Case Study: The Department for Education strengthens secure 2FA testing with Mailosaur

The Department for Education - Customer Case Study

The Department for Education (DfE) needed a secure, compliant, and scalable way to test email and SMS notifications end to end, especially workflows involving two-factor authentication (2FA). Their existing approach used a patchwork of open-source tools, Mailinator, manual testing, and log-diving, which created compliance concerns, limited 2FA testing, and low test coverage.

Mailosaur provided DfE with a UK-based email and SMS testing platform, including virtual SMTP servers, device previews, and automation-friendly testing features. With Mailosaur, the team reported smoother automation, reduced manual debugging, greater confidence in 2FA workflows, and an estimated 120% increase in email testing volume, with adoption expanding across teams and departments.
