MailApp.sendEmail() in Google Apps Script not send

Question

We establish Google G Suite for our clients and over the last few weeks, we have found that Google Apps Script does not process the MailApp.sendEmail() as expected. It only happens in new G Suite account and the exact same code in existing account function as expected.

function testemail(){
  MailApp.sendEmail("gordon@........", "TEST", "Hello world");
  return;
}

Email address that we have used are valid email.

Any ideas?

Answer 1

Try using GmailApp.sendEmail()

// The code below will send an email with the current date and time.
var now = new Date();
GmailApp.sendEmail("[e-mail]", "current time", "The time is: " + now.toString());

which is the recommended one now.
