Solutions / AI Agents & Automation
AI agents that email like professionals. Not like incidents.
Agentic systems increasingly act over email: scheduling, follow-ups, support triage, research outreach, order handling. Email is the one channel every business already speaks. It is also the one channel where a misbehaving agent can permanently damage your domain in an afternoon. We built the layer that makes agent email both capable and safe.
The context
Why agent email breaks differently.
To a mailbox provider, an AI agent that sends email is just another sender. It needs an authenticated identity (SPF, DKIM, DMARC-aligned), a sending reputation, rate discipline appropriate to each receiver, and a clean recipient list. The difference is tempo. A human makes mistakes one at a time. An agent in a loop makes them at machine speed. Guardrails that depend on someone noticing are guardrails that fail.
There is also the receiving side, which most agent stacks ignore entirely. An agent that sends but cannot receive is half a participant. Replies, bounces, out-of-office responses, and follow-ups all land somewhere it cannot see. Real agent workflows need actual mailboxes: addresses that can hold a thread, with programmatic access to what arrives. A fire-and-forget API endpoint does not cut it.
And agents need feedback. Delivery events (accepted, deferred, bounced, plus the exact server response) are the ground truth an agent needs to decide its next move: retry later, try another contact, mark the address dead, escalate to a human. Without that loop, agents keep mailing addresses that bounced yesterday. Which is exactly the behavior that gets domains blocklisted.
Your challenges
Where agent sending goes wrong.
Your agents send from identities that were provisioned by hand, with authentication nobody re-checks. One stale DKIM selector and every agent email starts failing DMARC.
An agent loop bug once sent hundreds of messages in minutes, and you found out from the complaint fallout.
Agents keep emailing addresses that hard-bounced before, because nothing feeds delivery outcomes back into their context.
Replies to agent email go to an unmonitored address. Threads die, and counterparties lose trust.
Compliance asked how agent-generated outreach honors suppression and unsubscribe obligations. There was no good answer.
How Egressif helps
What changes when the guardrails live in the infrastructure.
Programmatic identities, properly authenticated
Provision sending domains and mailboxes through our API, each with full SPF, DKIM, and DMARC alignment handled on our managed DNS. An agent’s identity is born correct, stays verified, and is observable like any other sender on the platform.
Real mailboxes for real conversations
Agents get standards-based mailboxes (IMAP/SMTP access) that receive replies, bounces, and follow-ups, with server-side filtering to tag, file, and forward what arrives. Threads survive because there is an actual mailbox on the other end.
Machine-speed guardrails
Per-identity rate caps stop a looping agent inside its own budget. A hard gate, not an alert someone reads tomorrow. Receiver-aware shaping keeps even well-behaved agents inside what Gmail, Microsoft 365, and the gateways tolerate.
Suppression the agent cannot bypass
Hard bounces, complaints, and do-not-contact entries are enforced at the delivery gate, below the agent’s decision layer. A confused agent cannot mail a suppressed address. The platform refuses on its behalf.
Delivery outcomes as agent feedback
Every outcome is recorded with the exact server response: accepted, deferred with a 4xx, bounced with a 5xx and its enhanced status code. Where your agent stack can consume a feed, we wire delivery events into it, so the agent gets ground truth to retry intelligently, drop dead addresses, or escalate. And the gate suppresses dead addresses regardless, so even a feedback-blind agent cannot keep hammering them.
Reputation isolation per workload
Agent traffic runs on its own identities and reputation, separated from your transactional and human-sent mail. An experiment in agent outreach can never take down your password resets.
A human safety net
Our deliverability team watches agent workloads like any other sender. Reputation drift, unusual patterns, and blocklist exposure get caught and contained, often before your own monitoring fires.

FAQ
Agent email, answered honestly.
Is this a "let your agent spam people" product?
The opposite. Agents here send permission-based, legitimate mail: scheduling, follow-ups, notifications, workflows your users asked for. The guardrails (rate gates, suppression, DNC and DNP enforcement) exist precisely so an agent physically cannot become a spam cannon, no matter what its prompt does. Unsolicited bulk is prohibited for agents exactly as it is for humans.
What stops an agent loop from burning our domain overnight?
Per-identity rate gates at the delivery layer. A retry loop or a runaway plan hits its hourly ceiling and stops at the gate, inside the first minutes, while the event stream shows you exactly what it was doing. The blast radius is one identity’s budget, never your domain’s reputation.
How does the agent know what happened to its mail?
Every outcome is recorded with the receiver’s response: accepted, deferred, bounced with classification, suppressed and why. Where your stack can consume a feed, we wire delivery events into it. And the suppression gate protects you regardless: a dead address gets refused at the platform even if the agent never learns.
Can agents receive and read replies?
Yes. Identities can come with real hosted mailboxes, accessible over standard protocols, so an agent can read replies, hold threads, and behave like a correspondent instead of a fire-and-forget script. Send-only automation is half a capability.
How do we provision identities for thousands of agent instances?
Domains and mailboxes provision programmatically through scoped API keys, each isolated with its own reputation and its own gates, with authentication handled on our managed DNS. The lifecycle fits inside your orchestration rather than a support ticket.

The problem
A scheduling agent shipped with a retry bug. When a recipient’s server greylisted it with a 451, the agent re-sent the full message immediately, every thirty seconds. By morning it had hammered one company’s gateway hundreds of times from your primary domain.
With Egressif
On Egressif, the per-identity rate gate would have capped the loop inside its first minute. The greylist would have been handled by the delivery layer on a proper schedule, not by the agent. And the delivery record would have exposed the bug immediately. One contained identity, zero domain damage, and a bug report instead of a blocklisting.
Give your agents email that can't embarrass you.
Domains, rough volume, current providers, and what hurts. You will get a straight answer on fit, and a real number, in one conversation.
