AI takeaways
Keep the key points here, or take a source-aware text brief into Claude, ChatGPT or another AI workspace.- 01Define which system should own mailbox operations, campaign state, replies and CRM disposition before comparing products.
- 02Keep authoritative records and policy outside the presentation layer.
- 03Require buyer-run failure, recovery and correction evidence.
- 04Use explicit denominators and keep vendor outcomes quarantined.
Compare one controlled campaign across mailbox setup, routing, reply classification, suppression and CRM write-back. Reject any option that hides failures or creates duplicate authority.

- Control: visible safe fallback and exception ownership.
- Control: source-linked evidence, correction history and reproducible tests.
- Control: review triggers for product, data, policy, price, security or legal change.
