[Email] Subject Line Checker Launch

View the full email here.

Here's the email design for our Subject Line Checker, which helps you preview your subject line and preview text in 15+ popular email clients. I mirrored one of our product page designs for the email.

For WebKit rendering email clients, we enhanced to an HTML5 video preview (no sound) that on hover showed a "click for sound" CTA that brought users directly into the product with an in-app modal that played the full product video. It's a way of us experimenting to entice users to get into the product quicker and educate them more about the feature. We've only used this on two emails so far and we need more data on how it performs to determine if this is an effective strategy or not.
