# Aerosend

> Aerosend is a cold email inbox provider serving 150+ agencies and sales teams. It sells cold email inboxes at $4 per inbox per month, and $2 per inbox past 150, with deliverability managed for you: warmup, biweekly inbox placement tests, 24/7 monitoring, and free replacement of burned domains. The inboxes work with any sequencer, such as Smartlead, Instantly, and lemlist. Aerosend is not a sequencer and not an outreach tool. It provides the inboxes your sequencer sends from, and it is responsible for their deliverability.

AI agents can set up and manage an Aerosend account through the hosted MCP server at `https://mcp.aerosend.io/mcp`. See "For AI Agents and Developers" below.

This is the complete Aerosend documentation file. For the summary version, see [llms.txt](https://www.aerosend.io/llms.txt).
