Sharper images for sharper emails

If you’re anything like us, you’re a tech fiend who loves upgrading to all the latest devices. And there’s no denying that their newer, more sophisticated displays are absolutely gorgeous… but they also have an impact on the way we see emails.

You see, retina displays produced over the last few years (including the ones on the iPhone 4S and up, iPad 3, MacBook Pro, and Android devices like the Samsung Galaxy Nexus) are capable of displaying images in a sharper and more vibrant quality than ever before. So images that looked great on your old device can now render blurry, fuzzy, and unfocused.

The reason for the inconsistency is an increase in PPI, the measurement of the number of pixels spread across an inch of screen space. The increase has doubled the pixel ratio of new displays from 1 to 2, so a high-density display now has double the resolution of an older one.

So to optimize for retina displays and eliminate blurry images, we’ve taken the "2X" approach to rendering images in email. Technically speaking, this means rendering images at double the pixel count.

 

…lost? That’s ok – I think I actually blacked out for a second. Here’s the most important thing to take away from this all:

Now, when using an Emma template, simply upload high-resolution versions of your images (1280px wide) to your mailing, and we'll take care of the rest! When the email is sent, your images will automatically be retina-ready in the inbox and look sharp, crisp, and beautiful – no matter what device your subscribers are using to open it.

Cool, huh? If you have any questions about this update, feel free to fire away in the comments! And don’t worry – I’ll pass them along to our developers who actually understand this stuff instead of trying to answer them on my own.
