Case Study: Calendly streamlines email testing with Mailtrap

How Calendly Streamlines Email Testing with Mailtrap

Calendly, a popular meeting scheduling platform, needed a reliable and scalable way to test the approximately 40 million transactional emails it sends each month. With a large team of developers and QA engineers, their challenge was to streamline the email testing process, validate HTML, check spam scores, and prevent test messages from reaching real customers. They turned to Mailtrap for a solution.

By integrating Mailtrap's Email Testing and Fake SMTP server, Calendly automated its testing workflow. Each engineering and QA environment used dedicated, shared inboxes, allowing teams to easily capture, inspect, and compare test emails. Using the Mailtrap API, they automated the provisioning of test inboxes for review apps, significantly streamlining their development process. This solution provided a safe testing environment and brought organization and efficiency to their large-scale email operations.
