MailerSend

API-based email service for transactional and marketing emails.

Capability areas

  • Email activity — retrieve email events (opens, clicks, bounces, deliveries, unsubscribes) for a specific sending domain. Each activity record includes the event type, timestamp, recipient, and message metadata. Requires domain_id to scope results. Paginate with page (cursor) and page_size (default 100).

Workflows

  • Deliverability monitoring: pull activity for a domain to track bounce rates, identify failing recipient addresses, and spot delivery issues.
  • Campaign performance: retrieve activity events after a send to measure open and click rates.
  • Troubleshooting: filter activity for a specific domain to trace whether a transactional email was delivered, opened, or bounced.

Gotchas

  • domain_id required: activity is always scoped to a sending domain. You must know the domain ID before querying.
  • Read-only: the current toolset retrieves email activity only. Sending emails, managing templates, or configuring domains requires additional API endpoints not yet exposed.
  • Pagination: page is a cursor/offset token, not a page number. Pass it from previous responses.
