Before you get started with the shipping feature. Make sure that you have a valid address and payment method added in the Settings page. Here's the article to help with that.

Letter & Flat

Letter and Flat rate packaging does not require official USPS flat rate packaging, but it is still subject to dimension and weight restrictions.

Important Notes

• The GOMdrop price will differ from the retail price due to additional service fees that we use for our third party payment processor.
• Currently, GOMdrop is unable to offer refunds for letter and flat shipments, due to the process being very different than package or flat rate shipments.

Letter

Letters are rectangular envelopes that fall within the following requirements:

• Minimum: 3 1/2 inches x 5 1/2 inches
• Maximum: 6 1/8 inches x 11 1/2 inches
• Must weigh below 3.5 ounces
• Must be less than 1/4 inch thick
• Must be machinable: i.e. flexible enough to go through sorting equipment.

If you generate a letter rate with a package that is greater than 3.5 ounces, your rates will only show Priority rates.
