In Southeast Asia, especially Vietnam, Zalo has become a highly popular instant messaging tool with a vast user base. For cross-border sellers, foreign trade practitioners, and local businesses, Zalo is not only a communication tool but also an important channel for marketing and customer acquisition. However, under strict official control, how to safely and efficiently use Zalo's bulk messaging feature to reach customer groups is a key concern for many marketers. This guide will provide a detailed analysis of the benefits, methods, and practical steps of Zalo bulk messaging.
Benefits of Zalo Bulk Messaging
Zalo bulk messaging offers multiple advantages, making it an attractive choice for businesses to engage with their target audiences:
1. Save Time on Customer Outreach
Using Zalo bulk messaging significantly reduces the time needed to send individual messages to customers. Businesses can quickly reach a large audience with personalized information, freeing up valuable resources.
2. High Reach Rate and Engagement Rate
Zalo has over 80 million active users in Vietnam, with high coverage and strong user stickiness. Bulk messages can quickly reach target users, and the open rate is much higher than traditional email marketing, increasing the likelihood of customer interaction.
3. Reduce Missed and Cancelled Appointments
Automated bulk messaging can drastically reduce no-shows and cancellations by sending timely reminders and confirmations directly to customers' devices, thereby improving operational efficiency and profitability.
Methods of Zalo Bulk Messaging
Method 1: Manual Bulk Messaging via Personal Account
This is the most basic method, suitable for cases with a small number of friends (e.g., a few hundred).
Procedure:
① In the Zalo app, go to "Contacts"
② Click the "Broadcast" icon in the top right corner
③ Manually select the friends to send to
④ Edit the content and send.
Disadvantages:
- Number limit: Can only select up to 100 friends at a time.
- Low efficiency: Frequent operation is time-consuming and labor-intensive.
Method 2: Bulk Messaging via Zalo OA Backend
This is the official marketing channel provided by Zalo for businesses, an efficient choice for large-scale, professional bulk messaging.
Procedure:
① Log in to the Zalo OA management backend
② Click on "Broadcast/群发消息" in the left menu
③ Edit the message content (supports text, images, links, buttons, etc.)
④ Select the target audience: all followers or users grouped by specific tags.
⑤ Set the sending time (send immediately or schedule).
⑥ Click "Send" to complete.
However, this method has certain restrictions, as follows:
- Limited frequency (authenticated OA: max 4 messages per month; unauthenticated: even fewer).
- Limited audience (can only send to users who have followed the OA).
- Strict content control (all bulk content must pass Zalo's automatic review before sending; marketing information may easily fail review).
- OA backend automation capabilities are weak, relying heavily on manual operation.
