1) FACE FORWARD
Mention Facebook in the subject line (e.g. “Favorites of Facebook Fans”).
2) KEEP IT SUPER SHORT
Use bullets and slash your copy like a serial killer.
Spend 50% of your time on the subject and preview text, other 50% on everything else (including design).
4) MIRROR IMAGE
A landing page that features the same primary image of the email that links to it will generate a higher response rate than one that does not use the image.
5) STUTTER STEP
Repeat yourself on landing pages. It’s redundant, but it gives the recipient the much needed confirmation that they are at the right place.
6) GO ALL-IN
Create “All in” emails, in which every link except the opt-out goes to the same landing page, rather than multiple calls to action.
7) ALL ROADS LEAD TO REV
Use multiple links and links styles, to the same destination/offer.
