Evercontact has analyzed over 4.6 billion emails in order to turn email signatures into address book contacts for our customers. Here we take a deep dive into the data we have as it relates to the volume and value of contacts, the surprising rate at which contact info changes, the crazy amount of contacts for our all time best customer, and of course some important + fun stats on email itself (curious about the average thread size of a “reply all”? We got you).
