You have the option to enable spam filtering for emails . While logged in as an admin:
- Go to Admin and click Email
- Find the email address you want to filter and click the gear icon on its card
- Select Settings from the menu
- In the settings sidebar, toggle on Turn on spam filtering for incoming emails
- Click Save
This will make sure that any email that looks suspicious will be automatically marked as 'Spam'.
Tickets marked as spam can be viewed in the 'Spam' folder for 30 days. If you have issues with missing tickets you can check the spam folder.
