A warmup schedule is a plan for gradually increasing sending volume to build reputation. Learn how to structure a warmup schedule and avoid common mistakes.
A warmup schedule is a structured plan that increases email sending volume gradually over time. It’s used when starting a new domain, mailbox, or dedicated IP so inbox providers see consistent, non-spammy behavior.
A good schedule starts with small sends to engaged recipients, then ramps up steadily while monitoring bounces, complaints, and engagement. The exact ramp depends on your baseline reputation, audience quality, and provider constraints.
Common mistakes include jumping to large sends too quickly and warming up on cold lists. Warm up on real engagement, keep content consistent, and pause ramp-ups if complaints or bounces spike.
