Warm-up and what the day count means

What warm-up is

Warm-up is a steady exchange of short, ordinary messages between mailboxes, with replies, so the mailbox has a record of real conversation. Every customer gets it, on Fullturn's shared warm-up network. A warm-up subject ends with a short tag such as WU-K3QZ7M so Fullturn can recognise its own mail. Only the warm-up text crosses between accounts; no contact, campaign or signature does.

A mailbox can be switched off the shared network (on its warm-up settings). It then warms up with your own mailboxes only.

What the day count means

Home shows, for example, Warm-up day 6 of 14. The day count is how many days of warm-up the mailbox has completed. By default a new mailbox needs 14 warm-up days before its first cold email.

• Sign-off needs more than days: a health score of at least 90, no hard bounce or complaint in the last 14 days, no pause or rule hold, and an inbox rate of 80 percent or more when it has been measured.
• After sign-off the mailbox starts at 5 cold emails a day and ramps up slowly. The slow ramp lasts until warm-up day 60.
• These numbers are the team defaults. They can be changed in the new-mailbox settings on Sending, Mailboxes.
• Warm-up carries on after sign-off and during any rest. Do not switch it off to rest a mailbox.

What you do

• Nothing, mostly. Connect the mailbox, leave warm-up on, and write your sequence and list in the meantime.
• If a campaign is ready but the mailbox is still warming up, the campaign screen names the mailbox and says what it is waiting for.
