> Justin Glover from AI Scale Tips on growing newsletters with cold email

Justin Glover, founder of AI Scale Tips, on building newsletters with cold email sent from WarmInboxes inboxes.

Justin Glover founded AI Scale Tips and builds newsletters with cold email. In this review he covers his experience running that outreach on WarmInboxes.

Newsletter growth by cold email is a volume game played over months: each send asks for a subscription rather than a meeting, so the infrastructure has to hold up at a steady daily pace rather than in a short burst. Prewarmed inboxes start the sending without a warmup wait, and fresh domains carry it once the pace is settled.
