Avoiding Message Fatigue: Frequency Caps and Respecting DND in Kenya.

Introduction
SMS remains one of the most trusted, personal, and effective communication channels in Kenya. Whether it’s a SACCO reminding members of repayments, a church inviting congregants to fellowship, or an e-commerce store announcing a flash sale, SMS reaches audiences instantly.
But here’s the challenge: too many messages can backfire. Instead of building loyalty, it can cause message fatigue—where customers ignore, unsubscribe, or even complain about your brand.
With SMSLeopard, Kenya’s leading SMS platform, you can easily manage frequency caps and ensure compliance with Do Not Disturb (DND) regulations, helping you deliver impactful campaigns without overwhelming your audience.
What is Message Fatigue?
Message fatigue occurs when recipients feel overwhelmed or annoyed by too many SMS campaigns. Signs include:
Falling engagement rates (open or click-through).
Increased opt-outs/unsubscribes.
Customer complaints to regulators or your brand.
In Kenya’s mobile-first market, protecting trust is crucial for long-term success.
Why Frequency Caps Matter
A frequency cap is a rule that limits how many SMS a recipient can receive within a certain time.
Benefits include:
Avoiding irritation by spacing out messages.
Ensuring each campaign feels fresh and relevant.
Protecting your sender ID reputation.
Building sustainable customer relationships.
Example: Instead of sending 3 promo messages per day, cap it at 2 per week per customer.
Understanding DND Regulations in Kenya
Kenya’s Communication Authority (CA) and telecom operators (Safaricom, Airtel, Telkom) enforce Do Not Disturb (DND) lists.
Customers can opt out of promotional SMS by sending STOP or using carrier options.
Businesses must respect opt-outs immediately—sending to opted-out numbers can result in penalties and blocked sender IDs.
Transactional SMS (e.g., bank alerts, OTPs, healthcare reminders) are exempt from DND but must still be relevant and minimal.
Best Practices for Avoiding Message Fatigue
1. Set Frequency Caps
Use SMSLeopard to limit how many messages a customer receives daily, weekly, or monthly.
2. Segment Audiences
Send messages only to relevant groups. For example, notify Nairobi-based customers of an in-store sale, not the entire country.
3. Mix Content Types
Balance promotional SMS with useful ones—like tips, reminders, or appreciation messages.
4. Time Campaigns Strategically
Avoid sending multiple campaigns within the same day unless urgent.
5. Respect Opt-Outs Immediately
Always include an opt-out option (“Reply STOP to unsubscribe”) and honor it instantly.
6. Track Engagement
Monitor delivery, open, and response rates. If engagement drops, you may be sending too frequently.
Case Study Example
A Nairobi-based retail chain using SMSLeopard reduced its weekly campaign frequency from 5 to 2 per customer.
Before: 8% click-through rate, many unsubscribes.
After: 22% click-through rate, opt-outs dropped by 70%.
Lesson: Less is more when it comes to SMS marketing.
