Q: What is IP warm-up and do I need it?
IP warm-up gradually increases sending volume on a new IP address to build reputation with ISPs.
You need it for:
- New dedicated IPs
- IPs idle for 30+ days
- Significantly increased volume
We automate this process over 2-4 weeks.
Q: How do I improve my sender reputation?
- Authenticate your domain (SPF, DKIM, DMARC)
- Send quality content (use content scoring)
- Maintain good list hygiene
- Monitor engagement metrics
- Follow proper IP warm-up schedules
- Maintain steady sending patterns
Q: What should my bounce rate be?
- Good: Below 2%
- Acceptable: 2-5%
- Poor: Above 5%
If your bounce rate exceeds 10%, we may pause sending to protect your reputation.
Q: What should my complaint rate be?
- Good: Below 0.1%
- Acceptable: 0.1-0.5%
- Poor: Above 0.5%
Complaint rates above 1% may result in account suspension.
Q: How do suppression lists work?
Suppression lists prevent sending to addresses that have:
- Hard bounced
- Soft bounced repeatedly
- Complained (marked as spam)
- Unsubscribed
- Been manually added
Automatic suppression happens immediately.
Q: Can I whitelist specific addresses?
Yes, you can whitelist addresses to bypass suppression. Use this carefully for:
- Test accounts
- Internal email addresses
- Verified opt-in addresses only
