Email infrastructure built for AI agents, not humans

EmailCommunicationDeveloperAIAutomation

AgentMail gives your AI agents their own dedicated email addresses — provision mailboxes on demand, send and receive messages programmatically, and react to real-time events like deliveries, opens, clicks, and bounces. No SMTP configuration, no shared aliases, no DNS headaches: your agent has a fully functional inbox the moment it calls the API. Connect AgentMail to Actionist and your agents can run complete email workflows — triaging inbound leads, threading follow-ups, routing attachments, and enforcing SLAs — with the same precision they apply to every other tool in the stack.

Inbox-to-ticket in under 60 seconds

When a customer emails the support address, your agent reads the full message in the AgentMail inbox, classifies intent and urgency from the body text, provisions a thread reply acknowledging receipt with a ticket number, and pings the on-call engineer in Slack — all before a human has unlocked their phone. No manual triage, no delayed acknowledgements, no tickets created from memory.

FAQs

Questions about AgentMail + Actionist

How do I get an API key to connect AgentMail?
Log in to your AgentMail dashboard at agentmail.to, navigate to Settings → API Keys, and generate a new key. Copy it into the API Token field in Actionist — the agent uses it for all API calls on your behalf. Keep the key secret; if compromised, rotate it from the same settings page immediately.
Will agents send email from my real domain, or a generic agentmail.to address?
By default, each provisioned inbox uses the agentmail.to domain (e.g. agent-sales@agentmail.to). AgentMail also supports custom sending domains if you configure DKIM and SPF records for your own domain in the AgentMail dashboard — consult their docs at agentmail.to for the DNS setup steps.
How do I avoid trigger loops when an agent both sends and monitors an inbox?
AgentMail's webhook payload includes a direction field — set your trigger filter to inbound only so the agent never reacts to its own outbound messages. In Actionist, add a condition step that checks direction === 'inbound' before any processing logic runs. This one guard eliminates the most common loop scenario.
What happens to emails if Actionist is temporarily offline?
AgentMail queues webhook delivery and retries with exponential back-off for up to 72 hours. Once Actionist reconnects, queued events replay in order. For inbound emails, the messages remain in the AgentMail inbox indefinitely — you can also use the List messages action on reconnect to catch up on anything that arrived during downtime.
Can multiple agents share the same AgentMail inbox, or do they each need their own?
Each agent should have its own inbox — AgentMail makes provisioning cheap (one API call), and shared inboxes create race conditions where two agents process the same message simultaneously. Use the Create agent inbox action at agent-launch time and store the address in the agent's context.
Does AgentMail support email attachments for both sending and receiving?
Yes. The Send email action accepts attachment payloads (base64-encoded or a URL). On the inbound side, Get message details returns an attachments array with download URLs for each file. The agent can then pass those URLs directly to storage actions like AWS S3 upload or Google Drive file create.
How does open and click tracking work, and do recipients know they're being tracked?
AgentMail injects a 1×1 tracking pixel for opens and rewrites links for click tracking when you enable these options on a send. Recipients see the original link text but the URL is proxied through AgentMail's tracker. Note that many email clients block pixels by default, so open rates undercount actual opens — treat them as engagement signals, not exact counts.
What rate limits apply to the AgentMail API?
AgentMail's default plan allows 100 API requests per minute and 10,000 emails per month. The agent respects these limits automatically — if a burst of outbound sends hits the rate cap, Actionist queues the excess and retries after the reset window. For high-volume campaigns, contact AgentMail for an enterprise plan with higher thresholds.
