Background: we are using a custom un-subscription center through a page running on external SF platform and all opt outs goes directly in to that master SF system. From marketing(SFMC) perspective, we can include this custom link in all commercial emails (so far good!!), But facing a challenge to understand how can handle the another standard list-unsubscribe header that appears in email clients gmail or IOS etc. which marketing cloud platform adds for any commercials emails(using send classification comm)
Problem statement: what are the possibilities to handle this deviation behavior(list-unsubscribe one) as its quite common use-case to have custom unsubs center?
what are the recommended / best practices ?
Get this option disabled by contacting marketing cloud support team Or possibility to replace this link with custom url but i read sfmc doesn't http option only 'mailto' so i think woudnt be an option
Rather use transactional send classification for commercials emails rand include custom link in all emails to surface option to customer to opt out.
Handle this unsubscribe response via reply to address set up RMM thinggi.
appreciate much support !!Thanks!
