I have a survey form that people submit the hours they work and it sends their response in an email to me and then CC's two other people. The script was authorized by me to send the emails and has worked fine for a long time until a couple days ago when now I am getting a reply back from all three emails saying Message blocked. Any idea why these are being blocked?
MailApp.sendEmail("myemail@gmail.com",emailSubject,"", {htmlBody: body, cc: "anotheremail@gmail.com, thirdemail@gmail.com"});
If I only send the email to myself then it works perfectly fine. If I include even one CC email address I get the block.
