Email testing platform for QA and CI release gates

MailSlurp email testing gives teams real inboxes and test-friendly APIs so they can verify full message journeys before production.

Choose your starting path

Path 1: Pre-release confidence (quick start)

Start with Email Sandbox if your immediate goal is safe message capture and fast debugging.

Path 2: CI release gates (engineering teams)

Start with Email integration testing if your team needs deterministic wait/assert flows in automated pipelines.

Path 3: Rendering and quality checks (template-heavy teams)

Add Email compatibility testing when you need client-rendering and content-quality validation.

What to validate on every release

Message delivery to the correct recipient.
Links, codes, and call-to-action destinations.
Subject and body correctness (text and HTML).
Attachment and MIME behavior.
Event/webhook behavior for asynchronous processing.

Typical implementation stack

Provision inboxes from API.
Trigger application workflow.
Wait for matching message.
Extract links/codes/content.
Assert expected behavior.
Fail build on mismatch or timeout.

Extend beyond basic pass/fail checks

Once base assertions are stable, most teams add operational controls so failures are easier to triage and route:

Messaging webhooks for event-driven ingestion and replay-safe debugging.
Team mailboxes for shared ownership across QA, support, and release teams.
Email auto-reply for policy acknowledgements and escalation handoffs.

FAQ

Is this only for end-to-end browser tests?

Teams use API tests, unit and integration tests, contract checks, and browser tests together. MailSlurp gives each of those layers the same message evidence model.

Can non-engineers review test messages?

Yes. QA and product teams can inspect inboxes in dashboard workflows while engineering keeps tests in code.
