Zalo OA (Zalo Official Account) is a business's official account on Zalo - similar to a "fanpage" but on the Zalo platform - allowing sending mass messages to followers, displaying reputable green ticks, and serving as an official consulting/sales/customer care channel. Unlike personal Zalo, OA supports many employees with management, statistics, and methodical customer care features. Zenify recognizes that businesses that operate Zalo OA effectively increase their conversion rate by 21% (approved).
TL;DR
- Zalo OA = official business account on Zalo.
- Other personal Zalo: many people manage, send mass messages, statistics, green tick.
- Open OA for free, some advanced features charge a fee.
- Operation: post content regularly, reply quickly, auto-reply, advertise.
- Combine OA with channel pooling system to avoid missing information.
What is Zalo OA and why do businesses need it?
Zalo OA is where customers "officially" interact with your business on Zalo. Why is it necessary:
Reputation: Green tick confirms this is an official account — customers trust it more than strange accounts.
Centralized management: many employees handle the same process, have roles, and decentralize authority.
Send proactive messages: send announcements, promotions, and calendar reminders to followers.
Statistics: know number of followers, sent messages, interaction rate.

How to operate Zalo OA effectively
1. Regular content
Post valuable articles 2-3 times/week: products, tips, programs.
Don't just sell — include useful content so your followers won't get bored.
2. Quick reply
Message inquiries answered <15 minutes during office hours.
Consolidate Zalo OA into the common management system if there are many channels (see Multi-channel consolidation).
3. Standard auto-reply
Automatically greet when a customer messages for the first time.
Respond after hours.
Note: do not use auto-reply to replace the real person who replies (see Auto-reply Zalo OA).
4. Exploit your follower list
Send selective notifications: promotions, calendar reminders, after-sale care.
Do not spam — sending too much will cause customers to block OA.
5. Measure and improve
Track number of followers, interaction rate, incoming messages.
If the channel is good, invest more (see Measuring channel effectiveness).
