Illingworth says a reply rate drop almost never means buying domains
Illingworth says a reply rate going 4%, 3.9, 4.1, then 1.9 almost never needs fresh domains. He reads drift at domain level, median of three inboxes, checks whether siblings dropped too, then sends a bland test to his own inboxes. If it fails, he rebuilds accounts in a new Google admin panel for a different IP, 2-3 days, no warmup.
Google assigns the sending IP through the admin panel an account is built in.
Campaigns and numbers
Christian: info@ lists booked a lead every 55 contacts, business emails 95
Christian listed ten cold email tactics he says come out of 10M+ sends. One local list split into 3,621 business emails and 4,553 personal or info@ ones, and the personal ones booked a lead every 55 contacts against 95. He also drops the unsubscribe link, asking people to reply "banana" instead so opt-outs come back as replies.
A campaign using {PROJECT} and {LOCATION} variables hit a 14.5% reply rate, while the same script without them sat at 1-3%.
Workflows and tooling
Lieben publishes the Claude Code setup behind his micro-list play
Michel Lieben published a Claude Code list build and says the lever is sending to 500 prospects, not 100,000. Standing rules go in CLAUDE.md under 200 lines, ICP and angles in brain.md, accounts tiered T1 to T3, phones enriched for T1 only.
