This scam presents you with an email that looks much like an invoice indicating that if your domain name is not renewed by a certain date it will expire.
Here's a copy of what the scam email looks like:
However, if you read the fine print at the bottom of the email it states that its not actually an invoice and that you do not have to pay it, its just an invitation to renew your domain through their services, as opposed to your current registrar.
Conetix suggests that you read all emails carefully and if the provider is known to be a scammer then delete them immediately.
Please feel free to forward your correspondence through to Conetix if you believe it's a scam and one of our support staff will help confirm if this is a scam or not..
