I don't think it was Tom. That sentence starting with "While" is not a complete sentence, which is suspicious because Tom is very precise with his language and is a nerd about grammar (he has made videos about linguistics). There are also a few other questionable grammar choices like the comma after "though" (I think there should either be no comma, or a comma both before and after?) Also, the comma after "thanks and regards" either needs to be followed by an "and" or it should have been replaced by a period or exclamation point.
