Customer Reviews
Value with annual plan
As a first-time user, I was looking for the best deal. I saw they had a discount for annual billing, so I went for that to get 20% off. It made the "Email API for AI agents" much more affordable for my project budget. The developer credits also helped me test things out without committing too much upfront. It felt like a good investment for the features I got, especially with that annual saving. Made it worthwhile for a small startup.
Easy to get started
Needed a way for my AI to send emails, so I checked out Mails.ai. I grabbed a developer API key. It was pretty easy to get it hooked up, which was a relief. The dashboard for agent inbox management was simple to understand. No confusing tech jargon, just got it running. It's been handling the transactional email for agents without any fuss. Smooth experience overall.
Good for agents, few small things
I used their per-agent email addresses and the prompt injection scanning. The scanning feature was good, caught a few things I missed. Setup for the email addresses was straightforward enough. My main gripe is that the documentation for integrating with less common LLMs could be clearer, took a bit of digging to get it perfect. Overall, it's a solid tool for AI agent communication, but a few more examples in the docs would save some time.
Reliable for agent emails
This was my third time using Mails.ai, specifically for their per-agent email addresses and reputation management. My previous experiences were good, and this one was consistent. The setup is pretty much the same each time, which is nice. I appreciate that the email deliverability for AI agents remains solid. I keep coming back because it's reliable and I haven't had any major headaches with it across multiple projects. It just works.
API worked fine
I needed the Email API for AI agents. Signed up, got the key. Integrated it into my system. It worked as expected. No issues so far.
