Warm up your business mailbox.
Your mailbox trades short, ordinary letters with real business mailboxes in our network.
Those mailboxes open your letters and reply to them. When one of your letters lands in spam, the reader moves it back to the inbox.
You watch where your letters land each day: the inbox, promotions or spam.
How it works
The network writes short, plain letters for your mailbox, records where each one lands, and never writes to anyone outside the network.
How probation works
A new mailbox starts on probation for 14 days. During probation it sends 5 letters a day, and only to our own seed mailboxes.
After 14 days it joins the full network and works up to the daily number of letters you choose, between 5 and 60.
You connect with an app password from Private Email or Google Workspace. You can pause or disconnect a mailbox at any time.
Free during the beta
There is no card and no billing while we are in beta.
