Your last newsletter had an open rate of 22% – and you were satisfied. That's standard for the industry. WhatsApp messages, on the other hand, are opened over 90% of the time, usually within 3 minutes. That's not a small difference; that's a different ballgame.
For many Swiss SMEs, WhatsApp Business is still a blind spot. Yet, the app is free, already installed on every smartphone, and perceived as trustworthy by your customers.
WhatsApp Business vs. WhatsApp Business API: What You Need
There are two versions:
WhatsApp Business App (Free): For solo entrepreneurs and small businesses with up to 2-3 people managing WhatsApp. You can create catalogs, save quick replies, set up away messages, and communicate with up to 256 contacts simultaneously (broadcast lists). Important: Recipients must have you saved as a contact.
WhatsApp Business Platform (API): For companies looking to scale. It enables automated messages, CRM integration, and unlimited recipients. Costs are incurred per message sent (approx. 0.05–0.15 CHF/message, depending on the category). Access is via providers like Twilio, Bird, or 360dialog.
For most SMEs in Switzerland: Start with the free Business App.
Legal Foundations in Switzerland
WhatsApp marketing is subject to the Swiss Federal Act on Data Protection (revised FADP, effective September 2023). The key rules are:
- Opt-in is Mandatory: You may only contact individuals who have explicitly given you permission to message them via WhatsApp. A general "contact details provided" is not sufficient.
- Opt-out Must Always Be Possible: In every message, state how recipients can unsubscribe. A simple "Type STOP to unsubscribe" is enough.
- No Forwarding to Third Parties: Contact details may not be used for other purposes.
Practical Opt-in: Add a line on your website, receipts, and during personal customer interactions: "Subscribe to WhatsApp Updates: [Link to registration form or QR code]"
5 Concrete Use Cases for SMEs
1. Appointment Confirmations and Reminders: Send a reminder via WhatsApp 24 hours before an appointment. No-show rates for hair salons in Zurich that have implemented this: reduced by 30–40%.
2. Order Status Updates: "Your order #1247 is ready for pickup. Available from Thursday." Customers appreciate direct, personal information.
3. Exclusive Offers for Loyal Customers: "Only for our WhatsApp Community: This week, 15% off all winter jackets." These messages create urgency without feeling pushy.
4. After-Sales and Feedback: 2 days after a purchase: "How is the new device working out? If you have any questions, we are here." Leads to higher customer loyalty and spontaneous recommendations.
5. Customer Support: Responses on WhatsApp are perceived as more personal than email tickets. Especially ideal for industries with products that require explanation.
Using Broadcast Lists Effectively
Broadcast lists are the core of WhatsApp marketing with the Business App. Here’s how to proceed:
- Segment your contacts: Loyal customers, new customers, prospects, region.
- Create a broadcast list for each segment (max. 256 contacts).
- Send a maximum of 1–2 messages per week. More leads to unsubscribes.
- Mix formats: Text, images, short videos, PDFs. Vary them so messages don’t seem like spam.
Personalization helps enormously: Instead of "Hello" → "Hello [First Name]" (enter manually or automate with the API).
Measurement and Optimization
The Business App shows you delivery rates and read receipts. Track:
- Percentage of read messages (double blue checkmark)
- Response rate: How many reply?
- Conversion: How many people from your WhatsApp list purchase in the following week?
A direct response rate of 5–15% is good for broadcast messages. Individual conversations naturally have higher response rates.
