What is WhatsApp marketing?

WhatsApp marketing means sending promotional messages, order updates, and personalised campaigns to your customers directly on WhatsApp. It allows Shopify brands to reach customers in a channel they already use daily, resulting in higher engagement and open rates compared to traditional channels.

How is WhatsApp marketing different from SMS?

Both reach customers on their phones, but WhatsApp offers a richer experience. You can send images, videos, product catalogues, and clickable buttons within messages. Customers can also reply and engage in real conversations with your brand. SMS is limited to one way text only, while WhatsApp is interactive and two way.

What are the three WhatsApp message types?

WhatsApp supports three official message types. Marketing messages are used for promotions, campaigns, and re engagement. Utility messages handle transactional updates such as order confirmations and shipping notifications. Authentication messages are used for one time passwords and verification. Mergn supports all three from a single platform.

Is bulk WhatsApp marketing allowed?

Yes, but only if your customers have explicitly opted in to receive messages from your brand. WhatsApp requires user consent before sending marketing messages. Mergn manages opt ins and opt outs automatically, helping you stay compliant while running campaigns at scale.

What is the WhatsApp AI chatbot Mergn is building?

The Mergn WhatsApp AI is an always on assistant trained on your Shopify store, product catalogue, and brand voice. It can answer product questions, recommend items, and guide customers through the purchase journey without human involvement. It is currently in development and will be available soon.

How does WhatsApp connect to my Shopify store?

When you connect Shopify to Mergn, your product catalogue, customer list, order history, and behavioural data all sync automatically. WhatsApp campaigns use this data to personalise every message, so each customer sees their name, past orders, and relevant product recommendations. Triggered messages are sent automatically based on customer actions in your store.

Shopify WhatsApp marketing that drives real sales

BULK WHATSAPP MARKETING

Campaigns that feel like a message from a friend.

WhatsApp messages land next to personal conversations, not in a promotions tab or spam folder. That is why even a simple campaign on WhatsApp consistently outperforms the same message sent by email.

Bulk WhatsApp campaigns

Send personalised WhatsApp messages to thousands of opted-in customers at once. Each message includes their name, order history and a custom offer generated automatically.

Smart Send for WhatsApp

WhatsApp costs more per send than email. Smart Send makes every message count by filtering your list to customers most likely to respond before each campaign goes out.

Rich media messages

Add product images, videos and clickable buttons directly inside your WhatsApp message. More context means more engagement and higher conversion.

UTILITY MESSAGES

The WhatsApp messages your customers are already waiting for.

Order updates and delivery confirmations on WhatsApp are opened almost every time. They're not interruptions, they're updates your customers expect. Each message keeps them informed and strengthens their trust in your brand.

Order and shipping updates

Order confirmed, dispatched and delivered messages sent automatically over WhatsApp. Fewer support tickets, happier customers at every step.

Back-in-stock notifications

The moment a product comes back in stock, customers who requested a notification get a WhatsApp message instantly. No delay, no manual work.

Abandoned cart recovery

A personalised WhatsApp message sent to someone who left items behind consistently beats email on both open rate and conversion rate for Shopify stores.
