# Search by email address: the best email lookup tools for work emails, compared on price and limits

We read eight vendors' pricing pages and docs on October 16, 2026, and compared them with Enrich.chat. See which tools find the person behind a work email, what a lookup and a miss cost, and how an AI agent connects.

By Enrich.chat Editorial. Updated October 16, 2026.

**Short answer:** The right email lookup tool depends on the direction. For a work email in and a person out, or a name and company website in and a work email out, [Enrich.chat](https://enrich.chat/pricing/) gives 10 lookups a day with no signup, then plans from $29. [Hunter](https://hunter.io/pricing) charges 0.2 credits per enrichment, and [Mailmeteor](https://mailmeteor.com/tools/reverse-email-lookup) is a free one-off check.

## Key takeaways

- Eight of the nine tools look up a person from an email address. ZeroBounce only goes the other way, from a name and a domain to an email.
- A matched lookup costs 0.2 credits on Hunter, 1 on Apollo and Prospeo, and 10 on Icypeas and Enrich.chat. Priced from entry plans, 1,000 lookups are $4.90 on Hunter, $24.50 on Prospeo, $26.00 on Apollo, $190.00 on Icypeas and $2.90 on Enrich.chat.
- Lusha's API takes at least 1 credit per request, even when nothing comes back. The other tools charge only for a match or a full result.
- Mailmeteor's free page and Enrich.chat's 10 daily lookups need no signup. Eight of the nine list an MCP connection, and the Enrich.chat server needs no key.
- This page covers work emails. A personal mailbox has no public owner record, and Enrich.chat does not look one up.

## The verdict

For people who look up work emails from inside AI agents and apps, **Enrich.chat** is the pick: one prompt, no key to start, unlimited seats, and credits spent only on matches. For a free one-off check, enrichment inside a sales plan or a LinkedIn URL from an email, one of the other eight fits better.

- Best for AI agents and apps: Enrich.chat (No key to start, MCP server, plans from $29)
- Best for API enrichment on a prospecting plan: Hunter (0.2 credits per enrichment, MCP on all plans)
- Best all-in-one sales app: Apollo (Database, sequences and an enrichment API per seat)
- Best for a LinkedIn URL from an email: Icypeas (Reverse lookup from $19 a month, 50 per bulk request)
- Best for a free one-off check: Mailmeteor (No sign-up, name and company from a work email)

## What does an email lookup tool do?

An email lookup tool takes what you have and returns what you lack. Three different jobs share the name, and Figure 1 separates them. This page compares tools for the first two, for work addresses only: finding the person behind an email address, and finding a work email from a name and a company website.

**Figure 1: Three jobs that share the name email lookup.** Three columns. A reverse lookup takes an email address and returns a name, title and company, and Enrich.chat does it with GET /v1/person and an email. An email finder takes a name and a company website and returns a work email with a status, and Enrich.chat does it with GET /v1/person and a name and company. An email verifier takes an email address and says whether the mailbox exists, and Enrich.chat has no standalone verifier. The first two jobs are compared on this page.

*The three jobs people call email lookup. This page compares the first two for work addresses. The addresses are fictional, on a domain reserved for examples, and the Enrich.chat endpoints follow [agents.md](https://enrich.chat/agents.md).*

The third job, checking whether a mailbox exists, needs a different tool. Our guide to [email verification tools](https://enrich.chat/blog/email-verification-tools/) compares those. For how a reverse lookup works and which free checks help, read our guide to [reverse email lookup](https://enrich.chat/blog/reverse-email-lookup/). If a suspicious message brought you here, start with [who owns this email address](https://enrich.chat/blog/who-owns-this-email-address/).

Work addresses give lookup tools more to go on than personal ones. [Icypeas's guide](https://www.icypeas.com/blog/24-best-reverse-email-lookup-tools-free-paid) says work emails carry more identifying information than personal emails. [Mailmeteor's FAQ](https://mailmeteor.com/tools/reverse-email-lookup) says addresses at Gmail, Yahoo and Outlook may return limited information. So this page covers business use and leaves out people-search sites. For example, [YouGetSignal's reverse e-mail page](https://www.yougetsignal.com/tools/reverse-email-lookup/) hands the search to a people-search service and describes paid background records. Checking a supplier or a sign-up is different from profiling a private person, and the tools below are built for the first.

## How did we choose and rank these nine email lookup tools?

We kept tools whose own pages document a lookup from an email address to a person, or from a name to a work email, and publish a price. We ranked them for people who look up work addresses from an AI agent or an app. Four things set the order: what a lookup costs, what a miss costs, how an agent connects, and the contract terms.

We left out tools that sell data only by quote, and people-search, breach-check and social-matching sites that aim at private mailboxes. Vendor blogs also publish match-rate tests, each on a different sample, so this page repeats none of them. Enrich.chat is our product, and it ranks first for agents and apps. Its limits are listed in the same format as every other tool's.

## How much does an email lookup cost?

A matched lookup costs 0.2 credits on [Hunter](https://help.hunter.io/en/articles/1970956-hunter-api), 1 on [Apollo](https://docs.apollo.io/reference/people-enrichment) and [Prospeo](https://prospeo.io/api-docs/enrich-person), and 10 on [Icypeas](https://www.icypeas.com/pricing) and Enrich.chat. Credits differ in size, so Figure 2 divides each entry plan's monthly price by its credits to price 1,000 matched lookups, as checked on October 16, 2026.

**Figure 2: Pro-rated cost of 1,000 matched email-to-person lookups on each entry plan.** Bar chart of each entry plan price divided by its credits, for 1,000 matched lookups that return a person from an email address, checked October 16, 2026. Enrich.chat costs $2.90 at 10 credits a match on the Growth plan. Hunter costs $4.90 at 0.2 credits, Prospeo $24.50, Apollo $26.00 and Icypeas $190.00 at 10 credits a found profile. Findymail, Lusha, ZeroBounce and Mailmeteor have no bar.

*Entry plan price divided by its credits, for 1,000 matched lookups that return a person from an email address, checked October 16, 2026. It is pro-rated maths, not a bill: you pay the full plan price. Apollo and Prospeo prices are per seat or user, and Icypeas excludes VAT. Sources: [Enrich.chat](https://enrich.chat/pricing/), [Hunter](https://help.hunter.io/en/articles/1970956-hunter-api), [Prospeo](https://prospeo.io/api-docs/enrich-person), [Apollo](https://docs.apollo.io/reference/people-enrichment) and [Icypeas](https://www.icypeas.com/pricing).*

The chart assumes every credit goes to lookups that return a person. [Hunter's Starter plan](https://hunter.io/pricing) is $49 a month for 2,000 credits, and its help center charges 0.2 credits only when the email, full name and position all come back. [Apollo Basic](https://www.apollo.io/pricing) is $65 a seat a month billed monthly for 2,500 credits. [Prospeo Starter](https://prospeo.io/pricing) is $49 a user for 2,000 credits, and [Icypeas Basic](https://www.icypeas.com/pricing) is $19 plus VAT for 1,000. Enrich.chat's Growth plan is $29 for 100,000 credits.

Four tools have no bar. [Findymail's](https://www.findymail.com/pricing) usage plans start at $99 a month and publish no credit count. [Lusha](https://docs.lusha.com/user-guide/usage-analytics/how-credits-are-counted) bills by what you reveal: 1 credit per API result, 1 per email and 5 per phone. [ZeroBounce](https://www.zerobounce.net/pricing/) goes from a name to an email only, at 20 credits per verified result. [Mailmeteor](https://mailmeteor.com/tools/reverse-email-lookup) is free. Our pricing guides cover [Hunter](https://enrich.chat/blog/hunter-io-pricing/), [Apollo](https://enrich.chat/blog/apollo-pricing/), [Prospeo](https://enrich.chat/blog/prospeo-pricing/), [Lusha](https://enrich.chat/blog/lusha-pricing/) and [ZeroBounce](https://enrich.chat/blog/zerobounce-pricing/) in more detail.

The table shows what each lookup from an email address returns, and when it spends credits.

*What a lookup returns and what it costs, from each vendor's own pages, checked October 16, 2026.*

| Tool | What a lookup returns | What costs credits | What is free |
| --- | --- | --- | --- |
| Enrich.chat | Name, title, company, LinkedIn URL and the email's status | A match: 10 credits | A lookup that finds nothing: 0 credits; 10 lookups a day with no signup |
| Hunter | Name, location, social handles and employment ([API docs](https://hunter.io/api-documentation/v2)) | 0.2 credits when the email, full name and position return ([help center](https://help.hunter.io/en/articles/1970956-hunter-api)) | A call that returns less than those three |
| Prospeo | Person data, company data and email ([API docs](https://prospeo.io/api-docs/enrich-person)) | 1 credit per email found, 10 per mobile | No match, and the same record again within 90 days |
| Apollo | Person and company data; email and mobile only when you ask ([API docs](https://docs.apollo.io/reference/people-enrichment)) | 1 credit for demographics or an email, plus 8 for a mobile | 0 credits when nothing credit-consuming is found |
| Findymail | A LinkedIn URL, or the full profile ([API docs](https://app.findymail.com/docs/)) | 1 finder credit, or 2 with the full profile, when a profile is found | A lookup that finds no profile |
| Icypeas | The profile URL behind the address ([API docs](https://api-doc.icypeas.com/reverse-email-lookup/)) | 10 credits per found profile | A lookup that finds no profile |
| Lusha | Matches, and what is available on each ([API overview](https://docs.lusha.com/apis/openapi/contact-search-and-enrich)) | 1 credit per API result, 1 per email, 5 per phone, at least 1 per request ([credits guide](https://docs.lusha.com/user-guide/usage-analytics/how-credits-are-counted)) | Platform searches and unmatched CSV rows |
| ZeroBounce | No person: it returns a work email from a name and a domain ([API page](https://www.zerobounce.net/apis/email-finder-api)) | 20 credits per verified email | Unknown results; 10 finder queries a month on the free plan |
| Mailmeteor | Name, job title, company and social profiles ([tool page](https://mailmeteor.com/tools/reverse-email-lookup)) | Nothing | The whole tool, with no sign-up |

A month with 500 reverse lookups needs 5,000 Enrich.chat credits. That fits the Growth plan at $29 a month with unlimited seats, and pro-rated the lookups are worth $1.45 of the plan. Adding a mobile for 100 of those people takes the month to 30,000 credits, which still fits the Growth plan at $29 a month.

## What happens when an email lookup finds nothing?

Only Lusha's API says it charges for a request that returns nothing: its [credits guide](https://docs.lusha.com/user-guide/usage-analytics/how-credits-are-counted) sets a minimum of 1 credit per request. Enrich.chat uses 0 credits on a miss. Hunter, Apollo, Prospeo, Findymail, Icypeas and ZeroBounce each say they charge only for a match or a full result.

A maybe costs more than a miss. A name-to-email finder can return an address on a domain that accepts every message, and nobody can confirm a mailbox there. [Hunter's guide](https://hunter.io/email-verification-guide/accept-all-catch-all/) says emails to accept-all addresses are about 27 times more likely to bounce than emails to valid ones, and suggests keeping them to 2% to 5% of a campaign. Enrich.chat labels these `catch_all`, Hunter labels them `accept_all`, and [Mailmeteor's finder](https://mailmeteor.com/tools/email-finder) labels results Valid, Risky or Not Found. Our [catch-all checker](https://enrich.chat/tools/catch-all-checker/) tests a domain, and [what is a catch-all email](https://enrich.chat/blog/what-is-a-catch-all-email/) explains the risk.

## Which email lookup tools work inside AI agents?

Eight of the nine list an MCP connection, and only Enrich.chat's needs no account for its first 10 lookups a day. Mailmeteor is a web page and lists no API or MCP server. The table shows what each vendor says you need first.

*How an agent connects to each tool, from the vendors' own pages, checked October 16, 2026.*

| Tool | How an agent connects | What you need first |
| --- | --- | --- |
| Enrich.chat | MCP server at `enrich.chat/mcp`, or one prompt that reads [agents.md](https://enrich.chat/agents.md) | Nothing for the first 10 lookups a day |
| Hunter | [MCP server](https://hunter.io/mcp), included on all plans | A Hunter account |
| Prospeo | [Hosted MCP server](https://prospeo.io/mcp) at `mcp.prospeo.io`, included in every plan | A Prospeo account, with an API key or OAuth |
| Apollo | [MCP server](https://docs.apollo.io/docs/apollo-mcp) through ChatGPT, Claude, Cursor and other clients | An active Apollo account and credits |
| Findymail | API and MCP access listed on [every plan](https://www.findymail.com/pricing) | An account; setup steps are not on the pricing page |
| Icypeas | MCP listed on every plan of its [pricing page](https://www.icypeas.com/pricing) | An account; setup steps are not on the pricing page |
| Lusha | [MCP server](https://docs.lusha.com/user-guide/mcp/lusha-model-context-protocol-mcp-server), with OAuth in Claude, ChatGPT and Codex and an API key elsewhere | A Lusha account on any plan; MCP calls use credits |
| ZeroBounce | [Official open-source MCP server](https://www.zerobounce.net/mcp) | A ZeroBounce account and API key; actions use credits |
| Mailmeteor | A web page; no API or MCP server is listed | Nothing |

To use Enrich.chat, add the MCP server at `https://enrich.chat/mcp` to ChatGPT, Claude, Cursor or VS Code, or paste a prompt that sends your agent to [agents.md](https://enrich.chat/agents.md). The [install page](https://enrich.chat/install/) lists the steps. For more agent-ready tools, see the [best MCP servers for sales](https://enrich.chat/blog/best-mcp-servers-for-sales/).

## How does Enrich.chat look up a work email?

Enrich.chat's `GET /v1/person` endpoint takes a work email and returns the person's name, title and company, or takes a name and a company website and returns a work email with a status. Both cost 10 credits on a match and 0 when nothing is found. The first 10 lookups a day need no signup and no key. The [people enrichment API](https://enrich.chat/api/person-enrichment/) page lists every endpoint.

### Email in, person out

Send the work address. This example uses a fictional person on example.com, so the response is illustrative.

```
GET https://enrich.chat/v1/person?email=dana.lee@example.com&fields=email,profile

{
  "found": true,
  "name": "Dana Lee",
  "title": "Head of Procurement",
  "company": {"name": "Example Co"},
  "linkedin_url": "https://www.linkedin.com/in/dana-lee-example",
  "work_email": {"value": "dana.lee@example.com", "status": "verified"},
  "credits_used": 10,
  "free_lookups_remaining": 9
}
```

Figure 3 marks what each field means. A miss returns `{"found": false}` and uses nothing. Personal mailboxes such as Gmail are not looked up.

**Figure 3: An annotated Enrich.chat lookup response.** An illustrative JSON response for a fictional person on example.com. The found field is true, and a miss would return false and use 0 credits. The name, title and company come with the email match. The work email has a status of verified, catch_all or unknown. The lookup used 10 credits, and the free tier shows 9 free lookups remaining.

*An illustrative response for a fictional person on example.com. The fields follow [Enrich.chat's agents.md](https://enrich.chat/agents.md). On the free tier nothing is charged, and `free_lookups_remaining` counts down from 10.*

### Name and company website in, work email out

Send the full name and the company's website, not its name. The status here is `catch_all`, so the domain accepts every address and the mailbox cannot be confirmed. Treat it as risky.

```
GET https://enrich.chat/v1/person?name=Dana%20Lee&company=example.com&fields=email

{
  "found": true,
  "work_email": {"value": "dana.lee@example.com", "status": "catch_all"},
  "credits_used": 10,
  "free_lookups_remaining": 9
}
```

The free [email finder](https://enrich.chat/tools/email-finder/) runs this kind of lookup in a browser, and the [email finder API](https://enrich.chat/api/email-finder/) page covers it in code. Anyone can opt out of Enrich.chat at the [opt-out page](https://enrich.chat/opt-out/).

### What Enrich.chat does not do

- **Work emails only.** A personal mailbox is refused, and a company must be a website, not a name.
- **One lookup per call.** Pace requests at about one a second. On self-serve plans there is no bulk upload or export and no saved lists.
- **No extras.** There is no Chrome extension, sequencer or dialer, and no standalone verifier for emails from other tools.
- **Records, not proof.** A match shows whom an address belongs to in records, not who sent a message. People change jobs, so treat each contact as a strong lead, not a guarantee.

Paste this prompt into an agent that can call the API or the MCP server. The plans are on the [pricing page](https://enrich.chat/pricing/).

## What should you check before you pick an email lookup tool?

Check six things. Each can change the real cost or the risk more than the list price does.

1. **The direction.** ZeroBounce only goes from a name to an email, and Mailmeteor runs its lookup and its finder as two separate pages. Check that the tool documents the lookup you need.
2. **What a miss and a maybe cost.** Lusha's API takes a credit even for an empty result. A catch-all result may bounce, so ask how the tool labels it.
3. **Personal mailboxes.** [Findymail's API docs](https://app.findymail.com/docs/) say its reverse lookup takes a work or personal email. [Prospeo's docs](https://prospeo.io/api-docs/enrich-person) describe the email field as the person's work email, and Enrich.chat refuses personal mailboxes. Set your own policy before you connect an agent.
4. **Seats and credit expiry.** Apollo and Prospeo price per seat or user. Hunter says its plans include unlimited team members, and so does Enrich.chat. Hunter's credits reset monthly and do not roll over, and Enrich.chat credits renew with each monthly payment and do not roll over.
5. **How it performs on your records.** Run 100 contacts whose details you know through two tools and score every result. People change jobs, so repeat the test before you renew: see [B2B data decay](https://enrich.chat/blog/b2b-data-decay/).
6. **The rules for using a match.** The [ICO says](https://ico.org.uk/for-organisations/direct-marketing-and-privacy-and-electronic-communications/business-to-business-marketing/) the UK GDPR applies when you process personal data for direct marketing, even in a business context. A named work address is personal data. Our guide to [who owns this email address](https://enrich.chat/blog/who-owns-this-email-address/) covers the notice duty, and [cold email data](https://enrich.chat/blog/cold-email/) covers sending. This is not legal advice, and no data tool makes your use compliant.

## When is Hunter, Apollo or another tool the better choice?

Another tool is the better choice when you need outreach, a sales database, phone numbers one contact at a time, LinkedIn URLs in bulk, or a free check with nothing to set up.

- **Hunter** when you also prospect and send cold email from one app. Its [pricing page](https://hunter.io/pricing) lists sequences, browser extensions and a Google Sheets add-on. See [Hunter pricing](https://enrich.chat/blog/hunter-io-pricing/) and [Hunter alternatives](https://enrich.chat/alternatives/hunter-io/).
- **Prospeo** when you want to search by filter and enrich in one tool. Its [Starter plan](https://prospeo.io/pricing) lists CSV and API enrichment and a Chrome extension. See [Prospeo pricing](https://enrich.chat/blog/prospeo-pricing/).
- **Apollo** when reps want a database, sequences and calls in one seat. Its [Free plan](https://www.apollo.io/pricing) lists API access, two sequences and Gmail and Salesforce extensions. See [Apollo pricing](https://enrich.chat/blog/apollo-pricing/) and [Apollo alternatives](https://enrich.chat/alternatives/apollo/).
- **Findymail** when you want a phone finder next to the email lookup on a fixed monthly plan. Its [pricing page](https://www.findymail.com/pricing) lists API and MCP access on all plans.
- **Icypeas** when you need LinkedIn profile URLs for many work emails. Its [API](https://api-doc.icypeas.com/reverse-email-lookup/) takes up to 50 addresses per request.
- **Lusha** when a rep reveals phone numbers one contact at a time. Its [credits guide](https://docs.lusha.com/user-guide/usage-analytics/how-credits-are-counted) prices a phone at 5 credits. See [Lusha pricing](https://enrich.chat/blog/lusha-pricing/) and [Lusha alternatives](https://enrich.chat/alternatives/lusha/).
- **ZeroBounce** when you already validate lists there and want to find addresses on the same credits. See [ZeroBounce pricing](https://enrich.chat/blog/zerobounce-pricing/).
- **Mailmeteor** when you need one free check on a single work address and nothing to install.

For finding emails from names in bulk, see the [best email finder tools](https://enrich.chat/blog/best-email-finder-tools/). For LinkedIn URLs in, see the [best LinkedIn email finders](https://enrich.chat/blog/best-linkedin-email-finder/).

## Frequently asked questions

### How do I look up information on an email address?

For a work email, use a reverse email lookup tool. Paste the address into a free page such as [Mailmeteor's](https://mailmeteor.com/tools/reverse-email-lookup), or call an API such as [Enrich.chat's](https://enrich.chat/api/person-enrichment/), and it returns a name, title and company when it has a match. Personal mailboxes such as Gmail have no public owner record, so this guide covers work addresses only. Our guide to [reverse email lookup](https://enrich.chat/blog/reverse-email-lookup/) explains the method.

### Is there a free email lookup tool?

Yes. [Mailmeteor](https://mailmeteor.com/tools/reverse-email-lookup) has a free reverse lookup page with no sign-up, and Enrich.chat gives 10 lookups a day with no signup. [Hunter](https://hunter.io/pricing) gives 50 credits a month, [Prospeo](https://prospeo.io/pricing) 100, [Lusha](https://www.lusha.com/pricing/) 40 and [Apollo](https://www.apollo.io/pricing) 75 per seat, as of October 16, 2026. Our free [email finder](https://enrich.chat/tools/email-finder/) goes from a name to an email.

### Can I find a person by email address?

Yes, for a work address. Send it to a reverse lookup such as [Hunter's Email Enrichment](https://hunter.io/api-documentation/v2) or Enrich.chat's `GET /v1/person?email=`, and you get a name, title and company when a record matches. A match shows whom the address belongs to in records, not who sent a message. See [who owns this email address](https://enrich.chat/blog/who-owns-this-email-address/) for the safe checks.

### How much does an email lookup cost?

A matched lookup costs 0.2 credits on [Hunter](https://help.hunter.io/en/articles/1970956-hunter-api), 1 on [Apollo](https://docs.apollo.io/reference/people-enrichment) and [Prospeo](https://prospeo.io/api-docs/enrich-person), and 10 on [Icypeas](https://www.icypeas.com/pricing) and Enrich.chat. Entry plans billed monthly run from $19 on Icypeas to $99 on Findymail, with Enrich.chat's Growth plan at $29. 500 reverse lookups a month need 5,000 Enrich.chat credits, which fits the Growth plan at $29 a month. See [pricing](https://enrich.chat/pricing/).

### Do email lookup tools charge when they find nothing?

Most do not. Enrich.chat, Hunter, Apollo, Prospeo, Findymail and Icypeas charge only for a match, and ZeroBounce charges nothing for unknown results. [Lusha's API](https://docs.lusha.com/user-guide/usage-analytics/how-credits-are-counted) takes at least 1 credit per request, even when no results come back. Check what a tool bills for risky results too, because those are the emails most likely to bounce.

### Can an AI agent look up an email address?

Yes. Eight of the nine tools list an MCP connection. The Enrich.chat MCP server at enrich.chat/mcp needs no key, and the first 10 lookups a day need no signup. [Hunter](https://hunter.io/mcp) includes MCP on all plans, [Prospeo](https://prospeo.io/mcp) hosts a server at mcp.prospeo.io, and [Apollo](https://docs.apollo.io/docs/apollo-mcp) connects over OAuth. See the [best MCP servers for sales](https://enrich.chat/blog/best-mcp-servers-for-sales/).
