On Wednesday, LinkedIn introduced a product called Intro, which adds a LinkedIn profile directly in the default iOS Mail app. Impossible, right?
Not exactly. It moves all of your email accounts through a proxy which LinkedIn controls. The proxy injects the LinkedIn profile card, and sends it to the default Mail client. Installing it is made possible by way of an iOS configuration profile. Clever, right?
Once you install the Intro app, all of your emails, both sent and received, are transmitted via LinkedIn’s servers. LinkedIn is forcing all your IMAP and SMTP data through their own servers and then analyzing and scraping your emails for data pertaining to… whatever they feel like.
