Edit an SMS campaign
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.
To edit a previously saved SMS campaign:
Go to Campaigns > SMS.
Select the SMS campaign you want to edit.
Make any changes you want to your campaign.
Select SAVE & CONTINUE.
When you're happy with your campaign, you can select your contacts, test and send your campaign.
