What Post Cards have worked for you?

[Bailey Rentz]

Hi everyone!  

Working on a new batch of post cards to mail out, and I was just curious are there any post cards you've sent before that you had more success with than others?  For instance, what sort of phrasing did you use, colors, yellow letters, more/less wordy, etc.

I am in the DFW market.  If you don't want to share your secrets I understand!
