This past year, we’ve spent a lot of time talking about “mobile-first.” As we shared back in February, it’s time we stop thinking of “mobile” as mobile. That’s to say, a “smartphone” is so much more than just a “smart” “phone,” and it is certainly used as much more than a “mobile” device. We are far beyond the first iPhone era. So, why are so many email marketers still treating the iPhone as the “secondary” experience? It’s time we acknowledge that many emails will only be opened on a mobile device.
