In the USA and Canada you can send free SMS by using the email2SMS feature. This means you’ll need to create eMobile addresses for the recipient’s mobile number.

Replies from the recipient will be sent to your email address. Please specify your email address in the Email address text field of the Reply to Email preference pane.

If you’d like to receive replies at your mobile instead, enter in the Email address field the eMobile address of your own mobile number instead (see below).

You can use the eMobile plug-in to create an eMobile address for your mobile. The Quick Start eMobile section explains how.
