Should we be mentioning vote-by-mail in our letters?

No. Please refrain from trying to describe electoral processes or rules in the handwritten parts of your “please vote” letters. Each state has its own election framework, and as we saw in 2020, these policies are subject to change. It’s much better to err on the side of caution rather than providing what could become outdated or incorrect information. Stick to nonpartisan messages about voting, and please refrain from giving advice on how to do so.
