How to send an email in google sheets if certain conditions exist

  • Reference -

    If you don't mind me asking for help, I need to send an email if certain conditions exist within a google sheet:


    Cell A1 contains a location for a meeting: "Room 202"

    Cell A2 contains a room capacity number, i.e. "50"

    Cell A5 contains the sum total of reservations received for a 4:00pm meeting = "30"

    Cell A6 contains the sum total of reservations received for a 6:30pm meeting = "60"

    4:00pm is fine, but 6:30pm is overbooked.

    My email must go to [email protected] and state that "the 6:30pm meeting in Room 202 is overbooked".

    Can you give me some direction please--thank you.

    @jrenforth Something like this should work assuming that timings are in B column (B5 and B6 in this case)

    function conditionalMail(){
    var sheet = SpreadsheetApp.getActiveSheet();
    var maxBookings = sheet.getRange("A2").getValue();
    var roomNum = sheet.getRange("A1").getValue();
    var range = sheet.getRange("A5:B6");
    var bookingData = range.getValues();
    for (i in bookingData) {
      var row = bookingData[i]
      var bookingsCount = row[0];
      var timing = row[1];
      if (bookingsCount > maxBookings) {
          MailApp.sendEmail("[email protected]","Overbooked rooms","The " + timing + " meeting in " + roomNum + " is overbooked"); 

  • This seems to run and complete, but the email message never arrives.

    Is the email delivering late or it isn't coming at all?
