1. BetterContact

bettercontacts pricing

BetterContact is the best B2B data vendor, offering a database of 3 billion contact records. It connects to 20+ top-tier sources, such as Apollo and Hunter, and ensures email accuracy of>99.5% through multi-layer verification.

With global coverage, waterfall enrichment features, and native integrations, BetterContact stands out despite the need for separate tools for LinkedIn scraping.

Along with its founders, Roman Hipp and Fredrick Bonnand, the AI-powered waterfall enrichment tool BetterContact was born out of the frustration of insufficient data.

Quick Look:

  • Pay-Per-Result Pricing: Pay only when verified emails are found, optimizing cost.
  • Email Verification: Multi-layer verification with SMTP & Catch-all.
  • Accuracy: Impressive >99.5% accuracy rate.
  • Integration: Hubspot, Make, RB2B, Google Sheet App.

What sets BetterContact apart from other B2B data providers is that it works with all the top data provider tools, accumulating to its impressive database of 3 billion+ contact data, covering the entire world (Europe, the USA, and global markets).

Their enrichment features include native RB2B integration for website visitor identification and a pay-per-result model that ensures you only pay for successful email finds.

One of their mind boggling feature is BetterAI. So how does BetterAI work?

BetterAI: The Algorithm improves phone number database enrichment by identifying strengths in providers based on geography and industry. It analyzes LinkedIn profiles, identifies companies, determines industries, and selects the most relevant data provider. This approach avoids static waterfalls, optimizing data accuracy for specific contexts.

You’d be surprised to know even the top-tier premium enterprise tool doesn’t always provide you with verified contact information, let alone catch-all verification. BetterContact solves that with multi-layered verification.

Multi-Layered Verification: They like to brag about their Multi-Layered verification because barely any data vendor has this feature. So, they do have the brag rights. Multi-layered verification combines typical SMTP and Catch-all verification, providing only verified emails. So, you’ll never need to use tools like Neverbounce or Scrubby.io / Bounceban.

This feature is so rare that only one of the tools in this list has something similar.

The only slight drawback? You’ll need separate scraping tools for LinkedIn leads.

But hey, at least you won’t be stuck with Zoominfo level hefty price tag!

Compliance ensures data privacy and protection. Choose a vendor that meets CCPA and GDPR standards with documented consent protocols. Verify their security measures, such as encryption and breach notification systems, to safeguard your data and maintain trust.

4. Refresh Rate

A frequent refresh rate ensures data accuracy. Vendors offering quarterly updates or real-time refreshes are ideal. Outdated data can lead to failed campaigns, so confirm their update cycles and verify how they maintain database freshness.

Let’s say you extracted contact data in January. However, you ended up using that data in cold email campaigns in March. A few of your leads left the company in February, and now you have invalid emails. To avoid scenarios like that, updating your database more frequently is necessary.

5. Pricing

Pricing varies by vendor. Options range from monthly credits to annual plans, with customizable tiers for specific needs. Discuss volume discounts and ensure pricing aligns with your business goals. Balance cost-effectiveness with data quality and features offered.

Just remember: the cheapest option isn’t always the most cost-effective in the long run.

6. Scalability

Scalability ensures your data vendor can grow with your business. Vendors offering flexible services and adjustable data packages are ideal for expanding teams and larger campaigns.

A scalable provider helps maintain consistent data standards as your needs evolve.

7. Integration

Seamless integration with your CRM and marketing tools saves time and prevents inefficiencies. Look for vendors with API capabilities, real-time synchronization, and pre-built connectors for platforms like Salesforce or HubSpot.

Clear documentation ensures a smooth setup.

8. Support

Strong vendor support ensures quick resolutions to technical issues. Choose providers offering multiple support channels, fast response times, and robust training resources.

Test their responsiveness before committing to the service and check client reviews for quality.
