Mailosaur Reviews & Product Details

What stands out to me is the effectiveness and simplicity. We have experimented with various tools for handling emails in test automation, particularly for OTPs and 2FA, and Mailosaur has consistently been the easiest to use—it just works. I also appreciate the generous trial program, which makes it straightforward to create a functional proof of concept. This, in turn, is easy to present to the team and management for final approval. I also like the python library that has helpful methods for extracting the codes and links without manually parsing the email structure. Review collected by and hosted on G2.com.

I honestly can't think of any drawbacks. If I had to mention something, it would just be a lighthearted observation: my colleagues often joke about the product's name. Review collected by and hosted on G2.com.

As a software test automation engineer, Mailosaur is one of our most valuable tools for ensuring our system works end-to-end and provides the signals we need to identify issues quickly. The user interface is highly intuitive and genuinely a joy to use, which makes day-to-day testing smoother and more efficient. I was up and running (integrated into my current test suite) in about an hour. Review collected by and hosted on G2.com.

I wish we were able to afford higher limits. Review collected by and hosted on G2.com.

What I like best about Mailosaur is how *frictionless* it makes email testing. You get reliable, instant access to test emails without hacks or flaky inboxes, plus super-powerful search and parsing (links, OTPs, attachments, HTML/text) that just works. It turns something that’s usually painful and brittle into a clean, fast, confidence-boosting part of the test suite. Review collected by and hosted on G2.com.

its main drawbacks are its pricing for higher usage tiers and occasional delays in email delivery during peak times. Some users may find the API documentation lacking advanced examples, and the UI, while functional, could be more modern. Additionally, there are limitations on attachment size and message retention, which may not suit all testing needs. Review collected by and hosted on G2.com.

Mailosaur is highly effective for email and SMS automation testing. It simplifies the process of capturing, inspecting, and validating messages in test environments.

Mailosaur can be expensive for larger teams or projects with high message volume. The message retention period is limited, which may require frequent cleanup or data export. Some advanced features may require additional configuration or are only available on higher-tier plans. Integration with certain frameworks could be improved for more seamless automation.

I like the simplicity of the design applied in Mailosaur. Work-wise, I love Mailosaur as it allows me to create multiple inboxes with different domains, but manage them all under one access and one view. Another thing I like about Mailosaur is its capability to integrate with familiar test automation tools like Cypress and Playwright. This allows tests which require email integration to be much easier. Review collected by and hosted on G2.com.

Experience-wise, I don't have any issue with using Mailosaur. However, since I am using one provided by my employer, I am unsure of the cost. All I can say it must be a good product and service as my employer continues to renew the services year to year. Review collected by and hosted on G2.com.
