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
