Mailosaur makes it easy to test emails and text messages before they reach real customers. Instead of setting up your own mail servers or devices, you can send all test messages to Mailosaur and check exactly what users would see. QA teams use Mailosaur to: - Confirm that messages send when they should (like password resets, sign-ups, and account changes). - Test multi-factor authentication (MFA) and one-time passcodes (OTP) to make sure users can always log in securely. - Check links, images, and attachments work correctly. - Verify content and designs look right across different devices. - Automate message checks as part of their normal testing process. With Mailosaur, you can spend less time fighting with test environments and more time making sure your product works the way it should. ## What is Mailosaur used for?

A strong choice for email QA automation with a few cost and usability drawbacks." 5.0 Overall Rating 5.0 5.0 Ease of Use 5.0 5.0 Features 5.0 5.0 Customer Service 5.0 5.0 Likelihood to Recommend 8/10 January 20, 2026 Pros Mailosaur is a very handy tool for anyone doing automated email testing. The API is clean and easy to work with, and the documentation provides solid examples, so getting started is quick. It reliably captures OTP codes, password reset links, and other transactional emails, and it’s great for validating HTML, text content, and attachments. Emails usually arrive within seconds, and the shared inbox setup works smoothly for teams using CI/CD or multiple environments. Cons The pricing is definitely on the higher side compared to alternatives, and the limited free trial means you end up upgrading pretty quickly. For small companies, the SMS testing feature in particular can get expensive, which makes full end-to-end verification harder to justify. The dashboard could also use some improvements—searching and filtering messages isn’t as intuitive as it could be, especially in larger test suites. Very occasionally emails arrive with slight delays, and the lack of a self-hosted option may be a drawback for teams with stricter security needs. Nathan G. CTO Used the software for: Less than 1 year ### "Easy to use and very flexible" 4.0 May 16, 2023 Great solution for our automated test suite to both handle real SMS and email testing programatically. Pros Provided a lot of options on how to use it at a very cost effective price point. Cons Some of the docs where not super clear on how to interact with it via the API. EM Engineering Manager Engineering Manager Used the software for: 3-5 years ### "Mailosaur for test automation" 5.0 Overall Rating 5.0 5.0 Ease of Use 5.0 5.0 Features 5.0 5.0 Customer Service 5.0 5.0 Likelihood to Recommend 10/10 May 16, 2023 Good, I think the service we pay for and use with email is great and very reliable, we have not experienced any failures due to Mailosaur. I would like some cheaper ways to use their SMS services. Pros We picked up Mailosaur as an off-the-shelf way to test our email flow. A lot of our automation that deals with email relies on it. The setup for validating links inside of the emails was very easy to work with in the Mailosar API, something I was looking for in a tool like this. Cons We would love to use SMS features, but the pricing is more than we are willing to commit to currently. Also not a fan of per-user pricing on a tool like this where the volume is also priced. We have limited seats. SE Software Engineer Software Engineer Used the software for: Less than 1 year ### "Great product for automation testing" 5.0 Overall Rating 5.0 5.0 Ease of Use 5.0 5.0 Features 5.0 5.0 Customer Service 5.0 5.0 Likelihood to Recommend 6/10 October 18, 2023 I’m a very happy customer. 10/10 would recommend. Pros Ease of use for setting up extra emails and SMS Cons Hmmm tough question. The UI is great and I feel there is little to improve upon. QA QA and Observability Engineer QA and Observability Engineer Used the software for: 3-5 years ### "Best Product with features and secure" 5.0 Overall Rating 5.0 5.0 Ease of Use 5.0 5.0 Features 5.0 5.0 Customer Service 5.0 5.0 Likelihood to Recommend 10/10 January 24, 2024 Good product to use for automate your emails Pros It's easy setup and you can customize the functionality for 20 scrum teams Cons Phone Numbers support for SMS within The Netherlands , you cannot get a mobile number. Alexander L. Senior Software Engineer Used the software for: Less than 1 year ### "Easy to use and works well" 5.0 Overall Rating 5.0 5.0 Ease of Use 5.0 5.0 Features 4.0 4.0 Customer Service 4.0 4.0 Likelihood to Recommend 8/10 February 18, 2025 It works well for our needs. We need to enter real email addresses in our tests to not be blocked from sending because of too high of a bounce rate. We also need to test that the email, Authenticator and sms related features in our product work well. Pros It is easy to set up and works well. Provides APIs to easily use it in your end to end tests. Cons Don't really know. Haven't tried any competing products. I guess it could be cheaper or more seats be available in each tier. ST Senior Test Automation Engineer Senior Test Automation Engineer Used the software for: 3-5 years ### "Powerful tool for Automated testing of Emails and SMS" 5.0 Overall Rating 5.0 5.0 Ease of Use 4.0 4.0 Features 4.0 4.0 Customer Service 5.0 5.0 Likelihood to Recommend 9/10 January 29, 2024 Very positive, if I were to change company and they didn't have a Mailosaur license I would push to get one. Pros 1- Excellent customer support, they are very knowledgeable about their tool, every time I have ended conversations with Mailosaur support I have ended it with the solution to my problem. Customer support are very patient and respectable towards their customers. 2 - The API integration for the Mailosaur tool has a lot of great functionality and supports multiple languages Java, Python, C#, Ruby and Node.js. I have only used the Java API so that is all I can speak to, it's very reliable. 3 - It's nice to have a front end view into the Virtual mailboxes, it really helps debug defects. Cons There is usage limits based on the license price. It's completely understandable and very fixable, if the company I work for wants more Mailosaur resources, pay more money. The price you pay for Mailosaur depends on how you configure the below limitations. I really don't have any complaints about Mailsoaur so wanted to use this field to provide useful information. The usage limits currently apply to: Number of emails sent per day. Number of SMS messages sent per month. Number of phone numbers assignable. Number of registered users.

There was a minor issue with a function that was corrected almost overnight. Mailosaur has helped us scale our testing for our Dashboard product from it's formative stages to the critical application that it's become for our customers. Pros It was very easy to configure with Cypress and it provides us with demo users for presentations and manual testing Cons I really can't think of anything. Its never failed us. I've never received strange errors and the service is always up. Dale F. Software Developer in Test Used the software for: 1-3 years ### "great tool to quickly obtain test email links" 5.0 October 11, 2023 good, never had an issue with it Pros ease of implementation, easy to generate semi-unique domains Cons there is nothing that I do not like, if I had to choose something would be the limited number of users on some tiers of the account SE Staff Engineer Staff Engineer Used the software for: 3-5 years ### "Effortless" 5.0 Overall Rating 5.0 5.0 Ease of Use 5.0 5.0 Features 5.0 5.0 Customer Service 5.0 5.0 Likelihood to Recommend 10/10 May 17, 2023 I have detailed this in my blogpost \[sensitive content hidden\] Pros It is fast, reliable, easy to setup and use. The rollout at both companies I used it, Extend and Siemens, was successful, and easily adopted by all. Cons Some people prefer other services because they are free. You get what you pay for, this is not a problem for me.
