Introduction
In the world of bulk SMS marketing in Kenya, your results are only as good as your contact list. A well-structured, segmented, and regularly updated list can be the difference between messages that convert and campaigns that go unnoticed.
At SMSLeopard, we make it simple for Kenyan businesses to upload, organize, and manage contacts in ways that maximize personalization and impact. Whether you’re a small business or a large enterprise, managing your database effectively is key to scaling your campaigns and improving ROI.
Why Contact List Management Matters
Better personalization → Customers respond more to messages that feel relevant.
Improved deliverability → Clean lists reduce bounce rates and protect your sender reputation.
Higher ROI → Targeting the right audience with the right message boosts conversions.
Regulatory compliance → Respecting opt-outs and DND (Do Not Disturb) lists ensures you remain compliant with Kenya’s Data Protection Act.
Step 1: Preparing Your Contact List
Before uploading, make sure your list is:
Formatted correctly → Use CSV or Excel formats.
Standardized → Phone numbers should be in international format (+2547XXXXXXXX).
Cleaned → Remove duplicates, invalid numbers, and outdated contacts.
Enriched with data → Include columns like Name, Location, Language, Birthday, Gender, or Purchase History for smarter segmentation.
Pro Tip: The more structured data you have, the more personalized and effective your campaigns will be.
Step 2: Uploading Contacts on SMSLeopard
Log in to your SMSLeopard Dashboard.
Go to the Contacts tab and click Upload.
Select your file (Excel or CSV).
Map columns (e.g., column A → Name, column B → Phone Number, column C → Location).
Review preview data, then click Confirm Upload.
SMSLeopard automatically deduplicates numbers to keep your list clean.
Step 3: Organizing Contacts
Once uploaded, it’s time to structure your database for efficiency:
Create groups/lists: For example, “VIP Customers,” “Nairobi Clients,” or “Dormant Leads.”
Tag contacts: Add labels like “Education,” “Retail,” or “Healthcare.”
Dynamic updates: As new leads or customers come in, add them directly into the right list.
Step 4: Segmenting for Maximum Impact
Segmentation allows you to send the right message to the right audience. On SMSLeopard, you can segment by:
Region/Location → Nairobi vs Kisumu campaigns.
Language → Kiswahili, Kikuyu, Luo, Kalenjin, etc., for inclusive marketing.
Behavior → Active vs dormant customers, frequent vs one-time buyers.
Demographics → Gender, age groups, birthdays.
Example: A retailer could send “Back to School” campaigns specifically to parents while sending “Clearance Sales” messages to bargain hunters.
Step 5: Maintaining List Hygiene
Your contact list is a living database. To keep it effective:
Regularly remove invalid or unsubscribed numbers.
Respect STOP messages and DND requests.
Refresh data (update birthdays, location, or behavior).
Run periodic audits to keep only active, relevant contacts.
Step 6: Using Lists in Campaigns
When creating a campaign:
Choose your Sender ID.
Select your target list or segment.
Personalize the message using dynamic tags (e.g., “Hi [Name], your reward points are expiring soon!”).
Send instantly or schedule based on the audience’s best response times.
Step 7: Advanced Contact Management with SMSLeopard
Integrations: Connect with CRMs and ERPs for automatic list syncing.
Automations: Build workflows that add/remove contacts based on behavior.
Analytics: Track response rates by list segment to see which audiences engage best.
