AI agent that sends emails
The identity and email layer for AI agents that send email. Give every agent its own inbox, its own domain, its own sender reputation, and a full audit trail of everything it sends and receives.
The problem
Your agent sends through Zapier or Make, but every email comes from a shared address with no agent-level identity.
GoHighLevel or Salesloft campaigns hit spam because dozens of agents share one sender domain with no reputation isolation.
When a recipient replies, there is no way to route the response back to the agent that sent the original message.
Your team asks what the agent sent last Tuesday and why. The send logs live in three different tools.
Scaling past a few hundred sends means managing OAuth tokens, rate limits, and deliverability across inboxes you do not own.
The solution
AgentMail is the identity and email layer for AI agents that send email.
Dedicated inbox per agent
Each agent gets its own address. Outbound emails come from a persistent identity that builds sender reputation over time.
Custom domains
Send from your own domain with SPF, DKIM, and DMARC configured per agent. Free tier includes 50 inboxes and 10K emails/month at console.agentmail.to.
Inbound webhooks for replies
When a recipient replies, the message lands in the same thread and your agent gets notified in real time via webhook.
Full audit trail
Every send, reply, and routing decision is logged and queryable. Know exactly what the agent sent, to whom, and when.
What your email-sending agents can do
Outreach
Cold outreach and first touch
The agent creates an inbox, composes a personalized email, and sends from a dedicated address that accrues its own sender reputation.
Follow-up
Automated follow-up sequences
The agent tracks replies via webhooks, then sends follow-ups from the same thread to keep conversation context intact.
Replies
Reply handling and routing
Inbound replies land in the sending agent's inbox, get classified by intent, and route to the right handler or escalate to a human.
Scale
Multi-agent send coordination
Spin up a separate inbox per campaign, client, or territory. Pods isolate each group so reputation and data stay separate.
AgentMail is built to scale.
Redundant infrastructure spanning multiple regions, so a message to your agent lands even when a region does not.
Provision an inbox in milliseconds. Nothing to verify, nothing to wait on.
Typed SDKs, REST endpoints, and webhooks. Your first send goes out the same afternoon.
Wire it up in ten lines
Full quickstart at docs.agentmail.to. Your first send goes out under a minute after signup.
