Quick answer
Check Spam, Junk, and Promotions, then search for Openbox and use the newest message. Optional learning emails include a secure link for changing your email choices.
What to do
Check Spam, Junk, Promotions, and any organization quarantine folder.
Search your mailbox for Openbox and the subject of the expected message.
Use only the newest sign-in, verification, or email-preferences link because older secure links can expire.
For optional learning notifications, open the email-choices link in a message you received and save the choices you want.
If messages still do not arrive
Confirm the account email shown in Openbox, allow messages from support@openboxlearn.com, and request one new message. Required account and security messages are separate from optional learning notifications.
