FirstMark Data vs Hunter.io
New business emails vs existing business emails

Hunter.io finds email addresses for companies that already exist. FirstMark Data finds email addresses for businesses that just launched - companies that Hunter.io has never crawled and cannot find yet.

Quick answer: Hunter.io and FirstMark Data both provide verified email addresses, but from completely different sources. Hunter.io crawls existing websites to find publicly listed email addresses. FirstMark Data processes business registration data to surface emails from businesses that launched in the last 30 days - businesses whose websites have not been crawled by Hunter.io yet. If you want to email new businesses before any competitor does, FirstMark Data has what Hunter.io cannot provide.

When to use FirstMark Data vs Hunter.io

FirstMark Data

Use for new business email outreach

You want to email businesses the day they launch. A new business registered today - they need a web designer, an accountant, a marketing tool. FirstMark Data has their verified email address already. Hunter.io does not and will not for weeks.
Hunter.io

Use for finding emails at known companies

You want to email someone at an existing company - say the Head of Marketing at a firm that has been around for 3 years. Hunter.io crawls their website and finds the email pattern and available addresses. This is what Hunter.io does best.

How Hunter.io finds emails and why new businesses are invisible to it

Hunter.io is a web crawler. It visits websites, finds email addresses listed publicly, and indexes them. This works well for established companies that have had time to build a web presence. But for new businesses, it creates a significant gap.

FirstMark Data bypasses all of this. We process business registration records directly, surfacing contact data from the registration itself rather than waiting for web crawlers to catch up.

What FirstMark Data provides that Hunter.io cannot

FirstMark Data vs Hunter.io - common questions

Is FirstMark Data a Hunter.io alternative?
FirstMark Data fills a gap that Hunter.io cannot cover. Hunter.io finds emails for existing companies through web crawling. FirstMark Data finds emails for businesses that launched in the last 30 days through business registration data - companies whose websites have not been crawled by Hunter.io yet. For new business email outreach, FirstMark Data has no equivalent.
Can I use FirstMark Data and Hunter.io together?
Yes. Use FirstMark Data to find and email new businesses the day they launch. Once those businesses are established and have a web presence, they will appear in Hunter.io. Use Hunter.io to find additional contacts at those companies beyond the founding contact. The two tools cover different stages of a business's life.
Does FirstMark Data have bulk email finding like Hunter.io?
FirstMark Data works differently. Instead of searching for emails at a known domain, you browse a daily feed of newly launched businesses and reveal emails on demand. You can also use bulk reveal to reveal multiple contacts at once, and export your revealed contacts via CSV for use in your outreach tool.
Are the emails on FirstMark Data verified?
Yes. All revealed email addresses are verified via MillionVerifier, one of the leading email verification APIs. The verification result (valid, invalid, or catch-all) is shown alongside each email. If an email is verified as invalid, the reveal credit is refunded automatically.
What is the free plan like on FirstMark Data compared to Hunter.io?
FirstMark Data's free plan gives you 300 credits per month with no credit card required. Each credit reveals one email or one phone number. Free users can access businesses that launched 15 to 30 days ago. Hunter.io's free plan offers 25 searches per month. FirstMark Data's free plan is significantly more generous for testing the platform.
