List of the Best Reverse Email Lookup Tools

The Top 10 Email Lookup Tools

Below, we’ve identified and reviewed ten email lookup solutions you can try today, including the pros, cons, and top features of each one.

Disclaimer: Everything in this article was gleaned from research, including user reviews. We did not have time to manually test all the tools. This guide was last updated in Q3 2023. Please contact us to request any changes or corrections.



Best for Risk Management

Let’s start with a solution that works seamlessly for fraud prevention, risk management, and general business protection. SEON gives you extra data to make intelligent decisions about whether you should accept a user action or not.

That action could be a transaction or signup. Checking whether the user appears to exist or not is particularly useful as a pre-Know Your Customer (KYC) check, so you can avoid paying for the verification of junk users. For a transaction, you’re also protecting yourself from chargebacks.

SEON lets you know everything you need about the email address domain. Its key feature, however, is the reverse social media lookup, which finds whether the address has been used on 50+ social sites such as Facebook, Twitter,, Airbnb, and more, and gleans information from there.



  • Real-time results
  • API integration
  • Chrome extension
  • Reverse social media lookup


  • Cannot offer on-premise deployment
  • Features: SEON lets you perform complete user digital fingerprinting based on an email address, but also a phone number or IP address. It is one of the few tools that returns social media profiles as part of its results.
  • Best for: Risk analysis, pre-KYC checks
  • Pricing: Starts at $599. There is also a free version, no card required.


Pure People Research

Spokeo, founded in 2006, offers customers a comprehensive tool for doing background research on people and businesses. The California-based company started as a social media aggregator, then took that experience to its current product offering, which scans over 120 social sites for real-time user data, including dating sites, blog posts, and product reviews. In total, the data amounts to over 12 billion records to cross-reference. 

Though the service doesn’t provide automation, its reverse email lookup functionality can greatly aid manual lookups and fraud investigations to uncover signs of trustworthiness, or lack thereof.


  • Easy to use
  • No integration
  • Comprehensive


  • No automation
  • Can only be used manually
  • Limited searches per month
  • Features: The platform offers manual lookups based on email address, phone number, name, location, or username, generating comprehensive profiles from those data points.

  • Pricing: Three-tiered pricing with custom plans available: $19.95 for 100 monthly searches, $44.85 for a 3-month membership of 100 searches per month, and $66.95 for 500 monthly searches.



Great for Marketers – or Snovio – has all the features you might need for validating email addresses. It’s blazing fast, delivering results in under one minute. Like many other tools, it uses an SMTP-MX check to verify the deliverability of the address.

You can upload bulk addresses and export the results in CSV, XLSX, or Google Sheets formats. Another strong point is that this tool’s customer service gets loads of praise from users. Note that also has an email finder/email search function, which can be handy for marketers.


  • Easy to use
  • 150 free checks a month


  • Only email verification
  • Convoluted pricing model
  • Features: SMTP-MX check, fast results, API check, email finder

There are then five monthly plans depending on the number of credits you need, from 1,000 a month ($30) to 100,000 ($554 a month). Their custom package for outreach professionals starts at $999 per month.


Good for Background Checks (US only)

The free version of BeenVerified will give you email verification and a few more data points: In some cases, the person’s name from LinkedIn, and a check for two linked social media accounts (Twitter and LinkedIn).

It is for US use only and will trawl through legal documents to locate info on criminal records and bankruptcy reports. Each search takes between two and ten minutes. 

Although BeenVerified says checking is free, getting all the results is not. It costs $26.89 a month for up to 100 reports.


  • Checks criminal records in the US


  • Results fairly slow and US-centric
  • Features: Legal document check, basic social media check.
  • Best for: Checking on leads or potential hires.
  • Pricing: You’ll need the $26.89 monthly plan to get up to 100 reports each month.


Criminal Background Checks

CheckPeople offers both free and paid product models, with the paid version offering unlimited lookups. The software takes name, phone, or address data and conducts a thorough background search of available US public records, including criminal records, arrest records, previous aliases, and court appearances. Notably, this service currently only scrutinizes the United States and outlying territories.


  • Ease of use
  • Thorough US records checking


  • Only US background data

B2B Email Enrichment

Though most options on this list focus on background checks,’s reverse email lookups are designed for B2B marketing and sales.

After entering a business email address, the resulting data helps build a pipeline by segmenting customer bases, finding accurate contact information, generating customer profiles that can be valuable during sales pitches, and maintaining data hygiene.

Anymail Finder

Business and Personal Email Verification

The Anymail Finder product delivers a service that helps businesses maintain their marketing and sales email hygiene, maintaining low bounce rates and verifying corporate email addresses. Entering a business or corporate email address checks that address for signs of spam, invalid business domains, and disposable email addresses to make sure your demand-generating email lists are efficient, while also keeping your sender reputation high.


  • Simple tool for business email validation


  • Very specific use cases
  • Features: Corporate email lookups and validation, targeted email list generation, convenient Chrome extension.

Unlimited Subscription for Lookups

InfoTracer bundles all its services together with its unlimited plans, which means you’ll get reverse email search along with people lookup, background lookup, and court lookups.

The tool looks at public records, including criminal records and court records, along with a few social checks and vital records (birth, death, marriage, and divorce). You can also get a professional background check by looking at publicly listed licenses, such as a lawyer or electrician licenses.


  • Transparent pay-per-search pricing


  • For that price, seems very slow.
  • Features: Legal document check, basic social media check.
  • Best for: US background checks on potential hires, business partners or romantic interests.
  • Pricing: InfoTracer lets you pay per search: People Search ($1.50); Background Report ($20); Criminal Records Report ($5); Background Business Report ($25); UCC Search ($1.50); License Plate Verification ($5); Vehicle History Report ($9); Bankruptcies, Liens & Judgments Report ($5); Property Record Report ($5).


Lightweight Data Enrichment

A simple online tool, Spytox lets you look up by name or phone number, as well as email. The advantage is that it’s completely free and fairly fast, so it is ideal for ad-hoc searches.

Unfortunately, the tool didn’t seem to work 100% of the time during our testing, and the results were mixed in quality, rather than “explosive”, as the website promises.


  • Free
  • Works fairly fast (five seconds)


  • Success rate was really hit-and-miss during our tests
  • Features: Free for name and phone number lookup.
  • Best for: Free checks of single email addresses only.
  • Pricing: It’s completely free.


Sketchy US Service for Background Checks

RecordsFinder is so similar to BeenVerified and InfoTracer, one has to wonder if they’re not all run by the same people. In fact, you could pretty much copy and paste what we wrote about RecordsFinder’s two competitors and apply it here: Free check but expensive subscription to get results, US-centric, and good for background checks using public documents.


  • None, really


  • Shady business model
  • Expensive
  • Features: Free, search by name or phone number in the US.
  • Best for: Scanning public records.
  • Pricing: The pricing model is not as transparent as we have seen with other vendors. A single one-off report costs $2.95 and comes with seven-day unlimited access, but this is likely to be an introductory offer.

What Is a Reverse Email Lookup Tool?

A reverse email lookup tool lets you enter an email address and get its owner’s personal data. This usually includes a first and last name, but may also include a residential address, phone number, or social media handle. 

Reverse email lookup tools are a form of user fingerprinting, which let you attain extra information based on a limited number of data points. 

Reasons to rely on reverse email lookup tools include open source intelligence (OSINT), risk management, or marketing, among others.

How Do Reverse Email Lookup Tools Work?

Most of the time, you simply enter the email address into the search bar and press Enter. The results will appear directly on the website. Some providers also deliver PDF reports.

For more advanced lookups, you can use API calls or web browser extensions. You can also upload lists of email addresses via CSV file or Excel spreadsheet.

Why Use Reverse Email Lookup Tools?

Both companies and individuals rely on email search tools. They tend to use these solutions for three key reasons:

  • Marketing: For marketers or sales teams, it’s essential to check if the email addresses they have collected are valid. Because you don’t want your email marketing newsletters to bounce, it’s wise to confirm you’re dealing with real people as soon as possible.
  • Background checks: Usually performed by professionals who need more info about a potential hire, a prospect, or a business contact. Some individuals request them too, for every reason you can imagine, including getting the full picture about a new romantic interest, learning more about someone who got in touch out of the blue, or, unfortunately, cyberstalking.
  • Risk analysis: Small and large businesses use reverse email search to learn more about their users in the context of fraud prevention, risk assessment, and cybersecurity.

The above professionals are the most likely to employ these tools – but they can be equally useful to other businesses as well as to private individuals. Of course, not all these solutions are created equal. Let’s see what you should consider before signing up.

Six Key Points when Choosing a Reverse Email Lookup Tool

  1. What is my goal? Are you looking to create more complete customer profiles? Do you handle riskier transactions? Do you need more information on prospects or customers?
  2. How often will I need to use the tool? This may influence the kind of pricing model you should consider.
  3. How detailed do I need the results to be? This ties in with the goals of your queries, especially if you are in the risk management sphere.
  4. Does the tool comply with my legal data protection requirements? Obtaining data on users can put your company at risk if it’s done with the wrong tool.
  5. How fast can the results be delivered? Some people will require near-instant results, but some tools can take days to deliver results.
  6. Will I need additional information? Consider whether you need to deepen your search with a reverse phone lookup or IP analysis, for instance. Some tools offer this while others do not.

For this comparison article, we’ve tried to eliminate all the tools that were obviously out of scope based on the points above and the limits mentioned below.

What Data Can I Get From an Email Search Tool?

One advantage of using an email address to research user information is that this leads to email profiling that can reveal a vast amount of information associated with that address. This is why using these tools is also referred to as doing an “email background check”. They are also a lot more specific than, say, finding information about a device or IP address.

Email Address Validity

The first question a reverse email search can answer is whether the email address is real or not. This is verified using an SMTP check. The tool sends a request to the email address domain ( or, for instance) and checks if the address exists.

Email Domain Type and Quality Verification

In addition to the high-quality email domains on the market are those that are less trustworthy. It all has to do with how hard it is to open an account using them. For instance, while sounds reputable, it is free and thus concerningly easy for suspicious individuals to create their own gmail accounts.

Other providers have more stringent verification processes, such as SMS verification, which makes them more secure. Plus, quality verifications can be enhanced through domain checking websites as well as by ascertaining the email address’s age. While there are exceptions to this rule, such as when established email addresses have been involved in a data breach (more on this a little later), newer addresses tend to be less trustworthy than their more mature counterparts.

Email Address and Social Media Lookup

One of the most powerful ways to check the validity of an email address these days is to see if it has been used to sign up to any social media platforms. Also known as social media profiling, this process checks if the address is used by someone on LinkedIn, Instagram or Facebook, among others.

This is because a good social media lookup tool will also provide information about the person’s name, location, workplace and bio – all information that would take a tremendous amount of time to collect manually, especially if you need to do this for a long list of people.

Email Address Found on Data Breaches?

A good tool can compare the address to those found on data breaches. Finding it in one of those breaches helps provide an idea of how old the email address is, and how regularly it was used, but it may hint at illicit use if a fraudster took control of it.

Email Blacklists Check

Another way to check if fraudsters have already used that email address is to look for it on public spam blacklists. If someone’s registering with a known spammer address, you might want to block them or verify their other details manually, as the account holder might not have control over the mailbox anymore (or worse, it could be a malicious address).

Email Address Quality Evaluation

Finally, an interesting data point that can be hard to measure: How likely is it that the email address was created by a real user vs a bot or fraudster, both of whom need to work fast. This has to do with the quality of the email name itself.

Using string analysis, a good email profiling tool should be able to see if the email address looks genuine, or if it’s just been generated automatically. For instance, a large volume of numbers or special characters can be suspicious, as can differences between the name in the handle and that in the account.
