When you Save a Filter you can set up hourly, daily, or weekly notifications for new results.
In Mouseflow, select Add filters to begin customizing your notification report. Once you have selected the appropriate filters to identify the desired segment, click the blue save icon as shown below:
Then name your notification/filter and set the frequency to your preferred time frame for notifications of this report.
Note: For testing, it's recommended to create a Saved View for any filter combination that frequently yields results (e.g. desktop users) and then the "hourly" frequency to get results quickly.
