How to automate sending email to users with 70 days inactivity and delete users after 90 days of inactivity?

Hi @linndaa - Welcome to AWS QuickSight community and thanks for posting the question. There is NO out of the box solution exist for your requirement, however you can create a lambda function and using boto3 QuickSight APIs , cloud trails and SNS you can communicate the users ( if they have not used QuickSight for 90 days) via SNS and then for users who do not have any activity for 90 days, you can delete it.

Note - I have not tried this from my end but this is something you can explore using QuickSight APIs
