Hi Zouzi,
If they are going into your spam folder in your
email, then you can change that. Depending on what
email you use, you should be able to either right click on the name of the sender, and mark it as not spam, or do that near the top of the actual email. You can search Help in your email.
You can also add "***@****" to your contact list to ensure they won't go to spam.
If you are getting them, but they are going to spam, that's a setting in your email.
