Copilot: the AI drafts, you approve.
Autopilot: it sends.
Run copilot two weeks first.
Whatever you keep rewriting is what your AI still does not know about your business.
Check it monthly. Same day, same place, write the number down.
The trend tells you more than the number. A domain rarely dies suddenly. It slides for six weeks while nobody is looking.
Never send to an unverified list.
Run it through a verifier. Delete hard bounces. Put catch-all addresses in their own group and send them last, in small batches. They bounce at 5-15%.
Ten minutes. Highest return hour in outbound.
Start at number 1 even if it is only 50 people.
50 contacts with a reason beat 5,000 without one, and it is not close on either replies or domain health.
The uncomfortable version of this lesson:
Big lists exist because loosening a filter is easy and making a decision is hard.
The decision is the work. The filters are just where you record it.
