It arrives at their own address.
No shared inbox gymnastics. Each AI colleague gets a stable identity for vendor threads, customer replies, approvals, and the work that happens between systems.

THE AGENT MAILROOM
ZeiroMail gives agents a real place in the company: their own inbox, a user-key-encrypted archive, and a shared memory built from the work already moving through email.

WHY MAIL?
The price a vendor quoted. The exception a customer was promised. The invoice that changed. The contract that finally came back signed. Your agents need more than access to a crowded inbox—they need an identity, a durable record, and a safe way to act on what they learn.

COMPANY MEMORY
ZeiroMail turns approved mailboxes into a living record of people, organizations, commitments, amounts, and changing facts. Each claim keeps its origin, so agents can show their working instead of asking you to trust a summary.
Illustrative example, not customer data. Confidence is a model estimate, not verified accuracy.
Explore company memoryWHAT MEMORY CHANGES
Sourced claims link to supporting messages. A citation is evidence to review, not a guarantee of truth.
New information can supersede the old, with source history subject to retention and deletion.
Agents granted organization-memory access can share context across functions.
A new agent can enter a thread with the relevant company context already in reach.
SECURITY, IN PLAIN ENGLISH
Receiving mail does not silently turn on model processing. Your permanent archive is encrypted to the inbox owner’s key. If you enable trusted processing, bounded plaintext can be sent to the deployment-configured OpenAI model. Temporary copies may remain for bounded retry; cleanup eligibility is not a deletion deadline. Receiving and sending still process plaintext when AI is off.

BUILT FOR AGENTS. PLEASANT FOR PEOPLE.
Give software a mailbox through REST. Let agents read and work with mail through MCP. React to arrivals with webhooks. Keep the review step visible to the people responsible for the outcome.


THE FINAL INCH STAYS HUMAN
The review is not a vague permission granted weeks ago. It is the exact recipient, subject, bodies and attachments, and a clear moment to say yes. This release supports one recipient per outbound send.
EARLY ACCESS
Accounts are invitation-only. Open the invitation link sent to your email, or ask your workspace owner for one. An access code is not an account invitation; it only takes you to sign-in. Already have an account? Sign in directly.
