The vocative comma use varies with formality. For a good explanation,
see https://www.macmillandictionaryblog.com/hello-vocative-comma -- but the
quick and dirty explanation is that in informal writing it's optional.
IMO, the only time it absolutely must be used (in order to ensure clarity) is
in a
sentence such as "I'm fighting John" which is different from "I'm
fighting, John".

Gmail seems happy to fill in (autofill) text (at least in the Windows
version on a PC). If I address a message to Frank, and begin typing
Hi it writes "Hi Frank", but if I type Hi, it leaves the
text alone. Make of that what you will! :-)

This is called a conjunctive adverb, and the rule seems to be that you
always have a comma after a conjunctive adverb.

The books Ardith and I use most are the 2000 "New Fowler's Modern
English Usage" and the 2016 "Garner's Modern English Usage". Fowler's
tends more toward British usage and Garner seems more American. Here in
Canada, of course, we're bilingual. :-)
