Vì sao chatbot Zalo OA quan trọng
Vietnamese customers message Zalo every day - messages asking, buying, and taking care of things are all on Zalo.
No chatbot → manual, slow, out-of-hours responses are missed.
Chatbot Zalo: respond immediately, collect leads into CRM, consult, transfer agents (see CRM Zalo).

Chiến lược chatbot Zalo
Goal | How to use chatbot
24/7 customer care | Answer repeated questions, look up the application
Sales | Consulting, finalizing orders in chat
Collect leads | Ask for contact information → CRM
Care | Schedule reminder, quick survey
Transfer people | Complex problem → agent
Limit messages Zalo needs to know
Zalo OA has a limit on sending messages proactively (not when the customer messages first) according to account type.
Messages reply to customers (within 24 hours from the customer's message) do not count towards advertising limits.
Bulk sending campaigns must comply with limits and avoid spam — being blocked means losing the channel.
Common Zalo chatbot errors
Messenger stereotype scenario: other Zalo habits — language adjustment.
Do not collect leads: After the chatbot answers, it does not ask for information → it cannot be nurtured.
Skip message limit: send ads beyond limit → blocked.
No transferring people: the customer wants to meet the person the bot keeps forever.
Not measured: I don't know how many conversations the bot can handle.
