In this article, I’ll cover what email finder tools do and the best features they offer. Then I’ll review the 9 best finder tools available today.

9 Best Email Finder Tools Overview

The numbers tell you everything you need to know about email’s importance. 91% of businesses use email to communicate with clients. 77% of B2B buyers prefer to be contacted via email. That’s more than double any other channel.

As the most-used communications channel, email remains essential to sales and marketing. But of course, you need to send emails to the right people. How many times have you struggled to find an email address for a great prospect? Or messaged the wrong department in the right organization?

An email finder tool saves you time trawling for addresses manually online. It improves accuracy as you can check you’re getting the right people. The best email finder tools also help make sure you’re sending to genuine addresses.

As with all software, different email finders have different strengths and features. It’s important to match the right tool to your needs. Here’s a quick overview of the 9 best.

What is an Email Finder Tool?

An email finder tool is a kind of search engine for publicly available email addresses. Lots of organisations publish email addresses on their websites. Including addresses for names and contacts. But buried on content-heavy web pages and large websites, these aren’t always easy to find.

An email finder tool does the hard work for you. What you need is a contact name. Plus a company name or a website. The finder tool will then run a search across all relevant URLs. And return any matching email addresses in the search results. 

The Most Important Features of a Good Email Finding Tool

Different email finder tools offer different features. You’ll also find a range of price points. And, of course, differences in interfaces.

It’s important to always choose tools that suit your business. This is most obvious around price. The right tool is email finder is the one that fits your budget and delivers the tools you need.

There are some core features that every good email-finding tool should have. Whichever option you choose, prioritise the following:

• Multiple ways to search for emails: Every email finder works by inputting a contact and company name. But what if you don’t have both? The best finder tools offer multiple options. One example is domain, you enter a web domain and it shows the email addresses linked to it. Some finders will let you narrow your search by job role or search on platforms like LinkedIn.
• Bulk email lookup: Being able to find a single contact’s email address quickly is great. But you often need lots of email addresses at once. Bulk email search allows you to look up 100s of contacts at once. Upload a spreadsheet of contacts to run a bulk search, or narrow down in search window to return all the relevant emails.
• Browser extension: Browser extensions are another great way to simplify email search. With a browser plug-in, you can visit a site, like LinkedIn, and directly run an email search. All the top email finders offer Chrome extensions.
• Export: Speaking of spreadsheets, it’s useful to have export and import options. Once your email finder returns its results, what can you do with them? You should always have the option to export as a CSV file. 
• Integrations & API: Another way to allow easy data import and export is through integrations. All the best email finder tools come with direct plug-ins to third-party platforms. Things like CRM, bulk email services, newsletter platforms, and marketing automation tools, and Zapier. Look for email finders that link to the software you use to use the emails you find straight away. The best email finder tools have an API. With a little programming know-how, you can connect it to any platform.

Don’t forget about email verification

Finding email addresses quickly and easily is a great help, but as professional you often want a bit more. How long have the addresses you found been published on that website? Are they still in use? Does that contact even still work there? 

Email verification is the process of checking email addresses are valid and working. It’s an important step for avoiding bounces. And protecting your sender reputation. Many email finder tools these days offer verification as an additional service. But specialist verification services like Bouncer are more efficient and effective. Find out more about features, pros, cons, and pricing in our guide with the best email verification tools.
