Four products · zero silos

Everything that sends from your domain, finally in one place.

Most teams glue together an API, a mailbox host, and a marketing tool. MailMarco is all three — sharing one reputation, one contact list, one bill.

Why MailMarco

The boring parts, handled. The important parts, yours.

Deliverability, compliance, and data residency are table stakes we obsess over — so your team can focus on the message, not the machinery.

Deliverability by default

Managed SPF, DKIM & DMARC, warmed pools, and signed VERP return-paths so bounces land where they belong — not in a black hole.

EU / TR data residency

Choose exactly where your contacts and message content live. Regional storage and processing built for GDPR and KVKK.

Unified contact history

One timeline per contact across transactional, mailbox, and marketing email. No more three tools telling three stories.

White-label to the pixel

Your logo, your palette, your domain on every dashboard, email footer, and tracking link. Your clients never see ours.

Built for developers

One POST away from your first send.

A predictable REST API with idempotency keys, webhooks, scheduling, and batch sends — plus a fully typed Node SDK. No SMTP archaeology required.

  • Idempotent sends — safe retries, exactly-once delivery
  • Typed responses & errors, first-class TypeScript
  • Webhooks for delivered, opened, bounced & complained
