We now support sending SMSes directly from your mail client.

To send an email, simply place an email address of the form {number}@sms.messagingengine.com in the To: line of your email.

Note that you must have an SMS sending number set up in your default personality. To do this, login to FastMail.FM, click Options, then Personalities, and ensure that the 'Mobile Number' is filled in correctly.

You also need to have pre-purchased SMS credits. Click Options, then 'Purchase SMS Credits' to buy these.
