Chatbot fallback message examples for AI agents

Chatbot fallback message examples for a small business AI agent: what it says when it does not know, when a question is unclear and when it must not answer, always with a route to a person. 7 scripts, paste-in rules, a filled example, Word and Excel.

1. I don't know: an honest reply plus a route to a person

Most common

The answer is not in your Instructions or Knowledge Base. The agent says so, does not guess, and offers a named person with a reply time.

1.1Topic not in the knowledge base

Unknown topicAnything your sources never mention, for example kids' parties.

Source gapWhat was missing: a price, a rule, a date or the whole topic.

EscalationOffer a person at once; hand over when the visitor says yes.

Contact routeName, or phone or email when offline.

Honest replyThanks for asking. I don't have information about topic, and I don't want to guess. Name from our team can answer this. Shall I pass your question on? I just need your name and email or phone.

1.2The visitor's own order, booking or account

Unknown topicThe status of an order, booking, invoice or account.

Source gapNone: the agent cannot see your order or booking systems.

EscalationAlways hand over, with the order or booking number.

Contact routeName in the chat, or email.

Honest replyI can't see orders or bookings from this chat. If you share your order number and name, I'll pass this to name, who can check it. Expected reply: within time.

1.3Not sure the answer is right

Unknown topicSources that are old, partial or contradict each other.

Source gapBoth versions, for example two prices on two pages.

EscalationGive only the certain part, then offer a person.

Contact routeName in the chat.

Honest replyOur website says the certain part, but I can't confirm the uncertain part. Rather than risk a wrong answer, I can ask name to confirm. Would that help?

If nobody is onlineOur team is offline right now. Leave your name and email or phone and name will reply by time on next working day.

Never

  • Never invent a price, date, rule or service to fill a gap.
  • Never use "I think" or "probably" for facts.
  • Never end with "I don't know" alone: always give a route.

For small sales and support teams

Your agent answers from your sources and hands over the rest.

The agent follows your Instructions and Knowledge Base, filled by hand or with Import from Website. Test fallbacks in Try Bot; handovers wait in Live Support as Awaiting agent.

  • Instructions, Knowledge Base, Import from Website, Try Bot
  • Live Support handover, Chat History, Satisfaction Ratings
  • AI chat free for 3 users; human handover from Launch, $19 a month billed yearly

Free plan: 3 users, AI chat, no credit card.

Filled example

A pottery studio's agent says it doesn't know, and the gap closes the same day

How these chatbot fallback message examples work in a real chat. Moss Hill Pottery, a fictional studio in Portland, Oregon, has an AI agent on its website. On Tuesday 6 October 2026 a parent asked about something nobody had told the agent; Nora Lind, the owner, took over and fixed the gap that afternoon.

Moss Hill Pottery, website chatFictional example
VisitorHi! Do you do pottery parties for kids? 8 children, all 9 years old, on Sunday 18 October. How much would that be?
AI agentThanks for asking! I don't have any information about kids' parties, and I don't want to guess a price or a date. Nora, our owner, can answer this today. Shall I pass your question to her? I just need your name and a phone number or email.
VisitorYes please. Ellen, 503 555 0186.
AI agentThank you, Ellen. I've passed your question to Nora with this chat, so you won't need to repeat anything. She replies here within 2 hours during opening hours, Tuesday to Sunday 10:00 to 18:00. You can also call the studio at 503 555 0140.
Awaiting agent at 10:17, claimed by Nora at 10:24
Nora (owner)Hi Ellen, Nora here. Yes, we host kids' parties from age 7: 8 to 12 children, 90 minutes, $28 per child, and the pieces are ready to collect 2 weeks later. Sunday 18 October at 14:00 is free. Shall I send you the booking link?
VisitorPerfect, yes please!

Why it matters

Why an honest AI chatbot fallback response protects your business

In February 2024, the Civil Resolution Tribunal of British Columbia, Canada, ordered Air Canada to pay a customer 812.02 Canadian dollars in damages, interest and fees. Its website chatbot had said a bereavement fare could be claimed after travel; the airline's policy page said it could not. Air Canada argued it could not be held liable for its chatbot's information. The tribunal called this a remarkable submission: a company is responsible for all the information on its website, whether from a static page or a chatbot1. An honest "I don't know, let me pass you to a person" would have cost nothing.

In the EU, Article 50 of the AI Act requires AI systems that interact directly with people to be designed so that people are informed they are interacting with an AI system, unless it is obvious, at the latest at the first interaction2. It applies from 2 August 20263. Rules differ by country; a one-line disclosure is the easy part.

In a Gartner survey of 5,728 customers, 64% said they would prefer that companies did not use AI in customer service. The top concern: it would get harder to reach a person. Gartner's advice: AI chatbots must tell customers they will connect them to an agent when the AI cannot provide a solution4.

What not to say

What should a chatbot say when it doesn't know? Not these 4 lines

The lines chatbots often fall back on, why they fail with an AI agent, and what to say instead.

"Sorry, I didn't get that."

A dead end from rule-based bots: no answer, no next step.

Say insteadJust to be sure: do you mean option 1 or option 2?

"I think it's around $50."

A confident guess, the real risk with an AI agent: it sounds right and becomes your price.

Say insteadI don't have a price for that, and I don't want to guess. Name can quote it by time.

"Please contact support."

No name, no channel, no time.

Say insteadName can help. Reply here or email email; we answer within time.

"Your booking is confirmed."

Only your booking system or a person can confirm. An invented confirmation is still your promise1.

Say insteadI've noted day at time. Name will confirm by time.

If a weak line comes back after a fix, move the rule higher in the Instructions and retest.

Excel log

The Excel fallback log: every gap, its fix and the retest

Three sheets: Fallback log, Test messages (the 7 from tab 8) and Summary. The app has no automatic fallback report, so each gap gets an owner and a date here. Auto columns fill in by themselves; opens in Excel, LibreOffice and Google Sheets.

ColumnWhat it holds
Date, Visitor question, Topic, Fallback typeWhen, the visitor's words, a short topic, and one of the 7 types from the tabs.
Source gapWhat was missing from the knowledge base. Empty when nothing was.
Agent reply OK, Handed overYes or No for each.
Fix, Owner, Fixed date, Retest date, Retest resultAdd to knowledge base, Always hand over or No change; who, when, and Pass or Fail in Try Bot.
Days to close, Status AutoOpen, Retest, Retest failed, Closed or No fix needed.
Summary AutoFallbacks by type, open gaps, share closed within 7 days, retest pass rate.

The sample is Moss Hill Pottery, 29 September to 7 October 2026: 10 fallbacks, 7 handed to a person, 7 that needed a fix. 5 were closed within 7 days (71%), 2 gaps are still open, and 5 of 6 retests passed (83%). All 7 test messages passed on 6 October.

How to use

How to use these AI agent refusal and uncertainty responses

  1. 1

    Fill in the routes

    Names, reply times, opening hours, phone, email, booking and payment links, and the topics you always hand over.

  2. 2

    Paste and test

    Paste the block from tab 8 and the disclosure line, then run the 7 test messages. All must pass before launch.

  3. 3

    Log every fallback

    15 minutes a day in new chats: one row per fallback with the question, type and source gap.

  4. 4

    Fix within 7 days

    Each row gets an owner and a fix: add the answer to the Knowledge Base, or mark the topic always hand over.

  5. 5

    Retest and close

    Ask again in Try Bot with two wordings. Pass closes the row; Fail means a new fix.

Set it up in CRMsoftware.pro

  1. Open My Bots and choose your bot. On the Basics tab, paste the rules at the end of Instructions (Shared tab) and the disclosure line into First Message.

  3. Click Try Bot and type the 7 test messages until all pass.
  4. On the Behavior tab, turn on Collect User Data and Satisfaction Ratings. On the Advanced tab, use Require privacy acknowledgment and Privacy notice if you show a notice before the chat.
  5. Handovers wait in Live Support as Awaiting agent: Claim, reply, Resolve. On the Connect tab, turn on Send email notifications.
  6. Mark fallback chats with a tag from Settings > Conversation Tags > New tag. The app has no fallback rate or confidence score; the Excel log is your list of gaps.

AI chat, the Knowledge Base, Import from Website and Try Bot are in the Free plan: 3 users, no credit card. Human handover in Live Support comes with Launch, $19 a month billed yearly for 8 users; inbox auto-translation with Growth, $49.

Completion check: a fallback is closed when

  • The missing answer is in the Knowledge Base or Instructions, or the topic is on the always hand over list.
  • A retest in Try Bot passed with two wordings, and its date is in the log.
  • The row has an owner, a fixed date and Pass, so Status shows Closed.
  • No change only when the reply was right and nothing was missing.

FAQ

Chatbot fallback message examples: common questions

What is a chatbot fallback message?

The reply an AI agent gives when it cannot or must not answer: the information is missing, the question is unclear, or the topic needs a person. A good one says so, does not guess, and gives a route: a named person, a reply time, and a phone number, email or booking link.

What should a chatbot say when it doesn't know?

That it does not have the information, that it will not guess, and who can help by when: "I don't have that information, and I don't want to guess. Someone from our team can answer it today. Shall I pass your question on?" Then log the question and add the answer to the knowledge base.

What are good chatbot fallback message examples for an AI agent?

Cover seven cases: not in the sources, an unclear question, an unlisted price or date, sensitive data, advice the agent must not give, a policy exception, and off-topic or abuse. Each needs an honest reply, a handover rule and a contact route; the tabs above give a script for each.

How is an AI agent fallback different from a fallback intent?

A rule-based bot falls back when no intent matches: "Sorry, I didn't get that." An AI agent built on a language model almost always answers, so the risk is a fluent guess. Its fallback is a set of rules in its instructions: when to say it does not know, what never to state, and when to hand over.

Should a chatbot tell users it is an AI?

Yes. In the EU, the AI Act requires AI systems that interact with people to be designed so that people are informed they are interacting with an AI, unless it is obvious, at the latest at the first interaction2. This applies from 2 August 20263. Rules differ by country; a one-line disclosure in the first message is the simple part.

Is a business responsible for wrong chatbot answers?

In British Columbia, Canada, the Civil Resolution Tribunal held Air Canada responsible for its website chatbot's wrong answer about bereavement fares in February 2024, rejecting the argument that it was not liable for the chatbot's information1. Laws differ by country. The safe rule: treat every answer your agent gives as your own statement.

How should an AI agent refuse a request?

Briefly, without blame, and with a next step: what it cannot do, why in a few words, and who can help. "I can't give medical advice. Please ask your pharmacist. For questions about our service, our team can help." A refusal without a route is a dead end.

Does CRMsoftware.pro show a fallback rate or a confidence score?

No. The app does not score answers or count fallbacks. Find them in Chat History and Live Support, mark them with a tag from Settings > Conversation Tags, and track fixes in the Excel log.

How do I set up these fallback rules in CRMsoftware.pro?

Open My Bots, choose the bot, paste the block from tab 8 into Instructions on the Basics tab and click Save Bot. Then test with Try Bot. Handover in Live Support comes with Launch, $19 a month billed yearly.

Write the fallbacks once, then let every gap make the agent better.

Start free with 3 users and AI chat: paste the rules into Instructions, import your website, test in Try Bot. Human handover comes with Launch, $19 a month billed yearly for 8 users.
