Does MailerSend verify emails?

MailerSend offers basic email validation through its API, but it does not provide comprehensive list-level verification. Truelist checks every address for deliverability, catch-all status, and risk, giving you a more thorough cleaning.

How do I export recipients from MailerSend?

Navigate to the Recipients section in your MailerSend dashboard, select the list you want to export, and download it as a CSV file.

How often should I verify my MailerSend lists?

For marketing sends, every 3-6 months. For transactional email, verify new recipient addresses at the point of collection using the Truelist API to prevent bounces from the start.

Can I use Truelist with the MailerSend API?

Yes. You can call the Truelist API to verify an email address before passing it to MailerSend's sending API. This is especially useful for transactional flows where you want real-time validation.

Why verify your MailerSend email list

MailerSend charges based on email volume, so every send to an invalid address wastes money and counts against your quota. Transactional emails that bounce also create a poor customer experience. Verifying your recipient lists with Truelist ensures every email you send through MailerSend reaches a real inbox.

savings Reduce Wasted Sends: MailerSend bills by email volume. Verifying recipients upfront means you only spend on emails that can actually be delivered.
shield Protect Domain Reputation: High bounce rates from invalid addresses damage your sending domain. Clean recipient lists keep your reputation intact.
inbox Improve Transactional Delivery: Transactional emails like receipts and password resets must reach the inbox. Verification ensures your critical messages get delivered.
analytics Accurate Delivery Analytics: Invalid addresses skew your delivery and engagement metrics. Verified lists give you reliable data on email performance.
