We all know why Bulk SMS Marketing is so popular with businesses of all sizes. Simplicity of use, low cost, great open and response rates. However, there can be a number of reasons why it is not working as well as it should for your company.
We’ve put together a list of why SMS Marketing might not be working for you, if you are doing any of the following, maybe have a think about how your customers perceive these SMS and try to come up with better campaigns.

Over-Messaging and List Fatigue
- Overuse of SMS: We’ve had tons of instances where a company uses Bulk SMS for the first time, gets an amazing response and then starts sending too many messages. This will 100% lead to higher opt-out rates. “The companies overutilizing sms definitely see higher opt-out rates.”
- List Fatigue: Frequent, irrelevant messages can cause subscribers to ignore or unsubscribe. “When SMS is treated like a faster email blast, fatigue shows up fast.”
Poor Segmentation and Targeting
- Generic Blasts: Sending the same message to your entire list can be ineffective. “Generic blasts are dead now.”
- Lack of Personalization: Subscribers expect relevant and timely messages. “You need to sound like a human who knows the customer, not a bot yelling about a sale.”
Compliance and Legal Issues
- Opt-In Requirements: Everyone must explicitly opt-in before you can text them. “Everyone has to explicitly opt in before you text them.”
- Compliance Costs: Navigating the legal landscape can be challenging and costly. “The compliance costs for doing a SMS campaign will generally run more than $80.”
Technical Issues
- Inbox Filtering: Apple’s iOS 26 update has made SMS filtering more aggressive. “If your number isn’t saved in someone’s phone, your texts might go to an ‘Unknown Senders’ tab that nobody checks.”
- Spam Folder: SMS is now getting a spam folder, which can affect deliverability. “SMS is getting a spam folder.”
How to Improve SMS Marketing
OK so let’s talk about how to improve your Bulk SMS Marketing.
Optimize Message Frequency
- Reduce Frequency: Sending fewer, more targeted messages can improve engagement. “Typically sweet spot is 2 campaigns a month.”
- Cap SMS by Context: Limit the number of texts per specific customer action. “Max 2 texts per cart, 3 per trial, 1 per event reminder.”
Enhance Segmentation and Personalization
- Behavioral Targeting: Use customer behavior to trigger SMS messages. “Send messages based on what people actually looked at or bought.”
- Segment Your List: Treat SMS as a high-trust channel for your most engaged audience. “SMS works best for your most engaged audience, not your entire database.”
Compliance and Best Practices
- Ensure Opt-In: Make it easy for customers to opt-in and always include an opt-out option. “Add a ‘save our number’ step to your welcome flow.”
- Use Reputable Platforms: Platforms like Sendmode, Attentive, and Textedly can help manage compliance and optimize campaigns. “Most teams use an SMS provider that bakes in compliance, opt-in tracking, and registration support.”
Leverage Automation and Rich Media
- Automated Flows: Use SMS for high-intent, time-sensitive moments like cart abandonment and restock alerts. “SMS works GREAT for time-sensitive offers and high-intent moments.”
- Rich Media: Consider using RCS (Rich Communication Services) for branded layouts and interactive messages. “RCS is basically iMessage for brands.”
Additional Tips
- Test and Iterate: Continuously test different approaches and iterate based on performance. “Start small, test messages, and always make opt-out super easy.”
- Combine Channels: Use SMS in conjunction with email and other marketing channels for a balanced approach. “Use both. Email for nurture, SMS for urgency.”
