Turn on Winnr's built-in warming, tune settings, and read the metrics.
New mailboxes on new domains hit spam filters harder. Warming ramps up sending gradually with realistic email exchanges so mailboxes look established when you start real campaigns. This explains the mechanics — volume ramp, engagement signals, and the 2-3 week timeline.
Pause warming temporarily (metrics preserved, billing continues) or disable it fully (no more warming emails, billing stops next cycle). This walks through both plus when each makes sense.
Health score is the top-line signal. Inbox rate, spam rate, and replies fill in the detail. This explains what each metric means, what values are normal, and when to worry.
The warming seed phrase is a single account-level marker Winnr adds to every warmup email your mailboxes send, so you can filter warmup mail out of your own inbox or sequencer. Set it once in Settings.
Enable Winnr's built-in warming on any mailbox from the Warming page. Pick daily volume and ramp speed. Costs $0.60 per mailbox per month. Runs in the background — first useful signals show within 3-5 days, full readiness in 2-3 weeks.
Winnr's warming works on any mailbox — including Gmail, Outlook, and Google Workspace accounts you own outside Winnr. Add the mailbox as an "external" user with SMTP/IMAP credentials, and Winnr warms it just like a native Winnr mailbox.
Warming is $0.60 per active mailbox per month, billed alongside your Winnr subscription. Prorated for partial months. Disabling warming stops the charge from the next cycle — pausing does not.
Each warming mailbox has two tunable settings — daily volume and ramp speed. This explains what each does, when to change from the defaults, and how the settings interact.
