Regex: Identify all lines with a string that doesn't have a specific character

I have some text representing a list of email addresses where I would like to regex search for the lines that are missing a @ in the email address.

For example:

email: [email protected]
email: baz.com
email: blah blah blah
name: Steve

I want email: baz.com and email: blah blah blah to be captured.

I know that I can use:

(email: ".*")$ to capture all the lines with email in it.

Is there any way to further narrow down .* with a negative lookahead to exclude those with @ already in it?

You could use /^email: [^@]*$/ to match a string that starts with email: then consists only of characters that aren't @.
