Two weeks ago I ran into a friend that gave me the push to actually try it. So I outsourced the redesign to a super reputable firm that tested it under every email client (known to man) and I tried it.
What do you know, 397% increase in clicks and a 476% increase in sales average over the last 2 I sent. Usually I initially see a big lift (like this) and then it settles down over time. With those kinds of results, it's obvious users get use to the same old, same old.
My question is how often do you guys redesign your HTML and/or text email templates for a list you regularly send to? Obviously I'm not talking sales pitch emails, just regular weekly mails for updates or newsletter purposes.
