Should I block emails from spamgourmet.com?
Yes. spamgourmet.com is identified as a disposable email service. Users signing up with it usually want to avoid giving a real address — expect high bounce rates and throwaway accounts.
One GET request tells you if any email address is disposable, an alias, or undeliverable — before it hits your database.
