Best email finder tools, and which one fits your workflow

How we compared

An email finder takes a name, a company or a LinkedIn profile and returns a work email you can send to. We judged each tool on five things a buyer in this category actually feels:

1. Input fit. Can you start from a LinkedIn profile, a name and company, or a list?
2. Verification. Does the tool check the mailbox, and does it label uncertain results honestly? Catch-all domains matter here; see what a catch-all email is.
3. Price for a small start. The free allowance and the first paid plan, as each vendor publishes them.
4. Extras you may need. Phone numbers, sequencing and CRM sync.
5. Programmatic access. API and MCP, for people who want an agent or script to do the lookups.

Vendor facts below come from each company's own pages, checked on 2026-11-09. Accuracy figures are the vendors' own claims unless marked third-party. We left ZoomInfo out. It is a broad go-to-market platform, and its main platform pricing is not published, so it fits a sales intelligence comparison better than a list of email finders. It is covered in our sales intelligence tools roundup.

The tools, in order of fit

The order reflects fit for the typical email-finder buyer: someone with a profile or a name who wants a deliverable work email quickly. It is not a quality ranking.

1. Wiza. Wiza is built around this job. Wiza says it verifies at request time with syntax, domain, MX, SMTP, catch-all and disposable checks. It labels results valid or risky, and charges only for valid ones. Wiza says risky emails have 50 to 70% deliverability. It claims 850M+ contacts and 99%+ deliverability. Plans are per user, and monthly plans bill overage automatically ($0.15 per valid email). The annual "unlimited" plans cap bulk exports at 2,500 a month and reveals at 500 per 24 hours. Wiza also sells one-off API credits at $0.025 each, with a minimum of 2,000 ($50).

2. Apollo. Apollo pairs an email finder with a full sales platform: database, sequences, a dialer and CRM integrations. Apollo says it has 240M+ contacts and a 98% email accuracy rate from seven-step verification. The steps themselves are not published. The free plan gives 100 credits per seat per month, and an email costs 1 credit. Unused credits expire each billing cycle. Its MCP server and Claude and ChatGPT connectors are available on any plan, including Free. For a cost breakdown, see Apollo pricing.

3. Lusha. Lusha is a strong fit if you need phones alongside emails. Lusha claims 98% email accuracy and 86% global phone accuracy. Third-party reviews estimate its email accuracy lower, at around 75 to 81%. Emails carry a confidence tier (A1 to A4) and an update date. Lusha charges a minimum of 1 credit per request even when no data comes back. Monthly plans roll unused credits over up to 2x.

4. Leadsets. Leadsets is a B2B data API and remote MCP server rather than a click-to-reveal tool, so it fits buyers whose agent or code does the finding. enrich_person returns current role, company and a verified work email when one exists. Every email goes through a verification waterfall and is labelled verified, catch-all, unknown or invalid, with a confidence score and a checked date. Pricing is flat (Solo $29, Pro $99, Team $399, Max $999 a month) with fair-use limits, and records only count when data comes back. Leadsets has no phone numbers yet, and SOC 2 Type I is planned for Q3 2027 rather than done.

5. Clay. Clay is a workflow platform that runs waterfalls across many providers. Clay says it has 50+ built-in providers on one page and 150+ on others, including Wiza, Lusha and Apollo. It says waterfalls routinely triple customers' data coverage. Clay's official verification method is not published. Community answers say it validates with ZeroBounce by default and counts catch-alls as valid unless "only mark safe to send" is enabled. Clay suits builders who want coverage across vendors and are comfortable with a spreadsheet-style workflow tool.

Best email finder for LinkedIn

If you start from LinkedIn, the browser extension matters most:

• Wiza recommends LinkedIn URLs as API input and has a Chrome extension for profiles and company websites. Since August 19, 2026, bulk export from LinkedIn, Sales Navigator and Recruiter search pages is removed. The extension now works on individual profiles only.
• Apollo includes a Chrome extension on all plans, including Free.
• Lusha offers a Chrome and Edge extension, with phones classed as mobile, direct or general.
• Leadsets has no extension. Its free "Enrich a contact from a LinkedIn URL" skill lets Claude or ChatGPT enrich one profile URL or a batch through enrich_person. That suits a list of URLs more than clicking through profiles.

For a head-to-head on the LinkedIn use case, see Leadsets vs Wiza.

Example: 60 event contacts

Maya Chen, VP Revenue Operations at Northwind Analytics, has 60 LinkedIn URLs from a conference. They include contacts at Stackfold and Parcelry. She wants verified work emails before a sequence goes out.

• With Wiza, she opens each profile with the extension, or sends the URLs to the API. She pays only for valid emails. Wiza's free allowance of 20 valid emails would cover a third of the list.
• With Apollo or Lusha, she uses the extension or a list upload. Each email reveal costs 1 credit from her monthly balance.
• With Leadsets, she pastes the URLs into Claude with the Leadsets connector on. The agent calls enrich_person and returns a table split into verified, catch-all and unknown rows. This uses up to 60 of the 1,000 free records, and only rows that return data count.

If Maya also needs mobile numbers for a call block, Leadsets is not the right tool today. Wiza, Lusha or Apollo would be.

Which tool suits which buyer

• Recruiters and SDRs working profile by profile: Wiza or Lusha, for their extension-first workflows.
• Small teams wanting one free tool for finding and sending: Apollo, with its free plan and sequences.
• Anyone who needs phones: Lusha, Wiza or Apollo. Leadsets has none yet.
• Founders and GTM engineers using Claude, Cursor or n8n: Leadsets, for agent-ready verification labels and a flat price. See Leadsets pricing and MCP setup.
• Teams wanting the widest coverage across vendors: Clay waterfalls.
• Buyers who need SOC 2 today: Wiza, Apollo, Lusha and Clay each publish a SOC 2 Type 2 or Type II claim. Leadsets does not yet.

Questions and answers

What is the best email finder for LinkedIn?

Wiza is built around LinkedIn profiles, with a Chrome extension and LinkedIn URLs as its recommended API input. Since August 19, 2026, it works on individual profiles only, not bulk search pages. Apollo and Lusha also offer browser extensions, and Leadsets can enrich LinkedIn URLs through an AI agent or its API.

Is there a free email finder?

Most tools have a free tier. Wiza gives 20 valid emails once, and Apollo gives 100 credits per seat per month. Lusha gives up to 40 credits per month, Clay gives 500 actions and 100 data credits per month, and Leadsets gives 1,000 records once with no card.

How accurate are email finder tools?

Vendors publish their own figures. Apollo and Lusha each claim 98% email accuracy, and Wiza claims 99%+ deliverability. Third-party reviews estimate Lusha lower, at around 75 to 81%, and Leadsets publishes its benchmark method rather than promising 100%.

Should I send to catch-all emails?

A catch-all domain accepts every address, so no tool can confirm a specific mailbox exists. Send to these at lower volume and keep them separate from verified addresses. Wiza labels such results risky, and Leadsets labels them catch-all.

Can an AI agent find email addresses for me?

Yes, if the agent can call an email data source over MCP or an API. Wiza, Apollo, Lusha, Clay and Leadsets all publish MCP servers. Leadsets is built mainly for this use, returning verification status and checked dates the agent can act on.

Do email finders also find phone numbers?

Wiza, Lusha and Apollo return phone numbers, each charging more for a phone than an email. Clay offers phone enrichment from its Launch plan. Leadsets does not offer phone numbers yet.
