Business Messaging: Templates for Marketing, Utility & Authentication ((Best Practices Inside!)

Sending messages one by one, copy-pasting replies, and worrying about whether your customers see your updates?

That’s the old way. With WhatsApp Message Templates and iSlash AI, you can deliver messages at scale—and still make them feel personal.

Message Templates aren’t just about saving time. They’re about starting conversations that matter, staying compliant with Meta policies, and converting attention into action.

Here’s how to make the most of them 👇

What Are Message Templates?

Message templates are pre-approved messages you can send to customers who haven't messaged you in the last 24 hours. These templates must be submitted for approval by Meta before use.

They are your first hello, your next-step reminder, and your limited-time offer.

Think of them as conversation starters. The real goal? Get customers to reply.

That way, the session becomes a two-way conversation—which not only builds engagement but also lowers your cost. Once a user replies, you can send unlimited messages within the 24-hour session without additional charges.

Before we dive into the types of templates, it’s important to understand the two main types of conversations on WhatsApp:

1. Business-Initiated Conversations

These are messages you send first—outside the 24-hour window. They require approved templates, and are divided into 3 categories:

• Marketing

• Utility

• Authentication

Note: Business-initiated messages are charged based on the number of conversations and the template category you use.

2. Customer-Initiated Conversations

These happen when the customer messages you first. You can respond freely within a 24-hour window without needing a template.

They include:

• Service messages

Good news: As of 1 Nov 2024, customer-initiated (Service) conversations are free of charge.

Three Types of Message Templates

Now that you know the difference, let’s explore the three types of message templates you can use on WhatsApp API

These templates are categorized based on intent and use case:

1. Marketing

Use for promotional messages, offers, new launches, product recommendations, or re-engagement.

When to use:

• When you want to promote a sale or product

• When you need to bring back customers who haven’t interacted for a while

• When you want to boost campaign reach via WhatsApp

2. Utility

Used for transactional updates like order confirmations, shipping updates, or billing reminders.

When to use:

• Right after a customer places an order

• When there’s a change in their delivery status

• To send invoices, receipts, or subscription updates

3. Authentication

For sending one-time passcodes (OTP) during login, account verification, or transaction confirmations.

When to use:

• During customer login or password reset

• To verify sensitive actions or payments

From Copy-Paste to Click-Send: Why Templates Save Teams Time

Templates don’t just live longer—they work smarter.

Once approved, you can reuse them again and again. Think of them like WhatsApp Business’s Quick Replies—but way more powerful.

✅ Templates can be customized

✅ Templates can be interactive

✅ Templates can even feel human

Instead of writing the same update 100 times, just hit send—complete with dynamic content, buttons, and automation triggers.

Yes, They Can Be Personal: Variables & Dynamic Content

Templates don’t mean robotic messages.

With variables like {{1}}, {{2}}, and {{3}}, you create flexible message drafts. Dynamic content fills in those placeholders to personalize each message for the recipient.

Example:

• Variable: Hi {{1}}, your order {{2}} has been shipped.

• Actual Message: Hi Sarah, your order #888 has been shipped.

You can dynamically mention a customer’s name, product, time, order ID—even tailor upsells or follow-ups based on what they last bought.

Personalized messages aren’t just nice—they work. They feel relevant and respectful, making customers more likely to respond, click, or complete a purchase.

Add-On That Converts: Headers, Footers, Buttons 🚀

Want customers to take action instantly? With iSlash AI, you can make your message template rich, clear, and action-friendly:

• Header (Optional): Add context with text, image, document, or video.

• Body Message (Required): The main content of your message.

• Footer (Optional): Appears in italic grey text. (Commonly used for small notes like opt-in/opt-out instructions.)

Pro Tip: Use the footer to clearly let users know they can reply or unsubscribe. It improves transparency and compliance.

Make It Interactive: Add Reply Buttons

iSlash AI lets you reply buttons per message template. These increase customer engagement and streamline responses.

Here’s what you can add:

1. Quick Reply

• A simple, tappable response

• Trigger automation like chatbots or workflows

• Example: “Confirm Booking”, “Show More”, “Talk to Agent”

2. URL Button

• Link to a website, cart, payment page, etc.

• Customizable label and URL

3. Phone Number Button

• Lets customers call you directly

4. Flow Button

• Launch a WhatsApp-native form (Flow) to collect data easily

These buttons simplify the customer journey and boost conversion by reducing friction.

Approval Process & Template Status

Once you’ve designed your template, submit it for Meta review. This typically takes a few minutes to a few hours.

Template Statuses:

• Pending – Under review.

• Approved – Ready to use.

• Rejected – Needs fixing

Why Was My Template Rejected?

Avoid these common pitfalls:

❌Content amp; Policy Violations

1. Content doesn’t comply with WhatsApp’s Commerce Policy

2. Content violates WhatsApp’s Business Polic

3. You request sensitive info (like ID or banking details)

4. Language is threatening or abusive

❌Parameter Formatting Issues

1. Missing or mismatched variables—should be {{1}}, {{2}}, etc.

2. Non-sequential variables (don’t skip numbers)

3. The message ends with a variable—this is not allowed

✅ Fixes:

1. Rephrase or remove violating content

2. Replace sensitive data requests with secure alternatives

3. Ensure correct placeholder syntax and order

4. Add a closing sentence after your last variable

Template Status: Monitor Performance

Even after approval, template status can change based on customer engagement.

Templates with Active status can still be used—but watch performance closely. Improve copy or targeting if status drops.

Monitor status regularly and update poorly performing templates to avoid deactivation.
