Turn every transactional email into a reliable assertion.
Mailvator TestLab gives Playwright, Cypress and CI pipelines isolated inboxes, structured messages, extracted OTPs and signed delivery events.
Deterministic addresses
Create an address per test run so parallel suites do not share state.
Fast polling
Wait for a matching sender or subject and receive structured JSON.
Least-privilege keys
Issue read-only or inbox-creation credentials to each CI environment.
Webhook retries
Receive HMAC-signed events with durable retry history.
