What is ID Protect and how it works?

At 2MHost.com we take your privacy seriously. That's why we protect your personal information with ID Protect.
When you register your domain name, your personal information is published in the Whois Public Internet Directory which can be viewed by anyone at anytime. This is required by the Internet Corporation for Assigned Names and Numbers (ICANN) as part of the domain name registration process.
Now you have the opportunity to mask your personal information with ID Process. Get Peace of Mind with Private Domain Name Registrationd

But how does this protect us from spammers?

With similar services, the visible email address (for example: gmvjcxkxh@whoisprivacyprotect.com) will forward any emails to registrar email address, so this will not protect you from spam.
But Due to 2MHost's dynamic email system, your visible email address is constantly changing, so while it is being harvested and redistributed, it will change and the previous address will no longer work for the spammer. The Domain Privacy Protection Service secures and maintains your real email address on file so you receive important information regarding your domain.

And how much does this service cost?

With 2MHost this service costs nothing! its free for all 2MHost customers, Almost all other domains and hosting providers charge large fees (if compared with domain registration fees) for it.. take a look:
