Hunter.io and Apollo: the popular picks
Hunter.io turns a company domain into its work emails, each with a source and score, but returns no phone numbers. Apollo goes wider: a large database with sequencing and dialing, a roomy free email tier but thin phone credits, and plans auto-renew. See our Hunter.io alternatives.
Snov.io, RocketReach and ZoomInfo
Snov.io is a budget all-in-one — finder, verifier and sequences — with credits that roll over but no refunds. RocketReach is a broad reverse-lookup database, phone on higher tiers, weak support. ZoomInfo is the enterprise heavyweight: strong North American dials, but annual-only.
The number on the box is a trap
Headline database size is the least useful spec. A directory of hundreds of millions can still miss the dozen buyers you're chasing this quarter, so pilot on your own list first.
How to choose
- Domains in hand, emails only: Hunter.io.
- Database plus sending: Apollo.
- Budget all-in-one: Snov.io or RocketReach.
- Enterprise, North America: ZoomInfo.

FAQ
Which free tier is most usable?
Apollo's free email allowance is the roomiest; Hunter.io and Snov.io refill modestly; ZoomInfo Lite and RocketReach less so. None judges data quality — pilot on a real list first.
Do I need a company email to sign up?
Several, including Hunter.io and ZoomInfo, require a company-domain email at signup, which can rule a tool out for a solo seller.
What if a tool can't find the contact I need?
On a subscription you've paid for the month regardless, and a miss burns a credit. Pay-per-result flips that: an empty search costs nothing.
