USPS Priority Mail is another excellent option for sending 9x12 envelopes. It offers a flat rate, meaning the postage price remains the same regardless of the envelope's weight - as long as it fits the size restriction. As of 2021, the Priority Mail Retail rate for a 9x12 envelope is $7.80, while the Commercial rate is $7.20.
