Build features and functionality,
not testing infrastructure
Mailosaur lets engineering teams get on with development, rather than maintaining custom testing tools
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.
“A lot of user flows on our sites are based around accounts, making it impossible to test without signing up with unique emails.” - QA Tester, Cold Banana
Test SMS and email in one place
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, project or product. All Mailosaur servers come with a wildcard domain, letting you use any email address, without creating them first.
How it works
Boost end-to-end test coverage in minutes, by integrating with Mailosaur
Send an email or SMS message
Trigger a process in your product that sends out email or SMS (e.g. requesting a password reset)
Fetch the email from Mailosaur
Use one of our client libraries to detect and pull the email down into your test code.
Complete the process
Whether its checking the content of the message, following a link or using a verification code. Complete the end-to-end process you're testing
Embrace CI/CD with end-to-end automation
Integrate with any CI platform
Seamlessly integrate email and SMS testing into any build pipeline, including support for GitHub Actions (links), Jenkins, TeamCity and more.
Automate with your favorite framework
Create tests in any language
Mailosaur’s straightforward client libraries provide support for all major languages, including Node.js (links), Java, Python, .NET, Ruby, PHP and Go.
