and Figma-to-email HTML conversion, while its open-source compatibility engine adds another integration path. Choose Emailens for affordable, developer-oriented QA with accessibility, spam, link, and automation features. Teams requiring coverage beyond 21 email clients or Pro-only delivery gates should consider a broader or more advanced alternative.
