InboxKit pre‑warmed mailboxes review
InboxKit is the only provider that lets you choose how long a pre-warmed mailbox has been warming, and price it accordingly.
What we like
- Choose the warmup age tier
- Per-mailbox pricing, same rate every month
- Google, Microsoft 365 and Azure options
What to watch
- One-time domain fee from $12.50 per domain
- Ownership and transfer terms not published
- No warmup log or seed report published
What InboxKit offers
Pre-warmed Google Workspace and Microsoft 365 mailboxes bought from a "prewarm inventory" in the dashboard, priced by how long the domain has been warming. Each domain gets an admin panel with 2FA. Fresh mailboxes, for comparison, start at $2.50 to $3 a month.
Where it falls short
- No published statement that the domain is registered to you or that admin access transfers outside the InboxKit panel.
- No warmup log or placement report published for pre-warmed orders.
- The domain fee is easy to miss: about $12.50 per domain on top of the mailbox price.
Head to head with our pick: Getlead vs InboxKit.
