What it does

Automate email and SMS tests, like account verification and password resets, using any language or testing framework using the Mailosaur API. Stop email being delivered to customers using fake SMTP servers.

Instant, secure inboxes, test numbers, and email previews to test every sign-up, password reset, and authentication flow automatically.

Test email and SMS end to end, with real‑device previews built in. Validate critical user flows like sign‑ups and authentication using secure inboxes, dedicated numbers, and accurate previews. Verify every message before it hits an inbox - check content, layout, links, and flows end-to-end. Test OTPs, MFA codes, and transactional messages with dedicated numbers and secure delivery. See how your emails render across clients, devices and dark mode, with previews integrated into your email tests. Mailosaur gives your team a dedicated, scalable environment for stress-free message testing and email previews your whole team can rely on.
