Cold email warmup planner
A new sending domain has no reputation, so the first three weeks are a scheduling problem, not a copywriting problem. Fill in the four fields: the schedule is computed in your browser, nothing is sent anywhere, and no address or campaign data is stored.
| Day | Date | Sends | Cumulative |
|---|
The four stop rules
- Hard bounce rate above 2% in a day: stop the day and find the source of the addresses.
- Spam complaints above 0.1%: stop the campaign, not just the day.
- Any reply ends that person's sequence — the reply is the goal, not an interruption.
- Opens halving while sends stay flat: drop back two ramp days before continuing.
How the ramp works
Day 1 starts at 20 sends (or your target, if it is smaller) and each following day is 50% more than the previous one, rounded, and never above the target. That is the shape most receiving filters expect from a domain that is building history. If you have several mailboxes, split the day's volume between them — one mailbox pushing the whole day is a signature, not a strategy.
Check the numbers before you send
The schedule tells you when you reach full volume; the test-size planner tells you how many contacts an honest test needs; the kill-rule calculator tells you when to stop. Use all three before the first send, not after the third.
