Google Sheets: sendEmail() with day exceptions

I was able to send rows from a Google Sheet via e-mail, using the Javascript sendEmail() function. The aforementioned Google Sheet is linked to a Google Form.

In the sheet, under the column "Recursive_Requests", there are 2 options to send data. I would want that:
1) if you select "send_every_day" option, the request is sent by e-mail every day;
2) if you select "send_every_monday", the request remains in the sheet, BUT it is sent only every Monday;
3) if you select "No", no changes are made.

Any help would be appreciated!
