Warm-up schedule calculator
Tell us how many cold emails you want to send a day. We'll work out how many mailboxes you need, and show how each one ramps up day by day until it's ready.
Each mailbox, day by day
While a mailbox warms, each day's limit covers warm-up and cold together. Once it's ready, cold stops at 15 a day and the rest of the 30 goes to warm-up.
Week by week
How the schedule works
Ready in days, not weeks
On the standard schedule a new mailbox sends 3 emails on day 1 and 3 more each day after, so it is ready on day 5 (day 4 on Starter). Accelerated starts at 5 and grows by half each day, ready on day 4 (day 3 on Starter).
Then 15 cold a day
While it warms, a mailbox's daily limit covers warm-up and cold together. Once ready, cold sends cap at your plan's limit: 10 on Starter, 15 on Growth and Scale.
Never more than 30 a day
Warm-up and cold together stay at or under 30 per mailbox. Once cold reaches its limit, the rest of the 30 goes to warm-up, which never stops.
Set up, warm up and send from one app.
