Hunter.io Review

Hunter.io is a tool to help you find professional (valid) email addresses quickly and easily.

The typical use cases would be if you’re involved with sales lead generation or outreach based link building. 

In this review I’m going to take a look at the features available with Hunter, the data it produces and how easy it is to use. 

Hands on with Hunter 

Hunter has a number of different methods to find valid email addresses. These include: 

• Domain search: It lists publicly available email addresses with confidence scores, department filters, and detailed sources. 
• Email finder: It puts all available data together, email formats, email addresses found on the web, verifications and other signals, to find the right contact. 
• Author finder: Paste in a URL and find the email address of the article author. 
• Bulk uploads: Upload a list of names with domains or companies and get your file enriched with verified email addresses. 
• Browser extension: Hunter’s browser add-on lets you immediately find the email addresses behind the website you’re browsing. 
• Email verifier: Validate that an email address exists and can receive emails. 

The results are on the whole pretty good. 

For very large businesses, with hundreds or even thousands of results, it can be difficult to filter down to the contact that’s most appropriate for you, but not impossible. 

I like that they don’t claim every result is accurate or worth using. Next to each result, Hunter includes a verified address badge (if applicable) as well as a confidence score so you’re not hitting dead or questionable inboxes. Hunter also lists (when known): 

• The source(s) of the email address 
• Department 
• Job title 
• Phone number 
• Social profiles 

Handily, you can save each result as a ‘’lead’ within Hunter’s control panel and/or export the results as a CSV to use elsewhere. 

I found the browser extension the easiest way of conducting outreach research across multiple websites. Here’s the result for Hunter’s website… 

Clicking on the email address saves it to my clipboard or I can add it as a lead within Hunter by clicking the ‘+’ icon. 

Hunter also comes with a ‘Campaigns’ tool, to compose campaigns and schedule follow-ups with your leads through your Google or Microsoft account. 

I haven’t used this feature so can’t judge its worth, but it’s there if you need it. 

On the whole, I’m a fan of Hunter. I’ve used it numerous times to help build outreach lists for link building campaigns and it really cuts down the amount of time it takes to find contacts. It often beings back emails you’d probably never find within a worthwhile time frame. 

Should I use Hunter? 

Hunter is an effective tool for developing outreach campaigns across multiple verticals. The learning curve is next to zero, and you can be up and running in minutes. 

Combine it with a tool like mailshake.com to scale your link building through intelligent automation. 

When it comes to accuracy, the bigger the business/site you’re researching, the more email addresses Hunter will have found. For very niche sites, it can become a bit hit and miss as to whether Hunter has any email addresses, but I’d say even then it is 70/30 in favour of Hunter. 

I’d recommend trying it out for free and seeing how much use you get out of it.

There is a free version which limits you to 25 searches per month, and the cheapest paid plan (Starter) is €49/month for 500 monthly searches. The free version of Hunter allows 500 emails per month and the Starter plan includes 2,500.
