Check your campaign results. If you see all of your messages failed check the following: Ensure your list is not set to dial the country code for the number by clicking on the EDIT button next to your list, and looking for the box that indicates “I entered a 1 in front of my US or Canadian numbers”. If there is not a 1 in front of the area code on your list, this box should NOT be checked. Deselect the box, and relaunch your campaign.
Check the CAMPAIGN HISTORY section of the dashboard to ensure you launched the campaign. If you do NOT see the campaign in this area, it means you did not launch the campaign.
