These are the three complaints Hunter reviewers repeat most.

It can't find emails for many people, especially at smaller companies.

“Hunter occasionally provides incomplete results or fails to return any information for certain domains, particularly when it comes to newer or smaller companies.”G2, 4.5 stars, 11 Dec 2025
“Just not enough Email addresses.”Trustpilot, 1 star, 29 Apr 2026
On EmailchaserEmailchaser found 88 of 100 contacts in our August 2026 test versus 67 for Hunter. Lead Finder searches people by job title, seniority, industry, company size and location, and one credit reveals one contact.

Some emails are out of date, or bounce even when marked verified.

“The biggest weakness is depth and freshness.”G2, 4 stars, 5 Nov 2025
“every now and then the confidence score feels higher than what the real world bounce rate shows.”G2, 5 stars, 11 Dec 2025
On EmailchaserEvery address can get up to two independent checks and comes back valid, catch-all, invalid or unknown. Turn on Filter invalid emails in a campaign and bad addresses are left out before anything sends.

Costs climb as you grow, from credits to mailboxes to warm-up.

“It can get expensive for bulk use”G2, 3 stars, 27 Jan 2026
“They want to charge $6 per account for just warming up your emails and maintain their reputation.”Trustpilot, 1 star, 22 Sep 2026
On EmailchaserWarm-up comes with every plan at no extra cost, and you can connect as many mailboxes as you like. Sending 25,000 emails to 2,500 new leads a month takes 17 mailboxes at 50 emails a day each, which costs $219 on Hunter (Growth $149 + 7 extra mailboxes $70) and $105.50 on Emailchaser Pro, every address checked.

This is what Hunter reviewers like, and Emailchaser does it too.

It saves hours of searching for email addresses.

“It saves me a significant amount of time that I would otherwise spend manually searching and verifying emails”G2, 4 stars, 30 Dec 2025
On Emailchaser tooLead Finder searches people by job title, seniority, industry, company size and location, shows their email addresses, and adds the people you pick straight to a campaign.

Checking an address before you send cuts bounces.

“Having the ability to confirm whether an email address is valid before reaching out helps lower bounce rates and makes outreach efforts more effective.”G2, 4.5 stars, 19 Dec 2025
On Emailchaser tooThe email verifier checks a pasted or uploaded list, marks every address valid, catch-all, invalid or unknown, and gives you the results as a CSV. You pay only for the addresses you check.

Our verdict: Hunter is quick and simple, but its reviewers keep running into missing emails and rising costs.

  • G2 reviewers rate it 4.4 from 656 reviews, mostly for how quick and simple it is.
  • In our test of 100 contacts, Emailchaser found 88 emails and Hunter 67.
  • If you want to find leads, check them and email them in one plan, Emailchaser includes 1,500 to 10,000 lead credits a month, warm-up and unlimited mailboxes, from $47 a month.
