Driving sales with SMS campaigns

SMS is the fastest way to reach your Kenyan customers. Almost every adult owns a phone, and SMS has open rates above 90%. Here are the campaign types that actually move stock.

Campaign Types That Work

Flash sales , 24 hours only. Create urgency. "Today only: 20% off all white shirts. Visit our shop on River Road." Keep the window short. Your customers know if they wait, they lose.

New stock alerts. When new products arrive, tell your regulars first. "New Samsung Galaxy cases just landed. Be the first to grab yours at Kimathi Street store." This works especially well for electronics, fashion, and phone accessories. Your regular customers appreciate being treated as insiders, and the exclusivity drives them to act faster.

Holiday promos. Tie your offer to the calendar. "Jamhuri Day special , buy 2 get 1 free on all moisturizers. Offer ends Sunday." Kenyan shoppers respond to holiday-linked deals because they are already in a buying mood. Other high-performing holiday windows include Easter, Madaraka Day, Mashujaa Day, Christmas, and the back-to-school season in January. Each of these moments gives you a natural reason to send a message without feeling spammy.

Loyalty rewards. Send a personal thank-you. "Thanks for being a regular customer, Jane. Show this SMS for a free soda with your next purchase." These messages cost you almost nothing but build enormous goodwill. A customer who receives a personal reward SMS feels valued and is far more likely to return.

Re-engagement campaigns. What about customers who have not visited in three months? Send them a "We miss you" message with a small incentive. "It has been a while. Come back this week and get 10% off your next purchase." Reactivating an old customer costs far less than acquiring a new one.

Writing CTAs That Convert

Every SMS needs one clear next step. Do not bury the ask.

• Bad: "We have new items in store, visit us when you can."
• Good: "Reply YES to reserve yours. Pick up at our Muthurwa outlet today."

Use action verbs: Visit, Reply, Show, Call, Order. Tell the customer exactly what to do and give them a reason to do it now.

A common mistake Kenyan businesses make is trying to include too much information in a single SMS. Remember the 160-character limit. If your message is longer, it splits into multiple texts and looks fragmented on the customer's phone. Stick to one offer, one CTA, one deadline.

Here is a formula that consistently works:

Greeting + Offer + Deadline + Action

Example: "Hi Jane! 20% off all shoes this Saturday only. Visit our Moi Avenue store and show this message. See you!"

Notice how every word serves a purpose. There is no fluff, no background story, no multiple offers. Just a clear, compelling message that drives action.

Timing Matters

When you send your SMS is just as important as what you say. Kenyan consumers check their phones frequently, but there are peak times when they are most receptive to shopping messages:

• Thursday evening (5-7 PM): People are planning their weekend shopping. A Thursday message about a weekend sale performs exceptionally well.
• Friday morning (8-10 AM): Payday for many salaried workers. This is the ideal time for flash sale announcements.
• Saturday morning (9-11 AM): Active shopping time. Many people are already out and about and can easily detour to your shop.
• End of month (25th-30th): Salary season. Campaigns during this window see the highest conversion rates across all categories.

Avoid sending messages late at night (after 8 PM) or very early in the morning. Not only is it intrusive, but it can also lead to customers blocking your number.

Building Your SMS List

A campaign is only as good as your contact list. Start collecting customer phone numbers from day one. Every time a customer makes a purchase, ask for their number. You can offer a small incentive , "Give us your number and get KES 50 off your next purchase" , to grow your list quickly.

In SokoWise, every customer who transacts with you is automatically added to your customer database with their phone number. This means your SMS list grows naturally as you do business. No extra work, no manual data entry.

Segment your list by purchase behaviour. Customers who buy electronics respond differently to offers than customers who buy groceries. SokoWise lets you create customer segments based on purchase history, so you can send the right offer to the right people. Sending a flash sale on phone cases to someone who only buys maize flour is wasted effort , and it annoys the customer.

Tracking ROI with SokoWise Delivery Reports

You cannot improve what you do not measure. SokoWise gives you a delivery report for every campaign:

• Delivered , how many phones received your message.
• Failed , numbers that bounced.
• Click or response rate (if you use a reply number).

Compare last month's payday campaign to this month's. Which day got more responses? Which offer got more shop visits? The dashboard stores your campaign history so you can check anytime.

To calculate ROI, use this simple formula: (Revenue generated from campaign - Cost of SMS sent) / Cost of SMS sent x 100.

For example, if you spent KES 500 on 1,000 SMS messages and generated KES 8,000 in sales from customers who mentioned the SMS: ROI = (8,000 - 500) / 500 x 100 = 1,500%. That is a 15x return on your investment. Very few marketing channels can match that kind of performance.

Common SMS Mistakes to Avoid

Even well-intentioned SMS campaigns can fail. Here are mistakes to watch out for:

Sending too frequently. One message per week is the maximum. More than that and customers will feel harassed. They might block your number or complain to the Communications Authority of Kenya.

No clear offer. "Visit our store for great deals" is too vague. The customer has no reason to move. Always include a specific discount, freebie, or limited-time promotion.

Wrong audience. Sending a back-to-school promotion to customers without children is a waste. Segment your list and target relevant offers.

No tracking. If you do not ask customers how they heard about you, you cannot measure SMS effectiveness. Train your staff to ask "How did you hear about this promotion?" and log the answer.
