Twitter officially launches new weekly ‘people you may know’ email

Twitter has been experimenting with a variety of new email formats to increase engagement and takeup of following on its service. Today, they’re introducing one that they’ve been testing that introduces you to ‘people you may know’ on Twitter

Twitter explains how the people are chosen:

Suggestions are based on signals like who your friends follow and the contact information imported by people you know. For example, if several people you know follow someone, you may also know them and want to follow them too.

Twitter has a unique problem to solve when it comes to encouraging users to engage more. The fact is that Twitter is nothing until you start following people, and the quality and relevance of the people that you follow has a direct bearing on how much you check the service and how much you interact with tweets you see there.

Update: As you can see below, Twitter is now displaying a separate setting for those email notifications.
