Are your recruiting emails mobile-friendly? They need to be. If you know me, you know I'm about to back this up with a statistic. (I've never met a research study I didn't like, hat tip to Kelly Dingee for forwarding this one to me).
The good people at Knotice took the trouble to do a composite cross sampling of 500 million emails sent in the last 6 months of 2012. (I'm not entirely sure what all that means, but it sounds like a lot of work.)
41% of emails are opened on a mobile device.
And further, if your recipient does not "...act right away, our data shows only about 2% will reopen that email on another device — whether on their desktop computer, smartphone, or tablet ... This means that even if you created a compelling subject line and delivered the right offer, if it renders poorly on the device or if there isn’t a seamless optimization of the post-click experience, you have missed your window."
