Knowledge Pipeline

Build repeatable ingestion pipelines for documents, sites, and drives, with extraction, cleaning, chunking, indexing, and retrieval testing before you go live.

Limitations

–Self-hosted deployments require real infrastructure and maintenance effort
–Complex multi-step workflows take time to learn and tune
–Advanced enterprise governance features sit behind a sales-quoted plan

Sendmux

Give every AI agent a real inbox and one API to use it

Agent mailboxes

Provision mailboxes on verified domains or a shared myagent.mx address, with clean JSON output that strips signatures and quotes.

Provider-flexible sending

Send over HTTP or SMTP using the same mailbox credential as a Bearer token and SMTP password, with Idempotency-Key retries and attachment support.

Routing controls

Bind keys to providers, delivery groups, weights, and quota windows so traffic stays inside the boundaries you set.

Real-time events

Signed webhooks for delivery and receipt events, an SSE stream for live mailbox clients, and typed change polling for resync.

Strengths & Pros

+One API for sending, receiving, routing, and events
+Inbox payloads tuned for LLM token efficiency
+Not locked to a single sending provider
+Practical developer tooling: SDKs, CLI, MCP, framework integrations

Limitations

–

Newer platform, so the surrounding ecosystem and community material are still small

–Using your own sending providers puts deliverability and domain reputation on you

–Agent mailboxes still depend on correct DNS setup for verified domains
