The sub-user I added did not receive the email from JotForm

Hi, on my account I deleted a previous sub-user and have now added a new sub-user.  When I did that (14 hours ago), the pop-up indicated that an email had been sent to the new person.

However, my colleague has not yet received the email, and it is not in their junk mailbox either.   What could be the issue?

Thank you for your assistance.

The invitation has been sent based on our logs. Please ask Loresa, if that's the correct name, to check her spam folder or filtered emails. Since it is sent, the email is likely filtered as spam, so that needs to be marked as not spam to proceed. 

Thanks for your reply, Welvin. It was not in the junk folder, but we managed to get her connected by having her create a fresh JotForm account. The Shared files showed up successfully once she logged in.
Best regards,
