Test your SMS campaign

You can access the test send function for SMS in two places:

  • The SMS campaign editing screen

  • On the SMS campaigns screen, in the Test send column.

To perform a test send:

  1. Select Test send.

  2. In the Test send side panel, select SELECT TEST NUMBER to choose contacts from your Test list (hold Ctrl to select multiple addresses), or select NEW TEST NUMBER to add a new contact to the Test list.
    You cannot add suppressed mobile numbers to your Test list. If you see an Errors found message when trying to add a new number, this is likely to be the reason why.

  3. Select TEST SEND to confirm the send.

  4. When you're finished with testing and ready to send, select SAVE & CONTINUE.
    If you’re not ready to send, you can select SAVE then exit the SMS editor, and return to your campaign later.

Keep it short

If your SMS is longer than 160 standard GSM characters, it costs more to send. Don't get caught out by extra costs.

Send your SMS campaign

You’ve created and tested your SMS campaign, now it's time to send it out.

To send a broadcast SMS campaign:

  1. Open your campaign in the SMS editor and select SAVE & CONTINUE or go to the SMS campaigns screen and select the Send icon for the campaign you want.

  2. Under the heading Select the contacts to send this campaign to, use the tabs to select the lists, segments and marketing preferences you want to send the SMS to.
    You can see the total number of contacts for each, as well as the number of contacts with a mobile number that the SMS can be sent to.

  3. Under the heading Select send time and speed:

    • For Select send time, select Immediately or Scheduled.

      If you select Scheduled, use the date picker to set the time and date of your send, then expand the time zone drop-down menu and select the time zone you are sending the SMS to.

      This doesn’t affect the time zone set on your account. You can only select one time zone for SMS sends.

    • For Select send speed, you can use the default sending speed, meaning as soon as possible, or choose to spread the campaign send out over 1, 2, 3, 6, 12 or 24 hours.

    • For Undelivered SMS, select Expire after three days if you want the standard SMS expiry time of three days.
      If you want your SMS to expire earlier, select Expire on, and then choose a date and time. You can set a minimum time of one hour and a maximum of three days (72 hours).
      If a network can’t deliver an SMS at the first attempt, they make multiple further attempts to deliver up to the message expiry time. The custom expiry is useful if your SMS is time-sensitive, for example, a 24-hour sale or travel updates, so you don’t want the network to continue trying to re-send the SMS for the full three days.

  4. Select CONTINUE.

  5. On the Send page, you see the total amount of contacts you're sending to.

    • You also see:

      • the From name that appears for those who receive the campaign

      • whether or not your message includes Unicode characters

      • whether or not you have turned on link shortening

      • the contacts you have chosen to send to

      • the send time

      • the message expiry

      • the number of recipients

      • the estimated credits used for this send
        This is an estimate only and doesn't account for longer messages due to personalisation.

    The option you see here depends on whether you chose to send an immediate or scheduled campaign.
