Developers: build on real mail infrastructure

The best email integrations are boring: predictable auth, clear errors, webhooks, and dashboards that match production reality.

At a glance

Plain-language summary for buyers, operators, and search engines.

In simple terms

Developers integrate email by API/SMTP and need state + events, not a black box.

Why it matters

Email bugs are high severity; you need traceability and controls.

How CloudJet handles it

Use CloudJet’s API/SMTP model alongside routing and monitoring for complete lifecycle coverage.

Integrate once, operate with confidence

API, SMTP, and webhooks with routing and monitoring that match how you ship product mail.

API + webhooks

POST /v1/send
{ to, subject, template_id, tags }
deliveredevt_8f2a…
openedevt_9c1b…
bouncedevt_2d4e…

Predictable auth

Clear errors and stable endpoints for production.

Event streams

Webhooks for delivery, bounces, and complaints.

Staging lanes

Keep sandbox sends off production reputation.

What to integrate first

01

Domain verification, sending endpoints, and webhook destinations for operational events.

02

Keep staging isolated from production sending lanes.

Production integration patterns

01

Use idempotent send keys, structured tags per tenant, and webhook retries with signature verification.

02

Surface delivery failures in your own observability stack—not only in a mail vendor UI.
