Email and SMS Test Automation for Engineering Teams
Build software that works, first time
Create and test products that are high quality from the very start.

Focus on building features and functionality, not testing infrastructure
Give everyone on your team their own email server for development. Allow developers to send, capture and analyse emails during development, with their own personal email and SMS sandbox.
Use the same code to capture and test SMS messages, with a single platform that handles all communication testing consistently.
Shield your development and staging environments, by configuring them to send everything to Mailosaur rather than messaging a customer by mistake.
Unlimited email addresses
Use a unique email address for every test, build, team member, environment or any other use case you have. With Mailosaur supporting an unlimited number of email addresses that you can send to from anywhere.
Mailosaur is extremely reliable and offers ease of implementation. The support is thorough, responsive and very personable.
Boost end-to-end test coverage in minutes, by integrating with Mailosaur.
Trigger a process in your product that sends out email or SMS (e.g. requesting a password reset).
Use one of our client libraries to pinpoint and pull the email down into your test code.
Whether it’s checking the content of the message, following a link or using a verification code. Complete the end-to-end process you’re testing.
Write tests with the tools and frameworks you’re already familiar with. With support for all the world’s major testing frameworks, including Cypress, Playwright, Selenium and Robot Framework, and more.
Work in harmony with other teams and departments globally with our centralised system which allows shared access for your entire team on a single account.
With comprehensive Information Security and GDPR-compliant controls, we are committed to protecting your data.
