Yes, I agree with you that the additional convenience leads can help with turnout, which is a specially important thing these days.

However, here in Brazil I am convinced that vote-by-mail would only exacerbate the widespread vote-coercion problems we already have in areas that are dominated by drug traffickers or paramilitary groups.

(While we are at it, there are lots of other factors other than vote-by-mail that affect voter turnout and voter disenfranchisement. Certainly one of the biggest ones is that the US elections do not take place on a national holiday, and that there can be a lot of bureaucracy involved in registering as a voter)
