Dedicated IP
A sending IP reserved for one customer.
A dedicated IP isolates a senders reputation from the shared pool. Useful at high volume (1M+/mo) or for regulated industries that need predictable reputation. Below that volume, a dedicated IP can hurt deliverability because mailbox providers cannot build a reputation profile.

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 dedicated ip, 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.
