Just because you have a word processing program doesn't make you a poet.
Same thing with a design program. Having good graphic design is more than knowing how to use the software.
And just because you can design a postcard, doesn't mean you can mail it.
Graphic design for direct mail requires understanding a number of criteria:
Not everything that can be designed can be printed. Not everything that can be printed can be mailed.
And if you don't have an offer or message, you may as well burn your money in a parking lot.
Most printers are ignorant of mailing requirements. I have seen many postcards printed that couldn't be mailed.
And printers do not have a marketing background that can help you.
I have stayed in business for over 30 years because I make money for my clients. I know how to design postcards, write copy and get the postcard mailed at the lowest possible postage.
I have heard so many people they tried direct mail marketing and it wasn't effective. I take one look at the piece and I can understand why there was no response.
