Spam trap
An address used to detect poor list acquisition or hygiene.
Spam traps are addresses monitored by anti-abuse organizations or mailbox providers. They may be pristine addresses that were never opted in, or recycled addresses that used to belong to real people. Hitting traps is a strong signal of purchased, scraped, or stale lists.

An agent stack treats email as a two-way primitive. Inbound has to arrive as structured JSON a tool call can consume, sends have to be safe to retry when a model loop repeats itself, and every action needs an audit trail. A provider without inbound parsing only solves half the problem.
Applied to spam trap, that means weighing inbound parsing, idempotency keys, webhook coverage, and operating track record ahead of the rest, against inbound parsing into tool calls and model-generated sends that must not duplicate.
