You've got customer feedback scattered across email threads, support tickets, and Slack messages. It's genuinely positive stuff—but when you paste those quotes into a slide deck or social post, they fall flat. Block quotes just don't land the same way.
That's the problem message mockups solve. They take real feedback and present it in a format people immediately recognize: the chat interface they use every day.
Why Marketers Use Mock Screenshots
A quote in a styled box is easy to ignore. The same words in a chat bubble? Audiences process them differently—more quickly, more naturally. It feels like eavesdropping on a real conversation rather than reading marketing copy.
The Familiarity Factor
There's research suggesting people process information faster in familiar formats. A WhatsApp conversation reads quickly because the format is already understood—no learning curve.
Use Case 1: Customer Testimonials
This is the most common application. You have great feedback; you just need a better way to present it. Here's how a SaaS company might showcase customer success using Slack mockups:
Customer Success Story
Showcasing real customer feedback
Why does this work? The format implies authenticity. Readers feel like they're seeing a real exchange, not a marketing-approved quote. (Of course, you should still base mockups on real feedback—fabricated testimonials undermine trust.)
Use Case 2: Social Proof in Ads
Showing that others already use and like your product lowers the barrier for new customers. Mockups let you turn genuine customer reactions into ad creatives, like this X post mockup:

A Note on Authenticity
Always base mockups on real feedback. If you're quoting someone directly, get their permission. Alternatively, you can create composite testimonials that represent common themes—just don't fabricate praise that doesn't exist.
Use Case 3: Product Demonstrations
Sometimes you need to show your product in action, but a real screenshot doesn't quite work—maybe the actual conversation contains sensitive info, or it's just not visually clean. Mockups let you demonstrate the experience without those constraints:

Use Case 4: Tutorial Content
If you're creating educational content about AI tools, prompts, or workflows, mockups let you show exactly what readers should expect to see. Here's a ChatGPT mockup demonstrating a prompt and response:

Use Case 5: Film and Documentary Production
This one's a bit different from marketing, but it comes up often: production teams need realistic phone screens for film and documentary work. iMessage mockups work well as references for VFX or can be displayed directly on prop phones.

Use Case 6: Agency Pitch Decks
Here's a scenario every agency marketer knows: you're pitching a campaign concept, and the client wants to see what it'll look like. You can describe it, or you can show them. Mockups let you visualize the campaign before any production work begins. Here's a LinkedIn post mockup showing how a client announcement might appear:

Best Practices for Marketing Mockups
1. Stay Authentic
This bears repeating: base mockups on real feedback. Fabricated testimonials might look the same, but they feel different—and they can backfire badly if discovered.
2. Match Platform to Audience
Use platforms your audience actually recognizes. A Gen Z audience won't connect with LinkedIn mockups; a B2B buyer might not relate to Instagram DMs. Know your demographic.
3. Keep It Natural
The fastest way to break the illusion is marketing-speak in chat bubbles. Write the way people actually text. Short sentences. Contractions. Maybe an emoji or two.
4. Maintain Consistency
If you're creating multiple mockups for a campaign, keep them visually consistent. Same theme (dark or light), same style. It looks more polished.
Compliance Note
Different industries have different rules about testimonial disclosure. Follow FTC guidelines and your platform's policies. When in doubt, add a "simulated conversation" note.
Does It Actually Work?
Anecdotally, marketers who've switched from text-block testimonials to chat mockups report better engagement—though your results will depend on your audience, content quality, and how authentic the mockups feel. The format alone won't save weak copy.
Getting Started
If you want to try mockups for your marketing:
- Start with one use case: Testimonials are usually the easiest entry point
- Choose platforms your audience knows: Don't guess; match their actual behavior
- Base mockups on real feedback: Authenticity matters more than polish
- Test and iterate: See what resonates before scaling up
