Understanding Email Warmup
Why Warm Up Your Email Domain?
Email warmup is the process of gradually increasing your sending volume to build a positive
reputation with email providers. This helps:
- Avoid spam filters and improve deliverability
- Build trust with ISPs (Gmail, Outlook, Yahoo, etc.)
- Establish consistent sending patterns
- Improve inbox placement rates
Key Factors Affecting Warmup:
Domain Factors
- Domain age and history
- Previous sending reputation
- SPF, DKIM, and DMARC configuration
- Domain authentication
Engagement Factors
- Open rates and click-through rates
- Spam complaint rates
- Bounce rates
- List quality and targeting
💡 Pro Tip:
Start with your most engaged subscribers and gradually expand to colder audiences.
Monitor metrics daily and be prepared to slow down if engagement drops.
