I get over 100 relevant emails a day… I know that's a bit disturbing. It's especially disturbing when the email really isn't that relevant. Such is the case with these LinkedIn emails that tell me about the folks in my network that have changed job titles. I can't help but scan through the faces and click-through to check out what's going on with these folks and their careers. I'm pretty sure this LinkedIn email has one of the highest click-through rates in the email industry.
I get emails all day long from social networks with the names and status changes of people within them, but I rarely dig deeper. When there's a photo, though, I'm immediately mesmerized and have to click through. It makes me wonder… have you seen any statistics on CTRs of emails with photos (not stock photos) of people? My guess is that if you put a real face in your emails, you'll probably get real results.
