Update to my review following the team's reply:

1. This is not my first experience with this type of service. I am well aware of how these tools operate.
2. I genuinely tried multiple times to add a domain for emails in your system. But your interface never once showed the actual reason for the errors.
3. Instead of making the service actually workable, you almost immediately sent me a link to buy ready-made mailboxes tailored for your platform.
4. I can only conclude that selling this LTD (Lifetime Deal) is nothing more than a bait-and-switch tactic to upsell and lock in paying customers.
5. For several days, the service was completely down. You sent a screenshot showing a massive spike in server load, and only after that did the service come back online. This means you either don't monitor your uptime at all, or you do a very poor job of tracking performance. That is definitely not what I expect from a B2B tool.
6. I got tired of trying to find a workaround for your service and ended up paying for SalesBlink. Compared to yours, everything there is running perfectly so far. It took me less than 15 minutes to connect multiple email providers and set up 30 mailboxes simply by connecting my Hermes agent via MCP. I don't know how it will perform in the long run, but I can say right now that it has a much more intuitive and user-friendly interface, highly detailed and clear documentation, and highly functional API and MCP integrations. These allow you to drastically expand the platform's capabilities, as well as manage and interact with it remotely.
7. And yes, your support did respond to my ticket, but after that, I had no desire to return to your platform. I even tried to find your roadmap, hoping that the necessary, modern updates might be on the way. But all I saw were endless user complaints about your confusing interface, making me realize that you are intentionally ignoring the problem. I left an honest, objective review stating exactly what was missing (and I didn't even mention a competitor right away).
8. Instead of taking this feedback on board—from someone who spent a significant amount of time testing your app and reporting the issues found—you decided to blame your customer. Objectively speaking, because of your platform, my campaigns are now launching two weeks late.

Unfortunately, the interface is very outdated and highly illogical. It provides no feedback when errors occur, and sometimes it throws error messages for issues that definitely don't exist. I spent a lot of time trying to add sending domains, but nothing worked out, and it's impossible to figure things out without support. The API integration is also very weak. I was highly disappointed by the lack of integration with modern AI agents, including the ability to connect and configure via MCP. I didn't even get to test the actual functionality—honestly, it was just a massive waste of time.
