Email Finder Tools: How to Find Email Addresses for Free

People (and especially high-level professionals) are smarter than ever about protecting their contact information online. We can’t blame them, either. Without privacy measures, B2B decision makers would be inundated with emails every day from people they may not even know.

But as a B2B salesperson, you know that even finding information for prospects you’ve met before can be a challenge. That’s why companies need email finder tools.

Email finder tools help companies source email addresses quickly, securely, and often in ways that are integrated with the other systems they use. In this article, we’ll dive deeper into how these tools work and 7 existing tools you may want to try out for your company.

Quick Takeaways

  • Salespeople spend nearly 20% of their time on gathering data.
  • Email finder tools automate the process of sourcing and verifying email addresses for prospects.
  • Trusted tools like Hunter, Sellhack, ContactOut (and more) offer free and premium services so companies can choose the level of service right for them.

What are email finder tools?

It used to be that to find email addresses for prospects, partners, or other important people you needed to reach out to, you’d have to go look for them manually.

In many cases, these manual methods still work. You can search for someone’s name and company on Google. You can connect with them on LinkedIn and find their email address on their profile. You can scour online web directories.

And guess what? You’ll often successfully find the email you were looking for.

But there are several drawbacks to these methods, especially for companies that want to maintain trustworthy processes for finding and managing people’s contact information.

Email addresses found through public search can be unreliable and are often unverified. You can’t be sure the sites you’re finding email addresses on comply with data privacy laws. Most of all (and most impractically for salespeople), these manual methods take a lot of time.

It’s no secret that salespeople wish they could spend more time actually selling. But did you know they spend nearly 20% of their time on researching and gathering prospect data alone?

That does not have to be the norm for your company.

Email finder tools can transform your ability to search for email addresses at the speed and scale required by growing businesses. By definition, they’re databases of email addresses curated from a variety of reliable sources online. Addresses found through email finder tools have been found using compliant collection methods and undergo a verification process.

Using them is simple: you enter a single email address or upload a list of contacts to find addresses in bulk. The tool delivers you an email address(es) in return.

Even better? Many of these email finder tools are (at least partly) free of charge. Let’s check out 7 of the best ones to consider.
