Facebook Page auto reply with AI: answer every Messenger message

A Facebook Page that sells gets the same questions all day: "price?", "available?", "delivery charge koto?", "COD hobe?". If nobody answers within a few minutes, the customer moves to the next Page in their feed. An auto reply keeps every Messenger message answered, including late at night and during an Eid or 11.11 rush.

What kinds of Facebook Page auto reply are there?

SaleMag gives you the last two. The AI agent handles most questions; keyword auto-reply rules linked to your Page cover fixed replies, and they run before the AI agent.

How does the AI agent answer Messenger messages?

You build a knowledge base with your products, delivery charges, return policy, files, web pages and question-and-answer pairs. The AI agent searches it for each message and writes a short, chat-style answer. It is told to:

• state facts only from your instructions, knowledge base and the customer's own orders
• never invent prices, policies, links, phone numbers or dates
• never offer an out-of-stock product as available
• reply in the customer's language
• ask one short question when a message is unclear

So "eta koto?" gets the price in Banglish, "ডেলিভারি চার্জ কত?" gets your delivery charge in Bangla, and "where is my order?" gets the status of that customer's recent order.

Can the auto reply take orders too?

Yes. Turn on AI order taking and the AI agent moves from answering to selling. It looks up each product in your catalog before it quotes a price, asks for size or colour, builds the cart and sends a secure order-form link. The customer picks Inside or Outside Dhaka (or your own zones), enters name, phone and address, and places a cash-on-delivery order. Your team gets a numbered order and a notification.

What happens when the AI agent should not answer?

You choose whether the AI agent hands over when it is unsure. With handover on, it passes the chat to your team when:

• the answer is not in its knowledge
• the customer asks for a person
• it is a complaint, a bulk order, a custom request or a change to a placed order

Everyone in the workspace is notified, and the chat waits in the shared inbox. While a person handles the chat, the AI agent stays out. With handover off, it says it does not have that information and suggests contacting your team.

What should I put in the knowledge base first?

Write the business instructions in plain words, for example "Always mention that delivery outside Dhaka takes longer" or "Do not offer discounts". The AI agent follows them in every chat.

How do I check the answers before going live?

Use the test chat in the AI agent editor. Type the questions your customers send, for example "price koto?", "XL ache?" or "Sylhet e delivery hobe?", and read the answers. If an answer is weak, add the missing fact to the knowledge base or the instructions and try again. Once you are happy, link the AI agent to your Page. Keep reading real conversations in the inbox for the first week; that is where you find the questions you did not expect.

Does it reply to Facebook post comments?

No. SaleMag answers Messenger messages, not comments on posts or ads. Many Pages ask commenters to "inbox" them; once the customer writes in Messenger, the AI agent answers.

Are there Meta rules I should know?

Meta's Messenger Platform lets a Page reply freely within 24 hours of the customer's last message. Auto replies answer right away, so they fall inside that window. Follow-ups days later are limited by Meta, so reply while the customer is still in the chat.
