Gmail has recently been sending Forum emails directly to spam. Here is how to fix it:

In the Gmail desktop client (not the mobile app), click on the Gear (cog) Setting icon on the top right. Then click "See All Settings" immediately below.

Click on "Filters and Blocked Addresses" at the top middle of the page.  Scroll all the way down and click on "Create a new filter" in the middle.

Enter @scarsdaleforum.com in the From box. Then click Create Filter. On the next page, select "Never send it to spam" and hit Create Filter again.

Forum emails will now always show up in your inbox on your desktop and mobile devices.
