Welcome to Sentvia — the email layer built for AI agents. Provision real inboxes on demand, send and receive mail, thread conversations automatically, and react to incoming messages in real time over webhooks, all without managing SMTP servers, DNS records, or sender reputation.

Quickstart

Create an inbox and send your first email in under five minutes.

Authentication

API keys, the base URL, and how every request is authenticated.

Inboxes

Understand how inboxes work, including addressing and limits.

API Reference

Every endpoint, parameter, and response schema in one place.

​
What you can build

  • Support & sales agents — give your agent its own inbox, let it triage inbound mail, and reply in-thread so conversations feel native to every mail client.
  • Per-user inboxes — spin up a fresh address for every customer, workflow, or task in a single API call; tear it down just as easily.
  • Transactional senders — send invoices, receipts, and alerts with deliverability handled for you, including SPF, DKIM, and DMARC.
  • Automated email workflows — trigger any downstream action the moment a message arrives, using webhooks and the message.received event.
  • Multi-agent pipelines — route mail between agents in a pipeline by assigning each stage its own Sentvia inbox.

​
How to get started

1

Create an inbox

Call POST /inboxes with a local_part and display_name. Sentvia returns a live address like support-bot@mail.sentvia.ai — no DNS setup required.
2

Send and receive mail

Send with POST /messages. Inbound replies are parsed, threaded, and delivered to your webhook endpoint or available via GET /messages.
3

Subscribe to webhooks

Register a webhook with POST /webhooks and listen for events like message.received. Sentvia signs every delivery so you can verify authenticity.
