Bulk mailing requirements

Bulk mailing, also known as bulk mail or mass mailing, refers to the sending of large quantities of mail pieces, such as letters, postcards, or packages, to a large number of recipients. To qualify for bulk mailing rates, you must meet certain requirements set by the United States Postal Service (USPS). Here are the bulk mailing requirements:

1. Minimum quantity: You must send at least 200 pieces of mail to qualify for bulk mailing rates.
2. Weight: The total weight of the mail pieces must be at least 1 pound (16 ounces).
3. Size: The mail pieces must be at least 3.5 inches long, 6.125 inches high, and 0.007 inches thick.
4. Shape: The mail pieces must be rectangular in shape, with a maximum length of 15 inches and a maximum height of 12 inches.
5. Addressing: The mail pieces must be addressed to a specific recipient, with a valid street address, city, state, and ZIP code.
6. Barcodes: The mail pieces must have a barcode on the address side, which is used to sort and track the mail.
7. Postage: You must affix the correct postage on each mail piece, based on the weight and size of the piece.
8. Mailing list: You must have a mailing list that is accurate and up-to-date, with the correct addresses and contact information for each recipient.
9. Content: The content of the mail pieces must comply with USPS regulations, including restrictions on commercial speech, political advertising, and unsolicited mail.
10. Certification: You must certify that the mail pieces comply with USPS regulations and that you have the right to mail the pieces to the recipients.

To take advantage of bulk mailing rates, you must also use a specific type of mailpiece, such as:

• Standard Mail: This is the most common type of bulk mail, used for letters, postcards, and flats (large envelopes).
• Package Services: This type of bulk mail is used for packages, including boxes, tubes, and irregularly shaped items.
• Media Mail: This type of bulk mail is used for sending books, CDs, DVDs, and other media items.

To prepare your bulk mail for mailing, you will need to:

• Sort the mail pieces by ZIP code or carrier route
• Use a mail sorting machine or a manual sorting system to sort the mail
• Affix the correct postage on each mail piece
• Use a barcode sorter to apply barcodes to the mail pieces
• Seal the mail pieces in a bag or envelope to prevent damage during transit

It's a good idea to consult with a bulk mail expert or a USPS representative to ensure that your bulk mail meets all the requirements and to get the best rates and services for your mailings.
