Reply to a WhatsApp lead from a Facebook or Instagram ad within five minutes, and within one minute if you can. The person who tapped your ad is holding their phone right now, often with two or three businesses' chats open. Lead-response research is consistent on the direction: Harvard Business Review's 2011 study "The Short Life of Online Sales Leads" found that firms contacting leads within an hour were far more likely to qualify them than slower firms, and that most companies were far too slow. On WhatsApp the window is shorter still, because the customer never left the app where your competitors are.
Why WhatsApp leads cool faster than form leads
| Lead form | Email enquiry | WhatsApp from an ad | |
|---|---|---|---|
| Where the person is when they enquire | Leaving Facebook | At a desk | Inside the chat app, phone in hand |
| What they expect | A call "soon" | A reply today | A reply now, like a friend would |
| How easy it is to ask a competitor | Another form | Another email | One tap back to the feed, one more chat |
| What silence feels like | Normal | Normal | Being left on read |
WhatsApp sets an expectation that forms and email never did. Messages show as delivered and read, conversations sit next to friends and family, and most people reply within minutes. A business that answers the next morning is not slow by email standards. It is absent by WhatsApp standards.
What "fast" has to include to count
An instant auto-reply that says "Thanks! We'll get back to you" is fast, and it does nothing for you. Speed only counts if the first reply moves the customer forward. For a typical US small business that means:
- 1An answer to the question they actually asked: price range, availability, whether you serve their zip code.
- 2One question back that helps you help them: "Is this for one room or the whole house?"
- 3A next step they can take now: a booking link, two time options, or "Our estimator will call you at 9 tomorrow, does that work?"
- 4In their language. If they wrote in Spanish, answer in Spanish.
💡 Measure "time to first useful answer", not "time to first message". It is the only response-time number that predicts bookings.
Realistic response times for a small business
| How leads are handled | Typical first useful answer | Weak spot |
|---|---|---|
| Owner answers from their phone | Minutes in quiet hours, hours when busy or after 6 pm | Evenings, weekends, while doing the actual work |
| Receptionist, business hours only | Minutes 9–5 | Every ad tap that comes after hours |
| Auto-reply holding message | Instant "we'll get back to you", real answer hours later | Feels like a brush-off |
| AI assistant that knows the business | Seconds, any hour | Must be one that refuses to guess |
Speed is also the cheap option
Meta charges nothing for messages in the 72 hours after someone taps a click-to-WhatsApp ad. Answering quickly and completely inside that window costs you nothing in Meta fees. Chasing a lead that went quiet a week later means a marketing template at $0.025 each to a US number, and you need their opt-in to send it. Since 1 October 2026 even ordinary replies outside the ad window cost $0.0034 each after 1,000 free a month. The cheapest conversation is the one you finish while it is free.
How to answer every lead in under a minute
Prefill the first message
Set the ad's prefilled text to something specific ("Hi, I saw your ad for AC tune-ups"), so you know which offer they mean without asking.
Give the AI your real facts
Price ranges, service area, hours, booking link. Adyft Reply reads these from your website and asks you about anything missing.
Keep a human in the loop
Anything that needs a site visit, a refund or judgement goes to you, with the chat history attached.
Step back when you are there
When you reply from the WhatsApp Business app on your phone, the assistant stays out of that chat.
Where Adyft fits
Adyft runs the Facebook and Instagram ads that open WhatsApp, and Adyft Reply is built to answer the chats they start, usually within seconds, using what it learned from your site. Today the Free plan gives you that one team inbox for your website chat and Telegram; connecting WhatsApp, Instagram and Messenger, and the paid plans with the AI assistant, open soon, once Meta approves, and we will email you the day they do. Meta tags the first message of an ad conversation with the ad it came from, so you can also see which ads produce real conversations and which only produce taps.
Frequently asked questions
Does Adyft Reply have a free WhatsApp chatbot plan?
Yes. Adyft Reply has a Free plan: just sign up, no card. Today it includes the live team inbox for 3 people, your website chat, Telegram and up to 1,000 contacts; WhatsApp and broadcasts open soon, once Meta approves. Free is the chat system only; the AI assistant comes with the paid plans (from ₹1,499, $29 or £29 a month), which are also opening soon. Details as of 10 October 2026.
How quickly should I respond to a WhatsApp lead?
Within five minutes, and ideally within one. WhatsApp users expect conversational reply times, and a lead who tapped an ad is often comparing several businesses at once.
Does an automatic "thanks, we'll get back to you" message help?
Very little. A holding message is fast but does not answer the question. The response time that predicts bookings is the time to the first useful answer.
Is it free to reply to WhatsApp leads from ads?
Yes, for 72 hours after the customer taps a click-to-WhatsApp ad, under Meta's free entry point rule. Outside that window, US replies cost $0.0034 each after 1,000 free a month since 1 October 2026.
How can a small business reply instantly at night?
With an AI assistant that knows the business's real prices, hours and policies, refuses to invent answers, and hands complex cases to a person. Adyft Reply does this on WhatsApp from $29 a month.
