For Business Sake: Dump the Freemail Service!
Recently, one of our clients was victimized in a phishing scam. She got an email from someone claiming to be from MSN Hotmail, saying they were going to close her account in 48 hours unless she was able to provide her email address, password and birthdate. They stole her hotmail account: They changed all her secret questions and birthdate. Then she locked out of her account. Now, we’re working hard to get it back from scammers who wile away their time, emailing her business associates, family and friends, begging for money on ”her” behalf: ”I’m in London and I lost my wallet! Please wire money to…” She was left with nothing. No emails. No email addresses. And no one sending her money to London.
Why did this happen? It could have all been avoided if she had not used an @hotmail.com account for business and personal email and contacts. You should think about dropping your easily obtained address. If you get hacked (and it’s easy to get that way). 
1) you may never get your contacts list back.
2) you may lose your email address permanently.
3) your calendar might disappear with your account.
Also, it’s not terribly professional. If you have a name like @yourcompany.com (I have an email that ends with ”@itmcomputing.com”), it shows you are dedicated to your business and serious about it. If you need to register a domain name – go to one of the hundreds of services our there or go to our service at I Want A Domain Name.com
A registered domain name may cost more than the “free” services but starting over from scratch can cost you a lot more - in business and reputation.
If you just can’t live with out your @gmail.com @hotmail.com @rocketmail.com @yahoo.com email address, please, please change your password NOW.
