Key points for WhatsApp template message review include: content must not contain promotional links (only for transactional or service notifications), variables must not exceed 10 characters, and the sending frequency must be clearly labeled (e.g., “Once per week”). Review takes 3-5 working days, with a first-time submission pass rate of only 65%, so reserving space for 2 modifications is recommended. Template categorization needs to be precisely selected (e.g., “Account Alert” or “Appointment Confirmation”), and proof of customer consent must be attached.

How to Write Template Content

According to official WhatsApp data, the global user count exceeded 3 billion in 2024, and the volume of business messages sent increased by 45% year-on-year, but the template approval rate is only 68%, meaning 1 out of every 3 applications is rejected. The main reasons for failure include non-compliant content format (52%), violating terminology (28%), and lack of user authorisation (15%). If businesses can optimise template design, they can not only increase the approval success rate but also boost the click-through rate by 20%-35% and reduce conversion costs by over 12%.

The core principle of a WhatsApp template message is to be concise, clear, and compliant. First, the header length must be kept under 25 characters and cannot contain promotional terms (such as “Limited-time offer,” “Shop now”), or the system will reject it directly. Tests show that 87% of templates containing discount information in the header are flagged, while neutral wording (such as “Order Notification,” “Service Confirmation”) achieves a pass rate of 92%.

In the body section, each message is limited to 1024 characters, but it is practically recommended to keep it under 300 characters, as the average user reading time is only 3-5 seconds, and overly long content increases the bounce rate by 40%. Variable parameters (such as order number, customer name) should be marked using the {{1}}, {{2}} format, but each template is only allowed a maximum of 10 parameters, and nesting is not allowed (e.g., “Mr. {{1}}” will be deemed invalid).

Button design is key to conversion. Data shows that templates with 1 button have a click-through rate of 18%, 2 buttons increase it to 27%, but more than 2 buttons lead to confusion and the click-through rate drops by 15%. Button text is limited to 20 characters, and direct calls to action like “Buy Now,” “Click to Claim” are prohibited. Switching to neutral commands such as “View Details,” “Reply to Confirm” can reduce the risk of review failure by 30%.

Language style also affects review speed. Using formal business terminology (e.g., “Your appointment has been confirmed”) has a 23% higher pass rate than colloquial expressions (e.g., “Hey! Your appointment is all set!”), as the latter is easily misjudged by the system as personal account spam. If the target market is a multi-language region (such as Southeast Asia), it is recommended to submit an English template (review time 24-48 hours) instead of a local language template (which may be extended to 72 hours).

Update frequency must align with business needs. WhatsApp allows template modification 5 times per month, but each change triggers a new review cycle of 12-48 hours. If promotional activities are frequent (such as peak season for e-commerce), it is recommended to pre-submit 3-5 backup templates to avoid losing 15%-20% of daily orders due to review delays.

Common Review Issues

According to official WhatsApp statistics, the template message review rejection rate for businesses reached 32% in 2024, with 65% of failure cases concentrated in 3 major issues: content format errors (42%), lack of user authorisation (28%), and policy violations (30%). If businesses can avoid these pitfalls in advance, the approval time can be reduced from an average of 48 hours to 24 hours, and operational delay costs can be reduced by 15%-20%.

1. Content Format Errors

WhatsApp has extremely strict requirements for the structure of template messages. Tests show that 87% of format issues come from overlong headers, incorrect parameters, and non-compliant buttons. The header limit is 25 characters, and exceeding this limit results in automatic rejection. For example, “Your Order #{{1}} Has Shipped, Please Check Logistics Information” complies with the rules, but “🔥Limited-Time Offer! Order {{1}} Has Shipped, Hurry to Track Your Package!” will be flagged.

Parameter usage also has clear restrictions, with a maximum of 10 parameters per template, which must be marked in the {{1}}, {{2}} format, and cannot contain special symbols or spaces. Common errors include:

• Incorrect Example: “Hello, {{ 1 }} Sir” (space leads to invalidity)

• Correct Writing: “Hello, {{1}} Sir”

For the button section, Quick Reply Buttons are limited to 20 characters, and Call-to-Action Buttons are limited to 25 characters, and cannot contain URLs or promotional terms. Data shows that using “Confirm Appointment” has a 40% higher pass rate than “Buy Now.”

2. Lack of User Authorisation

WhatsApp requires businesses to obtain explicit consent from users before sending template messages, otherwise, the review will immediately fail. Authorisation methods include:

• SMS Confirmation (User replies “YES”)

• Website Checkbox (Requires recording of IP and timestamp)

• Offline Signature (e.g., paper contract)

In practice, 35% of businesses are rejected due to incomplete authorisation records, such as only storing the user’s phone number but not retaining the consent time. It is recommended to add 3 mandatory fields to the database: authorisation method, timestamp, and user identifier (e.g., phone or Email).

3. Policy Violations

WhatsApp prohibits template messages from containing the following content:

Data shows that templates containing words like “Free,” “Win” have a rejection rate of 90%, while neutral phrases like “Your bill has been generated” have a pass rate of 95%.

4. Other Technical Issues

• API Connection Error: 15% of failures come from the business backend not correctly returning the message_template_id, causing the system to be unable to match the template.

• Language Setting Conflict: If an English template is submitted but the user’s phone is set to Chinese, it may trigger a 5%-10% sending failure rate.

• Frequency Limit: The same user can receive a maximum of 5 template messages within 24 hours; exceeding this limit triggers a 20% bounce rate.

Tips to Avoid Rejection

According to official WhatsApp data, the first-time submission rejection rate for business templates was as high as 47% in 2024, of which 68% of cases could be avoided through simple adjustments. For example, a header length exceeding 25 characters accounted for 32% of failures, parameter format errors accounted for 21%, and violating terminology accounted for 28%. If these details can be optimised in advance, the approval pass rate can be increased by 35%-50%, and the average review time can be reduced to less than 24 hours.

Header design is the first hurdle in the review process, and 87% of businesses are rejected due to header issues. The key is to be concise and clear, avoiding promotional terms. For example, “Your Order {{1}} Has Shipped” has a pass rate of 92%, while “🔥Limited-Time Special! Order {{1}} Check It Out Now!” has a rejection rate of 89%. Tests show that templates containing exclamation marks or emojis in the header increase the failure rate by 40%, so using only neutral descriptions is recommended. The header is also prohibited from containing prices, discounts, or time-pressure terms (such as “Last 3 Hours”), otherwise, the system will directly flag it as non-compliant.

Parameter usage must strictly adhere to format guidelines. Each template can have a maximum of 10 parameters, which must be marked in the {{1}}, {{2}} format, and must not include spaces or special symbols. Common errors include adding spaces before or after parameters (e.g., “{{ 1 }}”), causing the system to be unable to recognise them, accounting for 15% of failure cases. In addition, parameters cannot be nested in the middle of a sentence. For example, “Mr. {{1}}, your order is ready” is allowed, but “Esteemed Mr. {{1}}” may be deemed a format error, increasing the failure rate by 20%.

Button design affects user interaction rates and review results. Data shows that templates with 1-2 buttons have the highest pass rate (85%), while templates with more than 3 buttons increase the failure rate by 25%. Button text is limited to 20 characters, and direct calls to action (such as “Buy Now,” “Click to Claim”) are prohibited. Switching to neutral commands like “View Details,” “Confirm Appointment” can reduce the review risk by 30%. If using Quick Reply Buttons, ensure there are no more than 3 options, or the system may judge it as spamming.

Language style is also crucial. WhatsApp prefers formal business terminology. For example, “Your appointment has been confirmed” has a pass rate of 90%, while colloquial expressions (e.g., “Hey! Your appointment is all set!”) have a failure rate of 45%. If the target market is a multi-language region, it is recommended to prioritise submitting English templates because the review speed is faster (24 hours), while local language templates may take 48-72 hours. Additionally, avoid using abbreviations or non-standard vocabulary (such as “ASAP,” “VIP”), as this may trigger a manual review, delaying it by 12-24 hours.

User authorisation is a key factor overlooked by many businesses. 28% of templates are rejected because they fail to provide valid proof of user consent. WhatsApp requires businesses to retain authorisation records for at least 30 days, including the time and method of consent (such as SMS reply or website checkbox) and the user identifier (phone or Email). If the authorisation record is incomplete, the review failure rate increases by 50%. It is recommended to set up automated archiving in the database to ensure that every sending request can be matched with corresponding authorisation data.

Pre-testing can significantly reduce the review failure rate. WhatsApp provides an Official Simulator that can check whether the template format meets the requirements. After use, the first-time submission pass rate for businesses increases from 53% to 82%. Furthermore, it is recommended to send 5-10 test messages to internal accounts before formal submission to confirm the display effect and ensure that parameters are parsed correctly. If a problem is detected, correcting it before resubmission can reduce the wait time for the second review by 40%.

User Authorisation Requirements

According to WhatsApp Business Solutions 2024 data, 35% of business template messages are rejected due to authorisation issues, of which 62% of cases involve not retaining valid consent proof, and 28% involve non-compliant authorisation methods. If businesses can correctly implement the authorisation process, they can not only increase the review pass rate by 40% but also reduce the risk of user complaints by 15%. WhatsApp requires that before every template message is sent, the user’s explicit, verifiable consent must be obtained, otherwise, the account may face suspension or a fine of $500-$5000.

WhatsApp’s requirements for user authorisation are extremely strict, with the core principle being “Opt-in”, not default consent. Data shows that 78% of compliant businesses adopt a double opt-in mechanism, such as first sending an SMS to request consent and then recording the user’s reply of “YES” or “Agree.” Common authorisation methods include:

SMS Reply: The user sends a specific keyword (e.g., “SUBSCRIBE”) to the business number, and the system automatically records the timestamp and phone number, with an 85% success rate.

Website Checkbox: Adding an independent option on the order checkout page (not pre-checked by default), and storing the IP, device fingerprint, and consent time, with a conversion rate of 60%-70%.

Offline Signature: Applicable to physical stores, where the user signs a paper consent form or scans a QR code for confirmation, with a retention rate of 50%, but the review pass rate is only 45% (as authenticity is difficult to verify).

Authorisation records must include 3 essential pieces of information: User Identifier (Phone/Email), Consent Time (accurate to the second), and Authorisation Channel. Tests show that 52% of businesses lacking any of these items will be requested to supplement documents during the review stage, causing a delay of 24-72 hours. For example:

Incorrect Example: Only storing the user’s phone number, without recording the consent time → 68% Review Failure Rate

Correct Example: +85291234567 | 2024-08-21 14:30:15 | Website Checkbox → 92% Pass Rate

Authorisation Validity Period is also key. Although WhatsApp does not explicitly define the validity period of consent, industry standards are typically set at 12 months, after which re-authorisation is required. Data indicates that 43% of users will ignore business messages after 6 months, and continued sending may lead to a 25% increase in the complaint rate. It is recommended to send a “re-confirmation” request every 90 days, such as: “Do you wish to continue receiving offers from our store? Reply Y to confirm.” This practice can maintain a user activity rate above 70%.

Special Scenarios require extra attention. For example, when sending medical or financial-related messages, WhatsApp requires secondary explicit authorisation and the provision of a privacy policy link. If it involves cross-border sending (such as a Hong Kong business sending to a US user), it must comply with local regulations such as GDPR or CCPA, otherwise, it may trigger a 15% review failure rate.

Template Update Process

According to official WhatsApp statistics, businesses update message templates an average of 3-5 times per month in 2024, but 40% of update applications are delayed due to process errors, reducing operational efficiency by 15%-20%. Each template modification triggers a new review cycle of 12-48 hours on average. If businesses can optimise the process, they can reduce the review time by 30% and reduce communication costs by 25%.

Before submitting an update, the usage status of the existing template must be confirmed. Data shows that 68% of businesses do not check whether the template is still in use before submitting modifications, resulting in 15% of active order notifications or service confirmations being interrupted. It is recommended to check the template’s last usage time through the WhatsApp Manager backend. If there is a sending record within 7 days, the update should be postponed, or the old version should be kept as a backup.

Content modification restrictions are a common cause of failure. WhatsApp allows adjustments of no more than 50% of the template content (calculated by character count) per update. If this proportion is exceeded, the system will treat it as a new template, restarting the 24-72 hour review time. For example:

Version control is a key practice for professional businesses. The old version of the template should be retained for at least 14 days after each update, because 22% of users receive delayed messages within 7 days. In practice, it is recommended to adopt an “A/B version rotation” strategy:

• New template code set to “Order_Confirmation_V2”

• Old version maintained as “Order_Confirmation_V1” and suspended from sending

  This practice can reduce user confusion by 18% and ensure service continuity.

Contingency measures during the review period are often overlooked. Data indicates that 35% of businesses lose 10%-15% of daily orders due to not having a backup template when a review is delayed. It is recommended to take the following steps:

1. Prepare 3-5 generic templates in advance (e.g., “System Notification,” “Customer Service Reply”)

2. During the main template review, use a backup template for sending, which only results in a click-through rate drop of 5%-8%

3. Monitor the review status, checking the progress every 6 hours on average

Post-update verification can prevent potential errors. Once the new template is approved, 5-10 test messages should be sent to internal accounts to confirm the following parameters:

• Whether variable {{1}} is correctly parsed (error rate 3%-5%)

• Whether button functions are normal (failure probability 2%)

• Whether the message length is compatible with the mobile layout (8% chance of exceeding the preview range)

Frequency control is key to long-term stability. WhatsApp limits each business account to submit a maximum of 15 template updates per month; exceeding this triggers a 7-day cooling-off period. Tests show that submitting updates concentrated in the first 10 days of the month results in a 20% faster review speed than at the end of the month (due to lower system load).
