Summary
Emailens previews how HTML email content renders across 21 email clients and checks compatibility across 298 CSS and HTML features. It gives a compatibility score from 0 to 100 per client, along with rendered screenshots and simulated dark mode versions. Users can submit HTML, React Email JSX, MJML, or Maizzle. Available tools include a web app, REST API, MCP server, GitHub Action, and standalone engine package. Emailens can import campaign HTML from a view-in-browser link; Mailchimp URL import is marked verified, while other listed platforms require pasted HTML. It also covers merge tags for Mailchimp, Klaviyo, HubSpot, Braze, and Salesforce Marketing Cloud. The free plan includes 30 simulated previews per day across all 21 clients and a seven-day audit history. Paid plans begin at 9.00 USD per month. Emailens says unsaved previews are processed in memory and authenticated previews and screenshots are automatically purged after 30 days. It states that connections use TLS 1.3 and databases and object storage use AES-256 encryption at rest.
