How WhatsApp Marketing Messages Work for E-commerce?

See how the WhatsApp marketing messages work for an e-commerce brand step by step!

Step 1: Customer Gives Permission (Opt-in)

To send any kind of marketing messages, the customers need to give permission for that. And how did the customer do this? This happens when they:

• Complete a form on the brand’s site.
• Place an order and select to get updates.
• First, send a message to your WhatsApp number.
• Click the start chat on the brand’s social media platform.

When businesses have the right opt-in procedures, the engagement rate is 40% higher than when the company does not have consent.

Step 2: Create Message Templates

Now, every time, a business can create a unique message to send to a number of customers. So, what they do is they create message templates that WhatsApp approves. These templates have:

• Fixed text that doesn't change
• Variables like customer name or order number
• Call-to-action buttons
• Media attachments (images, videos, documents)

After creating the templates, they get verified by WhatsApp; typically, it takes around 24-48 hours to get approved. And almost 85% of the well-crafted templates get approval.

Step 3: Send Personalised Messages

With the WhatsApp marketing messages API, you can send personalised messages to your customer list. Each message is personalised with:

• Customer's name
• Their order details
• Relevant product recommendations
• Location-specific offers

Step 4: Meta's Smart Delivery

Now, you might be thinking, how do you know when to send these messages?

So, don't worry, this task is also handled by the WhatsApp messages marketing API.

It identifies the most appropriate time to deliver messages to individual customers, and there is a high possibility of users opening and reading the messages.

It also regulates the frequency of sending messages and thus gives the brand a chance to evade spamming or annoying users.

The system enhances the relevancy of the content since it utilises customer behaviour, and hence, people are presented with messages that are actually relevant to them.

More than that, it selects the most optimal delivery routes, and, therefore, messages are delivered fast and with high reliability to the customers.

Step 5: Track Performance

With the WhatsApp marketing messages API, you are also able to see detailed analytics about:

• How many messages were delivered?
• How many were opened and read?
• Click-through rates on links and buttons
• Customer responses and engagement

Let us tell you about a real example of a fashion brand, Snitch! This fashion brand has partnered with Pragma WhatsApp Business Suite and has achieved 73% open rates and 4% click-through rates using it. Not only this, but with the help of this system, it gets around ₹9.5 crore in cost savings in one fiscal year.

What are the Benefits of Using WhatsApp Marketing Messages API?

‍

If an e-commerce D2C brand uses the WhatsApp marketing messages API, it will get the following benefits:

It has High Message Open Rates.

WhatsApp marketing messages API has an index of up to 98% open rate, which implies that nearly all customers will actually look at your message.

Compared to the emails, which were easily lost in spam or never opened, WhatsApp messages will always be shown on the phone of the user, which will never be missed.

This assists the brands in conveying their message without fighting for the customer's attention.

It Helps in Faster Customer Engagement

WhatsApp messages are read in a few minutes after they are delivered. This is why it is ideal in time-sensitive communication such as flash sale, time offer, payment reminders or a delivery update.

Customers are also able to respond immediately, which provides faster and more natural conversations.

It aids in Increased Conversion and Sales.

In most cases, WhatsApp marketing has been shown to achieve 3-5 times the conversion rate of email or SMS.

Messages are more personal, and they motivate the customers to make purchases, particularly in the case of abandoned carts, repeat purchases, and personalised suggestions.

The brands which used Pragma WhatsApp Business Suite have seen 11x return on their Ad spend through promotions via WhatsApp.

It Can Easily Automate at Scale

Through the API, e-commerce brands are able to automate order confirmations, shipping notifications, COD validation, payment reminders and promotional messages.

This minimises labour costs, is time-saving, and enables the brands to handle thousands of customers with ease.

Pragma helps to automate approximately 75% of the work, which gives a 451% increment in qualified leads.

It Develops Trust and Customer Loyalty

Indian consumers have a lot of trust in WhatsApp. By advertising on such a familiar platform, the customers will feel more at ease, and this enhances trust, satisfaction and a long-term commitment to the brand.

It is a Cost-Effective Form of Marketing

The WhatsApp Marketing Messages API is significantly cheaper to use in comparison with most of the traditional marketing channels.

WhatsApp messages are less expensive and achieve higher results compared to SMS, paid ads, or influencer campaigns.

This implies that e-commerce businesses will be able to access a larger number of customers, get more carts, and make more sales without necessarily having to spend more on marketing.

Brands using Pragma WhatsApp Business Suite have seen a decline in their operational costs by almost 40%, along with the 15% increase in conversions.

It Offers Rich Media Support

‍

WhatsApp also allows rich media content, and this facilitates more engaging and understandable messages. It can send images, videos, product catalogues, buttons, links and even payment prompts.

Customers do not have to read long text, but can look at the product images, view short videos, or press quick-reply buttons.

This enhances the customer experience, and in most cases, it increases the number of visits and purchase rates, particularly when it comes to promotions, launching new products and updating orders.

With Pragma WhatsApp Business Suite, you can showcase your products in a catalogue in an easy-to-browse manner, along with their prices and descriptions on a single WhatsApp page.

What can be the Use Cases of WhatsApp Marketing Messages API for e-commerce Brands in India?

Abandoned Cart Recovery

‍

E-commerce brands are able to send subtle reminders through WhatsApp when the customer leaves items in their cart.

These messages can be observed in a short period and even contain a product image, price, or discount links, which helps brands to regain lost sales.

Confirmation of Orders and Tracking of Delivery

‍

Orders can also be automatically forwarded with confirmation of order, shipping and delivery information.

This keeps the customers informed, minimises the number of my order(WISMO) queries, and builds trust.

COD Authentication and Reminder of Payments

In the case of Cash on Delivery orders, there is extensive use of WhatsApp to verify orders to ship.

Brands similarly make reminders of payments on orders paid or pending, and minimise fake or failed deliveries.

Sales Alerts and Promotional Offers

‍

Customers can receive brand notifications with sale alerts, offers, and exclusive discounts.

WhatsApp messages can be read quickly, which is why these campaigns are useful for flash sales and deals that have a time limit.

Customer Support & Queries

Customers are able to request clarifications, follow orders or complain directly on WhatsApp.

Chatbots and quick replies can assist brands in providing rapid and convenient support without making people wait.

With Pragma WhatsApp Business Suite, brands can 3x their customer experience by providing instant support/query resolution and providing a best-in-class experience, 24/7, on the platform of 2Bn+.

It can be used in Customer Retention

With WhatsApp Marketing Messages API, e-commerce brands can better retain customers by developing better, more intimate relationships.

Customers will feel that the brand appreciates them, as they receive birthday and anniversary wishes, as well as special discounts. Such small, considerate messages usually result in repeat purchases as they are not sales-oriented.

Moreover, updating the customers about the loyalty programs, like awarding points, special deals, or membership perks, will keep them interested and willing to make a repeat purchase.

How to Set Up WhatsApp Marketing Messages API?

‍

By following the given steps, you can set up the WhatsApp marketing messages API:

Step 1: Establish a WhatsApp Business Account.

To start with, your business requires a WhatsApp Business account. It is not a normal WhatsApp number, as it is a business-oriented account that is specifically made for the business.

Step 2: Check Your Business with Meta.

Now, you have to verify your business on Meta Business Manager. This will assist WhatsApp in understanding that your brand is true and reliable.

Step 3: Select a WhatsApp API Provider (official).

The API can not be used directly. You must engage an official WhatsApp Business Solution Provider (BSP) to assist in setup, hosting, and support. Here, Pragma can help you!

Step 4: Have Your Message Templates Approved.

You have to submit your message templates to Meta before sending messages to people. This ensures safe messages are spam-free. Normally, it takes around 24-48 hours to get them approved.

Step 5: Become Part of Your E-Commerce Platform.

Integrate the API into your website to send automatic messages such as order confirmations, cart notifications, and messages.

Step 6: Begin Sending and Monitoring Messages.

When everything is live, you will be able to send messages and also trace the delivery, open rates and customer responses, which will help you to enhance your campaigns.

Cloud API vs BSP: What's Better for E-Commerce in India?

Meta offers a cloud API directly. It offers greater control and a little cheaper costs of messaging, though establishment and administration require technical expertise.

Integrations, message templates, hosting and maintenance have to be done by the brands themselves. This alternative suits big e-commerce enterprises that have tech departments.

A BSP takes care of it all, setup, approvals, integrations, automation, dashboards and support. It is not difficult to begin and run without a technical team.

Although it can be slightly more expensive, it will be time-saving and less complex. This alternative will serve small and medium-sized e-commerce brands in India.

BSP is a better choice when you want to set up quickly and reap better results. Cloud API is better in case you demand complete control and possess technological resources.
