Brand Voice Guide: How to Find and Maintain Your Product's Unique Personality

Why does some product communications feel like a breath of fresh air while others sound like they were written by a committee?

The difference is brand voice—the unique personality that comes through in every word you write.

For Product Marketing Managers, brand voice is the secret weapon that turns dry release notes into engaging content people actually want to read. This guide will help you discover, define, and deploy a consistent brand voice across all your product communications.

What is Brand Voice?

Brand voice is the distinct personality your brand expresses through words and tone. It's not just what you say—it's how you say it.

Brand Voice Includes:

Word choice (vocabulary and phrases)
Sentence structure (short and punchy vs. long and flowing)
Tone (serious, playful, professional, casual)
Perspective (we-focused, you-focused, or neutral)
Personality traits (bold, humble, confident, approachable)

Brand Voice is NOT:

Visual design (that's brand identity)
Logo and colors (that's brand visual system)
Products you sell (that's your offering)
Your mission statement (that's your purpose)

Why Brand Voice Matters for Release Communications

Great brand voice in release announcements:

Builds Recognition: Readers know it's you without seeing your logo
Creates Trust: Consistency feels authentic and reliable
Increases Engagement: Personality makes content more engaging
Differentiates: Stand out from competitors who sound generic
Humanizes: Makes your product feel like it's made by real people

Example: Look at how Slack and GitLab communicate about releases. Both have strong, distinct voices. You could identify their announcements without logos.

The Four Brand Voice Archetypes

Based on analysis of thousands of SaaS companies, most brand voices fall into four archetypes:

1. Professional

Characteristics: Formal, authoritative, precise, respectful Best For: Enterprise software, B2B tools, regulated industries Example Announcement:

"We are pleased to announce the release of Version 2.5.0, which introduces enhanced security protocols designed to protect your data with industry-leading encryption standards. This update represents our continued commitment to maintaining the highest levels of security for our enterprise customers."

Key Words: pleased, announce, enhanced, designed, commitment

2. Technical

Characteristics: Detailed, precise, straightforward, developer-focused Best For: Developer tools, APIs, infrastructure products Example Announcement:

"v2.5.0 introduces several API changes. The authentication endpoint now supports OAuth 2.0 with PKCE. We've also added a new GraphQL endpoint for batch queries. See the migration guide for breaking changes."

Key Words: introduces, supports, added, migration, breaking changes

3. Casual

Characteristics: Conversational, friendly, approachable, simple Best For: Consumer apps, SMB tools, modern startups Example Announcement:

"Big news! We've made some awesome updates that we think you're going to love. Dark mode is finally here (we know you've been asking), and we've made the whole app faster than ever. Check it out and let us know what you think!"

Key Words: big news, awesome, love, finally, faster

4. Playful

Characteristics: Witty, fun, surprising, emoji-friendly Best For: Creative tools, modern consumer apps, brands targeting millennials/Gen Z Example Announcement:

"🎉 Hold onto your hats, folks. v2.5.0 has ARRIVED and it's bringing the party. Dark mode? Check. Lightning speed? Double check. We've been working hard and we're SO excited for you to see what we've built. Let's gooooo! 🚀"

Key Words: party, check, SO excited, let's go Discover Your Brand Voice Find Your Brand Voice Archetype

How to Discover Your Brand Voice

Step 1: Answer These 5 Questions

If your brand was a person, how would you describe them?

- Age, profession, personality type?

How do you want customers to feel after reading your communications?

- Informed? Excited? Reassured? Inspired?

What's your relationship with customers?

- Teacher? Partner? Friend? Advisor?

How formal should you be?

- Suit and tie? Business casual? Jeans and t-shirt?

What personality traits represent your brand?

- Pick 3-5 adjectives (e.g., bold, humble, confident, witty, straightforward)

Step 2: Analyze Your Existing Communications

Review your last 10 release announcements. Look for:

Words you use frequently: What's your vocabulary?
Sentence patterns: Long and complex or short and simple?
Perspective: How often do you say "we" vs. "you"?
Emotional tone: Serious, excited, helpful, urgent?

Step 3: Check Competitors (and Be Different)

Analyze how 3-5 competitors communicate. Then deliberately choose a different approach.

If competitors are formal and serious, consider being more approachable. If they're playful and quirky, consider being more straightforward. Differentiation helps you stand out.

Step 4: Test with Real Customers

Share sample communications written in different voices with customers. Ask:

Which version feels most authentic to us?
Which version do you prefer reading?
Which version makes you trust us more?

Documenting Your Brand Voice

Once you've identified your voice, document it so everyone can use it consistently.

Writing in Your Brand Voice

Technique #1: The Rewrite Method

Write a first draft without worrying about voice. Then rewrite paragraph by paragraph in your brand voice.

Before (Generic):

We have added a new feature that allows users to export their data in CSV format.

After (Casual Voice):

Export your data anywhere with one-click CSV downloads. Move your data between tools seamlessly.

After (Professional Voice):

We are pleased to introduce CSV export functionality, enabling you to transfer your data between systems with ease.

Technique #2: The Voice Check List

Before publishing any communication, verify:

[ ] Does this sound like us?
[ ] Would readers recognize this as our brand without our logo?
[ ] Are we using our characteristic words and phrases?
[ ] Is the emotional tone consistent with our guidelines?

Technique #3: The Comparison Method

Keep examples of your best communications handy. When writing new content, compare against those examples to ensure consistency.

Maintaining Brand Voice at Scale

As your team grows, maintaining consistent voice becomes challenging. Here's how to scale:

1. Create a Voice Library

Build a collection of approved copy templates for common scenarios:

Feature announcements
Bug fix communications
Maintenance notices
Welcome emails
Error messages

2. Train Your Team

Don't assume everyone "gets it." Conduct training sessions:

Review the voice guidelines together
Analyze examples of good vs. bad voice
Practice rewriting generic copy in your voice
Create a shared document where anyone can ask "does this sound like us?"

3. Use Tools

Brand Voice Questionnaire

Tools like Updateberry's Brand Voice Questionnaire help align your team on a shared understanding of your brand personality.

4. Establish Review Process

For high-stakes communications (major releases, crisis communications), establish a review process:

Draft by one person
Voice check by designated guardian
Final approval by PMM lead

Real-World Brand Voice Examples

Stripe (Technical + Trustworthy)

"We've added support for [Feature]. This means you can now [benefit]. Learn more in our documentation."

Characteristics: Clear, direct, assumes technical audience, focus on utility

Slack (Friendly + Helpful)

"New thing alert! We've made it easier to [task]. Here's how it works..."

Characteristics: Conversational, enthusiastic, clear explanations, assumes non-technical audience

Notion (Aspirational + Inspiring)

"Introducing [Feature]. Build [outcome] faster than ever."

Characteristics: Focus on what users can create, inspiring, confident but not arrogant

GitHub (Pragmatic + Developer-Focused)

"[Feature] is now available. See the [changelog/docs] for details."

Characteristics: Minimal, factual, respects developer time, assumes readers can fill in details

Evolving Your Brand Voice

Your brand voice isn't static. As your company grows and changes, your voice should evolve.

When to Reconsider Your Voice

Major product pivot: Your old voice may not fit new positioning
New audience: Expanding from developers to business users?
Market maturation: Early startup voice may not scale
Acquisition: Maintaining distinct voices vs. consolidating

How to Evolve Gracefully

Make gradual changes: Sudden shifts confuse loyal customers
Explain the evolution: "As we've grown, we're..."
Test before committing: A/B test new voice elements
Maintain core elements: Keep some recognizably "you" elements

Common Brand Voice Mistakes

Mistake #1: Inconsistency

Problem: Sounding formal one week, casual the next Solution: Document guidelines and use templates

Mistake #2: Voice Without Substance

Problem: Great personality but no useful information Solution: Voice is the delivery mechanism, not the content. Ensure value first.

Mistake #3: Copying Competitors

Problem: Sounding exactly like [major competitor] Solution: Conscious differentiation. Choose a different approach.

Mistake #4: Voice-Product Mismatch

Problem: Playful voice for serious enterprise security product Solution: Match voice to audience expectations and product context

Mistake #5: Over-Correcting

Problem: Swinging too far in the opposite direction Solution: Evolution, not revolution. Small adjustments over time.

Quick Reference: Voice by Product Type

Product Type	Recommended Voice	Example Phrases
Enterprise Software	Professional, authoritative	"pleased to announce," "enhanced security," "enterprise-grade"
Developer Tools	Technical, straightforward	"API change," "deprecation notice," "see docs"
SMB SaaS	Approachable, helpful	"introducing," "now available," "learn more"
Consumer Apps	Casual, friendly	"new feature," "you asked," "we listened"
Creative Tools	Inspiring, empowering	"create," "build," "make it yours"

Conclusion

Your brand voice is a powerful differentiator. In a world of generic product communications, a distinctive, consistent voice helps you stand out, build trust, and create lasting relationships with customers.

Invest the time to discover, document, and deploy your brand voice. It's one of the highest-leverage activities for Product Marketing Managers.
