Hi there! I understand you'd like to manage or stop receiving alerts or notifications from the Jacquie Lawson Ecards app on your Mac running OS X 10.15.7. Can you tell me a bit more about the alerts you're getting? Are these app notifications, emails, or something else? Also, have you tried any settings changes so far?

Meanwhile, here’s a general guide on managing notifications from Jacquie Lawson Ecards:

1. Open the Jacquie Lawson Ecards app on your Mac.
2. Tap or click on the More option/menu.
3. Select Email Preferences or Email Notifications from the list.
4. From here, you can adjust which types of emails or alerts you receive, turning off anything you do not want.
5. Save your preferences before exiting.

This process stops or limits email notifications, which are the most common alerts users want to manage1 3.

If you are receiving system or push notifications at the Mac OS level, you might also check your Mac’s own notification settings:

- Go to System Preferences > Notifications.
- Find and select Jacquie Lawson Ecards in the app list.
- Adjust alert styles or turn off notifications altogether.

Could you let me know if these alerts are incoming as emails, or directly as notifications on your Mac desktop? That way, I can tailor the steps better for you.
