Here are a few tips to help you get the most out of your SMS campaign:
Break up your lead data into smaller chunks rather than sending a single message to a large number of people.
Keep each SMS message under 140 characters and make them more conversational rather than promotional.
Personalize your messages by using tags like {{First Name}} to add a personal touch.
Be aware that carriers may be stricter with their SMS policies, so it's a good idea to test smaller groups of messages first to ensure they are being delivered successfully. Sending a large number of messages at once may result in some of them being blocked or held in a queue.
