I love a/b testing designs and subject lines for email. Today I took a promotional design and adjusted the hierarchy subtly. I'm excited to see how this affects customer engagement.
The original design had "New Markdowns Taken!" as the opening line. In my test I shorteneed this to "New Markdowns!" and also made the font a little smaller.
The original design had a very bold "50% OFF" which I reduced from Bold to Semi-Bold.
Also, the Find A Store button was fairly small, so I enlarged it and also enlarged the CTA text as well as made the "In Store Only" line a little smaller.
