Transactional email HTTP API and event webhooks

Official documentation (opens in a new tab)

Overview

Mailgun sends transactional email with straightforward HTTP APIs - ConnectSoft integrates Mailgun when clients prefer it over SendGrid or ACS Email for domain reputation control.

We configure domains, DKIM, and event webhooks that update user profiles on bounces, complaints, and unsubscribes.

Batch sending and template variables are typed in code - reducing production surprises from ad-hoc HTML.

Mailgun coexists with marketing providers - Mailchimp, Braze - for clear separation of transactional versus campaign mail.

Why we integrate it:

  • Domain verification and DKIM/DMARC checklist
  • Event webhook signature validation
  • Template variables documented per message type
  • Suppression lists synced to product database
  • EU versus US region selection documented
  • Monitoring on delivery rates and API latency
