AutoSend has been a total game-changer for us at First Dollar. What sold us initially was their team - super responsive whenever we had questions. And the fact that we could add all 190k users on just our basic $10/$20 plan without hitting some annoying contact limit was huge for a new startup like us.
Their email builder saved us so much time, and the spam check feature is actually useful.
Honestly, the best part has been how available their team is. Whenever we get stuck, they're up for a quick call to sort things out. Got us up and running with almost zero hassle. We literally use it almost every day now. Definitely one of the better decisions we made for our stack.

We chose AutoSend because it treats email as a first-class skill for LLMs and AI agents, not just a generic notification tool. Most alternatives focus on traditional workflows, while AutoSend actually fits how agents think and act.
We use it to let our LLMs send transactional emails directly as part of their decision flow, and it's been simple, reliable, and easy to integrate. If you're building AI-driven systems, AutoSend just makes sense.
