You connect the mailboxes on the call, so you leave with warmup running rather than a list of things to do. There are three ways in, and the call uses whichever fits your setup.
Microsoft 365 and Outlook.com use Microsoft sign-in, which asks for only two mail permissions: IMAP.AccessAsUser.All and SMTP.Send, which means read and send mail and nothing else. Google Workspace and gmail.com use a Google app password, a credential separate from your account password that you can revoke from your Google account at any time. Any other provider connects over IMAP and SMTP.
- Everything Warmerly stores is encrypted at rest, and you can disconnect a mailbox at any time.
Before anything is sent, Warmerly reads your DNS: the SPF chain, the DKIM selectors, the DMARC policy and the MTA-STS state. The result is a baseline health score for the mailbox. On the call your real records are on screen, and you are told which one is costing you the inbox and exactly what to publish where.
Warmerly does not edit DNS for domains you own elsewhere. It tells you the record to publish and where, and you publish it at your DNS host. For domains Warmerly hosts for you, it keeps the records itself.
- SPF, DKIM, DMARC, MX and TLS are then re-checked every day.
- A failed check shows which record broke and the fix, not just an error code.
Every mailbox follows one ramp: 4 warmup messages a day on day 0, 8 on day 3, 15 on day 7, 25 on day 14, 35 on day 21 and 50 on day 30, rising in small steps between those points. It counts the days a mailbox has actually been warming, not calendar age or domain age.
A Gmail mailbox is held at 40 a day and an Outlook or Microsoft 365 mailbox at 30. If the health score or spam placement slips, that day's volume is cut back. The call goes through what this means for when you can start sending campaigns, which the how-it-works page says to judge on signals, not on the calendar.
- There are no presets to choose between: it is one ramp for every mailbox.
- Warmup messages do not count towards any allowance on a paid plan.
If Warmerly is the wrong tool for what you are doing, you are told so on the call, and pointed to something better where there is something better. Fifteen minutes either way.
It is a working session rather than a demo, and there is no sales pitch. The call is free, needs no card and needs no Warmerly account.
- Right tool: warmup starts on the call.
- Wrong tool: you leave knowing that, and why.
