Inbox Placement Tester

Send a test email to our seed addresses across Gmail, Outlook, Yahoo, and iCloud — then see exactly where it lands: Primary inbox, Promotions, Spam, or Not delivered. Actionable tips per provider.

How it works

  1. Click "Load Seed Addresses" to get our test mailboxes across Gmail, Outlook, Yahoo, and iCloud
  2. Send your test email to ALL seed addresses from your mailbox
  3. Enter your sender email and click "Check Placement" — we'll check where it landed

coldBirds monitors inbox placement across providers every 6 hours for every mailbox — and auto-suspends mailboxes that start hitting spam.
