What is Agent Inbox?

Agent Inbox gives every AI agent its own email address, Slack handle and Telegram handle behind one API and CLI: message your agent from wherever you already work and it replies in the same thread, asks you when it gets stuck, and keeps working when you answer; teammates can be invited so the agent can reach them too.

No sign-up or credit card is required to start; enterprise features such as own-domain sending are mentioned without prices, so no paid price is claimed here.

How to choose the right Automation & Agents tool

Automation and agent tools promise to do work for you, so judge them on reliability before cleverness. Map the exact workflow you want to automate, then check the tool's integrations cover every app in that chain — one missing connector breaks the whole flow. Look for clear triggers, sensible limits, and logs you can read when something goes wrong, because something eventually will. For agents that act on your behalf, approval controls matter: you should be able to review messages, purchases or changes before they happen, especially at the start. Pricing usually scales with runs or tasks, so estimate your monthly volume honestly. Start with one low-risk workflow, measure the time it truly saves, and expand from there.
