How to work as a greeting card writer
Write on a freelance basis.
For the most part, greeting card companies stockpile their verses and messages through a steady influx of submissions from freelance writers. Do a little investigating to find out which companies accept freelance contributions and send in a few of your most polished samples.
If they like what they see, they'll agree to print it and you'll receive compensation. Card publishers tend to be particular about the way they want things done, so be sure to look up the editorial and submission guidelines for the company you're submitting your work to.
