I have a column which mentions which mentions schedule date and time. I wanted to send email as per scheduled date, does anyone have any idea how I can mentions in my function</p>

<pre><code>+----------------------+---------------+-------------+-------------+

function sendEmails() {
for (k = programFirstRow; k &lt; totalProgramRows + 1; k++)
  {
  var sheet = SpreadsheetApp.getActiveSheet();
  var startRow = 2;  // First row of data to process
  var numRows = 2;   // Number of rows to process
  // Fetch the range of cells A2:B3
  var sendDate = SendSheet.getRange("A"+k).getValues();
  var emailAddress = SendSheet.getRange("B"+k).getValues();
  var Subject = SendSheet.getRange("C"+k).getValues();
  var message = SendSheet.getRange("D"+k).getValues();
  // Fetch values for each row in the Range.
    MailApp.sendEmail(emailAddress, subject, message);
  }
}
