Under Validity's Certification program, your certified IPs must have measurable and consistent volume. Here's what that means:
IP address requirements
- Measurable volume: You must send 100 email messages to Microsoft in a 30-day period from each certified IP address.
- The number of certified IP addresses should be relative to the volume they send.
- IPs without measurable volume will be suspended after 30 days and removed from Certification after 60 days.
- Consistent volume: You must consistently use certified IP addresses for at least 60 days.
- IP addresses with zero sending volume present security issues.
Validity can only effectively monitor IPs sending measurable volume.
