1. Introduction
SMS marketing is a powerful tool, but it must be used responsibly and in compliance with local laws. This
guide helps you understand the regulations governing SMS communication across East Africa.
⚠️ Legal Responsibility: As a user of Bulk SMS Sender, YOU are responsible for ensuring
your SMS campaigns comply with all applicable laws and regulations. Non-compliance may result in:
- Fines from regulatory authorities
- Account suspension
- Legal action
- Damage to your brand reputation
2. General Principles (All Countries)
Regardless of which East African country you're operating in, follow these core principles:
✅ DO
- Get explicit consent before sending marketing SMS
- Provide easy opt-out mechanism in every message
- Honor opt-out requests immediately
- Use accurate Sender IDs
- Send during reasonable hours (8 AM - 8 PM)
- Keep records of consent
- Be transparent about who's messaging
❌ DON'T
- Send unsolicited spam messages
- Use misleading Sender IDs
- Send at night or early morning
- Continue after opt-out request
- Hide your identity
- Send to numbers from purchased lists (without consent)
- Use deceptive marketing tactics
3. Consent Requirements
3.1 What is Valid Consent?
Valid consent must be:
- Explicit: Clear agreement to receive SMS (checkbox, form submission, verbal
agreement)
- Informed: Recipients know what they're signing up for
- Documented: You have proof of when and how consent was obtained
- Current: Not obtained years ago for a different purpose
3.2 Examples of Valid Consent
✅ Valid Consent Scenarios:
- Customer fills out a form with "I agree to receive SMS updates" checkbox
- Customer provides phone number during purchase and agrees to marketing
- Visitor opts in via your website's SMS subscription form
- Customer verbally agrees during phone call (recorded or documented)
- Existing customers (with implied consent from business relationship)
3.3 Examples of Invalid Consent
❌ Invalid Consent Scenarios:
- Buying or scraping phone number lists
- Pre-checked consent boxes
- Obtaining numbers through contests without explicit SMS consent
- Using customer service numbers for marketing
- Assuming consent because someone visited your website
4. Opt-Out Requirements
4.1 Mandatory Opt-Out Mechanism
Every marketing SMS must include a clear way to opt out. Common methods:
- "Reply STOP to unsubscribe" (most common)
- "SMS STOP to 12345" (dedicated short code)
- "Text NO to opt out"
4.2 Example Messages
Good Example:
"Hi John! 🎉 Get 20% off all products this weekend at ShopTZ. Use code WEEKEND20. Valid until Sunday.
Reply STOP to opt out."
Bad Example:
"HUGE SALE! BUY NOW!!!" (No opt-out, no sender identification)
4.3 Processing Opt-Outs
When someone opts out:
- Remove them from your list immediately (within 24 hours)
- Send confirmation: "You've been unsubscribed. You won't receive further messages."
- Keep a record of the opt-out
- Never re-add them without explicit new consent
