The Conventional Wisdom Is Half-Right

You've heard the narrative: younger customers want chat and messaging, older customers want phone. That's true as a broad trend. But the interesting insights are in the exceptions.

I've compiled data from Salesforce's 2025 State of the Connected Customer report, Zendesk's 2025 CX Trends, Microsoft's 2025 Global State of Customer Service, and survey data from over 15,000 consumers. The picture is more complicated than "young = digital, old = phone."

Channel Preference by Age Group

18-24 (Gen Z)

First choice: in-app chat/messaging (38%). Second choice: social media DMs (24%). Third choice: email (19%). Phone: 8%. Self-service: 11%.

No surprise here. Gen Z grew up texting. They default to asynchronous messaging and will actively avoid phone calls. The interesting finding: 73% of Gen Z respondents said they'd rather solve the problem themselves than talk to anyone (human or bot), which is the highest preference for self-service of any age group.

But when self-service fails, they want chat. Not a chatbot, specifically. They want a human in a chat interface. Gen Z has the lowest trust in chatbots of any demographic (41% trust rate vs. 58% overall), likely because they've grown up dealing with bad ones.

25-34 (Younger Millennials)

First choice: live chat (31%). Second choice: email (27%). Third choice: in-app messaging (20%). Phone: 12%. Self-service: 10%.

This group is the sweet spot for chat-based support. They're comfortable with digital communication but prefer it structured (chat widgets, help centers) rather than informal (social DMs). They're also the most likely to use AI-powered support tools without complaint, with a 62% chatbot trust rate, the highest of any group.

35-44 (Older Millennials)

First choice: email (33%). Second choice: live chat (25%). Third choice: phone (22%). Self-service: 12%. Social: 8%.

The transition zone. Email becomes the top choice because this demographic values having a record of the conversation. They're juggling work and personal responsibilities, so asynchronous communication (respond when it's convenient) beats synchronous (sit in a chat or on a phone).

45-54 (Gen X)

First choice: email (30%). Second choice: phone (28%). Third choice: live chat (22%). Self-service: 14%. Social: 6%.

Nearly tied between email and phone. Gen X is the most pragmatic demographic: they choose whatever channel seems fastest for their specific issue. They have the highest rate of channel-switching (starting on chat, then calling when it's not resolved quickly enough) at 44%.

55+ (Boomers)

First choice: phone (42%). Second choice: email (31%). Third choice: live chat (14%). Self-service: 9%. Social: 4%.

Phone remains dominant but it's declining. In 2023, phone preference for this group was 53%. The 11-point drop in two years reflects growing comfort with digital channels, accelerated by the pandemic-era shift to online services. Still, for anything involving money or account security, this group overwhelmingly prefers voice.

The Twist: Issue Type Matters More Than Age

Here's where it gets interesting. When you control for issue type, the age-based preferences narrow significantly.

Billing disputes and financial issues

Phone preference: 54% across all ages. Even Gen Z respondents chose phone 31% of the time for billing issues, more than double their overall phone preference. When money is involved, people want to hear a human voice. They want real-time confirmation that the issue is resolved. They don't want to wait 24 hours for an email response saying their refund was processed.

Simple status checks ("where's my order?")

Self-service/AI preference: 67% across all ages. Every demographic prefers to check order status without talking to anyone. This is the category where AI classification and automated responses have the highest acceptance rate.

Technical troubleshooting

Chat preference: 41% across all ages. Chat is ideal for tech support because agents can share links, screenshots, and step-by-step instructions. Phone is awkward for technical issues ("OK, now click on the third icon from the left, it looks like a gear").

Complaints and escalations

Phone preference: 48%. Email preference: 29%. When customers are angry, they want to express it in real-time. Email is the second choice because it creates a paper trail. Chat ranks low for complaints because typing out frustration is tedious. Social media is used as a last resort when other channels have failed (only 8% start with social for complaints, but 22% escalate to social after a bad experience elsewhere).

Account changes (cancellation, upgrade, plan switch)

Preference is split: email (32%), phone (28%), chat (24%), self-service (16%). Customers want confirmation and documentation for account changes. The channel matters less than the follow-up: 78% of respondents said they want email confirmation regardless of which channel they used to make the change.

Urgency Changes Everything

For low-urgency issues (feature questions, feedback, how-to), customers are 3x more likely to use self-service or async channels.

For high-urgency issues (can't log in, payment failing, data loss), phone and chat usage spikes regardless of demographic. A 22-year-old whose payment is failing will call. A 65-year-old with a non-urgent question might try the help center first.

The practical implication: your channel strategy should be driven more by issue type and urgency than by customer demographics.

What This Means for Your Channel Strategy

Don't build your support strategy around demographics alone. Build it around the types of issues you handle.

If 60% of your tickets are simple status checks and known-issue questions, invest heavily in self-service and AI classification. The customer preference data supports it across every age group.

If 30% of your tickets involve money (billing, refunds, payments), maintain a phone option. Customers want voice for financial issues regardless of age.

For everything in between, chat is the safest bet. It's acceptable to every demographic and performs well for most issue types.

The most efficient setup in 2026: AI classification and self-service handle the simple stuff (60-70% of volume). Chat handles the middle complexity. Phone handles the high-stakes, emotionally charged issues. Email catches everything async.

That's not a prediction. It's what the data already shows working for the teams that have adopted it.
