I've had the impression for a while that I don't get an email when a page I'm watching is edited. Now I (think I) got proof, since I edited with my volunteer account 2 pages I follow with my staff one. I got an email for the first page but not for the second.
I edited WP:Richieste_tecniche and WP:Malfunzionamenti. The latter correctly triggered an email at 9:01 PM. The former never did.
https://it.wikipedia.org/w/index.php?title=Wikipedia%3ARichieste_tecniche&type=revision&diff=88738962&oldid=88666367 is the last edit that triggered an email for me, I edited that page with staff account afterwards, no other emails.
