The process involves designing the components - front panel, back panel, and the flap. Make sure to include the recipient's address on the front panel, usually 1/4 inch from the bottom. On the back panel, add your return address in a similarly sized box.

Designing with Colors and Fonts

Choose vibrant, easy-to-read colors to catch the eye and convey your message. For instance, warmer colors like red or orange can evoke an urgent or exciting tone, while cooler colors like blue or green are often associated with calmness.

Your font should be neither too small nor too large, ideally between 10-14 point size. Use clear, easy-to-read fonts like Arial, Times New Roman, or Calibri to improve your mail's readability.

Pens, Stamps, and Other USPS Suggestions

Leverage the importance of stamps to set the right tone. Consider using themes that align with your mail's purpose or season, such as Christmas stamps for holiday invites.

Finally, don't overlook the need for proper addressing and legibility. According to USPS guidelines, addresses should be printed in all capital letters, about 1/4 inch from the bottom of the envelope.
