I am running into a problem. I have been blocked form sending emails for the day. Apparently, there is now a quota that I am exceeding? (This has never happened before.) I am receiving this message when trying to send: You have reached your email qouta for the day.
Google gives 1500 emails per day for G Suite Education accounts and 100 emails per day for regular Gmail accounts. This is enforced by Google and reset every 24 hours.
