Global Suppression List
Last Updated: Feb 02, 2017 02:13PM EST
SparkPost maintains a Global Suppression List (GSL) applied across all mail streams. The GSL contains a number of common misspelled domains as well role addresses (Mailbox Names for Common Services, Roles and Functions (RFC 2142).
RFC 2142 assigns mailbox names to be used when contacting personnel at an organization. These mailbox names should not be used for marketing, as they are role addresses built for functions, not personal use. For example, abuse@ should be implemented so that individuals can easily send abuse information or complain about spam to a domain holder. Role addresses are vulnerable to be harvested by spammers and therefore sending to them can harm your reputation. Sending to role addresses can cause a rise in spam complaints, blacklisted IPs/Domains and overall delivery issues.
SparkPost automatically blocks you from sending to role accounts because we want to help you achieve the best delivery possible. If you would like more information on what role addresses are suppressed or have a special use case for including certain roles in your mailings please Submit a support request.
