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 have a sending history when you start real campaigns. This explains the mechanics, which providers warming does and does not reach, the volume ramp, and how long to warm.
Pause warming temporarily (settings kept, billing continues) or disable it fully (warming campaign removed, billing stops from the next cycle). This walks through both, in bulk or per mailbox, plus when each makes sense.
Health score is the top-line signal, and inbox rate and spam fill in the detail. This explains every card, chart and column on the Warming page, what values are normal, and when to worry.
The warmup 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 on the Warming page.
Enable Winnr's built-in warming from the Warming page or the Email Users page. Pick daily volume and ramp speed. Costs $0.60 per mailbox per month, with the first month charged when you enable. Plan on at least 2 weeks of warming, 4 on a brand-new domain.
Winnr's warming works on mailboxes you own outside Winnr too, including Gmail, Google Workspace, Microsoft 365 and any custom SMTP/IMAP mailbox. Import them from a CSV on the Warming page and warming starts immediately at $0.60 per mailbox per month.
Warming is $0.60 per warming mailbox per month. The first month is charged when you enable, then it renews with your Winnr subscription (or on its own monthly subscription if you only use warming). Disabling stops the charge from the next cycle; pausing does not. Warming-only accounts cancel from Settings → Subscription.
Each warming mailbox has three settings you control, daily volume, ramp-up on or off, and ramp speed. This explains what each does, how to change them per mailbox or in bulk, and when to move off the defaults.
