Mailapp Not Sending With Large Number Of Recipients

My code takes an input of emails that looks like this: email1@gmail.com, email2@gmail.com, email3@gmail.com ... and tries to send them an email using the following code. It seem

Solution 1:

You are not allowed to sent an email to more than 50 recipients at a time.

Number of recipients per email is part of Quotas for Google Services.

You are only allowed to sent an email with a maximum number of 50 recipients.

An obvious workaround would be to split the recipients into two or more (depending upon the number of recipients) different emails so this hard limitation won't be violated.
