This is a good post JJ Inc (sans the links
). Worth being discussed. Another tip for online marketers is that, send them post cards or ecards and no not from those annoying sites that sell your addy but its easy for you to upload an ecard script, send them one saying "you can do it" or something if it's for weight loss or something..seems to work really well.
Go out of your way to care for them and they'll do the same for you.
Same with scanning a handwritten note and uploading it or attaching it to an email...
