Why Privacy Matters in B2B

  • Regulations are tightening globally
  • Prospects expect professional treatment
  • Poor practices damage brand reputation
  • Email providers punish bad actors

Core Privacy Principles

1. Purpose Limitation

Use data only for legitimate business purposes. B2B outreach to relevant prospects is generally acceptable; reselling or misusing data is not.

2. Data Minimization

Collect and retain only data you actually need. Don't hoard data that serves no purpose.

3. Transparency

Be clear about who you are and why you're reaching out. Don't use deceptive practices.

4. Respect Preferences

Honor unsubscribe requests immediately. Remove complainers from all lists.

Practical Best Practices

  • Include clear unsubscribe links in every email
  • Process opt-outs within 24 hours
  • Identify yourself clearly in outreach
  • Store data securely with access controls
  • Don't share data with unauthorized parties

Maintaining Clean Lists

  • Maintain suppression list of opt-outs
  • Scrub against suppression before each campaign
  • Remove hard bounces permanently
  • Re-verify data periodically

Documentation

  • Record data source for all contacts
  • Log opt-out dates and sources
  • Document consent where applicable
  • Keep privacy policy current

Website Identification FAQs

Does Happierleads have a Free trial?

We show you who is visiting your website for free for 30 days. If you’d like to keep using it afterward—and export a CSV or send emails via our built-in Email Automation app or your CRM—the cost is $99/month.

What is Happierleads?

HappierLeads is the only solution that enables you to identify, qualify, and engage with your anonymous B2B website visitors—all within a single tool. No additional licenses or integrations with other outreach automation tools are necessary.

Who typically uses Happierleads?

Happierleads is used by Sales, Growth, and Marketing teams across various industries. If you are a B2B company, we are the solution for you. Sales teams use the platform to turn anonymous traffic into opportunities and increase productivity. While on the other hand, Marketers use the platform to automate lead generation, increase conversions.

How is this different from Clearbit, 6Sense, or DemandBase’s Website Identity Solutions?

Most companies rely on ‘Reverse IP Lookup’ technology to connect IP addresses with company names. At Happierleads, we use a completely different approach—our fully-permissioned, proprietary publisher network—allowing us to identify the exact individuals visiting your website. Discover more about how we identify your site visitors here.

Why is Happierleads ranked number #1 for data quality on G2 and Capterra?

Happierleads offers an advanced feature that automatically filters out bots, ISPs, and other non-qualifying traffic sources to ensure you receive only high-quality leads. Additionally, unlike other tools, Happierleads provides the flexibility for you to manually remove leads as needed.

What about U.S. state privacy laws, like the California CCPA and CPRA?

If you are compliant with these state-level regulations, the use of our product will not change that compliance status. We can now identify exact visitors in 173+ countries including the US, Canada, Australia, and many more. For GDPR-restricted countries (primarily EU member states), we use reverse IP lookup which only provides company information to adhere with GDPR requirements.
