Land in the inbox,
every time.
WarmupTool runs controlled SMTP warmup cycles between your mailboxes — smart role pairing, real monitoring, and zero spam loops.
By continuing you agree to our Terms and Privacy Policy.
SMTP & IMAP aware
Sender-only mailboxes can skip IMAP. Active receivers validate IMAP so replies and inbox actions stay possible.
Safer pairing
Prefers cross-provider targets when your pool allows it — so Gmail doesn't only talk to Gmail.
Runs on schedule
Trigger cycles from the dashboard or wire a daily cron. Cooldown states back off when reputation dips.
What WarmupTool does
- Connect mailboxes via SMTP/IMAP credentials or Google OAuth for Gmail
- Run controlled warmup cycles with roles: sender, passive receiver, active IMAP receiver
- Monitor sends, replies, and errors in a live activity dashboard
- Optionally draft messages via AI API key, or use built-in templates
Google Sign-In & Gmail access

Public homepage URL (for reviewers)

Google verification expects a domain you can verify in Search Console. Add a custom domain, verify it, set NEXT_PUBLIC_GOOGLE_SITE_VERIFICATION from the HTML tag method, then use that HTTPS URL as the OAuth application home page and privacy policy host.
