Email Warmup Guide
How long to warm a new domain, what a safe ramp looks like, and when to stop.
What warmup actually does
Warmup builds a history of positive interactions from a new identity: mail that is delivered, opened and replied to rather than deleted or reported.
A realistic ramp
Start around five to ten sends per mailbox per day and increase gradually over two to four weeks. Older domains ramp faster than freshly registered ones.
Keep warmup running
Reputation decays. Leave a low level of warmup traffic in place while campaigns run rather than switching it off on launch day.
When to pause
Rising bounces, sudden placement changes or spam complaints mean stop, fix the list or the content, and resume at lower volume.
