"Effortless Email Testing with Mailosaur—It Just Works"
What do you like best about Mailosaur?

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.

What do you dislike about Mailosaur?

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.

"The one email platform for testing"
What do you like best about Mailosaur?

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.

What do you dislike about Mailosaur?

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.

"Powerful email and SMS testing service for app developers specially"
What do you like best about Mailosaur?

It's very easy to start using it, but if you can insert code and have sone technical skills it can get very deep and bring good insights.

Very cheap to start, even to just see how mails are received in different inboxes can be much more expensive in other solutions. Review collected by and hosted on G2.com.

What do you dislike about Mailosaur?

SMS testing is not as cheap and easy to start as emails. It just does what it does, you can't build or improve your mails here, it's just for testing and getting insights. Review collected by and hosted on G2.com.

"Not good enough"
What do you like best about Mailosaur?

My experince with mailosaur is not so good, our use case is we sent marketing emails to our subscribers but before active our campaign we need to test all link and attachments. In this case i think mailosaur is not usefull because why should we pay when all these features are available in free tools. Review collected by and hosted on G2.com.

What do you dislike about Mailosaur?

Not helpfull all tese features are available in free tools Review collected by and hosted on G2.com.

"Awesome easy to use email tool with REST capibilities"
What do you like best about Mailosaur?

After hand-rolling a Python script and trying various email providers and APIs, Malosaur was a breath of fresh air.

It had a simple interface and was easy to implement, first in Postman and then in Cypress, as our automation suite matured and grew.

It runs in our CI/CD pipeline, confirming new user credentials are delivered.

In particular, the additional information they return about emails as separate JSON objects saved us a bunch of time and effort parsing the message body. Review collected by and hosted on G2.com.

What do you dislike about Mailosaur?

Having it be so useful to our processes that I pay for it out of pocket and our accounting team can't seem to figure out how to make it reimbursable? Review collected by and hosted on G2.com.

A great, affordable, digital marketing solution. Does email and SMS really well and doesn't break the bank. Review collected by and hosted on G2.com.

"Overall great tool with some shortcomings in SMS"
What do you like best about Mailosaur?

Mailosaur combines mail and sms api messages into one. In doing this, viewing a combined view of emails and text messages - and searching/retrieving messages standard and easy. Review collected by and hosted on G2.com.

What do you dislike about Mailosaur?

The phone numbers provided by Mailosaur are not always easy/obvious to send SMS messages. For example, Vonage numbers may not necessarily be processed by all providers. This can lead you down rabbit holes trying to figure out why texts never came. Review collected by and hosted on G2.com.
