NewUpcomingCustomers subscribe to your WhatsApp marketing in one tap.
WhatsApp In-App Signup replaces the form, the checkbox and the keyword reply with a single screen inside WhatsApp itself. A customer taps your link, sees exactly what you’ll send, confirms once — and they’re a consented subscriber before they’ve left the app.
Meta built it because marketing on WhatsApp lives or dies on consent quality. Every step between “interested” and “subscribed” loses people — and a list built from implied consent is the fastest way to lose the ability to send at all. This removes nearly every step, and makes the consent explicit at the same time.

In short
The shortest path from interest to consented subscriber that WhatsApp allows.
What it does
Turns a tap on a link into a consented WhatsApp marketing subscriber, with the consent screen and confirmation handled by WhatsApp itself.
Who it's for
Any business that markets on WhatsApp and currently collects opt-in through forms, checkboxes or keyword replies — and loses people at every step.
Why it matters
Opt-in rate and consent quality are the two things that decide whether WhatsApp marketing works. This improves both at once, which is rare.
How it's different
Traditional opt-in happens somewhere else and asks the customer to prove who they are. This happens inside WhatsApp, where they already are and are already identified.
The customer journey
Eight steps, and the customer only does two
Everything else is handled by WhatsApp or by you, before the campaign ever goes live.
- 01
You design the signup experience
Write the one-line pitch customers see before they subscribe, the thank-you message they get the moment they do, and link your privacy policy. Optionally attach a welcome code.
- Why it helps you
- The offer, the confirmation and the incentive are decided once, up front — not improvised per campaign.
- What the customer feels
- Nothing yet. This step is entirely on your side.
- 02
You share the link
You get a WhatsApp link to put anywhere you already reach people — your site, an ad, a QR code on packaging, a store counter, an email footer, a bio link.
- Why it helps you
- One link works across every channel you already run. It isn't tied to a single phone number, so any number on your account can carry it.
- What the customer feels
- A normal-looking link or QR code, in a place they already trust.
- 03
The customer taps it and WhatsApp opens
No landing page, no form, no app install, no account creation. The link opens straight into WhatsApp.
- Why it helps you
- You skip the single biggest source of drop-off in opt-in collection: sending someone to a web form.
- What the customer feels
- WhatsApp opens instantly — an app they already have and are already signed into.
- 04
They see exactly what they're agreeing to
Before anything is confirmed, WhatsApp shows a consent screen with your business name, your description of what you'll send, and a link to your privacy policy.
- Why it helps you
- Consent is explicit, informed and recorded by WhatsApp itself — the strongest position you can be in when opt-in quality is questioned.
- What the customer feels
- A clear, native screen that looks like WhatsApp, not like your marketing. That familiarity is what earns the tap.
- 05
They confirm
One tap. That's the entire commitment — no email, no phone number to type, no password, no verification code.
- Why it helps you
- Opt-in becomes a single tap instead of a multi-field form, which is where conversion is won.
- What the customer feels
- Done in under a second, without leaving the conversation.
- 06
WhatsApp sends your confirmation instantly
Your thank-you message is delivered the moment they subscribe — automatically. If you attached a welcome code, it appears right there in the message.
- Why it helps you
- You land in their chat list at the exact moment of highest intent, and an incentive arrives before enthusiasm cools.
- What the customer feels
- Immediate acknowledgement, and often a reward. The subscription feels worth it straight away.
- 07
They join your subscriber list
The new subscriber is added to a subscriber list on your account automatically. You're notified in real time, so your own systems stay in sync.
- Why it helps you
- No manual export, no CSV, no reconciliation. The list is authoritative from the first second.
- What the customer feels
- Invisible — and that's the point.
- 08
You can market to them
They are now a consented marketing subscriber. Future campaigns go to an audience that actively chose to hear from you.
- Why it helps you
- Higher open and reply rates, lower block rates, and a healthier sender quality rating over time.
- What the customer feels
- Messages they expected, from a business they chose. The difference in tone is immediate.
The difference
Where the old way loses people
Collecting opt-in the usual way
- Customer leaves the channel they were in
- Lands on a web form on a slow mobile connection
- Types a phone number, often with a country-code mistake
- Waits for an OTP, switches apps to read it
- Ticks a consent box they did not read
- You hold consent you would struggle to evidence
With In-App Signup
- Customer taps a link and stays inside WhatsApp
- Sees your business name and exactly what you will send
- Nothing to type — WhatsApp already knows who they are
- One tap confirms
- Your privacy policy was on screen at the moment of consent
- Confirmation and welcome code arrive instantly
Everything it does
The full feature set, in plain language
What each capability is, why it exists, when to use it, and what that looks like in practice.
Signup links
A WhatsApp link that opens the subscribe flow directly inside the app.
- Why it exists:
- Every other opt-in route — web form, keyword reply, checkbox at checkout — asks the customer to do work somewhere else. This one doesn't.
- When to use it:
- Anywhere you currently ask people to 'join our WhatsApp updates'.
ExampleA D2C brand prints a QR code on the inside of every shipping box. Scanning it opens WhatsApp on the subscribe screen.
The consent screen
A native WhatsApp screen shown before anyone subscribes, carrying your business name, your description and your privacy policy link.
- Why it exists:
- Consent has to be informed to be worth anything. WhatsApp presents it in an interface customers already trust.
- When to use it:
- Always — it isn't optional, and it's the reason opt-in quality is high.
ExampleA clinic writes: 'Appointment reminders and health camp invites. About 2 messages a month.' Expectations are set before the tap.
Confirmation messages
A message you write once, delivered automatically the instant someone subscribes.
- Why it exists:
- The moment right after opt-in is the highest-intent moment you will get. Silence wastes it.
- When to use it:
- Every signup experience. Use it to set expectations or deliver a reward.
Example'Welcome to Kova Living! You'll hear from us about new drops and restocks — roughly twice a month.'
Welcome codes
A promotional code you can embed in the confirmation message, delivered automatically on subscribe.
- Why it exists:
- It converts an abstract 'subscribe' ask into a concrete, immediate trade.
- When to use it:
- Whenever you need a reason for someone to opt in right now rather than later.
ExampleA restaurant offers a first-order code in the confirmation. The subscription pays for itself on the same visit.
Business identity
Your business name and website shown as part of the experience, so customers know exactly who they're subscribing to.
- Why it exists:
- Anonymous opt-in requests get ignored. Recognisable ones get accepted.
- When to use it:
- Always — trust is the whole conversion mechanism here.
ExampleA customer sees the brand they just bought from, not an unfamiliar number.
Multiple signup campaigns
As many separate signup experiences as you need, each with its own wording and incentive.
- Why it exists:
- A festival campaign, an in-store QR and a website banner deserve different pitches — and you need to know which one worked.
- When to use it:
- Whenever you want to tell two audiences apart, or A/B a pitch.
ExampleA retailer runs one link for in-store QR codes and another for Instagram bio, then compares which drives better subscribers.
Subscriber lists
Organised groups your subscribers land in. Your first one is created for you; you can add more and choose which is the default.
- Why it exists:
- One undifferentiated list forces you to send everyone the same thing, which is how unsubscribes start.
- When to use it:
- As soon as you have more than one kind of customer.
ExampleA finance brand keeps existing-customer and prospect subscribers in separate lists so offers never cross over.
Editing a live campaign
Update the pitch, the confirmation message, the welcome code or your website at any time, without reissuing the link.
- Why it exists:
- Campaigns need to be tuned while they run, and reprinting a QR code is not an option.
- When to use it:
- Seasonal refreshes, changed offers, or fixing a pitch that isn't converting.
ExampleThe printed QR stays the same all year; the code behind it changes from DIWALI20 to NEWYEAR15 overnight.
Pausing a campaign
Switch a signup experience off when a promotion ends, and switch it back on later.
- Why it exists:
- An expired offer that still accepts subscribers creates a customer-service problem.
- When to use it:
- The moment a time-boxed promotion closes.
ExampleA travel brand pauses its monsoon-sale link in September and reopens it the following year.
Privacy policy — required, and permanent
A link to your privacy policy is mandatory, shown on the consent screen, and fixed once the campaign is created.
- Why it exists:
- It is what makes the consent legally meaningful.
- When to use it:
- Decide it before you create anything — this one genuinely cannot be changed afterwards.
ExamplePoint it at a stable URL like /privacy that you control, never at a campaign-specific page you might retire.
What changes
Why this moves the numbers
Higher opt-in rates
One tap inside an app they already trust, versus a web form asking for a phone number. The difference shows up immediately in how many people finish.
Frictionless onboarding
No landing page, no form fields, no OTP, no account creation. The shortest path from interest to subscriber that WhatsApp allows.
Consent you can stand behind
Explicit, informed and captured by WhatsApp itself, with your privacy policy on screen at the moment of agreement.
Better campaign performance
An audience that actively chose you opens more, replies more and blocks less than a list assembled from checkout checkboxes.
Incentive at the perfect moment
A welcome code lands the instant someone subscribes — while intent is at its peak, not in a follow-up nobody opens.
Subscriber management that keeps up
Subscribers arrive in organised lists automatically, and your systems are notified in real time. No exports, no reconciliation.
A native WhatsApp experience
It looks and behaves like WhatsApp because it is WhatsApp. Nothing about it feels like a marketing funnel.
Fewer drop-offs
Every screen you remove between interest and subscription is a place people stop leaving. This removes nearly all of them.
Cleaner compliance posture
Opt-in is recorded against a consent screen that named you and linked your policy — a materially stronger record than a pre-ticked box.
Trust that compounds
People who chose to hear from you stay subscribed longer, which protects the sender quality rating everything else depends on.
By industry
Where the link goes, and what you send after
The moment that earns the subscription is different in every business. These are the ones that work.

A QR code inside the delivery box, and a link on the order-confirmation page.

Restock alerts, new drops and sale previews to buyers who already trust the brand.
D2C brands
Where the link goes

What you send after

Education
Where the link goes
On the enquiry page and at every open day or counselling session.

Service-due reminders, exchange offers and new-model previews to owners and prospects.
SaaS & technology
Where the link goes
In the product itself, and at every webinar or event booth.
What you send after
Feature launches and onboarding nudges on a channel with far better reach than email.
Agencies
Where the link goes
Run separate signup experiences per client, each with its own pitch and incentive.
What you send after
A measurable, ownable audience per client — and a service line that renews.
Worth knowing up front
The constraints that catch teams out
None of these are dealbreakers. All of them are easier to plan for than to discover after a campaign is printed on packaging.
Your privacy policy link is permanent
It cannot be changed after a signup experience is created. Point it at a stable page you control — not a campaign microsite you may later retire.
Campaigns are paused, never deleted
You can switch a signup experience off and on again, but it stays on your account. Plan naming accordingly so an archive of old campaigns stays readable.
A paused link shows an error
Customers who tap a switched-off link see an error rather than a friendly message. Retire printed QR codes deliberately, and don't pause a link that's still in market.
Both messages are short
The pitch on the consent screen and the confirmation message are capped at 300 characters each. That is a feature — it forces clarity — but write to it rather than against it.
Welcome codes are letters and numbers only
No spaces, dashes or symbols, up to 50 characters. Check your existing promo-code format before you plan a campaign around it.
You accept Meta's terms once
A one-time acceptance covers your business. It is not a per-campaign step.
Timing
Subscriber lists compound. Starting late is the expensive part.
Every channel that has mattered on the internet has followed the same arc: an early window where attention is cheap and organic reach is real, then a long period where it is neither. WhatsApp marketing is early in that arc, and a consented subscriber list is the asset that survives it.
The businesses that will do well are not the ones with the best campaign in 2027 — they are the ones who spent 2026 building an audience that actually chose them.
Cheap attention now
Opt-in prompts are still novel on WhatsApp. Subscription rates for early adopters are higher than they will be once every brand is asking.
A list you own
Unlike social followers, a consented subscriber list does not depend on an algorithm deciding to show your post.
Sender quality protected
Building on clean, explicit consent from day one avoids the quality-rating damage that forces businesses to rebuild later.
Compounding advantage
A competitor starting a year behind is not a year behind on tooling — they are a year behind on subscribers, which cannot be bought back.

FAQ
Frequently asked questions
What is WhatsApp In-App Signup?
It is a way for customers to subscribe to your WhatsApp marketing messages by tapping a link that opens directly inside WhatsApp. They see a consent screen explaining who you are and what you will send, they confirm with one tap, and they immediately receive a confirmation message from you. No web form, no app install, no account creation.
How is this different from how we collect WhatsApp opt-ins today?
Most opt-in today happens somewhere other than WhatsApp — a checkbox at checkout, a web form, a keyword reply, or an assumption based on a past purchase. Each of those adds a step, and every step loses people. In-App Signup collects consent inside WhatsApp itself, in one tap, with your privacy policy on screen at the moment of agreement.
Why did Meta introduce this?
Marketing messages on WhatsApp require genuine consent, and the quality of that consent determines whether a business can keep sending. Meta needed an opt-in method that was both frictionless enough that customers actually complete it, and explicit enough to be defensible. Putting the consent screen inside WhatsApp achieves both.
Do customers need to install anything or create an account?
No. The entire flow happens inside the WhatsApp app they already have and are already signed into. There is nothing to install, no form to fill, no password and no verification code.
Where can we put the signup link?
Anywhere you already reach people: your website, ads, a QR code on packaging or in-store signage, an email footer, a social bio, or a printed receipt. The link is not tied to a single phone number, so any number on your WhatsApp Business account can carry it.
Can we give people an incentive for subscribing?
Yes. You can attach a promotional code that is delivered automatically inside the confirmation message the instant someone subscribes. Codes are letters and numbers only, up to 50 characters.
Can we run more than one signup campaign?
Yes, and most businesses should. Separate campaigns let you word the pitch differently for different audiences — an in-store QR code and an Instagram bio link deserve different copy — and let you tell which source produced better subscribers.
How are subscribers organised?
Subscribers are added to a subscriber list on your account automatically. Your first list is created for you, and you can create additional lists and choose which one new subscribers join by default — useful for keeping prospects and existing customers apart.
Can we change a campaign after it goes live?
Most of it, yes. The pitch, the confirmation message, the promotional code and your website link can all be updated at any time without reissuing the link — so a printed QR code can stay in market while the offer behind it changes. The one exception is your privacy policy link, which is permanent.
Why can't the privacy policy link be changed?
Because it is part of the consent your subscribers already gave. Allowing it to be swapped later would undermine the record. Point it at a stable page you control rather than a campaign-specific one.
How do we stop a campaign?
You switch it off, and you can switch it back on later. Campaigns are not deleted. Note that customers who tap a switched-off link see an error rather than a friendly message, so retire printed QR codes deliberately.
Is a privacy policy mandatory?
Yes. A link to your privacy policy is required and is shown to customers on the consent screen before they subscribe. There is also a one-time acceptance of Meta's terms that covers your business — it is not a per-campaign step.
How long can the messages be?
Both the description on the consent screen and the confirmation message are capped at 300 characters. In practice this is helpful: the businesses seeing the best results are specific about what they will send and how often.
Does this replace our other opt-in methods?
It does not have to. Existing opt-in routes keep working. In-App Signup is the lowest-friction option available, so most businesses make it the primary route and keep the others as fallbacks.
Will this improve our message delivery?
Indirectly, and meaningfully. Subscribers who actively chose you block and report far less than audiences assembled from implied consent. Because WhatsApp's sender quality rating responds to exactly those signals, a cleaner opt-in source protects your ability to keep sending.
Is In-App Signup available in InfiQ today?
Not yet. It is on our roadmap and this page describes how it will work. If you want to be among the first accounts enabled when it ships, talk to us and we will add you to the early-access list.
