Timeshift weekly cron emails

I recently installed timeshift and set it to backup weekly. However, when I looked in /etc/cron.d, I only found timeshift-hourly which ran: 0 * * * * root timeshift --check --scripted which appears to check with timeshift if a backup is schedule and if so, do it. However, I would like to set a cron email for every time I backup and I'm guessing that if I set if for timeshift-hourly, then I will get an email every time that it checks every hour. How would I be able to set a cron email for every time that timeshift does a backup and not every time it checks to see if it's time to backup?
