# IP warm-up

Also called: Warming up

Sending a small amount of email from a new IP address or domain at first, and increasing it gradually, so mailbox providers learn to trust it.

## How this affects you

A new domain needs warming up too. In Vaartix, daily limits on a new account start low and grow with a clean sending history. If you move a large volume from another service, move it in steps rather than all at once. A new dedicated IP has no history and needs a warm-up over several weeks.
