The Rise of Millennial & Generation Z Buyers: What Brands Must Know

The marketplace is changing — fast. Two demographic cohorts, in particular, are remaking how brands sell: Millennials (born roughly 1981–1996) and Gen Z (born roughly 1997–2012). Their values, digital fluencies, and expectations are shifting what successful customer journeys look like.

What This Means: Instant Gratification & Anti-Sales Vibes

Here are some key stats and insights:

  • Gen Z spending is growing twice as fast as previous generations’ did at the same age, and by 2029 Gen Z is expected to eclipse Baby Boomers’ global spending. 
  • Gen Z already represents somewhere between $360 billion to $450 billion in spending power (in the U.S.), and that number is expected to keep rising.
  • Among both Millennials and Gen Z, convenience and speed are no longer bonuses — they are basic expectations. Next-day delivery, fast checkouts, free returns are table stakes. 
  • These buyers are more likely to abandon a purchase if the process is clunky. One survey found that among Gen Z, ~46% want quick and easy checkout, and fast shipping is almost equally important. 
  • When it comes to communication preferences:
    • 75% of Gen Z say they prefer texting or message‐based communication over phone calls. 
    • 80% of Millennials expect near-immediate responses from brands. 
    • SMS opens are extremely high (≈ 98%), and many messages are read within minutes. 

What This Means: Instant Gratification & Anti-Sales Vibes

Millennials and Gen Z grew up in an era of instant access — fast internet, on-demand streaming, one-click shopping, same-day or next-day delivery. They expect:

  • Speed and frictionless experiences: If a site is slow, a checkout takes too long, or customer support is hard to reach, they’ll bounce.
  • Autonomy and control: They don’t want to be “sold to” via pushy sales calls or long email chains. They want seamless digital paths and less pressure.
  • Authentic, useful communication: Spammy outreach, impersonal mass emails or cold calls are increasingly ineffective, even irritating.

That “anti-sales” posture isn’t “anti-commerce” — it’s about rejecting what feels outdated or overly aggressive in favor of relevance, convenience, and respect.

Why Conversational SMS Engagement Is a Game-Changer

Given these expectations, SMS and conversational messaging shine for several reasons:

  1. Immediate visibility & fast responses
    SMS enjoys open rates around 98%, with a very high percentage of messages read within minutes.
  1. Low barrier, high comfort
    Texting (or chat‐type messaging) feels natural, low effort, informal. For Gen Z and many Millennials, it’s preferable to phone calls or even long email threads. 
  1. Conversion & revenue impact
    Brands using SMS report strong ROI — sometimes 10-20% (or more) of revenue coming directly from SMS strategies. Abandoned-checkout SMS messages often drive very high conversion rates. 
  1. Brand relationship & trust building
    Conversational SMS allows for personalization, two-way dialogue, quick feedback, and feeling heard. These are crucial to Millennial/Gen Z loyalty.

Using Tools that Fit This New Buyer Mindset

To meet these customers where they expect to be met, brands need tools that are:

  • Fast and automated, yet feel human
  • Conversational, with two-way capabilities
  • Integrated with marketing, fulfillment, and support workflows so nothing slows down

One example of a tool built with these priorities in mind is MockInByrd.ai. While every brand must evaluate tools themselves, here are a few ways MockInByrd.ai (or tools like it) can align with Millennial/Gen Z expectations:

  • Enabling SMS / messaging campaigns that feel personalized and responsive
  • Letting brands generate leads via chat-type interactions instead of forcing a phone call or in-person appointment
  • Maintaining engagement through conversational follow-ups, answering questions quickly, reducing friction
  • Building the brand by being seen as tech-savvy, customer-centric, and responsive rather than pushy or slow

Conclusion

The rise of Millennials and Gen Z buyers isn’t just about demographic changes — it’s about new norms in how people want to interact with brands. Instant gratification, autonomy, and anti-sales sentiment aren’t disadvantages — they’re guideposts for what works today.

Brands that adapt — especially by leaning into conversational SMS engagement and tools like MockInByrd.ai — will be the ones that attract, convert, and keep these customers.
