Recently I wrote a blog post about how LinkedIn email notifications work, and as part of that pointed out that there is no easy way to unsubscribe from invitations. Instead, people who never want to hear from LinkedIn can contact LinkedIn support to request to have their email addresses to their “do not contact” list.
Today I can confirm that this appears to work – look at the screenshot below. I received this email to all the Kabissa role mailboxes that really should never get LinkedIn invitations and that I asked to be added to the list. One interesting side effect of doing this is that if in future you do ever want to join and use LinkedIn using that address you have to contact them again to ask that they take your address off the list.
This is clunky and strange functionality, if you ask me.
