- Check spam folder placement with test emails
Important Warmup Guidelines
- Never skip the warmup process, even if you're migrating from another provider
- If bounce rates exceed 2% or spam complaints exceed 0.1%, pause and investigate
- Use email warmup tools alongside manual sending for best results
- After warmup, maintain consistent sending patterns to preserve reputation
Complete Guide to Email Domain Warmup
Email warmup is the process of gradually increasing your sending volume to establish sender reputation with email providers. Without proper warmup, your emails are likely to land in spam folders.
Why Email Warmup Matters
Email providers like Gmail, Outlook, and Yahoo are suspicious of new sending domains. They need to see consistent, positive sending behavior before trusting your emails:
- New domains start with zero reputation: ISPs don't know if you're legitimate or a spammer.
- Sudden volume spikes look suspicious: Spammers often blast from new domains then abandon them.
- Engagement signals build trust: Opens, clicks, and replies tell ISPs your emails are wanted.
The Science Behind Warmup
Email warmup works because it demonstrates to mailbox providers that:
- Your sending patterns are consistent and predictable
- Recipients actually want and engage with your emails
- You're following email best practices (authentication, list hygiene)
- You're not a "hit and run" spammer
Warmup Best Practices
Do
- Start with engaged subscribers
- Increase volume gradually (10-20%/day)
- Maintain consistent send times
- Monitor bounce rates daily
- Use warmup tools alongside manual sends
Don't
- Rush the process
- Send to cold or purchased lists
- Skip weekends or have erratic patterns
- Ignore high bounce/complaint rates
- Stop warmup after a few days
After Warmup: Maintaining Reputation
Completing warmup is just the beginning. To maintain your sender reputation:
- Stay consistent: Don't let your domain go dormant for extended periods.
- Clean your list: Regularly remove bounced and unengaged subscribers.
- Monitor metrics: Watch bounce rates, spam complaints, and placement rates.
- Scale gradually: Even after warmup, increase volume incrementally.
