Sending scheduled emails and backing up SQL with MySQL!

Good evening... Despite my research, I couldn't find any sources on this topic, so I would like to consult with you; How can we implement the application mentioned in the title? * Is there a system in Phpmyadmin that allows us to do this? * Does Cron work for this? * Is there a php script that can do this / is it possible to create one? I would appreciate any contribution you can make to the topic, thank you...
