How it works
An account with warm-up on starts at 25% of its limits and rises a little every day until it reaches 100% after 14 days. A sudden jump from no activity to a full campaign is one of the clearest signs of automation; the warm-up avoids it.
The account card shows the progress ("Day 5 of 14") and today's numbers.
When to turn it off
Warm-up is on for every new account. Leave it on unless the account already sends invites and messages every day. You can turn it off in the account's Limits & hours, under Warm-up.
Cold email has its own volume ramp-up: new mailboxes start at 20% of their daily limit and reach 100% over 21 days. Mailboxes.
