I've built a sheet that generates messages for clients based on certain input data. The message appears in a cell in column B when all the required data has been entered. When a new text value is generated at column B I need this script to be activated:
// This constant is written in column C for rows for which an email
// has been sent successfully.
var EMAIL_SENT = 'EMAIL_SENT';
/**
* Sends non-duplicate emails with data from the current spreadsheet.
*/
function sendEmails2() {
var sheet = SpreadsheetApp.getActiveSheet();
var startRow = 2; // First row of data to process
var numRows = sheet.getLastRow(); // Number of rows to process
// Fetch the range of cells
var dataRange = sheet.getRange(startRow, 1, numRows, 3);
// Fetch values for each row in the Range.
var data = dataRange.getValues();
for (var i = 0; i < data.length; ++i) {
var row = data[i];
var emailAddress = row[0]; // First column
var message = row[1]; // Second column
var emailSent = row[2]; // Third column
if (emailSent != EMAIL_SENT) { // Prevents sending duplicates
var subject = 'Cognitive Training Software Tailored To Your Audience';
MailApp.sendEmail(emailAddress, subject, message);
sheet.getRange(startRow + i, 3).setValue(EMAIL_SENT);
// Make sure the cell is updated right away in case the script is interrupted
SpreadsheetApp.flush();
}
}
}
I'm new to any sort of coding and could't figure out how to make this happen. I tried creating an installable trigger using onEdit but could no longer get anything to send.
