Imessage

With iMessages, you can receive messages both on your phone number and on your Apple ID email - or if you have added other emails.

You can see which phone numbers and e-mails you can be contacted at here:

Settings → Messages → Send & Receive

Under "You can receive iMessages to and reply from" remove the checkmarks from your email address(es).

Alternatively, you can block the numbers from which you do not want to receive messages.

What do you mean by “bad messages”.Are they not going through?

If they are coming from the file apps and seem a little shady and off brand,dont reply to them,they are probally scammers trying to scam you

Nice🙂

You're welcome.

Perfect. Hopefully that will do the trick to get rid of annoying messages.
