What is the part after @ in your email address?
Can you send a mail to yourself to check if you gets it?

Which users are not getting your emails? What is the part after @ in their email address?

Looks like their email is marking your emails as spam
It's not a problem at your end.
You have to tell the receivers to put your email to white list or safe contacts
thank you so very much for your help
