What does email warmup actually do?

It gives a mailbox a sending history by sending a small, growing number of warmup emails between your mailbox and a network of other mailboxes. Warmerly's warmup engine automatically opens them, replies with quoted text, and moves them out of spam if they land there, giving the mailbox a credible sending history that inbox providers weigh in their filtering decisions.

How long until a mailbox is ready to send?

The warmup ramp runs 30 days, starting at 4 messages a day and growing to 50 by day 30 (Gmail stops at 40 and Outlook at 30). You can launch campaigns sooner on a younger mailbox, which will send at a lower volume while still warming. The app shows each mailbox's warmth, today's limit and the reason for it.

Do I pay per mailbox or per email?

You pay per mailbox at a flat monthly rate. Each plan includes a number of mailboxes (1, 5, 25 or 100) at a flat monthly price, and paid plans have unmetered sending with no per-email meter. Only OneMail hosted mailboxes are a per-unit extra charge.

Will Warmerly get my LinkedIn account restricted?

No. Restrictions come from automated behaviour, sudden activity spikes, high-volume requests on dormant accounts, and low acceptance rates. Warmerly ramps activity gradually, keeps request volume at safe levels, and builds engagement before outreach, so your account looks like the real person using it.

I do email and LinkedIn myself. Does Warmerly cover both, or just email?

Both. Warmerly warms your Gmail or Microsoft 365 mailbox and your LinkedIn account, and runs LinkedIn outreach, from one login. That's the point of it for founders: you run the email-plus-LinkedIn motion without juggling two separate tools or two separate bills.
