Email Automation
Automate all emails from conversion to retention.
Create welcome sequences, onboarding flows, and re-engagement campaigns that send themselves automatically.
When to send?
Auto-pause if bounce > 2% or complaints > 0.05%. You'll get a daily email summary and an alert if warmup pauses.
Domain Warmup
Build reputation first,
and you'll never worry
about getting blacklisted.
New domains start with zero reputation. Send too much too fast and inbox providers flag you before you've had a chance to prove yourself. Autosend gives you a warmup schedule that ramps volume at the right pace, so you reach full sending capacity without the false starts.

AutoSend has transformed First Dollar. Their team is responsive and adding 190k users on our $50 plan was huge saving.

Switching to AutoSend was smooth. The migration was quick, the team responsive, and the product matches big players in features.
I'd recommend AutoSend to any startup.

We chose AutoSend for its first-class email handling for LLMs and AI agents, unlike generic tools. It fits how agents think and allows LLMs to send transactional emails easily.
