## What is a Zalo OA chatbot?

A Zalo OA chatbot is software that automatically answers the messages customers send to a Zalo Official Account, a business's official account on Zalo. Instead of making customers wait for business hours, the bot recommends products, answers questions, and takes orders instantly, 24/7.

Zinochat's Zalo chatbot is **AI-native**: it understands how customers actually write, including abbreviations, missing diacritics, and voice messages, and replies from your shop's data instead of only matching keywords.

## A note on Zalo OA messaging limits

Zalo only lets an Official Account reply to a user within 48 hours of their last message. Zinochat does not send follow-ups that fall outside that window, so schedule your follow-ups within 48 hours. Sending is also subject to Zalo's policies and your OA service package; if Zalo rejects a message, the reason shows right in the conversation.
