Since our launch in 2011, Evercontact has analyzed over a billion emails to auto-enrich hundreds of thousands of address books, and we’ve had the chance to interact with thousands of wonderful clients. From time to time they ask us big data questions which certainly get us wondering…

What is the average size address book?
 
How many people is the average professional in contact with every month, or the past 6 months?
 
Do they have phone numbers for their contacts?
 
Are most emails in their inbox from real people… or robots!
 
What services help to conquer the inbox and stay on top of their contact management, their leads, their sales?

To answer these questions, we’ve been digging into our data the past few weeks to better understand how people use their address books, and email in general. Below are the fascinating stats we’ve found and we decided to push them out as an infographic, so hope you enjoy, and feel free to leave any questions/comments below! Oh, and, if you’re not already taking advantage of Evercontact to auto-enrich contact details in your address book/CRM, then definitely check it out for Gmail, Google Apps, Outlook, Chrome, Salesforce, Highrise, Evernote and Connectwise (or as an API).
