How long does email warmup take?
Email warmup takes 3–4 weeks for a new domain. Start at 8–12 emails per day per inbox with real engagement (opens, replies, spam rescues), then ramp gradually to your full volume of 30–50 emails per day. Rushing the ramp is the #1 cause of new domains landing in spam.
