Quick answer
How do I run Black Friday on WhatsApp as a D2C brand in India? Message people who asked to hear from you. Split the week into three windows: a heads up, sale day, and a last call. Answer every reply the same day. Meta charges per delivered message for marketing, and a sale offer is a marketing message. Meta says service messages inside a customer’s 24 hour window are free.

Scope note: Message rules come from Meta’s WhatsApp Business pricing page, read 8 Nov 2026. Rupee rates differ by market and category and are on Meta’s rate card. I have not checked the India rupee figures for this article, so check them there before you budget. Dates were checked against the calendar. Not legal advice.
Most brands plan the blast and forget the replies.
The sale happens in the reply, so plan the replies before you send.
Here is the plan, the rules behind it, and three scripts you can copy today.
Is WhatsApp worth it for Black Friday?
Yes, when the people on your list asked to hear from you and you can answer them on the day. No, when the list is cold and you plan to blast it.
A sale message gets a reply. A reply turns into a sale when someone answers it in time. The message is the easy part. The answer is where the money is.
What does Meta charge for a Black Friday message?
Meta charges per message delivered, and the price depends on the category. A sale offer counts as marketing.
| Category | What Meta says | What it means for your sale |
|---|---|---|
| Marketing | Charged per delivered message. Meta says marketing can include offers and promos, related product suggestions and abandoned cart reminders. | Your sale blast. Count every one. |
| Utility | Not promotional. Triggered by a user action, like an order or a payment. Meta does not charge for utility messages sent in response to a user. | Order updates, yes. A sale ad, no. |
| Service | Sent inside the 24 hour customer service window that opens when a customer messages you. Meta does not charge for it. | Your replies on sale day. |
One more rule: when a customer messages you from a click-to-WhatsApp ad or a Page call-to-action button, Meta says all your messages to that customer are not charged for the next 72 hours.
Do not label a sale blast as a utility message to get a free send. Utility means the customer triggered it.
Who should get a Black Friday WhatsApp message?
People who asked to hear from you. That means buyers, people who joined your list, and people who messaged you.
Everyone else is not on your list, however big the number looks in your export.
Keep a simple record of where each name came from and when they said yes. If someone asks how you got their number, you can answer in one line.
How do I split Black Friday week into three windows?
Give each customer at most three messages in the week. This is my rule, not Meta’s. Three is enough to inform, remind and close.

The 3 Window Plan
One heads up, one sale day, one last call
Stop the sends when the sale stops. Do not keep sending after the offer has ended to see if someone bites.
What do I write? Copy-paste scripts for each window
Change the words in [brackets] and send. Keep the length. Short reads better on a phone.
Window 1 · heads up
Hi [name], it is [brand]. Our Black Friday sale starts Friday 27 November. You asked to hear from us, so you hear the date before anything else. Reply YES if you want the link on the day.
Window 2 · sale day
Hi [name], Black Friday is today at [brand]. [Offer in one line]. Link: [link]. Reply here if you want help choosing. I read every reply today.
Window 3 · last call
Hi [name], Cyber Monday is today and the sale closes at [time] IST. [Offer in one line]. Link: [link].
When someone asks the price
Happy to help. Quick question so I send the right option: what are you shopping for?
What do I do with the orders the replies bring in?
Pack the order the same day you took it, and tell the customer when it leaves. A reply that turns into an order is the moment that decides whether they come back in January.
Set one person to watch the replies on sale day. Do not split the job across five people who each think someone else is answering.
How long can I reply after a customer writes to me?
Meta says a customer message opens a 24 hour customer service window. Replies you send in that window are service messages, and Meta does not charge for them. Each new message from the customer resets the 24 hours.
After that window, a message counts differently under Meta’s rules, so check the rate card before you send one.
How much reply time does Black Friday week need?
Type your own numbers. The tool does the sum. It uses just what you type, and no benchmark.

Send my numbers to Madhur on WhatsAppIf the total is more than your team can carry, cut the list or the number of windows before Friday. Do not promise a reply time you cannot keep.

Questions Indian D2C brands ask about WhatsApp for Black Friday
Do I pay Meta for every Black Friday message?
Meta charges per delivered message in the marketing category. It does not charge for service messages, or for utility messages sent in response to a user. Messages sent in the 72 hours after a click-to-WhatsApp ad are not charged, per Meta. Check the rate card for India rupee figures.
Is a Black Friday offer a utility message?
No. Meta describes utility messages as not promotional and triggered by a user action, such as an order or a payment. A sale offer is marketing.
Can I message people who never asked?
Do not. Write to people who bought from you or asked for updates, and keep a record of when they said yes.
Does Cyber Monday need its own plan?
Use the same three windows. Cyber Monday is Monday 30 November, so the last call goes out that morning.
