A term from the glossary of Warmerly terms.

The mailbox every new account gets at signup, already warming up. It shows a Free gift badge on Accounts, uses no plan slot, and needs no DNS. It warms up and can be used for replies and tests, and, when a place is free on the shared domain, a small first campaign after 14 days of warmup (up to 3 emails a day). Inside Warmerly and in some answers you may see it called the "sandbox" or "free trial" mailbox. See How do I get a free sending mailbox?.
