Notification - keep sending email notification

After changing one of my notifications that I had already added, I noticed that I continued to receive the same notification, as if I had not changed it.
I already deleted that notification and I´m still receiving.

Welcome, Luis!

Could it be you accidentally activated periodic notification?

Thanks for the reply, but the periodic notifications during service problems rule is not active.
I already deleted the rule and create a new one, with out that and I´m still getting the emails.
