Email Set Up
This is best done on a laptop or a PC, not on a phone.
How this works:
Your email service (such as GMail or iCloud) has a feature called "filters" or "rules" that allow you to automatically forward emails to a different address, while keeping a copy of the original email.
You will set up a filter or rule for each of the accounts that send you email you want to process (like a teacher's account or a school account). Set up a filter rule to automatically forward email from those accounts to email@example.com.
