Best email finder 2020 – the ultimate comparison and test of the 11 most popular tools

13 April 2020 in B2B Marketing

It’s absolutely crucial to know your prospects’ valid e-mail addresses when you want to try outbound marketing / cold emails. When you Google “email finder” you can find plenty of different tools. All services claim that they will provide you verified emails of prospects for any domain you want.

In my case, I had scrapped a list of about 18,000 potential prospects (SaaS services with free trial or request demo option). I wanted to reach out to people responsible for sales or marketing at those companies and (best option) – get their name and surname so my cold e-mail would be more personalized.

By conducting random tests of various email finder tools found in some blog posts, I was completely surprised at the variety and sometimes strangeness of the results I had (or no results at all). Furthermore, there are many blog posts that collect lists of services of this type, but I have not found any reliable and independent article that comprehensively compared the quality of these tools. So, I decided to change it 🙂

How I made the assessment?

By writing this particular article I want to focus on the quality of the e-mails (Are they validated? How many emails have been found?). The second factor is the amount of additional useful data returned by each of the tools (name, surname, job position, LinkedIn profile). Those factors are simply most important to me. The third factor that I take most into account is price. The fourth, because of the large set of database, is an API access or at least possibility to upload CSV/Excel file with domains. The fifth, is access to some other helpful tools.

Other factors like chrome extension app, team option or general UI are included in my “general score”, but their “weight” is small in the final assessment.

To test the quality, I chose from my list 5 random very little known websites and 5 more famous brands present on the market for at least 3 years. Then I simply checked the results given by each tool. Simply as that, but as you see in a moment those results sometimes are unacceptable and nearly exclude the tool from practical usage.

1. super-toolkit.com review

A lot of different than e-mail finder tools are included (which I didn’t test) in their subscription plan. I focused on 2 of them which should be suitable for me need.

Email, phone & social media extractor from a list of websites

The first one is called “Email, phone & social media extractor from a list of websites”. Nice that they are trying to return a LinkedIn URL profile of the company (1 successful result), phone and many other data but when it comes to e-mail addresses the results are terrible. For one of the tested domain they returned me exactly an e-mail jane@example.com as a business e-mail!

Enrichment data software to find new leads (emails)

In the second tested tool you can upload a whole list of domains and a few minutes later download XLS with results – no API access. This time I received 40 results and many of them with lots of valuable data – job title, company name, company city, e-mail address, name, surname, and sometimes even personal e-mail address.

Unfortunately, they don’t have an e-mail validation tool. I had to download the CSV file and visited their competition to check if those e-mails are valid. Most of them – is not. After verification only 16 e-mails are valid but as many as 12 of them come from one domain.

What’s disturbing is that when I searched for e-mails for one tested domain they returned e-mail like jeff@yahoo.com (Yahoo!) as a business e-mail. In turn, it is unacceptable that I got another one result with a different domain than I tried to find (e.g. company domain I was looking is xyz.com and I received someone’s business e-mail with a totally different company domain).

Overall, excluding those strange results, super-toolkit.com found e-mails for only 3 different domains.

Results:

  • 12 e-mail addresses found; 3 domains
  • No clear data if any of them is valid

2. snovio.io review

Very good U. I found quickly nice option “Bulk domains search” (API is available separately!). I uploaded the XLS file and hoped to get results soon… Unfortunately, it didn’t work. After 10 minutes of waiting the result was as below:

snovio.io error

I didn’t give up, tried once again – this time I made file conversion from XLS to CSV and it worked! Very clear results – e-mails nicely prepared to launch a drip campaign directly from snovio.io service. The amount and quality of gathered e-mails were great + based on e-mails format they figured out the name and surname of persons. Very nice!

Then I checked their “find prospect” option – works similar way as e-mail finder but this time they filtered e-mails by job position – e.g. only those people whose job position contains “marketing” and “sales” phrase. Perfect for my purpose. It returns fewer results but more accurate to my needs.

snovio.io “find prospect” tool

When it comes to pricing, for finding e-mails + verification I used 21 credits. So, for checking 18.000 domains (finding + verification) snovio.io will charge me at least $199.

Additionally, they have some other tools available, Chrome Extension and e-mail drip campaign to run (not tested) which all this makes them a strong player on my tool list.

Results:

  • Snovio.io found 27 e-mails. Unfortunately, none of the e-mails was verified but I was able to verify all those e-mails directly from the list inside the snovio.io interface.
  • After verification 12 e-mails were marked as valid for 7 different domains, 5 as invalid and 10 as unverifiable. Very nice results.
  • In “find prospect” mode – 14 e-mails and 8 of them are marked as verified (e-mail + name + surname + job position + company name).

3. hunter.io review

Probably the most known email finder recommended in social media and some blog posts. Simple and clear UI, ability to send cold e-mails directly from the service. Nice working chrome extension and great API. Probably all you can expect from this type of tool is on board.

Similar to snovio.io service returns a lot of unconfirmed e-mail addresses. You can validate e-mail directly from the app by clicking a simple “check” sign or through the API. It costs you of course one additional credit.

There are probably two great things about this service which make it stands out significantly from competition.

  1. If hunter.io finds the e-mail address of a given person, additional data like name, surname, and LinkedIn account or job position are quite often presented too – no additional fees!
  2. As you will see in a moment, some services are just guessing e-mail addresses. But when Hunter.io finds someone’s e-mail they give you a source where that e-mail comes from! For people who manually check e-mails this is a great option for final verification of the prospect.
sample hunter.io e-mail search results with name, surname, LinkedIn profile, position (Founder), source where
e-mail was found + green “check” sign tells us that e-mail is validated . All this is also available through API.

Source of the e-mails

In case of one tested domain I came across interesting case study – hunter.io found three completely different emails than snovio.io. Both sites say that these e-mails are verified and valid BUT in the case of hunter.io I could visit the source websites where those e-mails were found. Of course, I checked those sources and actually e-mails were present on a given domain. This makes me trust hunter.io more as a data source.

I used more credits (34) but this is because they simply found more e-mails (so more e-mails to validate). To check all my database I would need at least 50.000 credits (399.00€) – much more expensive than snovio.io…

Results:

  • hunter.io found 58 email addresses
  • after verification of each unconfirmed e-mail I had about 35 emails form 8 different domains (8/10). Some of them with very valuable additional data (LinkedIn, job position, name, surname).

4. mails.wtf review

This tool requires to enter both name, surname and website URL of the domain to find e-mails. So, it’s not tailored for my requirements but anyway, I gave it a try and it seems that it simply doesn’t work at all. Or they had some technical problems – I don’t know.

Whatever I try to find (I tried various combinations of names, domains) – the are no results. Constantly “searching”, as visible on screen below. So I simply couldn’t make any review.

mails.wtf error

5. skrapp.io review

If I correctly interpret the results obtained by this website, they stand out from the competition in the way of collecting and processing data. Skrapp.io results comparing to the competition are strange – they found 194 e-mails! What’s even more surprising, all those e-mails come from just 3 domains and next to emails we have full details about the position, name, surname of each person. For the other 7 tested domains they didn’t find any results.

I added all those prospects to the private list inside the skrapp.io app. Thankfully e-mails are automatically verified. They provide a verifier along with the email finder (no additional costs). And the results here are not so impressive. Most of e-mails are fake.

skrapp.io – most of e-mails are fake, but…

Is their approach clever?

I may be wrong but I checked the company profiles on LinkedIn and compared it to skrapp.io returned e-mail lists. I think the way they work is:

  1. Find LinkedIn company profile based on domain URL
  2. Scrape all people associated with the company
  3. Guess their e-mails by popular scheme e.g. first name letter + surname + @ + company name . com
  4. Verify if e-mails exists

I have a problem with how to evaluate the service because they are actually (probably!) just guessing e-mails. However, remember that they provide a verifier along with the email finder for free. So it would be very reasonable to:

  • upload all your domains
  • run search and get all prospect names with the job position you search
  • add those prospects to the skrapp.io list (you pay only for added prospects to the list)
  • exclude e-mails that are associated with “catch-all” domains (unverifiable if they really exists).
  • download only verified e-mails

There won’t be many results, as they “search” quality is rather poor (4/10). Anyhow, this way for the relatively low price we can get e-mails + name + surname + job position. If I am making the proper assumption that those data come from LinkedIn, then they are very reliable and trustworthy. Those domains with no results we can check with other tools!

Results:

  • skrapp.io found 194 e-mails, just from 4 domains – most of them are fake.
  • after verification only about ~20 are valid BUT with reliable data and for a low price.

6. seamless.ai review

This is the first time I have seen such a convoluted registration form. Three steps. I had to type my physical address, how many employees I have, how many people work in marketing at my company and many others. If that wasn’t enough, in the end, I had to enter my phone number and enter the SMS code.

This particular tool allows you to search prospects; it’s not specifically an e-mail finder tool but rather to find specific people in specific departments, positions, cities and so on. I entered all 10 tested domains and received about 200 records with ability to check e-mail, phone, business phone, Twitter account, LinkedIn account and so on. I need to admin that they provided A LOT of information about each prospect and those information look credible.

A few “minor” flaws

Unfortunately, they don’t have an API (or I just can’t find it). There is no place to upload the domain list. There is no tool to validate e-mails. What’s worst – I can download only selected prospects. When you search for e-mails you need to enter a company name or domain name, then a list of prospects (name, surname, job position) are presented and you need to manually “check” which prospect details you want to get. In the case of 200 records it’s a lot of manual work, a lot of clicks because there is no button “check e-mails for all 200 prospects”. Some records don’t have an e-mail at all…

It would be great to simply download all 200 prospects, then sort by e-mail and filter those with validated e-mails (even with different tools). That’s why I can’t make a full test and can’t say how much of those 200 prospects are valuable. But I have to admit that they found contacts for one of the tested domains, to which no one had ever found contact before in my test.

Not sure, but I think they work the same way as skrapp.io (based on LinkedIn search). In my opinion this is nice, maybe even the best tool for manual prospecting (manual finding highly selected prospects) but not good if you plan any automation.

Results:

  • About 200 prospects but just from 4 different domains.
  • Can’t validate how much of them are valid e-mail addresses.

7. anyleads.com review

I hate services when I need to enter my credit card and then there is no option to remove it from my profile. I had to write them on the chat to do this.

Finding e-mails is one of 17 different tools. This is great of course but as usual, not quantity but quality is important. In the case of anyleads.com they just found 40 e-mails from 6 domains. What’s absolutely surprising those results are exactly the same as results from super-toolkit.com. Not only results but the name format of the downloaded XLS file, the name of the columns are exactly the same. It seems that those are exactly the same tools? They also marked someone’s personal business e-mail in the yahoo.com domain.

In summary, if you are looking for opinions about this service – scroll up and read super-toolkit review.

8. anymailfinder.com review

This is a particularly interesting tool as it charges you only for verified e-mails. With Anymail finder, 1,000 credits mean 1,000 verified emails. If you enter the domain name and e-mails are not validated then no credits are taken from your account.

Disadvantages of the tool? They don’t provide any additional data (name, surname or source of the e-mail where it comes from). The quality of e-mails comparing to competitors is rather good but lack of any additional data is frustrating. This would be absolutely perfect tool if they could provide e.g. job position or name/surname to some records.

Anyway, if you only care about the emails themselves this is absolutely the first tool you should use. It makes perfect sense to collect from them all validated e-mails (similarly to skrapp.io reviewed above but here we have better e-mail quality). For the ones they don’t find (or unverified), upload to other tools like Hunter, Snov.io which charge you for every e-mail – even unverified.

They have API but no Chrome Extension.

Results:  

  • They found 86 e-mails for 7 different domains which is a great result.
  • 43 of them are marked as validated from 4 different domains.

9. findthatlead.com review

Besides “email finder” findthatlead.com offers several other tools onboard – one of them is particularly interesting – “Social URL Search Find” – it allows you to find an email based on a social media profile URL. There is Chrome Extension and a tool which allows to create a new automated campaign based on gathered e-mails, e-mail verifier and so on.

When it comes to the quality of the e-mai finder. They found 99 e-mails from 7 different domains. Very good result. What’s noteworthy, for the first time I see that if they are guessing the email address (e.g. “catch-all” domain) this is clearly communicated on their site: “guessed address”. Big “plus” for that!

Some results are presented with additional data but not so many and as often as with hunter.io e-mail finder:

They don’t have an API but the “bulk domain search” option is available. Unfortunately, the price is rather high. A lot of emails are unverified and I used 25 credits for checking just 10 domains. To test all 18.000 will cost me about 300-400$ according to the current pricing.

Anyway, good quality of the email finder and nice amount of other “interplaying” tools makes it I included it on my list of the top 4 email finder tools.

Results:

  • 99 e-mails found from 7 different domains.
  • Most of them unvalidated – because of trial I couldn’t validate them all. Approximately about a half of them are invalid.

10. leadmine.net review

After the test of this service what surprised me that all email results were verified. 100% Confidence score. I don’t know if this is just coincidence or “standard”.

This is also probably just the second site I’m testing which presents sources of the e-mails (to be precise: number of the source pages). Too bad they do not present the URLs where they found e-mail addresses.

I need to mention that there is also a very nice “Lead search” tool which allows us to find prospects with e-mail + other data like name, surname, job position and so on. Quality slightly better than reviewed above snov.io – just a few e-mails from 4 domains but with very valuable additional pieces of information (name, surname, job position).

Results:

  • leadmine.net found 31 e-mails from 6 domains BUT all of them are validated. Pretty good result.

11. rocketreach.co review

Similarly to seamless.io it’s not strictly an e-mail finder tool, but I included it once again in my test because of decent search results. It allows search for prospects with very valuable data.

They found 209 prospects, which is nearly the same as seamless.ai result (reviewed above) BUT from 7 different domains. Can’t tell you how much prospects have proper e-mails – there is no way to check all data. You have to once again manually check each record from their database. As you see in the screen below, they are guessing e-mails and validating them (by the way, I don’t know why they just won’t remove invalid e-mails?).

Even if they didn’t find e-mails, there is nearly always a LinkedIn profile URL which is of course another way to contact people associated with the searched domain. Unlike seamless.ai, they have an extensive API.

Results:

  • Rocketreach.co found 209 prospects from 7 different domains.
  • Can’t tell you how many valid e-mails are out there. Probably most prospects are event without any e-mail but with some other helpful data like LinkedIn profile URL.

dropcontact.io, voilanorbert.com, findthat.email and many more

I decided to put to one paragraph all the tools which I couldn’t take a test. They may be useful for someone who has the name AND surname of the person AND additionally a company name/domain collected into one single file. Then each of those services returns e-mails.

In my case I don’t know my prospect names. Making some random tests I received nearly exactly the same results, so I assume that all those tools work the same way. They simply guessing e-mail addresses based on the name and surname (checking some popular schemas). Then validate the response from the domain server (SMTP, MX), and based on that response they can figure out if the e-mail is valid.

Anyway, I can’t say anything about the quality of the data at large scale – as I have only domain names I just couldn’t make the final test. As a tool to verify e-mail addresses some of those services, especially findthat.email might be worth checking.

So, which e-mail finder tool is the best?

It depends 🙂 Generally, hunter.io gives the best results and lots of other precious data but the best option depends on your needs and probably is to use a mix of tools.

I could divide my final assessment into 3 parts:

  1. If you need automation, large scale, and (best option) e-mails with names, surnames, job positions use hunter.io or (just right behind in order) findthatlead.com, leadmine.net “lead search” tool or snov.io “prospects search”. Skrapp.io may be an option too but the quality is rather poor (e.g. use it first, then exclude from your list all e-mails they found and go to another one tool like hunter.io).
  2. If you need large scale automation and only simple e-mails: go for anymailfinder.com first; then use hunter.io.
  3. If you don’t need automation and you can manually search for prospects I would start from rocketreach.co or seamless.ai, then leadmine.net, snov.io “prospect search” and for the rest e-mails that those tools didn’t found use hunter.io.

Lately I found another similar test of e-mail finder tools. It’s focused mainly on deliverability and has partly different results. I also encourage you to read.

Do you want me to include other tools in the test? Just write their names in the comment or e-mail me at chris (at) veltis.io

  1. […] It’s worth mentioning again that the objective of this study was to test these tools only on their deliverability rates. While making a decision to buy, you may have more criteria than just deliverability rate. But in my opinion, this is one of the most important one.
