Windmill.dev can do that easily. You can set a cron schedule to trigger a flow that does exactly what you want. If you are not a programmer, you can pick scripts (steps of the flow) from existing list Windmill Hub library (example to send an email) and use AI for the code of your actual business logic (the database part). Apart from that, you don't have to worry about code and maintenance.
It's self-hostable or for less than 1k executions per month, you can use the cloud version for free.
