Why your own customer list beats followers

For each customer on it, you hold:

• a name, so you know them as a customer and not only as a handle or a phone number;
• a way to reach them when you have something to say, without waiting for them to write;
• their permission, given by them for the kind of thing you send, and theirs to take back;
• their history with you: when they last came, how often, what they have earned and used.

Check each channel you use against those four.

The rules behind the first three columns are the platforms' own, read on 9 October 2026 and quoted below. We found no study that measures what such a list is worth to a small shop in sales, so the case rests on the rules.

Instagram's own account of how it ranks what people see, published in May 2023, describes a person's feed as "a mix of content from the accounts you've chosen to follow, recommended content from accounts we think you'll enjoy and ads." Posts are ranked for each person, and one signal is "Your history of interacting with someone".

So a post reaches the followers Instagram judges to be interested, mixed with recommendations and advertising, and you do not choose which. A follower count does not say who has bought from you either: a regular and a competitor each count as one.

Meta publishes rules for software that sends messages on a business's behalf. The main one: "Businesses have up to 24 hours to respond to a user." A comment allows one private message in return, within seven days, and nothing more unless the person answers. How to turn comments and messages into members shows how to use that one message well.

WhatsApp's Business Platform, the service that messaging software connects to, works the same way and adds a price. A customer's message opens a 24-hour window in which replies are free. Outside it a business can send only a template message, charged for on delivery: "All marketing template messages are charged." Meta publishes the rates, which vary with the kind of message and the customer's country code. Check them before you budget for a broadcast. The terms change, too: the earlier model, a charge for each conversation, "was replaced with per-message pricing on July 1, 2025."

WhatsApp's messaging policy, which covers the WhatsApp Business app as well as the Platform, adds a condition. You may contact people only if they gave you their number or username and you have "received opt-in permission from the recipient". A number saved from an old order is not that permission.

So the customer starts the conversation, and a day later your chance to reply ends. On Instagram and Messenger a tool working for you can answer but cannot start one. On WhatsApp you can start one, with people who opted in, and you pay for each message.

Grab's Code of Conduct for its merchants in Malaysia says: "Merchants contacting delivery partners or consumers outside of the Grab Merchant App for unwarranted purposes is strictly prohibited and considered a form of harassment and breach of personal privacy." It also asks merchants "not to solicit or poach consumers to order outside of the Grab Merchant App."

The page does not say what would be warranted, and a promotion is hard to read that way. It is a fair rule for a platform to make: the customer gave their details to the app, for an order. Other platforms have their own terms. Read yours before you slip anything into a bag.

None of this is a reason to stop posting. A list holds only people who already know you, and it cannot reach a stranger. The platforms can. DataReportal's report on Malaysia, drawing on Meta's advertising tools, puts Facebook's advertising reach at 23.0 million people in late 2025 and Instagram's at 16.1 million, in a population of 36.1 million. Those are the people an advertiser can pay to reach, and the report warns that they "are not the same as the active user figures" Meta reports to investors.

The platforms are where people find you, and the list is where you keep them. A post brings someone to your counter once. The counter, or your one reply to their comment, is where you offer them the way onto your list.

The homepage puts it in one line: "Build a customer list you own, and reach it without paying per message."

A name. A customer scans your sign or opens your link, confirms an email address with a 6-digit code and adds your card to Apple Wallet or Google Wallet. In setup, What do you ask when they join? warns: "Every extra question loses a few people." The name is worth asking for, because a member who gives none appears in your list as Unnamed customer. Add Phone only if, in the form's words, "you need to ring or message them."

A way to reach them. Notifications sends "to your customers’ phones through the card they keep in Apple Wallet or Google Wallet": to Everyone, New members or Members with a reward waiting. Nobody has to write first. On cost: Zero notification fees.

Their permission. Joining takes one tick, for your terms and privacy notice. If your program has wording for offers, a second appears: "Send me offers and news in Wallet." It is optional and starts unticked, and an offer "Only reaches members who agreed to offers." Reward reminders and news about your business reach every card holder.

Their history. Customers lists "Everyone who has joined, grouped by how recently they visited and by what is worth doing next." Each row shows Last visit, Value (spend and visits) and Card (progress to the next reward). A member's own page lists every purchase recorded at the counter and every reward earned or used. Only the owner and admins can open it. Counter staff get the scanner.

So your list has three sizes. Home shows them under Audience:

• Members: the total.
• Have your card: "Members with an active Wallet Card".
• Can get offers: "Card holders with offer notifications on."

For an offer, the last is the one that counts.

Only people who joined are on it. Each member confirmed their own email. You cannot upload old contacts or a spreadsheet. That is slower, and it is why every name belongs to someone who chose to be there.

You reach them through the card. Email is asked "so a member can sign in and get a lost card back". There is no download of the member list, though Activity History has Export for Excel for what each member earned and used. Nothing is sent by WhatsApp or SMS. If your customers prefer a chat, your Business page can carry a Help link to your WhatsApp chat, and a member who uses it writes first.

The member can leave. In their membership on your Business page they can switch offers off under Your choices here, or press Close membership. In their Wallet they can silence the card or remove it: the Notifications page says "Apple and Google deliver only while the card is still in their Wallet".

There is a ceiling. A card takes at most three notifications in 24 hours, and the wording carries no links. New wording is checked by native.cards before it goes out, so write a notice ahead of the day you need it. The three audiences are the only ones: you cannot write to one person, or only to those who have stopped coming. How often should you send notifications? covers how to use that room.

A list you hold is also one you answer for: see Your members' personal data: what the law expects.
