WhatsApp Templates: How to Write Message Templates That Get Approved and Drive Results

WhatsApp templates — the foundation of business communication

WhatsApp message templates (HSM - Highly Structured Messages) are the base of business communication on WhatsApp Business API. Unlike regular messages, they have to be pre-approved by Meta and meet strict content, format, and use-policy rules.

A deep understanding of how WhatsApp templates work is critical for businesses that want to use the platform successfully.

WhatsApp message template types

Marketing templates

For marketing messages, deals, and sales promotions. The most restricted template — requires strict compliance with anti-spam rules and specific Meta policies.

Popular use cases:

• Special deals and sales

• Launching new products

• Marketing campaigns

• Customer loyalty

Utility templates

For informational messages about orders, shipments, and services. More flexible in terms of approval, but require a clear connection to a specific action by the customer.

Popular use cases:

• Order confirmations and updates

• Appointment reminders

• Shipping updates

• Bill and payment notifications

Authentication templates

For sending verification codes (OTP) and two-factor authentication messages. The most focused templates, with a clear limitation to authentication use only.

Approval rules and guidelines

Content rules

• Clear language: the message should be clear, correct, and free of spelling mistakes

• Appropriate length: not too long, not too short

• Parameter usage: up to 10 parameters per template

Writing effective marketing templates

Successful structure

A successful marketing template includes three elements:

Eye-catching opening: an engaging opening sentence with the customer's name or the business name.

Clear value: concrete description of what the customer will gain — specific discount, new product, or unique deal.

Clear call to action: one specific action the customer should take.

Successful template examples

Time-limited deal

"Hi {{1}}, exclusive promo for you! 📱 30% off the new 2026 iPhone collection. Valid only until [tomorrow, until midnight]. Click here to take advantage: [dynamic link]"

Launching a new product

"{{1}}, breakthrough ahead! 🚀 We're launching a new product that will change your life - [product description]. As a valued customer, you get first access 48 hours before the public launch. View: [link]"

Loyal-customer message

"Dear {{1}}, as part of the loyalty program we prepared something special for you - {{2}} off the next purchase + free shipping. Enjoy your shopping! Use code: {{3}}"

Writing effective utility templates

Transactional messages

Customers expect fast, accurate information. Templates should be:

• Immediate and timely: sent when relevant

• Precise and detailed: all needed information in one message

• Secure and reliable: compliant with privacy and data protection rules

Practical examples

Order confirmation

"{{1}}, your order is confirmed! ✅ Order number: {{2}} Total: {{3}}₪ ETA: {{4}} Track your order: [link]"

Appointment reminder

"Reminder: {{1}}, you have an appointment tomorrow at {{2}} with {{3}} at {{4}}. For directions: [location link]. To reschedule: reply 'reschedule'"

Technical aspects of template building

Using dynamic parameters

WhatsApp templates support up to 10 dynamic parameters, marked in the message as {{1}}, {{2}}, etc. Every parameter is replaced with relevant personal information at send time.
