consider adding a fail safe

[laijasmine]

If we will be sending more than x initial emails, should we consider stopping the code, alerting the team in #awardsbot and ask the user to verify and run the code manually? Ie. have an argument in the main function that overrides this.

Looking at previous history I wouldn't expect any more than 10 initial emails a day or 20 reminder emails.

This will hopefully allow for some human intervention and sanity checking prior to a large update.
