Mistake 1: Ignoring Data Age

The Problem: Buying data that hasn't been updated in months or years.

The Fix: Ask when data was last updated. Look for monthly refresh schedules.

Mistake 2: Not Testing First

The Problem: Committing to large purchases without validating quality.

The Fix: Request samples. Run small campaigns before scaling.

Mistake 3: Overlooking Total Cost

The Problem: Comparing monthly prices without calculating annual spend.

The Fix: Calculate 2-3 year total cost including seats, credits, and renewals.

Mistake 4: Assuming Bigger is Better

The Problem: Choosing vendors just because they claim the largest database.

The Fix: Focus on relevant contacts for your ICP, not total size.

Mistake 5: Ignoring Export Limits

The Problem: Finding out you can't actually download or use the data freely.

The Fix: Confirm full CSV export rights before purchasing.

Mistake 6: No Verification Strategy

The Problem: Sending to unverified emails and damaging sender reputation.

The Fix: Budget for verification services. Verify before every campaign.

Mistake 7: Skipping Compliance Review

The Problem: Using data in ways that violate regulations.

The Fix: Understand GDPR/CCPA implications. Implement proper opt-out handling.

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.

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.
