How can i say if email not contain @ and .com stop registration

how can do if email not contain @ and .com call notified

You can do that with RegEx:

Just use this block:

PS: Not all emails has “.com” in them
An email can be “.org”, “.net”, etc. I believe, if you don’t want to allow only .com domains, the best choice is check if the domain has @ and if after the @ there is a “.”
Because emails must have this format: @. where the kind of domain may be a hundred of things others than “.com”
