AI agent that follows up automatically
The identity and email layer for AI agents that follow up automatically. Every agent gets its own inbox, threaded replies, and webhook-driven triggers for every follow-up it sends.
The problem
Your agent sends follow-ups through HubSpot or Outreach, but every message comes from a shared address nobody monitors.
Replies to automated sequences in Salesloft or Instantly land in a generic inbox with no routing back to the agent.
Follow-up threads break the moment a prospect replies, so the agent loses conversation context and sends duplicates.
Salesforce or Apollo logs show the send, but there is no audit trail linking the follow-up to the agent that triggered it.
At scale, Mailchimp and ActiveCampaign rate-limit your sends with no per-agent reputation or tenant isolation.
The solution
AgentMail is the identity and email layer for agents that follow up automatically.
Dedicated inbox per follow-up agent
Each agent gets its own address. Follow-ups come from a consistent identity that builds sender reputation over time, not a shared alias.
Webhook-driven triggers
When a prospect replies, a webhook fires with the full thread so your agent can decide the next step: reply, pause the sequence, or escalate.
Native threading for every reply
reply() keeps every follow-up in the same thread. The prospect sees one clean conversation, and the agent keeps full context.
Full audit trail
Every follow-up sent, reply received, and routing decision is logged and queryable. Compliance reviews take minutes, not days.
What your follow-up agents can do
Sequences
Multi-step follow-up sequences
The agent sends a sequence of follow-ups on a schedule, each in the same thread, and pauses automatically when the prospect replies.
Triggers
Reply-based branching
Webhooks fire on every inbound reply. The agent classifies intent, updates CRM state, and picks the right next message in the sequence.
Routing
Escalation and handoff
When a reply signals buying intent or a complaint, the agent forwards the full thread to a human with all context attached.
Scale
Per-agent reputation at volume
Each follow-up agent maintains its own sender reputation. One agent hitting a spam filter does not take down the rest of your fleet.
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.
