The Claimable Daily is a daily email sent around 8 am, to anyone in your team who has tasks assigned to them. The Claimable Daily gives you a convenient overview of the tasks due on the day and a heads-up for tomorrow.
​
In order to start receiving it you just need to create tasks in the Claim Checklist. Once you have created a task, just click on it in order to add a Due Date and an Assigned To.

Also, make sure you have the Claimable Daily notification preference enabled, under your profile notifications settings.
