Note: Certification only enforces on its mailbox provider complaint rate thresholds if you receive a set minimum number of complaints.
*Return Path stopped enforcing compliance for AOL on 1/18/19 due to Verizon Media migration, or the consolidation of Yahoo and AOL infrastructures. AOL data will still appear in the Certification user interface and DPR though AOL data will decrease over time until there is no AOL-specific data left to report. You will notice a steady decrease in AOL data alongside a steady increase in Yahoo data.
Here is the list of mailbox providers and the minimum number of complaints you need to receive in order for Certification to enforce its complaint rate thresholds:
- Microsoft: 200 complaints
- Yahoo!: 200 complaints
- Comcast: 100 complaints
- Cloudmark: 100 complaints
