Warm up

A freshly connected number that starts sending a lot right away is easily flagged and blocked. Warm up mimics natural activity: warming accounts message each other automatically, growing the volume day by day.

The section lives under Campaigns → Warm up. The Start warm-up button on an inbox's Connection tab leads here too, with that number preselected.

How it works

A fresh number first stays silent for about a day (cooldown), then starts sending a few messages a day and gradually increases the count. Warm-up runs the conversations between accounts itself, on a schedule.

Starting

1. Open Campaigns → Warm up.
2. Pick a connected account.
3. Set the ramp parameters:
   • Start / day — the volume to begin at.
   • Target / day — the volume to reach.
   • Ramp (days) — how many days to reach the target.
4. Click Start warm-up.

Peer countries

When the warm-up pool has known countries for the channel, a "Warm on numbers from" block appears under the ramp parameters, listing countries and how many numbers each has.

• Warming against numbers from the same country the number will later write to builds a more believable local history.
• The "top up with other countries if there aren't enough" checkbox allows mixing in the rest. It is off by default: with few matching numbers you simply get fewer messages a day — other countries are never mixed in silently.

Extra options

• Skip the cooldown — if the number is already active, you can skip the silent day and start warming now.
• Manual override — set the volume freely, bypassing the safe daily increase.

Statuses and control

A pause isn't always manual: the reason is shown next to the status — "paused manually", "the account went offline" or "too many sending errors".

You can pause, resume or remove a warm-up. The account page shows its health (sent/failed over 7 days), a chart of incoming and outgoing per day and recent messages. A number that finished warming is marked "Ready for campaigns" there — mass messaging can run from it.
