Crossbeam sends a rollup of all new partner overlap activity once a day. You can review the summary at-a-glance, and log in to Crossbeam to analyze and take action on new overlaps.
If you'd prefer not to receive daily rollup emails:
Navigate to the "Profile and Preferences" page from the account menu in the upper right corner.
Uncheck the box next to "Daily activity rollup."
Click "Update Notification Preferences" to save your email settings.
Here is a video on managing your notification settings!
