Marketers today are inundated with data—and that data can feel like a double-edged sword, offering opportunities but also requiring care to safeguard it effectively. After all, customer data can fuel engagement and growth, but it brings with it significant risks if you fail to manage it carefully and ethically.

In this guide to data protection and privacy, we’ll go over essential strategies for respecting privacy and protecting data, while also delivering an impactful, compliant, data-based marketing strategy.

What is data protection and privacy?

While privacy is the term generally used to describe a person’s right to control their private information, data protection is often used to describe the set of measures and legal requirements that need to be implemented by companies to protect individuals' personal data.

In practice, data protection and privacy principles require companies to focus on respecting consumer choices regarding the collection, use, and sharing of their personal data and implementing safeguards to protect this information from unauthorized access, breaches, or misuse. When you put data protection and privacy at the core of your engagement strategy, it can build consumer confidence, bolster your brand reputation, and make it easier for your organization to comply effectively with potential new rules and regulations.

Why are data protection and privacy important?

Marketers and brands need to understand and comply with relevant data regulations. And not just to avoid substantial fines for non-compliance.

Rigorous data privacy and protection practices help you stay on the right side of both customer sentiment and legal requirements. Plus, by building a thoughtful strategy for data usage, you can more effectively collect and leverage customer data to deliver value and unlock higher engagement. Here’s what you need to know.

Legal compliance and risk reduction

As consumers have grown more protective of their privacy, a host of laws and regulations aimed at supporting data privacy have been introduced, from the General Data Protection Regulation (GDPR) in the European Union to the Virginia Consumer Data Protection Act (VCDPA) and California Consumer Privacy Act (CCPA) in the United States.

These laws require businesses to adhere to specific guidelines for collecting, processing, and storing personal data. Non-compliance can result in significant financial penalties as well as reputational damage.

And, of course, implementing robust data protection procedures protects brands and consumers alike against the risk of data breaches, which can have dire consequences. Safeguarding personal data against cyber criminals and malicious access mitigates this risk.

Building trust with customers

Customers are increasingly cautious about sharing their data, and it’s easy to see why. From the minor irritation of being added to mailing lists involuntarily to major concerns over data breaches and identity theft, consumers rightly want to protect their details.

McKinsey research shows 87% of consumers won’t do business with a company if they’re concerned about its security practices. And 71% said they’d stop doing business with a company that gave away their data without permission. The same research found consumers are more likely to trust companies that don’t ask for information that isn’t relevant to the product and that don’t ask for too much personal information.

Enforcing your robust privacy and data protection measures is essential if you want to build trust with customers and encourage them to volunteer pertinent data.

Delivering value and personalization

Personalization and privacy can seem like a chicken-and-egg scenario—which comes first? Customers want value in exchange for their data, but marketers need data to deliver that value.

In 2023, Deloitte research found only half of consumers believe the value they get from online services outweighs their privacy concerns. That’s a nine percentage point drop from 2021.

Responsible data privacy practices help businesses gain trust and collect the data they need to deliver the personalized customer engagement that customers crave.

First-party data collection helps you build a more comprehensive picture of each customer, allowing you to deliver more relevant, personalized messaging. And it’s not just about collecting contact details to arrange delivery.

  • Preference centers let users select their preferred communication channels and opt in
  • Newsletter sign-up forms can capture information about customer interests
  • Pop-up surveys can uncover customer pain points or preferences

Combined with transactional and behavioral data, you can send relevant, contextualized messages that you know your customers actually want (because they told you so).

8 ways to embrace data protection and privacy in your customer engagement strategy

Trust takes years to build but only seconds to lose. Why risk it?

The core ideas are simple. Don’t collect data that doesn’t support your business goals—and stop retaining it when it no longer serves a legitimate purpose. Protect the data well by anonymizing and encrypting it. And restrict access to approved personnel only.

Here are eight ways to make ethical data practice your marketing North Star.

1. Embed privacy into every process

Embrace privacy consciousness during the full marketing lifecycle, from initial campaign concepts to the implementation of data processes. For example, consider whether a campaign idea would involve collecting especially sensitive data, whether that is justified, and what additional privacy measures need to be put in place to protect it.

2. Collect minimum viable data

Make it your policy that you only collect data that is relevant and necessary for your specific marketing purposes; this is known as minimum viable data. Avoid collecting excess or irrelevant data and dispose of any data when it is no longer needed. Ask questions like:

  • What type of data do we need to collect and why?
  • How will we collect, maintain, secure, and dispose of that data?
  • What systems will it be held in and how are they secured?
  • Who will have access to the data and how can it be used?
  • Do we have legitimate grounds to collect and retain that data?

3. Be crystal clear and obtain consent

There’s nothing worse than underhanded tricks for gaining consent to gather user data—like baffling opt-in small print or pre-filled opt-in options. Be transparent about the type of data you collect and why. Give people the option to explicitly opt-in or opt-out of data processing activities. And make it easy for people to update their preferences if they change their minds.

4. Highlight credentials and benefits

88% of people say their willingness to share personal data depends on the trust they have in the company in question. To encourage people to trust you with their data, highlight both your security credentials and the benefits they’ll get. Showcase trust and security certificates on your website and app, especially at the point of data collection, such as checkout or newsletter sign-up. And explain what they’ll get in exchange, such as discounts or curated recommendations.

5. Make data processes compliant

Ensure your data collection, storage, access, and disposal processes are compliant with the regulations in your jurisdiction. Remember, if you’re processing customer data from other countries, their home country’s regulations apply. For example, if you are a US company processing French customer data, you still must comply with the EU’s GDPR.

6. Secure data appropriately

Use appropriate tools and technology to secure and protect the data you collect. Ensure that sensitive information is encrypted at rest and in transit, implement anonymization techniques to protect individual identities, and enforce strict access controls.

7. Pick your partners wisely

The technologies you use in your customer engagement efforts can have a significant positive (or negative) impact on the privacy and security of the customer data you hold. Thankfully, Braze blends advanced security and workflow capabilities with practical, user-friendly tools. This empowers marketers at every level to confidently craft campaigns that meet security, privacy, and compliance needs, ensuring the integrity of their work and fostering trust with every message on any channel.

Your team has to rise to the challenge of meeting the growing expectations of today’s consumers, and your tools should help you do this easily and quickly. As you grow, your partner should help you move faster and eliminate rework, make it simpler to connect with new communities, and proactively resolve potential issues before you go live.

8. Dispose of data when you’re done with it

People’s preferences may change and data loses its currency over time, so it’s important to dispose of data responsibly and within a reasonable timeframe.

  • Establish data retention policies to determine how long you’ll retain personal data
  • Contact users before deleting their data to ask if they’d like to update it or have it retained
  • Dispose of data securely when it is no longer needed for its stated, legitimate purpose

These eight tips can help you build a more trusting relationship with customers, secure their data, and use it to deliver a better experience—which in turn builds engagement, loyalty, and value.

2. Create unique IDs

Braze amalgamates customer data from all of their disparate sources and devices—like your website and app, their laptop and mobile—so you get a single, holistic view of each customer, wherever they engage with your brand.

Each profile has a unique ID based on your chosen format. To make sure your chosen ID format protects privacy and is less vulnerable to malicious actors:

  • Don’t use an easily guessable identifier
  • Don’t use email addresses or public user names

3. Secure your SDK

SDKs are the behind-the-scenes kit that makes data amalgamation and segmentation possible. With SDKs playing such a key role in customer engagement efforts, it’s essential they’re secure.

The Braze platform’s SDK authentication feature is like multi-factor authentication for your SDK, requiring proof that users are who they say they are. This stops malicious access using a stolen or hacked ID.

Stay up to date with the latest SDK versions too. These will include the latest security features in response to emerging risks, plus bug fixes and performance improvements.

4. Implement roles for access control

Braze features like Roles and Just-in-time Provisioning—which help streamline team access controls and permissions—can enhance marketers’ security while using improved security features to proactively manage and communicate potential issues. An example of this would be using structured user access controls to reduce unauthorized data access incidents. Such proactive measures not only ensure compliance but also fortify customer trust in your brand’s commitment to security.

5. Use a tag manager

Braze integrates with all the top tag managers including Google Tag Manager, Segment, mParticle, and more. One of the many benefits is that these integrate with the privacy and consent management tools mentioned above.

That makes it easy to deploy certain types of data collection only when a user consents, proving to customers that you recognize and respect their privacy preferences.
