How to delete all email addresses with a specific domain in OS X Contacts using AppleScript?

Question

I have a bunch of email addresses in my contacts that are the email addresses of their phone number provided to them from Verizon.

For example:

1234567890@vtext.com or 

I want to create an Applescript that deletes all of those email addresses.

Answer 1

I haven't tried pbell's answer, but the script below worked for me.

tell application "Contacts"
    tell every person
        delete (every email whose value contains "vtext.com")
    end tell
    save
end tell
