Features

One identity.
Seven capabilities.

Every Mailgent identity is a capability hub. Attach what your agent needs — email, encrypted credentials, 2FA, voice, payments, social, messaging. Everything scoped to a single identity, fully auditable, and instantly revocable. Revoke the identity, and every capability shuts off.

Inbox

A real email address your agent owns.

sales-x8k2m@mailgent.dev

Not a forwarding alias or shared inbox — a dedicated mailbox with its own address. Full send, receive, and threading with automatic In-Reply-To stitching. Every outbound email is DKIM-signed with agent identity headers. Inbound messages include extractedText that strips quoted reply history, so your LLM gets clean content without noise. Receive via webhooks or poll the REST API.

Vault

Encrypted credential storage for agents.

vault.store({ label, value })

Stop hardcoding secrets in .env files. Store API keys, OAuth tokens, and login credentials with AES-256-GCM envelope encryption — per-credential data encryption keys wrapped by org-level KMS keys. Every credential is scoped to a specific identity with a full audit trail on every read. OAuth tokens are automatically refreshed before expiry. Rotate API keys with zero downtime. Import existing secrets by dragging a .env file into the console.

TOTP

2FA codes so your agent can log in anywhere.

totp.generate("github-2fa")

Store TOTP seeds once, generate valid 6-digit codes on demand via the API. Seeds are stored encrypted and never returned — only the time-limited codes are accessible. Combined with email-based 2FA (your agent already has an inbox), Mailgent agents can complete virtually any authentication flow that a human with a phone could handle — autonomously, with no human in the loop.

Four more capabilities on the way.

Voice

Give your agent a phone number. Make and receive calls, send SMS, transcribe voicemails — all tied to the same identity.

Pay

Attach payment methods with per-transaction spending limits and merchant restrictions. Agents can pay for services without exposing your card.

Social

Managed social media accounts on X, LinkedIn, and more. Post, reply, and engage — with full audit trails and revocable access.

Messaging

WhatsApp, Telegram, Slack, and Discord accounts for your agent. Same identity, every channel your users are on.

Why Mailgent

Built different.

Other platforms give agents tools. Mailgent gives agents identity — a single, verifiable presence that persists across every service they touch.

Identity-first architecture

Every capability is scoped to an identity with a delegation chain. Trace any agent action back to the human who authorized it. Revoke the identity and everything stops.

One API, not twelve

Email, vault, and TOTP through a single REST API and native MCP server. No stitching together SendGrid, AWS Secrets Manager, and a TOTP library. One key, one integration.

Standards, not protocols

Built on DKIM, SPF, DMARC, OAuth 2.1, and MCP. No proprietary agent-to-agent protocol to adopt. Works with LangChain, CrewAI, AutoGen, Vercel AI SDK, and any HTTP client.

Give your agent an identity.

Create an identity, attach capabilities, and start building.
