Worth Offers: This is widely seen when most of the offers are expired or cannot be redeemed. Therefore when you send something, make sure you update and pick offers which are pleasant to your customers to avoid unforeseen issues. Your offers need to be worthwhile and easy to redeem.
Target Audience: Stop sending SMS to everyone as it might be irrelevant for some of them. You should only send SMS to the target audience and their needs; this will make them feel special as you are offering what precisely they are looking out for. Sending daily and irrelevant SMS might interrupt and irritate the users which can lead them to unsubscribe you from their list.
Inappropriate Language: Avoid using complex jargon in your SMS content, which can be difficult for readers to understand. Use simple and clear language with relevant information. Slangs words such as ASAP, LOL, etc should be ideally avoided. SMS content speaks a lot about the sender or the company, so using professional language will build the brands credibility.
Poor Call-To-Action: Most of the SMS Marketing campaigns generally fail to capitalize due to its poor Call-To-Action or no concise Call-To-Action in the body of every message. Call to action for a response in every SMS should be sent. e.g., website link or a number to call and confirm the involvement should be mentioned towards the end of the message.
