Sentio

Email inbox API giving AI agents their own real email address.

PlatformWebfreeglobal

Sentio is an email inbox API that gives every AI agent its own real email address, delivering received mail as structured webhooks and letting the agent reply in-thread over REST. It's a complete, self-hosted multi-tenant mail server in Rust with full DKIM/SPF/DMARC/DANE support and anti-spam. It's built for developers building AI agents that need to send and receive real email without standing up mail server infrastructure themselves.
