A2P 10DLC systemIf you ever find out that your campaign text messages get blocked by Twilio or they've been marked as spam (due to suspicious links, etc.), most likely it's a problem with TinyURL supposing that you're using TinyURL as your SMS link shortener.
Possible fix:
• Try switching to another shortener for your SMS such as Bitly and Rebrandly. Afterward, test out your campaign again and see if you receive the text message.
Another reason for blockage is the A2P 10DLC system. If the campaign number has not been assigned to a verified A2P 10DLC campaign, you can expect that the campaign messages will be blocked. Here's a training link to the A2P 10DLC registration inside the Coupon Reach software training course.
