Give your AI agents email intelligence, not just raw email data
Turn raw email threads and their attachments into structured, cited context that a language model can reason over immediately.
A single natural-language request replaces multi-endpoint retrieval, running recall, context shaping and answer generation in one pipeline.
Semantic and keyword search are combined, filtered and reranked in a single call for higher-precision results.
Threads are rebuilt across time, participants and attachments, and answers always link back to the source messages.

Give every AI agent a real inbox and one API to use it
Provision mailboxes on verified domains or a shared myagent.mx address, with clean JSON output that strips signatures and quotes.
Send over HTTP or SMTP using the same mailbox credential as a Bearer token and SMTP password, with Idempotency-Key retries and attachment support.
Bind keys to providers, delivery groups, weights, and quota windows so traffic stays inside the boundaries you set.
Signed webhooks for delivery and receipt events, an SSE stream for live mailbox clients, and typed change polling for resync.
