Huh. I have three current threads I'm watching via the "track thread" feature:
"In Neptune's Realm - IC"
"In Npetune's Realm - OOC"
"In Npetune's Realm - Chargen and Recruitment"
Curiously, though, despite there being activity and my preferences set to delayed email notification for each thread, I never get notified when there's actvity in these threads.
For reference: I use gmail. I've checked the spam folder, nothing there. If they're being sent, they're not arriving.
