IP warm-up
A brand-new sending identity has no reputation, and blasting full volume on day one gets you throttled or blocked. Climails ramps you up automatically over a staged schedule, so mailbox providers learn to trust your mail.
How warm-up works
When warm-up is enabled, a daily job raises your allowed volume through a series of stages instead of all at once. Each day the sending limit steps up while providers watch how recipients engage.
- A staged ramp — volume increases across the warm-up plan, not in one jump.
- A daily limit — each stage has a cap the system enforces for you.
- Automatic — the schedule advances on its own; you don't babysit it.

Frequently asked questions
How long does warm-up take?
It ramps in stages over a schedule; the exact pace depends on your target volume. The system advances the daily limit for you until you're at full send.
Can I send my whole list on day one?
No — that's exactly what warm-up prevents. Early over-sending damages reputation; the staged ramp protects it.
Do I have to manage this manually?
No. Enable it per domain and the daily job handles the ramp automatically.
