April 07, 2025
Objective:#
A large clothing chain wanted to increase sales and improve customer loyalty. Social networks and the website were already working, but the company needed an additional channel to stay in direct contact with customers.
The company chose the method of mass mailing in WhatsApp, where the open rate turned out to be high - about 90%. Therefore, customers will definitely see the information about the offers and can quickly respond to them.

What has been done?#
1. Create personalized content for mailings#
The first step was for the store team to create newsletter copy with customer segmentation in mind. Using personalized messages, they were able to target offers to different groups: new customers - discounts on their first purchase with a special promo code, regular customers - promotions on their favorite brands.
With the help of GREEN-API, the store could be the first to initiate messages in WhatsApp, thanks to which customers would learn about favorable offers, promotions and discounts faster.
2. Mass messaging about new products and promotions#
In addition to personalized messages, the store set up a mass mailing about new products and sales. Every 5-7 days, customers were sent information about new arrivals, seasonal discounts and special offers. This regular brand reminder built interest and created a sense of limited availability.

3. Set up a chatbot to handle inquiries#
For customer support, the company developed a chatbot based on the GREEN-API. The bot in WhatsApp answered basic questions: checked the availability of goods, provided current discounts and suggested the addresses of the nearest stores.
This solution allowed to
● Reduce the workload of managers placing orders;
● Increase the speed of response and quality of service, as the bot responded immediately to requests;
● Keep customers in chat and encourage them to complete the purchase - if they were interested in a particular product, the bot immediately offered to proceed to checkout.
4. Analytics#
GREEN-API provided the ability to track the metrics of each mailing, such as open rate, click-through rate and conversion rate. It turned out that mailings with short-term promotions worked better, and the store started adding such offers regularly.
Results in numbers#
● Sales growth: +15% in the first three months of using WhatsApp newsletters.
● Increased conversions: mailings with short-term promotions increased conversion by 20% compared to standard offers.
● Effectiveness of personalized newsletters: 30% of new customers who were asked to make their first purchase with a discounted promo code did so.
