Issue:

There are many issues in your code, including undefined variables (eg column , i ), but I think you want to do the following:

Send an email for each row in Sheet1 , taking into account that:

• recipient is in column A .
• subject is based on the value of column C .
• The message body is built by replacing the keywords {name} and {class} from a string template found in Template!A1 with the values of column B and C respectively.

Code snippet:

If the above is correct, you can do the following:

function yourFunction() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheet1 = ss.getSheetByName("Sheet1");
  var firstRow = 2;
  var numRows = sheet1.getLastRow() - firstRow + 1; 
  var templateText = ss.getSheetByName("Template").getRange(1,1).getValue();
  var values = sheet1.getRange(firstRow,1,numRows,3).getValues(); // Retrieve data from all rows
  values.forEach(row => { // Iterate through each row
    var [currentEmail, currentName, currentClass] = row; // Get values from columns A-C
    var messageBody = templateText.replace("{name}",currentName)
                                  .replace("{class}",currentClass);
    var subjectLine = "Reminder:" + currentClass + " Upcoming Class";
    MailApp.sendEmail(currentEmail,subjectLine,messageBody);
  });
}
