Mailgun Pricing Overview

The documentation for their API is pretty well done, so it is easy to implement their solution. We strictly used it for email validation. Review collected by and hosted on G2.com.

There are multiple downsides to Mailgun, but the level of support is one. We typically would perform a few thousand client-side email validations per month. One month, we ended up with over 400,000 in a single day, that were due to bad actors. We would have assumed Mailgun would have protections in place to prevent a couple of IP addresses from running up an account, but they don't and wanted to charge us for all those email validations.

The worst part is we don't even have a way to "see" these validations. They literally just have a master counter with no report or anything showing the validations that took place, so the counter could just be whatever they want to make up.

When explaining to support our use of their API for client-side email validations, they simply wouldn't listen and kept providing generic boilerplate responses to reset all our "private" API keys, which were never even used. Review collected by and hosted on G2.com.

We just signed up for the Scale 100k Trial. We had attempted to sign up for a dedicated IP and the rep told us it wasn't a good fit unless we send 3k emails per month, even though when I made the request I mentioned we send between 50k to 100k per month. This was an automated response or the rep didn't read the questionnaire. It's now 24 hours later and I still haven't heard back. The "Optimize" portion is quite expensive. Nearly $200 per month to monitor domain health and email verifications. There are much better solutions on the market. Review collected by and hosted on G2.com.
