Postcards can be great small promotional pieces - even if they are never meant to be mailed via USPS. Great for cover-flat items, book marks, oversized business cards, trading, rolodex, book plates, and more.

Today, color post cards are also being used instead of full printed catalogs for sample or spotlight item advertising.  They are fast becoming the twenty-first century's handbill. They bridge the gap to drive traffic online from those who still prefer printed notice to those who willingly navigate by smartcode, and still reach outside the virtual world.  They can be used as notices to put on bulletin boards and fit easily in a file-o-fax.  Being on card stock, they are even easier to find than a standard piece of paper in many "desk top jumbles".  Great way to target a single item or detail!

Post cards are fully customizable and are great for all sorts of communication from birth and celebration announcements to meeting notices and deadline reminders.  They are super for informal graduation and marriage notes or inserts and invitations of all kinds.  They are beginning to even take the place of formal thank you and "informal" cards.  Affordable as these cards are, they may be the only stationary item at your correspondence desk that you still haven't considered having personalized.

Special Card Design Note: Be careful in adding your name/address to a postcard design. As both sides of the mail piece are fully viewable and the only notice of which side is "up" is postage, do not place your name and address in a standard addressing format (3 lines roughly center of card) on either side of the card - unless you want the card returned to you. Because of the nature of mailed cards, and automated systems, cards may get "flipped" in the mail stream and returned to you: this acts as a return service, effectively "using" the postage to mail the card to yourself.

They can also be cost effective reply and/or ordering forms.  A post card costs less than a letter to return to you (in both postage and printing), and as a supplied convenience to your customers can cost the same or less than an return slip and  envelope.  This is great for economical RSVPs, "bill me" order forms, pledges, etc.  Event and reunion planners can use these for requests, name tag information, actual tickets, keepsake/commemorative/event merchandise and door prize promotion, donation, freebie and door prize requests, etc.

ID/Privacy note: While post cards are highly versatile and a great economical alternative to many types of physical mailings, one shouldn't plan a post card that requests any information be placed on a provided post card that could lead to identity theft.  While it is a felony to tamper with the US Mail Service, most people that fill out return post cards don't take into consideration protecting cards, such as placing them into envelopes, before they get into the mail stream - especially when return postage is provided on the post card itself.  Alternate suggestions include, instead of blanks to fill in, a check box for "use information on file"; provide a telephone number (reminding person not to use cell or cordless phone) for information verification; etc.  When requesting information be sent back to you, in general, you can ask for anything.  Don't expect a person using a provided postcard to think about protecting there information by placing it into a security envelope, many may simply choose not to provide ID sensitive information.
