Want to send urgent emails to your friends but don’t know when they’ll get your message? Then, send your email as a SMS to any of your friend’s cellphone – for free.

Of course, you can already send free text messages with online services such as http://www.sendsmsnow.com/ but you can do it now in the comfort of your own email account.

Here’s how:

Your mobile has an unique email address created by your wireless carrier. All you have to do is ask your friends to send emails to this email address and it’ll be sent to your cellphone – free of charge. The only caveat is that you’re limited to 160 characters. However, you can reply to the SMS to have the entire email sent to you.

Here’s a list of all Canadian carriers and their email format so you can find your own:
