Chat-ins Overview: How to Grow Your WhatsApp Subscriber List
Growing your WhatsApp channel starts with one key question: how do people opt in? Chat-ins are the entry points that bring subscribers into your WhatsApp list, and choosing the right mix of them is one of the most important strategic decisions you'll make when setting up your WhatsApp marketing.
What Are Chat-ins?
Chat-ins are entry points that allow your customers to start a conversation with your brand on WhatsApp.
Every subscriber in your WhatsApp list came through a chat-in. That's why having the right entry points in place is foundational to your WhatsApp growth strategy: no chat-ins, no subscribers. No subscribers, no revenue.
💡 Think of chat-ins as the front doors to your WhatsApp channel - the more doors you open in the right places, the faster and more consistently your audience grows.
How to Think About Chat-ins
Not all chat-ins are the same. To choose the right ones for your business, it helps to evaluate them across two dimensions: where they live and how they collect subscribers.
By Placement & Target Audience
Different chat-ins reach people at different moments in their journey with your brand. Here's how they break down:
Placement | Channel Examples | Target Audience |
🌐 Website - Before Purchase | Pop-up, banner, footer, bubble, topbar | New visitors and potential customers |
✅ Website - After Purchase | Thank You page | Recent buyers and existing customers |
📧 Other Online Channels | Email, Social Media | Existing audiences and followers |
📱 Offline | QR Codes, Leaflets | In-store shoppers, event attendees, offline traffic |
The key insight here is that different placements reach different people at different intent levels. A new visitor on your homepage is in a very different mindset than a customer who just completed a purchase, and your chat-in strategy should reflect that.
By Subscriber Collection Type
Beyond placement, chat-ins also differ in how they fit into your growth strategy over time:
| 🔄 Ongoing Collection | 🚀 One-time Collection |
What it is | Always-on entry points that collect subscribers continuously | Temporary entry points activated for a specific campaign or moment |
Best for | Sustainable, long-term subscriber growth | Boosting growth during launches, seasonal campaigns, or key events |
Key rule | Minimum of 2 ongoing chat-ins recommended for consistent collection | Ideal as a complement to your ongoing setup, not a replacement |
A healthy WhatsApp growth strategy combines both types: ongoing chat-ins form the backbone of your subscriber collection, while one-time chat-ins give you a boost when it matters most.

Dive deeper into each chat-in to understand how it works and how to set it up:
🌐 Website Pop-Up Capture new visitors while they browse your site with an always-on WhatsApp opt-in widget. Perfect for top-of-funnel subscriber collection. → Create a Pop-Up.
💬 Bubble
Sits in the corner of your website, always visible and just one click away. It's one of the easiest entry points to configure directly in charles. You can also activate it for specific campaigns or events for an extra growth boost. → Create a Chat Bubble.
✅ Thank You Page Turn buyers into WhatsApp subscribers right after checkout. This is one of the highest-converting entry points because customers are already engaged. → Create a Thank You Page Entry Point.
📣 Click-to-WhatsApp Ads Run paid ads on Facebook or Instagram that open a WhatsApp conversation directly. Great for reaching new audiences or re-engaging existing ones. → Create Click-to-WhatsApp Ads.
📲 Social Media Organic
Share your WhatsApp link directly through your organic social media presence — in your Instagram bio, feed posts, or stories. No ad budget needed. It's a simple and effective way to convert your existing followers into WhatsApp subscribers. Use it as a permanent touchpoint in your bio for ongoing collection, or activate it around specific campaigns and moments for a targeted boost. → Convert Social Media Follower to WhatsApp.
📧 Email Chat-in Add a WhatsApp opt-in link to your email campaigns and newsletters to convert your existing email list into WhatsApp subscribers. → Convert Email Subscribers to WhatsApp.
📱 QR Code Place QR codes in-store, at events, or on packaging to bring offline audiences into your WhatsApp channel.
🔗 Landing Page Create a dedicated opt-in page that can be shared across any channel, online or offline, to drive subscribers at scale.
How Many Chat-ins Do You Need?
There's no one-size-fits-all answer, but here's a simple framework to guide your thinking:
Start with at least 2 ongoing chat-ins. This ensures you're collecting subscribers consistently, even when you're not running active campaigns. A website widget combined with a Thank You page is a strong starting point for most e-commerce brands.
Layer in one-time chat-ins for key moments. Planning a product launch, a seasonal sale, or a brand event? Add a temporary chat-in to maximize subscriber growth during that window.
Diversify your placements over time. The more touchpoints you cover - website, email, social, offline - the broader and more resilient your subscriber base becomes.
⚠️ We recommend a minimum of 2 ongoing entry points to ensure consistent subscriber collection. Relying on a single chat-in creates a single point of failure in your growth strategy.
