This approach works very well, except I ran into a problem when I tried to send emails to 30+ students. After approx 25 emails, the remaining emails failed-to-send. When I login to Gmail, the message seems to have bounced back, meaning the message isn't sitting in my Drafts folder, but rather sitting in Inbox as a returned message.
I thought this might be a problem at the recipient's end --- all messages are going to different students with the same domain name.
However, now, when I try to send just a regular email to anyone (not necessarily a student at the same domain name), the account fails to send message.
Obviously, I'm missing something here. Any help would be much appreciated.
- I have given permission within Gmail for "less secure" clients to use my Gmail account.
- I do not have two-factor authentication turned on.
