Click-to-WhatsApp Ads Free Message Window Extended from 72 Hours to 7 Days: Rule Changes and Enterprise Response Guide

Author: SaleSmartly

On September 28, 2026, Meta officially updated the WhatsApp Business Platform pricing guidelines, adjusting the Free Entry Point (FEP) free message window policy for Click-to-WhatsApp Ads (CTWA). Previously, the FEP free message window initiated via CTWA ads lasted for 72 hours; following this latest policy update, the free message window has been officially extended to up to 7 days.

For businesses running ads via Meta and utilizing WhatsApp for overseas customer acquisition and lead conversion, this rule change translates to more ample customer follow-up time and lower conversation costs. This article details the specific updates of the latest CTWA policy, activation conditions, the differences between the two types of windows, billing rules, and how businesses can leverage third-party tools to efficiently manage and follow up on CTWA ad leads.

 

 

I. CTWA Free Message Window Policy Update: Extended from 72 Hours to Up to 7 Days

What Are CTWA and Free Entry Point (FEP)?

Click-to-WhatsApp Ads(CTWA)refer to ad formats that direct users straight into a WhatsApp chat. When potential customers click an ad with a "Send WhatsApp Message" button on Facebook or Instagram, the system automatically redirects them to the enterprise's WhatsApp Business account page and initiates a conversation, eliminating the tedious steps of visiting an independent website or adding contacts manually.

When users initiate a consultation through such ads, Meta assigns a Free Entry Point (FEP) window to eligible conversations. During this active window, message exchanges that comply with platform rules are exempt from Meta's official conversation fees.

What Is the Difference Between the 72-Hour and 7-Day Rules?

Prior to the implementation of the new policy, the FEP free window had a strict time cap of only 72 hours. Once 3 days passed, if businesses wanted to proactively follow up with hesitating customers, they had to use approved paid message templates and pay additional conversation fees.

Under the latest adjustment, the free window has been extended to a maximum of 7 days. The most direct impact of this change is that businesses gain an extended period of free communication. For cross-border B2B and independent e-commerce merchants with higher average order values, longer customer decision-making paths, or the need for multi-round repeated communication, the communication rhythm is no longer strictly confined to the original 72-hour window, which will also lower conversion costs.

 

 

II. How to Activate the 7-Day Free Window for CTWA?

Many merchants mistakenly believe that as long as a user clicks an ad, the 7-day free window will automatically open, but this is not the case. To successfully activate this window, businesses must first verify the ad entry point and account binding status: the ad must originate from official designated CTWA entry points on Facebook/Instagram, and the Meta ad account must be correctly linked to a verified WhatsApp Business API / Partner account.

The countdown for the free window begins the moment the enterprise completes its first compliant response, rather than when the customer clicks the ad or sends the initial message. Therefore, to ensure eligibility for the 7-day free qualification and enhance the conversion experience, it is recommended that businesses arrange manual or automated responses at the very first instance of receiving an inquiry.

When a potential customer sends the first message to a business via an ad, the enterprise must make its initial reply within 24 hours. If no response is made for over 24 hours, the 7-day FEP free window will be invalidated, and all subsequent communications will revert to standard billing.

III. What Is the Difference Between the 7-Day Free Window and the 24-Hour Customer Service Window?

Within the WhatsApp API operational framework, there are two independently operating "window" mechanisms that many managers easily confuse.

The core function of the CTWA 7-day free window is to control billing costs. It opens upon the enterprise's compliant initial response and lasts for 168 hours, during which Meta-side WhatsApp conversation fees are waived.

In contrast, the core function of the 24-hour customer service window is to control message type sending permissions. It is triggered the moment the user last sends a message to the enterprise and lasts for 24 hours (with each user reply resetting this 24-hour timer). Within 24 hours, enterprises can send any free-format text to customers; once the 24-hour mark passes without a new customer reply, the window closes, and enterprises must use pre-approved template messages to proactively contact customers again.

Feature / Aspect

CTWA 7-Day Free Window

24-Hour Customer Service Window

Trigger & Reset Mechanism

 

Opened when the enterprise first replies to a customer message within 24 hours; fixed duration of 168 hours. Subsequent customer messages do not reset this 7-day countdown.

Triggered when the customer last messages the enterprise; fixed duration of 24 hours, refreshed with every customer message.

Core Control Function

 

Controls billing costs: determines whether messages generated from specific entry points enjoy Meta fee waivers.

Controls message type permissions: determines whether enterprises can send free-format messages or must use template messages.

Message Sending Permissions

 

Eligible messages sent during the window period are exempt from Meta official conversation fees.

Any free-format text can be sent during the window period; expired without reply means only approved template messages can be sent.

These two windows are calculated independently and do not affect each other. If a customer stops responding for more than 24 hours within the 7-day FEP free period, the 24-hour customer service window will temporarily close. At this point, you need to send a template message to re-engage the customer; however, because the conversation is still within the 7-day FEP free period, the template message you send remains exempt from Meta official conversation fees.

 

 

IV. What Fees Are Waived by the CTWA 7-Day Free Window? What Are the Subsequent Billing Rules?

Within the active 7-day FEP window, eligible messages (including free-format messages and compliant template messages) are exempt from Meta WhatsApp conversation fees. Ad display and click costs on Facebook and Instagram still need to be paid normally.

Once the window expires or becomes invalid, billing rules will differ: if the FEP window has ended but the 24-hour customer service window is still active, non-template messages sent by enterprises will be charged service conversation fees according to Meta's latest standards; if both windows have closed, paid template messages must be used to re-establish contact, and corresponding template charges will apply.

It is worth noting for businesses that, following Meta's new billing rules implemented on October 1, 2026, service messages within the standard Service Window have also been included in the billable scope. Against this backdrop, the cost-effectiveness and cost advantages of the 7-day completely free message window (FEP) provided by CTWA ads become even more prominent, helping businesses save substantial private-domain communication expenses.

 

 

V. How Enterprises Can Leverage the 7-Day Window for CTWA Lead Follow-Up

The extension of the free window provides businesses with more ample customer communication time, but driving conversions still depends on whether the follow-up is timely and effective. Enterprises need to respond to customer inquiries promptly, provide product information, quotes, or solutions based on actual needs, and clearly outline the next communication steps. If a business cannot keep track of every lead's communication history, assigned owner, and current progress in real time, it will be difficult to fully utilize this extra time. Therefore, in addition to formulating reasonable follow-up strategies, businesses also need a workflow system capable of centralizing customer messages, clarifying conversation ownership, and continuously recording lead statuses.

VII. FAQ

1. Will CTWA conversations already opened before the policy took effect also be automatically extended to 7 days?

No. Meta's update applies only to eligible new CTWA conversations generated after the policy took effect (September 28, 2026). Older conversations opened prior to this will not be retroactively extended to 7 days. It is recommended to confirm specific billing details with your WhatsApp API service provider.

 

2. If a customer sends another message within the 7 days, does the free window reset its timer?

No. The FEP free entry window starts from the enterprise's compliant initial reply and has a fixed maximum duration of 7 days (168 hours); it will not reset the 7-day cycle due to multiple messages sent by the customer during that period. Further customer messages only refresh the 24-hour customer service window, and the two must be evaluated separately.

 

3. Are the CTWA 7-day free message window and the Meta Ads 7-day click attribution window the same thing?

No, they are not the same thing. The 7-day FEP free message window belongs to WhatsApp's messaging fee-waiver policy, whereas the 7-day click attribution window belongs to Meta Ads Manager's conversion data statistical model. Attribution settings in the ad backend do not change the activation conditions and billing rules of the FEP free message window.

 

 

Conclusion

The extension of the Click-to-WhatsApp Ads free message window from 72 hours to up to 7 days provides eligible businesses with more adequate customer communication time. When executing this strategy, businesses should focus on three core aspects: confirming eligibility for the free window, strictly distinguishing between FEP and the 24-hour customer service window, and accurately calculating message and related service fees based on the rules.

Building upon this, leveraging unified management tools like SaleSmartly to achieve efficient responses, conversation distribution, and status tagging can transform longer communication windows into more orderly and higher-converting customer service workflows.
