Warmup Best Practices

  • • Never skip warmup. Sending 30+ emails/day from a new mailbox will get you flagged immediately.
  • • Monitor bounces daily. If bounce rate exceeds 5%, reduce volume and investigate.
  • • Use warmup tools that send and reply to real emails — not just inbox placement tests.
  • • coldBirds automates this entirely with 3-tier warmup cascade and 11 configurable parameters per mailbox.

coldBirds' 3-tier warmup cascade warms mailboxes automatically with proven settings. No schedule needed. No manual tracking.
