We have to discover e mail addresses for the launch in 2 weeks – about 400 ought to do.


No one likes to listen to that the subsequent week of their time might be spent researching, choosing, and verifying lots of of e-mail addresses. It’s boring sufficient to make you complacent, however any errors are pricey.

In different phrases, it’s one of many tedious marketing processes which all of us like to hate.

In any case, 400 emails are not any good in the event that they’re all blocked by spam filters.

I knew there needed to be a greater method than Googling the audience, so I examined 9 e-mail lookup instruments and managed to seek out one with 92% accuracy.

Not solely that, however I had a revelation as to why many of those instruments are worse than they first seem.

However sufficient about that – let’s get to the testing.

The check to seek out e-mail addresses

With no constant check there’s virtually no profit to making an attempt out these instruments in any respect – you possibly can’t decide one software higher than one other until it has the identical gauntlet to run.

So, to place these instruments via their paces I tasked them with to seek out e-mail addresses we already knew. That approach there’s no uncertainty as to how correct the instruments are.

The 5 individuals I used have been:

Justin’s e mail is personal however UG’s could be very public, and the opposite four have emails tied to their firm area, however with various levels of publicity. Ben, Bryan, and Ina all have Google outcomes pointing in the direction of their right work e mail handle, whereas Mike has his displayed in his LinkedIn bio.

5 e-mail lookup instruments examined

First up; sure, I do know that I promised 9 instruments within the title. I checked out 9 instruments, however four are extra suited to the “honorable mentions” part later within the submit, as they serve totally different functions than pure e-mail lookups.

Having stated that, the instruments I’ll be specializing in are:

  • Slik Prospector
  • RocketReach
  • Hunter
  • Clearbit Join
  • E mail Format

Let’s get began.

Slik Prospector

Slik Prospector is a Chrome extension which helps you to collect peoples’ e mail addresses by means of their LinkedIn profile. Simply click on the additional button Slik creates on their profile, and there you've the individual’s e-mail able to go.

Boasting a 95% deliverability price, I had excessive hopes for this software. It’s straightforward to make use of, has a number of glowing feedback (and virtually 800 upvotes on the time of writing) on ProductHunt, and may export the leads you discover to a CSV file.

You get 25 free verified e mail lookups when signing up (if one isn’t discovered then it doesn’t rely) and after that it begins at $30 per 30 days for an additional 300 credit per thirty days.

Check outcomes

Within the core 5 checks Slik did fairly properly, with an 80% deliverability price and 60% success price:

  • Justin – did not ship, however he doesn’t have an e-mail tackle tied to his firm’s area, so truthful sufficient
  • Ben – delivered a false e-mail (the area was right, however the format was flawed)
  • Bryan – success
  • Ina – success
  • Mike – success

The decision

Slik has affordable deliverability and a suitable e mail success fee. After double checking, it even managed to point out me that the e-mail we had for Ina Fried was incorrect (sorry about that Ina), so additional factors there.

Nevertheless, I can’t advocate it, each due to Ben’s false delivered e-mail, and the implications behind it.

Getting an incorrect e mail is predicted – you possibly can’t anticipate a device to magically clear up all the issues you throw at it – however the greater drawback right here is the shortage of consumer suggestions Slik provides.

If I didn’t already comprehend it, I might have no concept that the e-mail was false with out checking it myself, and if I used to be going to verify them myself, I’d in all probability have the identical success simply looking for the e-mail tackle with out utilizing a software to do it.

Not solely that, however as a result of there’s no indication as to which emails might be false, you’d need to double examine each e mail tackle. The failures make any successes out of the blue doubtable.

The false end result additionally makes little or no sense, and (to me) means that Slik doesn’t verify the emails it finds. In any case, Ben’s Course of Road e mail is publicly out there in Google – one seek for what number of outcomes return that e-mail would present Slik what the probably candidate is.

find email address - slik pricing

Now think about should you pay $30 and use these 300 credit to get collectively an inventory of journalists for, say, a current product launch. With Slik, each a type of emails could possibly be incorrect and I’d haven't any method of understanding it with out placing additional time in to manually examine them.

In truth, Ben did precisely that and used Slik to attempt to discover 40 emails earlier than the Course of Road launch. Not one was discovered.

For this reason I can’t advocate Slik to seek out e mail addresses. False emails aren’t an issue, however the failing to inform your customers that they might be incorrect negates any time they save through the use of it.


RocketReach is a web-based software which helps you to search a reputation, firm or LinkedIn profile URL to retrieve emails. It’s a useful midway level between instruments which discover e mail addresses from an organization’s area and people which seek for particular peoples’ emails.

RocketReach additionally provides you hyperlinks to your searched contact’s social media profiles.

find email address - rocketreach dashboard

Whereas it has a free plan, you’ll solely get three contact lookups per thirty days. After that, the pricing begins at $49 per thirty days for 170 lookups (which additionally nabs you 24/7 help). Larger plans additionally allow you to sync your findings with Salesforce and achieve full API entry.

Check outcomes

Because of the three lookup restrict solely Justin, Ben, and Mike have been analyzed:

  • Justin – succeeded, bringing in each UG’s common e-mail and three others related to Justin
  • Ben – failed, because the retrieved e mail was incorrect
  • Mike – succeeded, however didn’t discover his TechCrunch e-mail

The decision

RocketReach fared a bit higher than Slik, however solely as a result of it retrieves all the e-mail addresses it may well discover in your three lookups. The issue once more lies within the lack of consumer suggestions.

Like Slik, with out manually going by means of and verifying the e-mail addresses there’s no means of understanding if the e-mail you get is right or not. Because of this the software can't present worth by itself – all the things needs to be checked, which means extra work for the consumer.

Due to this I additionally really feel just like the pricing plans are somewhat restrictive. With none sort of verification (aside from manually checking every end result), RocketReach’s solely saving grace is the breadth of data it provides you for every lookup.

Having quick access to a contact’s social media accounts, together with delivering a number of e-mail addresses and the way straightforward it's to discover a contact make RocketReach a semi-viable candidate, however provided that you’re prepared to place within the additional time to confirm every handle your self.


Hunter (beforehand E-mail Hunter) is a web-based e mail lookup software with a Chrome plugin for fast use.

find email address - hunter search

The primary website allows you to search for a corporation area, and lists each e mail handle it may discover on that area – you possibly can’t seek for an individual with out figuring out the area.

It additionally supplies a “confidence rating” for every outcome, exhibits the webpages the handle was gathered from, and has a separate verification device to say how doubtless an e mail is to bounce. In any case, there’s no level in making an attempt to improve your clickthrough rate if the entire thing bounces to start with.

The free plan provides 150 “requests” per 30 days, however CSV exporting is locked into the paid plans. The paid plans begin at $39 per 30 days for 1,000 requests.

A “request” is counted as a website search which retrieves any outcomes (10 are proven at a time), with a brand new “request” used to see the subsequent 10 emails gathered from a search. A “request” can also be counted when utilizing the verification software on an e mail handle.

find email address - hunter verify

You can too bulk search or confirm emails, however doing so requires CSV exports, which means that it’s locked into the paid plans.

Check outcomes

Though Hunter appears to be designed extra for finishing up an e-mail lookup for a whole area, it handed the complete check with flying colours:

  • Justin – success, however didn’t retrieve his private e mail (understandably)
  • Ben – success, although the “widespread sample” for Course of Road’s emails doesn’t apply
  • Bryan – success, though a number of requests have been required to succeed in his e-mail
  • Ina – success, though a number of requests have been required to succeed in her e-mail
  • Mike – success, though a number of requests have been required to succeed in his e mail

The decision

Though I had to make use of a number of requests to seek out the outcomes for particular individuals, Hunter is implausible for performing an e-mail lookup (so long as you already know the goal area).

The important thing right here is the consumer suggestions it offers which Slik and RocketReach are so sorely missing.

find email address - hunter sources

It lets you see what sources it pulled the emails from in Google and provides an estimate of how possible the e-mail is to be right.

That is essential for an e-mail lookup device.

Somewhat than pulling the handle from seemingly nowhere, Hunter offers the knowledge you could decide whether or not or not it's essential to examine it your self. It provides you adequate info to take a calculated danger, slightly than making the choice for you.

Plus, for those who’re not sure of an e-mail, you need to use the verification device to get an extra sense of how legitimate the handle is, all with out leaving the location.

Not solely that, however the base outcomes appear to be extremely correct – Ben additionally used Hunter to check emails for the PR marketing campaign of our launch, however this time put 450 emails via the grinder.

find email address - hunter formula

Admittedly he needed to guess some emails utilizing the “most certainly” formulation Hunter generates when looking a website, however even with that solely 34 bounced.

That’s a 92% success fee with room to spare for those he guessed.

Briefly, even on the free plan, Hunter rocks.

Clearbit Join

Clearbit Connect is a free Gmail plugin which helps you to seek for 40 e-mail addresses per 30 days utilizing an organization’s area.

The primary benefit of Join is that you need to use it with out leaving Gmail – putting in it places a button on the prime of your Gmail interface which opens an overlay in which you'll be able to seek for e mail addresses. Then, in case you discover one you need to use, you simply need to click on on it to create a brand new message to that individual.

find email address - clearbit

Check outcomes

Join is extraordinarily straightforward to make use of, and has an inexpensive success price:

  • Justin – did not retrieve any emails, regardless of having Justin’s picture for UG’s search entry
  • Ben – success
  • Bryan – success
  • Ina – success
  • Mike – failed, as the e-mail retrieved was incorrect

The decision

While straightforward to make use of and fairly profitable, Clearbit Join falls prey to the identical lure that Slik and RocketReach endure from – a scarcity of seen verification.

Once more, even when extra e mail lookups are right than not, you haven't any method of figuring out for positive until you manually confirm them your self, which successfully neuters the comfort of getting it as a Gmail plugin.

find email address - clearbit connect ben b

Having stated that, the sheer comfort (and free nature) of Join makes it ideally suited for the odd e mail search in case you’re, say, in search of a selected writer to pitch at a weblog you need to visitor publish on.

E mail Format

Email Format is just like Hunter, in that it’s a web-based software which helps you to search an organization’s area for e-mail addresses. Format, nevertheless, focuses on discovering the almost certainly format for e-mail addresses on that area (eg, “”).

The design is primary, however every website e mail components is given a confidence rating and you may see the e-mail addresses it discovered for every website in a second tab. For $5 a month you may as well export your outcomes to an Excel file.

find email address - email format

Check outcomes

Regardless of being good in concept, E mail Format fared badly within the check:

  • Justin – failed to seek out the area
  • Ben – failed to seek out the area
  • Bryan – failed to seek out the area
  • Ina – failed to seek out the area
  • Mike – succeeded find Mike’s e mail, however obtained the area’s e-mail sample flawed

The decision

It’s good in principle, and provides some suggestions as to its findings, however the variety of domains it did not even acknowledge was the most important deal breaker out of all of the instruments to date.

E-mail Format’s larger plans could also be low cost, however no. Simply… simply no.

Honorable mentions

Earlier than I'm going forward and wrap up my findings, right here’s a few instruments I discovered which, while not becoming our concentrate on free instruments to seek out particular emails, could possibly be nice catches for various functions.

Clearbit Prospector

The older, extra skilled counterpart to Clearbit Join, Clearbit Prospector is a a lot bigger product designed to collect big numbers of emails directly, whether or not by manually looking for kinds of staff on a selected area (eg, “engineers at”) or by integrating with different packages.

find email address - clearbit prospector

The worth is just a little steep (beginning at $1k a month), however for large-scale e-mail lookups, Prospector might be value a glance.

Individuals Search

People Search by Workable is just like the primary instruments assessed earlier – it’s a Chrome extension which helps you to search somebody’s identify to see a profile which collects knowledge from LinkedIn, Twitter, Fb, and different sources.

It succeeded find the right e mail addresses for Ben, Ina, and Mike, however the free plan has a restrict of three searches per day and 10 most per 30 days. After that's has a “Recruiter license” for $300 per thirty days which has no restrict to the variety of searches.

find email address - people search

For this reason Individuals Search is down in honorable mentions – the device itself appears very helpful for getting a radical abstract of an individual, however is geared in the direction of recruiting functions moderately than purely discovering emails.

Qwilr Sherlock

Qwilr Sherlock is a extra primary software than the others on this listing, in that it’s extra designed to generate potential variations for an individual’s e-mail from their first identify, final identify, and area.

find email address - qwilr sherlock small

It’s a Chrome plugin that, by getting into an individual’s first identify, final identify, and their area, will copy an inventory of variations of their e-mail handle to your clipboard, which you'll be able to then paste some place else for verification.

By itself this wouldn’t be too helpful, however mixed with the subsequent device it’s much more viable…


Rapportive is a Gmail plugin which checks e mail addresses you enter, then shows profiles related to them.

Once more, by itself this wouldn’t be too helpful to seek out e mail addresses, however when mixed with Sherlock it checks all the variations and exhibits you any which might be linked to an present profile.

find email address - rapportive

It’s slightly extra work than simply wanting up a website with Hunter, however should you don’t need to depart Gmail (and don’t need to use Clearbit Join) it’s a reasonably efficient answer.

Discover 92% of e-mail addresses utilizing Hunter

Though a lot of the instruments above are helpful in a method or one other, the clear winner for performing small-mid scale e mail lookups is undoubtedly Hunter.

Should you hadn’t already guessed, the suggestions it provides is the killer.

For instance, nowhere in Slik’s app does it notify you what number of sources it retrieved the e-mail tackle from, what these sources are, what sort of verification the tackle has been put by means of, and even how doubtless emails to that tackle are to bounce.

Hunter, in the meantime, has a aggressive pricing plan, a beneficiant free plan, a 92% success price, and provides you all the info it is advisable to know to guage whether or not it's essential to examine the tackle your self.

A lot of the different apps take a danger with the emails they discover, then don’t inform you how massive that danger was. Because of this you’ll need to verify each e-mail they retrieve – when you’re looking for particular emails within the first place, likelihood is that they’re necessary sufficient to must be right.

However, should you’re informed than an e-mail is 30% sure and nonetheless use it, the one one at fault is your self for ignoring the danger.
