LeadMagic review (2026): the cheap, accurate first lookup
LeadMagic sells work emails, mobile numbers, and B2B profile data through one API at under 2 cents a credit. It answers less often than premium sources, but when it answers, it is usually right.
pipe0 buys data from LeadMagic and uses it in its waterfalls. The scores come from our own benchmark, not from that relationship. How we review
Our score for LeadMagic, the average of four criteria
One of the cheapest contact data APIs we use, with the most accurate email validation we tested and API, CLI, and MCP on every plan. Its lookup coverage trails premium sources.
Best for
- The first, cheapest step in an email or phone waterfall
- High-volume email finding on a budget
- Clay users who want a cheaper native provider
Skip it if
- You need the highest possible coverage from a single provider
- You want a free trial before you pay
- You need a prospecting app with sequences
A web app, a CLI, and a native Clay integration. Most teams call it from another tool rather than use it on its own.
Its answers agree with other providers 95% of the time on name and domain lookups. It finds fewer people than premium sources.
Credits from 2 cents down to under 1 cent, an email for 1 credit, misses free, and monthly credits that roll over up to twice.
API, CLI, and an MCP server with 130+ tools on every plan. The MCP server takes OAuth only, and most endpoints stop at 300 a minute.

LeadMagic in our benchmark
We run the same records through every provider we test. Below are LeadMagic's email verification results on 100 labelled addresses, then its contact data results, from July and October 2026.

How often LeadMagic agrees with other providers
Name and domain to work email. Each square is one person both providers returned a work email for.
Low-cost provider
vs Prospeo
91%20 of 22
LeadMagic and Prospeo returned the same work email for 20 of 22 people.
Premium provider
vs Amplemarket
95%21 of 22
LeadMagic and Amplemarket returned the same work email for 21 of 22 people.
- Name and domain are derived from each signup email, so this test measures finding a person's address format, not finding the company.
- LeadMagic's one rejected real address is the one every verifier rejected, most likely a labelling error, so it confirmed every other real address.
- Its two undetermined verdicts were unknown, which LeadMagic does not charge for, on fake addresses at salesforce.com and atlassian.com.
- Samples are small, 100 records per test, so treat a few points of difference as noise.
- Known-valid addresses are pipe0 users with a live Google sign-in in the last 45 days; known-invalid addresses are synthetic, with no person behind them.
- Catch-all, unknown, and risky verdicts count as undetermined, never as wrong. Only a fake passed as valid or a real address called invalid is an error.
- The signup set is real pipe0 signup emails with no vendor involved in choosing them, a harder and more realistic population than the profile set.
- Agreement is the share of results that match what other providers returned for the same person. It is a proxy for accuracy, not ground truth.

What is LeadMagic?
LeadMagic is a contact data API. Jesse Ouellette launched it in February 2024 after years of building data workflows for clients, and runs it without venture money from Needham, Massachusetts. One key covers work and personal emails, mobile numbers, LinkedIn profile enrichment, job change detection, company funding, technographics, and ad library search.
It has about 2,000 active subscribers, and many of them never need its web app: they call it from Clay, where it is a native provider, from n8n or Make, from their own code, or from an agent over MCP.
Where it fits
LeadMagic's data has a clear shape: when it answers, it is usually right, and it answers less often than the premium sources. In our name and domain test on 100 real pipe0 signups, it found a work email for half of them, and those addresses matched other providers 95% of the time. Against Amplemarket, a premium source, it agreed on 21 of 22 people.
That shape is exactly what the first slot of a waterfall needs. A waterfall stops at the first answer, so the first provider decides accuracy for every person it answers, and its price is paid on every lookup. A cheap provider that is right when it answers leaves only the remaining people for the expensive providers behind it.
What it costs
LeadMagic is among the cheapest contact data we buy. Credits cost about 2 cents on the smallest plan and 0.7 cents on the largest, a work email is 1 credit, and an empty lookup is free. Monthly plans let unused credits pile up to twice the monthly amount. Professional and Ultimate also make the search API free of credits.
There is no free trial; the smallest plan is $83 a month billed annually. One billing detail to watch: the job change detector costs 3 credits per person checked, even when nothing changed.
Email validation
LeadMagic also validates addresses, and that turned out to be its strongest product in our tests. We ran 100 labelled addresses through it: 50 real mailboxes of pipe0 users and 50 fakes, from random Gmail mailboxes to addresses at domains that don't exist. It got 97 right, ahead of ZeroBounce at 96, MixRank at 93, and MillionVerifier at 66.
It confirmed 49 of the 50 real addresses, and the one it rejected was rejected by every verifier, so that label is probably wrong. It passed no fake as valid. Where it couldn't tell, on two made-up addresses at salesforce.com and atlassian.com, it said unknown instead of guessing.
Validation costs a quarter credit per valid or invalid verdict, between 0.18 and 0.5 cents depending on the plan, and unknown results, including catch-all domains, are free. At about 2 seconds per check, it was the slowest of the four, so it suits batches better than a signup form. The full comparison is in our verification benchmark.
LeadMagic for agents
Every plan includes the API, a command-line tool, and an MCP server with more than 130 tools, which works in Claude, ChatGPT, Cursor, VS Code, and about a dozen other clients over OAuth. Email finding allows 600 requests a minute, which is plenty for an agent and enough for most batch jobs.
LeadMagic and pipe0
We buy data from LeadMagic, and it runs first in several pipe0 waterfalls, including name and domain to work email and email to LinkedIn profile. We put it there for the reasons above: low price and answers that agree with premium sources. The providers behind it pick up the people it doesn't find.
Who should buy LeadMagic
Buy LeadMagic if you enrich at volume, care about cost per result, and can put a second provider behind it for the people it misses.
Look elsewhere if you want the most coverage from a single provider. For work emails from names and domains, Hunter found more in our benchmark; for mobile numbers, Surfe did.
