Mailtester.ai

Check newsletter deliverability and get prioritized suggestions before sending

Meet Mailtester.ai

Mailtester.ai analyzes newsletter messages before they go to subscribers. A sender forwards a test email to a temporary address, then receives a score, an estimated inbox placement, and suggested changes. The analysis considers the subject, message content, links, and authentication signals, with forecasts for Gmail, Outlook, and Yahoo.

Reports distinguish between primary inbox, promotional, and spam placement rather than checking whether subscriber addresses exist. Paid AI analysis can suggest revisions to the subject, body, and call to action. The service works with tools that can send a test message, making it useful for newsletter writers and marketers reviewing a campaign before distribution.
