Using GmailApp and CC more than 100 people

Question

I am using a free AppScript account, when I try to send a message using GmailApp and CC less than 100 people there is no problem, but more than 100 people get the message: Exception: Limit Exceeded: Email Recipients Per Message.

function sendMail(fullname, mailTo, mailCC, subject, image) {
var img = DriveApp.getFileById(image).getAs("image/png");
var logo = {"logo" : img}
GmailApp.sendEmail(mailTo, subject, "", {
cc:     "[email protected],[email protected],[email protected],[email protected],nguyenvan5@gmai    l.com,[email protected],[email protected],[email protected],[email protected],nguyenvan1    [email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected]",
htmlBody: "<p>Hi " + fullname + "</p></br><img src='https://drive.google.com/uc?export=view&id="         + image + "'>"

}); }`

If I upgrade my account, this problem can be solved!

Answer 1

This is a limitation within gmail itself. its not something you can bypass

Gmail sending limits

100 Recipients per message sent via SMTP (by POP or IMAP users) or the Gmail API Addresses in the To, Cc, and Bcc fields of a single email. Includes email sent using smtp-relay.gmail.com or smtp.gmail.com*
