Here's what to do when your students aren't getting the reminder emails for class!
If your student is using Gmail:
Add email@example.com to your contacts: Google will usually deliver email from addresses that are in your Contacts.
Mark messages as NOT SPAM:
In Gmail, go to the spam folder.
Search for emails containing firstname.lastname@example.org
Select all the emails shown.
Click More and then Not Spam.
If your student is using Outlook.com
Add email@example.com to your Outlook contacts.
Add the address to your safe senders
Click the settings icon in the top-right corner and then More mail settings
Select Safe and blocked senders and then Safe senders
Then add firstname.lastname@example.org to the list of Safe senders
Return to Safe and blocked senders and then select Safe mailing lists
Add the email@example.com to the list of Safe mailing lists
