Here is a breakdown of what MailerSend offers:

The Webhook Firehose

For debugging, webhooks are essential. MailerSend provides granular webhook events:

The key innovation here is webhook retries with exponential backoff. If your server fails to acknowledge a webhook (HTTP 200), MailerSend retries for up to 72 hours. They also provide a "Delivery Log" UI that visualizes exactly where an email died—a lifesaver for support tickets.


Cons / considerations

3. Inbound Email Parsing (Inbound Routing)

Need to allow replies to transactional emails? MailerSend’s Inbound Routing converts incoming emails into HTTP POST requests to your server. This is perfect for helpdesk integrations or allowing customers to reply to receipts with questions.

Integration basics (example flow)

  1. Create a MailerSend project and API token.
  2. Add sending domains and configure DNS (SPF/DKIM) for better deliverability.
  3. Build or upload templates in the dashboard, using template variables for personalization.
  4. Call the Messages API with recipient, template ID or HTML, variables, and optional attachments.
  5. Handle webhook events for bounces, complaints, and delivery updates to maintain list health.

Pricing & support

MailerSend offers a free tier with limited monthly sends and paid tiers that scale with volume and features. Support is available via documentation, community resources, and paid support for higher plans.

Suppression and Validation

The single biggest cause of poor deliverability is sending to invalid addresses. MailerSend integrates a real-time email validation API. You can ping their endpoint before you add a user to your database. If the email is a typo (gmai.con) or a known spam trap, the API returns a 400 error, saving you from a bounce.

Furthermore, their suppression list is automatic. Hard bounces are immediately blocked from future sends. This isn't revolutionary, but the speed of suppression is. Within 200ms of an ISP returning a "550 No such user," MailerSend has updated its blocklist.
