There’s a company spamming domain registrants in an effort to rip them off with a service they do not need called a
Domain name search engine registration
The subject of the email should say something like this:
Domain Notification: YOUR NAME This is your Final Notice of Domain Listing – DOMAIN
This is NOT your domain registration. At the bottom of the email they provide the real details of what this is:
By accepting this offer, you agree not to hold DS liable for any part. Note that THIS IS NOT A BILL. This is a solicitation.
Actually, it’s more like a scam, since it is a service that nobody needs. Would recommend that you toss the email, and definitely do not pay them.
