Customers Stopped Answering. Here's Where They Went.

Every founder I talk to is trying to put AI on outreach. More calls, more emails, more sequences. I think most of that effort is pointed the wrong way. AI makes outbound cheaper, but it also makes people less willing to receive it. The winners will use AI where people are already looking for answers.

Here is how I see the next few years.

1. AI cold calling won't scale, except for reminders and updates

People don't like to talk to AI when they didn't ask for the call. Gartner found that 64% of customers would prefer companies didn't use AI in customer service at all, and 53% would consider switching to a competitor over it.¹ A 2025 survey by Kinsta found 93.4% prefer a human over AI.²

Regulators agree. In February 2024 the US FCC ruled unanimously that AI-generated voices count as "artificial" under the Telephone Consumer Protection Act, which puts AI cold calls under the same rules as robocalls.³ And people had already stopped picking up: only 19% of Americans generally answer calls from unknown numbers.⁴

The exception is calls people expect: an appointment reminder, a delivery update, a payment due date. The value is in the information, not the pitch, so nobody minds who reads it out.

2. The AI receptionist is different, because the caller wants something

Flip the direction and the math changes. When someone calls a clinic, a builder or a salon, they are looking for information. They want the price, the slot, the address. They will talk to an AI receptionist if it answers fast and gets it right.

The need is large. An older study by 411 Locals found small businesses leave 62% of calls unanswered.⁵ Every missed call is a customer who already wanted to buy. That's why I think the biggest voice use case for AI is the receptionist, not the cold caller. Talkdesk found 51% of US small businesses have already put AI into customer service.⁶

3. With AI assistants, people open fewer emails

The inbox now has a layer between the sender and the reader. Gmail shows Gemini summary cards at the top of longer threads without the user asking.⁷ Apple Mail sorts urgent mail into Priority Messages and summarizes the rest.⁸ Personal agents like Meta's Muse, launched this month, promise to take tasks off people's plates and "actually do the work."⁹ Your email will increasingly be read by an agent first.

If an assistant reads your email first, the reader may only see a one-line summary, or nothing. Cold email was already dying. Reply rates fell from 8.5% in 2019 to about 5% in 2025, and the median sender in one large study gets 0.48%.¹⁰ Gmail now requires bulk senders to keep spam complaints under 0.3%.¹¹ With assistants filtering the inbox, I think cold email dies fully.

4. The interesting channel is AI messaging

Messaging is where people already are. WhatsApp alone has more than 3 billion monthly users.¹² Meta says people have more than 1 billion active threads with business accounts every day.¹³

What makes AI messaging different from calls and email:

• It's inbound. The customer starts the chat. Ads can lead to it and websites can lead to it. Meta's click-to-WhatsApp ads grew revenue 60% year over year in Q3 2025,¹³ and Zuckerberg said click-to-message ads had hit a $10 billion annual run rate back in 2023.¹⁴
• It's async. The customer replies when they want. No one has to be on a call at the same time.
• It feels human. A good AI reply in a chat reads like a good human reply. That's why people accept it here when they reject it on a call. (It should still say it's AI. California's bot law and the EU AI Act both require disclosure.^15,16)

Meta already offers businesses an AI agent that chats with customers on WhatsApp.¹⁷ Ads that open a chat, and websites that open a chat, will replace a lot of forms and cold follow-ups.

5. The biggest communication channel is messaging. The world will WeChat-ify

China showed where this goes. WeChat and Weixin have 1.44 billion monthly users combined,¹⁸ and people use it to chat, pay, book and shop without leaving the app. WhatsApp, with business chats, catalogs and payments in India, is moving the same way. I expect the rest of the world to follow: one messaging app as the front door to every business.

6. The biggest paid channel of the future is news articles

When people ask an AI assistant which company to use, the assistant answers from what it reads. Muck Rack studied AI citations and found more than 95% of cited links come from non-paid sources, 85% are earned media, and 27% are journalism.¹⁹ Ads don't show up in that answer. Articles do.

So the channel worth spending on, in PR effort, founder time and story-telling, is getting written about in credible publications. That coverage now reaches buyers twice: once when they read it, and again every time an assistant repeats it.

What this means

1. Stop scaling cold calls and cold email. Keep AI calls for reminders and updates people expect.
2. Answer every inbound call. An AI receptionist catches the customer who is already looking.
3. Route ads and websites into chat. Messaging is async, inbound and where your customers already live.
4. Invest in being written about. News articles are what AI assistants read and repeat.

Outreach isn't going away. It's turning around. The businesses that win will be the ones customers can reach, not the ones that reach the most customers.
