To understand the reach of the channel, just look at WhatsApp's global adoption as a messaging platform. A general overview is available at Wikipedia:

Typically the steps include:
- Business Manager Verification,
- number and profile configuration,
- choice of platform or provider,
- integrations and templates.

Best practices for results and compliance
APIs work best when the message and process are designed together.
Writing messages
Use short sentences. Avoid ambiguity. Always include a unique CTA.
Also, personalize with real data. However, don't overdo it with sensitive details.
Conversation Management
Create assignment rules. Define macro-categories. Add tags for contact reasons.
Therefore, you reduce average management time. You also increase the quality of your reports.
Intelligent automations
Automate:
- initial data collection,
- answers to frequently asked questions,
- status notifications.
Then, it passes to an operator when the request is complex.
KPIs to monitor (with practical examples)
Without measurement, you don't improve. With WhatsApp, KPIs need to be simple.
- Time to First Response: how long does it take to respond.
- Resolution Time: how long does it take to close the case.
- CSAT: customer satisfaction after assistance.
- Conversion Rate: sales or bookings generated.
- Opt-in rate: growth of consenting contacts.
- Performance template: rendering of structured messages.
To understand the economic value of digitalization and direct channels, you can consult analyses and indicators in institutional reports. A point of reference is the OECD on measuring the digital economy:

Common mistakes to avoid
Many projects fail for trivial reasons. Here are the most common mistakes.
- Use WhatsApp as a “newsletter”.
- Sending too many messages in a short time.
- Not managing consent and preferences correctly.
- Do not expect escalation to operator.
- Do not integrate CRM and customer history.
- Measure only “messages sent”.
Additionally, avoiding confusing templates reduces waste and complaints.
