Email Summaries are automatic emails with a brief overview of all the updates that have happened in your Arkit projects. You can choose to receive an email summary once a day, once a week or once a month.
You can control what kinds of email Arkit sends you. In Settings, under Email Preferences, you can adjust the frequency of your email summaries, or turn them off. You can also control the settings for real-time emails that Arkit sends for any projects you are watching.
