What is Warmbox?
Warmbox warms up email inboxes by simulating healthy sending activity. It sends and interacts with messages inside a network, so your mailbox builds a track record before and during real campaigns.

Key features

- Flexible warm-up modes – growth, flat or random schedules, plus fully custom options.
- Spam score monitoring – track how your mailbox is perceived over time.
- Live email checker – DNS and blacklist checks help you spot setup issues.
- Wide inbox support – Gmail, Outlook, Yahoo, iCloud, Zoho, SMTP and others.
- Agency support – multi-account management and team members.
