How the warm-up network works

Your business mailbox trades short, ordinary letters with other real business mailboxes in our network. You watch where each letter lands.

Letters between real mailboxes

Every mailbox in the network belongs to a business. Most days, inside the working hours you set, your mailbox sends a few short letters to other mailboxes in the network, and they send letters to it.

The network writes these letters for you, from the role and the short company description you give it. They are plain letters about ordinary work.

The mailboxes that receive your letters open them and reply to some of them. When one of your letters lands in spam, the mailbox that received it moves the letter back to the inbox.

Your mailbox does the same for the letters it receives. To do that, the network signs in to your mailbox with its app password. It looks only for the network's own letters and does not read the rest of your mail.

Probation, then the number you choose

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 probation it trades letters with the rest of the network. It works up to the daily number of letters you choose, between 5 and 60.

You watch where each letter lands

For each letter, the mailbox that received it records where it landed: the inbox, promotions, spam, or not found.

Your dashboard shows those counts for each day, and the share of letters that reached the inbox over the last 7 days.

What we never do

We never send a letter to anyone outside the network. Your customers and contacts never hear from us.
We never sell your data, your address or your letters.
We never put links in the letters.
We never delete mail, in your mailbox or in anyone else's.

You can pause or disconnect your mailbox at any time, from your dashboard. A disconnected mailbox sends nothing, and its app password is erased.

What you need

A business mailbox on Namecheap Private Email or Google Workspace. A personal gmail.com address cannot join.
An app password for that mailbox. You make one in your mail provider's security settings, and you can revoke it there at any time.
SPF, DKIM and DMARC records on your domain. They tell other mail servers that mail from your domain is really yours.

When you connect a mailbox, we check your domain's DNS before we try the app password. If a record is missing, you see a DNS checklist with the exact records to add, and nothing is saved.
