Can we publish this testimonial without more proof?

Hold the testimonial until its source, wording and any objective claim can be supported. A genuine customer quote still needs documentary proof, clear attribution and a check of the overall impression it creates. Credible communications protect brand trust without making the campaign less distinctive.

A testimonial needs proof of both the person and the promise

A testimonial should stay unpublished when the team cannot show that the customer is genuine and that the quote is accurate. Keep documentary evidence that the testimonial or endorsement came from the named person or organisation, along with contact details that allow the source to be verified.

Check the wording for more than a warm opinion. A line such as "easy to work with" is brand storytelling. A line such as "cut implementation time in half" makes an objectively testable performance claim, so the campaign needs a reasonable basis for that result before launch. Preserve the original quote, confirm who said it and identify any claim that could be read as a promise. Claims need to be watertight and backed by evidence, especially where trust, health, safety or business outcomes are at stake.

The audience's overall impression matters more than a technically true line

A testimonial can mislead when its headline claim sounds broader, more typical or more certain than the proof behind it. Review the copy, imagery, placement and any qualifications together, because audiences experience the campaign as one message rather than as separate legal and creative parts.

Put material limits close to the claim and write them in plain English. A small footnote will not bring clarity when a bold statement creates a different impression. The same discipline matters for environmental claims, where a positive story needs to reflect the real work behind it rather than hand-wave at a bigger promise. Honest context does not weaken a campaign. It gives the creative idea enough substance to stand up to scrutiny and helps protect brand integrity when a customer, competitor or journalist looks closer.

We build campaigns on proof, not post-rationalisation

We believe distinctive creative work and evidence-backed claims belong together. A testimonial should feel human, but it should also survive a straight-talking check of who said it, what it promises and how an audience is likely to read it. That is how brand authenticity becomes practical, rather than a nice idea.

We start with the deeper context, audience expectations and the substance behind a story before shaping the creative expression. For Dematic's first sustainability report, we used its rigorous internal ESG reporting as the base and worked with business leaders to tell the stories behind the numbers honestly and humanely. For high-stakes communications, we favour clear fact checking and the right approvals before the work goes live.

FAQs

How do we know whether to put this testimonial out now or seek further proof first?

A testimonial campaign needs a record showing that the endorser is genuine, the quote is accurate and any objective result can be substantiated. Keep the original source material, the endorser's contact details, evidence for performance or outcome claims, and the final approved wording. Review qualifications, imagery and placement together so the finished campaign communicates with clarity rather than creating a misleading overall impression.

Can a real customer testimonial still be misleading?

Yes, a real customer testimonial can still be misleading when audiences are likely to take away a broader claim than the evidence supports. A genuine individual result may not prove that every customer will get the same outcome. Clear context and careful wording help the campaign reflect the story honestly.

Can creative storytelling replace claims substantiation?

No, creative storytelling cannot replace proof for an objectively testable claim. Bold, human storytelling can make a campaign more engaging, but false claims, concealed limitations and truth-stretching promises erode trust. When proof is thin, focus the message on what can be explained clearly and honestly.

Should a campaign disclose limitations or negative information?

A campaign should disclose limitations that are necessary to stop the audience drawing a misleading conclusion. The goal is not to bury people in detail or undermine the proposition. The goal is to give material context in clear language, particularly where a claim could otherwise imply a wider benefit or certainty.

How do I approve a customer testimonial for publication?

Use a short evidence check before creative approval so the testimonial remains human, credible and clear.

  1. Capture the original source

    Save the original testimonial, identify the person or organisation behind it and retain their contact details. Confirm that the proposed wording accurately reflects what they said rather than a polished version that changes the meaning.

  2. Test every implied promise

    Mark any phrase that suggests a measurable result, comparative advantage, environmental benefit, health outcome or typical customer experience. Match each claim to documentary proof, or remove or narrow the wording until the claim reflects what can be supported.

  3. Review the finished message

    Assess the headline, testimonial, imagery, qualifications and call to action as one audience experience. Add clear material context, then record the evidence owner and final approval before publication.
