How to use it
- Pick the sending type; it sets the per-mailbox ceiling and the sensible ramp.
- Enter your target daily volume and how many mailboxes will share it.
- Keep the daily increase between 20% and 30% unless the plan says otherwise.
- Follow the checkpoints in the schedule; pause the ramp if bounces pass 2% or complaints pass 0.1%.
Frequently asked questions
How long does warming up take?
Typically four to eight weeks to meaningful volume. The planner shows the exact day count for your inputs.
Can I warm up faster?
Raising the ramp above 50% a day reads to providers like a compromised account. Add mailboxes instead — that scales volume without a sharp per-mailbox curve.
Do warm-up services help?
Automated send-and-reply networks generate engagement that does not reflect real recipients. Providers have got better at spotting them. Warming with genuine engaged recipients is slower and holds.
