What Is Email WarmUp?
Email WarmUp improves your sender reputation by:
- Sending emails between 100,000+ active addresses in the warmup pool network
- Replying to emails from each other
- Moving emails from spam to inbox

Hide WarmUp Emails
Recommended: Create filters in your email client to automatically archive or hide WarmUp emails.
Not Recommended: Disable Email WarmUp in Email Senders → WarmUp Settings. This stops reputation building for your domain.
