Temporary suspension due to exceeding compliance threshold
Validity Certification uses a 30 day rolling average over numerous data points to check for Certification compliance. A large decrease in inbox placement is not expected when temporarily exceeding a compliance threshold, causing a Certification suspension. Our thresholds are stringent and senders aren’t going from a good sender to a bad sender overnight.
IP addresses and domains that are temporarily suspended due to exceeding a threshold might see some minor decreases in inbox placement, depending on the severity of the issues causing the suspension. But, senders with a good sending reputation and a history in the Certification program often retain good inbox placement in the short term due to an increased trust level with participating mailbox providers.
Consistent Certification suspensions
Consistent Certification suspensions over time can lead to filtered or blocked email since factors such as high complaint rates and hitting spam traps impact your sending reputation. If your email program is not adhering to best practices and your sending metrics are consistently exceeding acceptable thresholds, your email may be filtered or blocked, regardless of your Certification status.
Blocklist or security compromise
A suspended IP address or domain may lead to immediate filtered or blocked email if the reason for the suspension was due to a blocklisting or security compromise. Blocklistings and security compromises alone can lead to deliverability problems because mailbox providers using the blocklist or detecting spam like traffic from your IP address or domain will filter or block your email to protect their customers.
