My postcard blitz was a flop, but I'm going to do it again.
I've changed my niche & target market. I'm also going to have a special offer. My last cards were sort of educational - "How a VA can help you!" - but I didn't have any incentive for them to call me.
My next cards are going to be cheaper, too. Have you seen how they look after going through the mail?

A slightly lower quality of print will not mar their appearance, I assure you.
For the record, I sent out three separate mailings to the same list of 600, about 6 weeks apart.
