Mass nouns get no S
More accurately, a mass noun cannot be assigned a grammatical number. For example, compare
Asterisk means “agrammatical”. #1 shows “bread” is a mass noun, and #2 shows “sheep” isn’t, even if “sheep” doesn’t accept the ⟨s⟩. (It’s just a weird plural.)
…that said I think your take is bad. “Countability” is rather unstable, specially if there’s some semantic pressure to keep both the countable and uncountable meanings. That applies to “mail”; in fact the word used to be only countable. (It meant “bag”. Nowadays that meaning is archaic, but still.) Add dialectal variation (e.g. Indian English speakers seem to be rather fond of using “mail” as a countable noun) and language interference, and the whole thing becomes an “I only accept when people use a language the same way as I do!”.
