Mailgun Contract Renewal 'Note: Published for completeness, see description for details.'

"Mailgun is an email validation service that provides the following: • Role-based Address Check - For all validation requests, we provide whether an address is a "role-based address". These addresses are typically distribution lists with a much higher complaint rate since unsuspecting users who are part of the list can receive a message they were not expecting. • Disposable Mailbox Detection - Disposable mailboxes are commonly used for fraudulent purposes. We'll tell you whether the address is on a known disposable mailbox provider, and you can choose how to proceed based on your own risk decisions."
