Illingworth skipped warmup and says it held
Richard Illingworth says he has been running live campaigns with almost no warmup and most held deliverability, against the three-week rule everyone repeats. He is still testing, so treat it as an early signal, not a licence to send cold off a fresh domain.

Illingworth says live campaigns held with almost no warmup
Richard Illingworth says his team has been running live campaigns with almost no warmup and most of them held their deliverability. His read is that warmup buys nothing permanent and that low daily volume plus genuinely clean domains is what decides placement afterwards. He adds that he is still actively testing and calls the signs early.
a warmup doesn't buy you a permanent free pass.
Campaigns and numbers
Abraham says 2,412 emails returned 18 leads in a playground niche
Nick Abraham says a client selling hardware to children's playgrounds, museums and schools got 18 leads in 7 days off 2,412 cold emails. He says the copy was only relevant social proof from similar customers plus a 5-year warranty as risk reversal. His argument is that the industry choice did the work, because these buyers rarely get cold emailed.
The BEST industries to cold email into are ones that rarely get cold emailed.
