Real inboxes for every agent.
Email is Sentvia's core. Give each agent its own addressable inbox with full two-way send and receive, native threading, webhooks, and production deliverability — provisioned by API at any scale.
Everything an agent needs to live in the inbox
An inbox per agent
Create real, addressable inboxes programmatically — one per agent, thousands via API.
Full two-way email
Send and receive from real addresses. Your agents read, parse, and reply autonomously.
Native threading
Replies group into conversations automatically — multi-party, cc, bcc, and forwarding included.
Real-time events
Webhooks and WebSockets stream inbound mail the moment it lands — no polling required.
Production deliverability
Custom domains with SPF, DKIM, and DMARC, plus dedicated sending reputation as you scale.
Multi-tenant ready
Isolate inboxes per customer so platform builders can ship agent email to their own users.
Built for fleets of agents, not teams of people
Inboxes that scale with agents
Agent fleets need an inbox per agent, not per team. Sentvia Scale ships 1,500 inboxes for $99/mo — far more inbox per dollar than email APIs built for humans.
Lower cost at every tier
Sentvia Pro is $19/mo for 100 inboxes and 20,000 emails. You scale agents without an inbox-sized bill.
Familiar API, MCP-ready
A REST API with Python and TypeScript SDKs plus an MCP server, so your agents send and receive with a few calls — or a single tool.
Email API questions
What is an email API for AI agents?+
An email API for AI agents lets software create dedicated inboxes programmatically, send and receive messages, preserve conversation threads, and react to inbound mail through webhooks without a human mailbox UI.
Does each AI agent get its own email address?+
Yes. Sentvia can provision a separate, addressable inbox for each agent, with isolated message history and a consistent identity for ongoing conversations.
Can Sentvia receive email as well as send it?+
Yes. Sentvia supports full two-way email: send, receive, reply, forward, cc, bcc, attachments, and native threading, with inbound events delivered through webhooks or WebSockets.
How do AI agents connect to Sentvia?+
Agents can use Sentvia's REST API, Python SDK, TypeScript SDK, or MCP server. The API handles inbox provisioning and message operations while webhooks and WebSockets deliver real-time events.
