Emails Never Get To Invitees

Every time I set up a meeting and add the invitees to zoom no one ever gets them. Do we need to add a DNS record or something in our domains that allows the emails to be sent from Zoom? 

It's very frustrating to constantly be told nothing is in junk folder and I never received an email.

Using Mac Air M1 latest version of OS and latest version of Zoom. This has been ongoing for 5 years. I feel if I'm going to have to pay for this it should work.
