WARM-UP

Mailboxes that are ready before they are used.

New mailboxes join a shared warm-up network, exchange real conversations, and have their daily cap raised only while bounces and complaints stay low. Network-only mailboxes never send a campaign.

  • A shared network, not a mailbox talking to itself
  • Caps rise on evidence
  • Placement watched, rested when it slips

The network

Mailboxes across firms exchange real conversations. Network-only mailboxes exist for warm-up and never send a campaign.

The cap

A mailbox's daily cap rises only while bounces and complaints stay low. It does not rise on a timer.

Rest rules

Placement is tested with seed inboxes. When placement slips, the mailbox is rested. You can also set rules on hard-bounce rate, complaint rate, placement and blocklists.
