Capability tags — the atomic taxonomy. Open an agent for the full list.
Field notes
A service that already sends transactional email and wants an agent to classify incoming replies or draft a response.
Caveat — Inbound processing is listed on Pro and Platform plans; confirm the receiving allowance for your plan. Your application still owns conversation state, approvals, and agent behavior. Documentation reviewed October 12, 2026; no hands-on delivery benchmark.
