Update: This is now live! 

Please offer the ability in BBIS to switch on/off a setting that supports Gmail's List-unsubscribe functionality (displayed as a prominent unsubscribe link next to the sender name in the inbox). This feature is supported via a a feedback loop between the recipient Mailbox Provider (Gmail) and Blackbaud email service. Feedback loops are already supported in the BBIS architecture, as we see this is evident with SPAM complaint being suppressed from future emailing, but it would be great to also allow list-unsubscribe (where Gmail algorithms rank these emails more highly with inbox placement) as it would improve our overall sender reputation and email deliverability.
