Data Privacy Manager sends email through multiple service providers for both redundancy and maximum coverage. It is recommended that customers whitelist the domain @oncentrl.com for all emails. This will ensure that all emails are delivered.
Data Privacy Manager does not maintain a list of IP addresses that should be white-listed as these IP addresses change periodically. If a list of whitelisted IP addresses must be used, customers should automate the query of the Data Privacy Manager's SPF record. Data Privacy Manager's SPF record maintains the most accurate list of Data Privacy Manager's email IP addresses.
