IP warm-up

Start with your most engaged recipients and increase over weeks, watching bounces and deferrals. A new IP with sudden high volume looks like a spammer. IP warm-up is one part of the wider warm-up described under email warm-up.

Verify the list first; a few hard bounces on a new IP are weighed heavily.
