# QA and release teams

QA teams use MailSlurp to validate end-to-end flows with real inboxes and phone numbers instead of mocks. Release teams use it to prove delivery, rendering, and message quality before launch.

Start here:

- [Integration testing guide](/docs/testing/)
- [Wait for methods](/docs/wait-for/)
- [Device previews](/docs/device-renders/)
- [Email audit](/docs/email-audit/)

Then add:

- [Deliverability tests](/docs/deliverability-test/) for broader pass/fail release gates
- [Campaign Probe](/docs/campaign-probe/) for live-campaign capture and review
- [MFA/TOTP devices](/docs/totp/) for deep authentication testing

If you want broader product docs, continue with [Features](/docs/features/) or [Guides](/docs/guides/).
