Black Friday 2026 is Friday 27 November, and Cyber Monday is Monday 30 November. If you sell to people who already message you on WhatsApp, the work that decides the weekend is done this week: who you may message, what you say, when it goes out, and who answers the replies.
This guide covers those four, with templates you can copy and rewrite. For the two halves that need more setup, see the agent that answers customer questions and the guide to agents, bulk campaigns and Claude.
Who can you message on Black Friday?
Only people who agreed to hear from you. WhatsApp's Business Messaging Policy says you may contact someone only if they gave you their phone number or username and you have their opt-in permission to send them messages. It also says to respect any request to stop, and that WhatsApp may limit or remove access for businesses that get significant negative feedback.
In practice, build the list from people who:
- bought from you before and asked for updates or order messages
- wrote to you first and said yes to offers
- joined through a form or a message where you said you would send sale news
The policy suggests getting opt-in for the kinds of messages you plan to send, such as relevant offers, and making opting out clear. A line in your teaser, like "Reply STOP and I will not message you about sales again", costs nothing and keeps your list clean. A bought or scraped list is the fastest way to get blocked, and Black Friday is the worst week to find out.
What do WhatsApp's own broadcast lists allow?
Less than most sellers expect. WhatsApp's Help Center says broadcast lists hold up to 256 contacts each, and only people who have saved your number in their address book receive the message. Replies arrive as normal one-to-one chats. Broadcast lists are not supported on Windows, Mac or WhatsApp Web.
There is a second limit in some countries. WhatsApp's page on broadcast limits says people in some countries might see a monthly limit, rolling out gradually, of up to 35 free broadcast messages per month. Check yours in Settings, then Broadcasts. If you hit it, plan the teaser, the sale-day message and the last call as three sends, not ten.
Past those limits you need a tool. A Blueticks campaign has no 256-contact list cap and does not depend on each recipient having saved your number. The opt-in rule applies exactly the same. More on the numbers in WhatsApp broadcast limits explained.
What should the Black Friday messages say?
Keep each message to a few lines, one offer, one link, one next step. These five cover the week. Square brackets are yours to fill; {First Name} is a token that fills in each customer's name in a Blueticks campaign.
1. The teaser (about a week before)
Hi {First Name}, it's [your name] from [shop]. Our Black Friday sale starts Friday [time]. You are on the early list, so I will send you the link first. Reply STOP if you would rather not get sale messages.
2. Early access (the day before or the morning of)
{First Name}, the sale opens at [time] today. Early link for you: [link]. [One line on the best offer, e.g. "[X]% off [category]"]. Questions? Just reply here.
3. The sale-day message
It's live, {First Name}. [Offer in one line]. Ends [day, time]. [Link]
4. The last call (the final hours)
Last few hours, {First Name}: the [offer] ends at [time] tonight. [Link]. If you have a question before you buy, reply and I will answer.
5. The Cyber Monday follow-up (only to people who did not buy)
Hi {First Name}, the weekend offer on [product] runs until [time] today. [Link]. Happy to help if you are deciding between two options.
Write them in your own voice. Replace the brackets with real numbers and times, state the actual end time, and never promise stock you do not have. If a message promises a deadline, honor it.
When should the messages go out?
WhatsApp does not publish a best time to send, and we do not claim one. Use your own data: look at when customers last wrote to you and when your last offer got replies. A calendar to start from:
| When | What | Who |
|---|---|---|
| This week | Collect opt-ins; write and test the five messages | You |
| About 7 days before (Friday 20 November) | Teaser | Opted-in list |
| Thursday 26 November, evening | Early access | Opted-in list |
| Friday 27 November, morning | Sale is live | Opted-in list |
| Friday 27 November, a few hours before the deadline | Last call | Opted-in list |
| Monday 30 November | Cyber Monday follow-up | Non-buyers only |
Two rules matter more than the exact hour. Send in your customers' local daytime, not yours, and do not send the same list more than the sale needs. Each extra message is another chance for someone to tap Block.
How do you schedule the whole run in advance?
Write the messages now and schedule them, so the sale does not depend on you being at your phone.
- A few important contacts. Use the scheduler to set a message for a date and time on a chat. See how to schedule WhatsApp messages for the steps.
- A whole list. Create a campaign with your audience and message, personalize it with
{First Name}, and set the start date and time. Campaign sends are spaced out by default rather than going out all at once. - Test first. Make an audience that contains only your own number, send each message to it, and read it on your phone before the real audience gets it.
Know the platform rules. WhatsApp's Terms of Service say you must not access or use the Services through automated or other means in impermissible or unauthorized manners. The same Terms list "bulk messaging, auto-messaging" among impermissible communications, so there is real risk in blasting anyone who did not ask to hear from you. Send only to people who opted in (see above), keep the volume to what the sale needs, and stay away from apps that promise unlimited blasts or run extra numbers through unofficial methods. WhatsApp's Business Messaging Policy says it may limit or remove access for businesses that get significant negative feedback.
One thing to check before you rely on a schedule: Blueticks sends from the WhatsApp connection on your account, and that connection must be online at send time. On the Basic and Standard plans Blueticks runs in your browser, so it needs Chrome or WhatsApp Web open and your computer on. On the Pro plan the connection is cloud-hosted and keeps working with your computer off. See pricing for current plans. If your plan runs in the browser, leave the computer on and the tab open through each send.
Who answers the replies?
Every good Black Friday message produces replies: "is this still available?", "does the code work on sale items?", "where is my order?" They arrive in bursts, and a slow answer is a lost sale.
An AI agent on your own number can cover the repeat questions from text you write, and step back when you type in a chat yourself. You describe it in plain words and it is built in about a minute. Load your answers for sizing, shipping, returns and the offer terms, switch on the answer-only option, and test it from a second phone. It cannot look up an order or take a payment, so send those to a person. Like scheduled sends, it answers only while your connection is online: on Basic and Standard that means Chrome and WhatsApp Web open and your computer on, while Pro keeps working with the computer off. The settings are in the Black Friday customer questions guide, and the WhatsApp AI agent guide covers the options for building one.
A short checklist for this week
- List who opted in, and remove anyone who asked you to stop.
- Fill in the five messages with real offers, times and links.
- Check whether you have a monthly broadcast limit in Settings, then Broadcasts.
- Schedule the sends, and test each on a list of one.
- Confirm the connection will be online at every send.
- Decide who answers replies on 26 to 30 November.
FAQ
Can I send a Black Friday message to everyone in my contacts? Only to people who agreed to hear from you. WhatsApp's Business Messaging Policy says you may contact people only if they gave you their number and opted in to messages from you, and WhatsApp can limit or remove access for businesses that get significant negative feedback.
How many people can I message with a WhatsApp broadcast list? Up to 256 contacts per list, and only the ones who saved your number receive it. In some countries WhatsApp also shows a monthly limit of up to 35 free broadcast messages. Check Settings, then Broadcasts, to see yours.
Can I schedule Black Friday WhatsApp messages in advance? Not with WhatsApp alone. Its own scheduler is only in beta for some testers. With Blueticks you can schedule messages on chats and set a start date and time for a campaign, as long as your connection is online at send time.
Will my scheduled messages send if my computer is off? It depends on the plan. On Basic and Standard, Blueticks runs in your browser, so sending stops when Chrome or WhatsApp Web is closed or the computer is off. On Pro, the connection is cloud-hosted and keeps working with your computer off.
What is the best time to send a Black Friday WhatsApp message? WhatsApp does not publish one. Use your own chat history to see when your customers write to you, send in their local daytime, and keep the number of messages to the minimum the sale needs.
Can an AI agent answer Black Friday questions for me? Yes. An agent on your own number can answer repeat questions from text you write and pause in any chat where you start typing. It cannot look up orders or take payments, so those go to you.
