Mailboxes and domains that Warmerly hosts for you, with the DNS and warmup handled. You can buy a new domain, bring one you own, or add mailboxes to a domain you have. A OneMail mailbox is billed per mailbox and never uses your plan's mailbox limit. See [OneMail](https://warmerly.com/docs/help/onemail-mailboxes).
