Can you mail a bubble envelope with postage stamps

In the United States, the answer is generally no, you cannot mail a bubble envelope with postage stamps. Here's why:

• The United States Postal Service (USPS) requires that all mailpieces, including bubble envelopes, have a valid postage affixed to them.
• Postage stamps are not sufficient for mailing bubble envelopes because they are not designed to be used on larger, thicker envelopes like bubble envelopes.
• Bubble envelopes are considered "flat rate" mailpieces, which require a specific type of postage, such as a Forever Stamp or a Flat Rate Envelope stamp.
• Using postage stamps on a bubble envelope may not provide enough postage to cover the cost of mailing, and the envelope may be returned to the sender or not delivered.

Instead, you can use one of the following options to mail a bubble envelope:

1. A Forever Stamp: You can use a Forever Stamp on a bubble envelope, but you'll need to use multiple stamps depending on the weight and size of the envelope.
2. Flat Rate Envelope stamp: The USPS offers a Flat Rate Envelope stamp that can be used on bubble envelopes up to 1 oz. This stamp costs $7.50 and provides free shipping to most US addresses.
3. Calculated Postage: You can calculate the postage needed for your bubble envelope using the USPS Postage Calculator tool. This will give you the exact amount of postage required based on the weight and size of the envelope.
4. Priority Mail: If you need to mail a bubble envelope quickly, you can use Priority Mail, which requires a specific type of postage and a tracking number.

Remember to always check the USPS website or consult with a postal worker if you're unsure about the correct postage for your bubble envelope.
