I live in Oregon where everything is vote-by-mail, and on the whole it works great. Each ballot is basically a generic survey-style scantron form and dead simple to fill out (fill in the circle next to your choice, or next to the blank line and write in a candidate), as of this year no postage is required so the only cost to the voter is a pen or pencil, and voters without a mailing address can register to pick up a ballot at the county elections office and can then drop off that ballot at any post office or in one of the drop boxes at libraries and public squares. It also has overwhelming bipartisan support (>75% among both Democrats and Republicans) and results in turnout well above most of the country (63% in 2018 midterms compared to 49% for the US as a whole).
