The Winter ’15 release from Salesforce has resulted in a noticeable increase in email alerts. After some investigation, we discovered a new option was added under Reminders & Alerts. If you have noticed more task alerts in your inbox and want to stop these emails, here is what you can do.
Step 1: Locate your User Name in the upper right corner and click the drop down arrow.
Step 2: Click on My Settings
Step 3: Located on the left side of the page, click on Calendar & Reminders
Step 4: Click Reminders & Alerts
Step 5: Uncheck the box “email me when someone assigns me a task”
Step 6: Click Save.
