Before you send a marketing postcard to print there are many things to consider before pulling the trigger:
Square mailers usually have higher postage rates than rectangular pieces, as they cannot be sorted automatically. There are also three main classes for mailers: true postcard size, letter and flat size. A true postcard can range from 3.5″x5″ to 4.25″x6″ and will have the most cost effective postage and sorting rates. Letter size mailers can range from 4″x6″ up to 6″x11.5″ and flat size mailers can go up to 12″x15″.
Don’t forget that there are rules to follow with layout. There must be clear areas for the postage, address and barcode. There are of course specific requirements for the size and location of these elements.
Depending on the type and size mailer the post office requires a minimum weight. You also need to consider if the stock should be coated or uncoated. If you would like your recipient to mail a reply card, you need to choose an uncoated stock so that the ink does not smear.
