Depending on your budget, you may want to have some postcards printed up to send to everyone on your mailing list. You can also ask everyone affiliated with your organization or event to send postcards to their own contacts, too. The advantage of a postcard is that when it arrives by mail people can immediately turn it over and absorb the information. Many people let their mail sit for days and weeks and then open everything at once, so if you send an 8 ½ by 10 flier in an envelope, it may sit on someone’s desk for a long time.
Postage for postcards is cheaper than for letters, and you don’t have to factor in the time and labor of stuffing envelopes. Ask the post office about a bulk-mailing permit.
If you cannot afford a printer, you can buy blank-stamped postcards from the post office and photocopy them or run them through the computer. Also, card stock is available at stationery stores.
