Could we have an auxiliary method that does something like:
`_send: function si_integration(data) {
sendMms: function si_sendMms(email) {
    try {
      new MozActivity({
        name: 'new',
        data: data
      });
    } catch (e) {
      console.log('WebActivities unavailable? : ' + e);
    }
  }
}`

and then reuse this in `sendSms` and `sendMms` ?

Does it make sense to you?
