Picking between us
- Mailosaur is mature and integrates beautifully with Cypress/Playwright. If you only do test-automation and have the budget, it's great. We're cheaper and our self-host story is real.
- Mailtrap is two products: a sandbox and a delivery service. We're one product that does both, with a real inbound API and HTTP-first ergonomics.
- Mailinator is the simplest fit if you just need throw-away addresses for click-tracking. We add multi-tenancy, audit, and bring-your-own-domain.
