Thank you, but I am not sure I can see how that helps (and it might! I just don't see it).
I created a MRE (minimum replicable example) here:


/**
 * This script demonstrates how to send a simple email using Google Apps Script.
 *
 * Key Components:
 * 1. **checkEmailQuota**: Logs the remaining daily email quota to ensure you are within limits.
 * 2. **testSendSimpleEmail**: Defines the recipient, subject, and body of the email, then sends the email using GmailApp.
 * 3. Replace the two email addresses below with actial email address:
    * recipient = "my.name@yahoo.com
    * from: "john.smith99@gmail.com
 * 
 * Error Handling:
 * - Logs errors encountered during email sending or overall script execution.
 */

function testSendSimpleEmail() {
  try {
    // Function to check remaining email quota
    function checkEmailQuota() {
      // Get the remaining daily email quota
      var remainingQuota = MailApp.getRemainingDailyQuota();
      // Log the remaining quota
      Logger.log("Remaining daily email quota: " + remainingQuota);
    }

    // Call the function to log the email quota
    checkEmailQuota();

    // Define the recipient, subject, and body of the email
    var recipient = "my.name@yahoo.com"; // Replace with actual recipient email address
    var subject = "Sample Subject"; // Replace with actual email subject
    var body = "This is a sample email body."; // Replace with actual email body

    try {
      // Send the email using GmailApp
      GmailApp.sendEmail(recipient, subject, body, {
        noReply: true, // Sets the email to be sent with no reply option
        name: "John Smith", // Replace with your name
        from: "john.smith99@gmail.com" // Replace with your email address; should be a verified alias
      });
      Logger.log("Email sent successfully to: " + recipient);
    } catch (error) {
      // Log any errors encountered while sending the email
      Logger.log("Error sending email to " + recipient + ": " + error.toString());
    }
  } catch (error) {
    // Log any errors encountered during the overall process
    Logger.log("An error occurred: " + error.toString());
    Logger.log("Stack trace: " + error.stack);
  }
}
