FAQ
Pre-Warmed Microsoft 365 Inboxes —
Frequently Asked Questions
Pre-warmed means the Microsoft 365 inbox has already completed a 12-week warm-up process. The account has an established send history that mimics natural human email behavior — so spam filters treat it as a trusted sender from day one of your cold email campaigns.
LiteMail pre-warms every Microsoft 365 inbox for a minimum of 4–6 weeks, with a full 12-week warm-up cycle completed. You receive inboxes ready to send cold email at volume without any reputation risk.
Yes — that is the entire point. No waiting period, no manual warm-up, no phased ramp-up. Plug pre-warmed Microsoft 365 inboxes into Instantly, Smartlead, or any sending tool via OAuth and launch cold email campaigns immediately.
Yes. Every plan includes domains: Starter gets 1, Growth gets 3, Pro gets 6, and Scale gets 12. Extra domains are $15/domain/year. The first-month price reflects domain inclusion.
