Do I need to warm up my sending domains?

No. Mail goes out at a natural pace from the first day, and each domain's quota grows only when it has carried real traffic. There's no schedule to keep.

No. There's nothing to warm up and no schedule to keep.

  • Every sending domain sends at a natural pace from its first day: a steady drip across the sending window, never a burst.
  • Each domain has its own quota with each mailbox provider. It grows when the domain has shown it carries the traffic.
  • Time that isn't used is gone. Nothing is sent later to make up for it.

Traditional warm-up sends more each day, whether or not there's mail to send. Here, real demand sets the pace, so the evidence a quota grows on is always honest.

How it works: Natural pace, and why it isn't warm-up and Traffic governance.
