PMs not sending email alerts anymore?

[Late Apex]

I have the box checked to receive emails when I get PMs and it worked last week but after getting PMs this week no emails were sent. I checked my email under settings and its still correct and have made no changes. Any thoughts?

Click "Settings" in the top right corner.
Then "General Settings" in the left column and match everything in yellow.
See if this helps.

Many thanks as I did not have the default thread subscription mode selected to instantly using email. All the other boxes were already set as you show. Ahh well done as it works now !!
