Agent Accounts
Email & Calendar for Your AI Agents.
Nylas Agent Accounts give your AI agents their own email and calendar through a single API. A complete communication identity — owned by your software, not borrowed from a person.
Same Nylas API your team already uses. Same
grant_id. Zero new endpoints.
Owned identity
Your AI Agent’s own mailbox. Not a borrowed one.
Most agents send from your inbox. Agent Accounts give each agent its own inbox and calendar, provisioned through one API call and hosted by Nylas.
-
Your application owns the mailbox and calendar
Enable agents to act as independent participants with total workflow ownership; autonomously handling every step from initial outreach to availability discovery and final booking.
-
Sends and receives as agent@yourco.com
Establish a working identity for your AI agent with a dedicated domain-based email.
-
No OAuth, no sign-in flow
Deploy agents instantly with one API call. Skip the friction of manual provider sign-in flows.
-
Enterprise-grade security for every agent
Every Agent Account inherits the security and compliance of the Nylas platform: SOC 2 Type II, HIPAA, ISO 27001, ISO 27701. Built in from day one.
Not just an email address. Every feature your agent needs.
Email, calendar, and the platform that powers them. A fully managed email provider built into the Nylas API your team already calls.
-
Email + Calendar API
One grant, one API. Your agent sends, receives, threads, and books from the same identity.
-
IMAP access
Standards-based. Any framework, client, or tool that speaks IMAP can connect.
-
Folders & organization
Folders, labels, and search. Your agent files, categorizes, and retrieves like a managed mailbox.
-
Email policy enforcement
Rate limits, allowlists, and send quotas keep a misbehaving agent from torching your domain reputation.
-
Spam filtering
Inbound spam stays out of your agent’s context window. Tokens go to messages worth processing.
-
Scheduling & availability
Read calendars, propose times, send invitations, and handle RSVPs from the same account.
-
Custom domains
Provision on yourcompany.com. Nylas writes the MX records. SPF, DKIM, and DMARC out of the box.
-
SDKs + MCP
Python and TypeScript SDKs in production. MCP server for Claude Code, Cursor, and 40+ coding agents.
-
Workspaces
Group multiple agents under one organization. Provision dozens of identities under a single set of policies.
Use Cases
Powering agents across every workflow.
From sales outreach to scheduling to inbox management. Agent Accounts give your agents the full communication stack under one identity.

Frequently asked questions
Need more help?
Let’s Talk!
An email address and calendar that belong to your software, not to a person. You provision them through the Nylas API. Your agent uses them directly. The same endpoints your team already calls for connected accounts work with the new grant.
Nothing new. Agent Accounts use the same grant_id pattern and the same Nylas endpoints. Every endpoint your team already calls works the same way for the new grant. One additional call provisions the identity, and the rest of your code stays as it is.
Most agent email offerings are a thin wrapper around send and receive. Agent Accounts are a fully managed email provider: IMAP access, folders, policy enforcement, spam filtering, deliverability, and calendar in the same account.
