# WhatsApp Business API Best Practices to Protect Your Number and Maintain High Quality

Using WhatsApp Business API responsibly is critical for maintaining number health, avoiding restrictions, and ensuring long-term growth.

This guide outlines essential best practices to help you stay compliant, protect your messaging quality, and maximize engagement.

***

#### <mark style="color:$primary;">**1. Always Message Users Who Have Given Consent**</mark>

Sending messages without permission increases the risk of blocks, complaints, and account restrictions.

Always collect opt-in consent before messaging users. Acceptable opt-in methods include:

* Website forms
* QR code scans
* Checkout consent checkboxes
* “Reply YES to subscribe” flows

#### Good Example

“Hi Riya, thanks for signing up. We’ll send you order updates and special offers on WhatsApp. Reply STOP anytime to unsubscribe.”

#### Incorrect Practice

Sending promotional messages to purchased or scraped contact lists.

#### Why This Protects Your Number

When users expect your messages, complaint rates stay low. Low complaint rates help maintain a high quality rating in Meta.

***

#### <mark style="color:$primary;">**2. Follow the 24-Hour Customer Care Window**</mark>

When a customer sends you a message, you have a 24-hour window to respond freely.

After 24 hours, you must use an approved message template.

#### Example

If a customer asks, “Where is my order?”, you may respond freely within 24 hours.

If you want to send a discount message after 48 hours, you must use an approved Marketing template.

#### Why This Protects Your Number

Using templates outside the 24-hour window ensures compliance with Meta’s messaging policies and prevents penalties.

***

#### <mark style="color:$primary;">**3. Use the Correct Template Category**</mark>

Every template must be categorized correctly:

* Utility: Service-related updates (order confirmation, appointment reminders)
* Marketing: Promotions, offers, product announcements
* Authentication: One-time passwords (OTPs)

#### Correct Example

“Hi Aditi, your appointment is confirmed for 4 PM.” (Utility)

#### Incorrect Example

“Hi Aditi, your appointment is confirmed. Also, here’s 20% off hair spa.”\
This should be a Marketing template, not Utility.

#### Why This Protects Your Number

Incorrect template categorization can lead to rejections, quality drops, and compliance flags.

***

#### <mark style="color:$primary;">**4. Avoid Cold Broadcasting**</mark>

Cold broadcasting to random or unengaged contacts significantly increases block rates.

Instead:

* Use Custom Audiences (past buyers, recent leads)
* Retarget users who interacted with ads
* Focus on users who have shown interest

#### Good Practice

“Thank you for shopping with us last month. Here’s early access to our festive sale.”

#### Poor Practice

Sending promotional messages to large, unverified contact lists.

#### Why This Protects Your Number

Warm audiences generate higher engagement and fewer complaints, helping maintain number quality.

***

#### <mark style="color:$primary;">**5. Send Valuable and Relevant Messages**</mark>

Messages should be:

* Clear
* Relevant
* Personalized when possible
* Focused on value

Include media, call-to-action buttons, or relevant links when appropriate.

#### Good Example

“Hi Aarav, your AC service is booked for 12 September. Technician: Raju (Contact: 9XXXXXX). Please confirm below.”

#### Poor Example

“AC SERVICE DISCOUNT. CALL NOW.”

#### Why This Protects Your Number

Useful messages increase engagement and reduce the likelihood of blocks.

***

#### <mark style="color:$primary;">**6. Maintain Healthy Message Frequency**</mark>

Avoid sending too many promotional messages in a short period.

Best practices:

* Limit to 1–2 outbound messages per day
* Allow 24–72 hours between follow-ups
* Gradually scale campaigns instead of blasting large volumes

#### Smart Campaign Flow

Day 1: Order update\
Day 3: Feedback request\
Day 7: Personalized offer

#### Risky Campaign Flow

Multiple promotional messages in a single day.

#### Why This Protects Your Number

High-frequency messaging increases block rates and may lead to quality degradation or restrictions.

***

#### <mark style="color:$primary;">**7. Always Provide an Opt-Out Option**</mark>

Users must be able to unsubscribe easily.

Include a simple opt-out instruction in your messages.

#### Good Example

“Reply STOP to unsubscribe from WhatsApp updates.”

If a user opts out, immediately stop messaging them.

#### Why This Protects Your Number

Ignoring opt-out requests can significantly impact your account quality and may result in restrictions.

***

#### <mark style="color:$primary;">**8. Monitor Your Number Health Regularly**</mark>

You can check your WhatsApp number health inside Meta Business Manager.

#### How to Check Number Health

1. Log in to Meta Business Manager.
2. Go to Business Settings.
3. Navigate to Accounts → WhatsApp Accounts.
4. Select your WhatsApp Business Account.
5. Open Phone Numbers.
6. Select the number you want to review.

You will see:

* Messaging Tier (1K, 10K, 100K, Unlimited)
* Quality Rating (High, Medium, Low)
* Status (Connected, Flagged, Restricted)

#### Understanding Quality Rating

High (Green): Messages are well received.\
Medium (Yellow): Some negative feedback detected.\
Low (Red): High block or complaint rate. Immediate corrective action required.

#### What Is Block Rate?

Block rate refers to how many users block your number after receiving your messages.

A high block rate lowers your quality rating and may lead to restrictions.

***

#### <mark style="color:$primary;">**9. What to Do If Quality Drops**</mark>

If your number quality drops or restrictions occur:

1. Pause outbound campaigns immediately.
2. Review your recent campaigns (audience, template, frequency).
3. Remove cold or unengaged leads.
4. Refine message content and template categorization.
5. Resume with service-first communication.
6. Contact DoubleTick Support with opt-in proof if required.

Taking proactive corrective action can help recover quality faster.

#### <mark style="color:$primary;">**10. Recommended Safe Messaging Flows**</mark>

E-commerce\
Order confirmation → Shipping update → Delivery feedback → Loyalty offer

Hospitality\
Booking confirmation → Reminder → Add-on suggestion → Feedback request

EdTech\
Enrollment confirmation → Class reminders → Progress updates → New batch promotion

Service-first communication followed by promotional messaging is safer and more effective.
