Self mailer checks unlimited

A self-mailer is a type of mailpiece that can be mailed without the need for an envelope. It's a single sheet of paper or cardstock that contains the message, advertisement, or information, and is designed to be folded and mailed as is.

Here are some benefits of using self-mailers:

  1. Cost-effective: Self-mailers are often less expensive than traditional mailpieces, as they don't require envelopes or postage stamps.
  2. Increased visibility: Self-mailers can be designed to stand out in a crowded mailbox, making them more likely to be noticed and read.
  3. Flexibility: Self-mailers can be used for a wide range of purposes, including advertising, promotions, newsletters, and more.
  4. Environmentally friendly: Self-mailers can help reduce waste and minimize the use of paper and other materials.

Now, about the "unlimited" part...

In the United States, the United States Postal Service (USPS) has specific regulations regarding self-mailers. According to the USPS, self-mailers are considered "flat mail" and are subject to certain size and weight restrictions.

Here are some key guidelines:

  1. Size: Self-mailers must be no larger than 6.125 inches x 11.5 inches (15.5 cm x 29.2 cm).
  2. Weight: Self-mailers must weigh no more than 3.3 ounces (93 grams).
  3. Content: Self-mailers can contain text, images, and other content, but must not include any hazardous materials, flammable liquids, or other prohibited items.

As long as your self-mailer meets these guidelines, you can mail it without any additional postage or envelopes. However, if your self-mailer exceeds these limits, you'll need to use a larger envelope or package and pay the corresponding postage.

I hope that helps!
