It is a great personalized marketing product. Just think about it - when you receive a greeting card in you mailbox - do you usually throw that in the trash. No!! Correct. You will at least open and look at it and will keep it aside. It makes a very personalized impact on you. Send one on special holidays like Thanksgiving or Christmas to your top clients or prospects. If required enclose a gift card (e.g. Starbucks, Amazon) as a thank you token for the business.
