“The debut of the Apple Watch makes it absolutely clear that marketers must continue to not only send multi-part MIME messages containing a plain text alternative, but to optimize that plain text alternative for wearables like the Watch. Also note that special characters, extra spaces, and other formatting tricks reserved for desktop plain text consumption translate very poorly to the Watch’s 38mm screen.”


Depending on your niche of consumers, wearable technology may be an important consideration for how you tackle a successful email campaign. Currently, the Apple Watch does not detect remote or linked images and embedded images have poor support. Instead, plain text messages work best but should be tested using wearables if they’re available to you.
