If you want to vote by mail please do so as soon as you can and consider dropping it off at the counter where they will postmark it right away.
Also if you live in a state where you’re allowed to photograph your ballot consider doing so to have proof you voted a certain way.
Note that as a counterpoint the federal register website claims they are just clarifying language to improve public understanding: https://www.federalregister.gov/documents/2025/08/12/2025-15266/postmarks-and-postal-possession

Even then you have to request it. The term you need to ask for is “hand canceling”. The USPS worker will take a handheld ink stamp and mark over the postage stamp with the received date. That letter is now “processed” as received by the post office.
