Illingworth publishes the six sending rules behind his agency

Richard Illingworth listed the six SOPs he says got his cold email agency to 170k a month. The sending ones: every domain passes SPF, DKIM, DMARC and MX before launch, no inbox goes past 20 emails a day, no domain carries more than 3 inboxes, warmup runs at least 14 days and nothing launches below a 70% health score.

Taylor Haren says two weeks into his first full-service client, RB2B, his team found a typo replicated across 34 warmed-up domains that made every email look like phishing. A second set of warmed infrastructure was ready, which he says saved the campaign and the business after the wasted domains.
