Emails for Checks - Turns your cold mails - to hot leads.


We are a team that validates emails and phones using social networks for the past 3 years. Previously, we did it manually and it took from 3 weeks to a year, but at the moment it takes from us only 15 minutes to check 1 000 000 email addresses.

Our service will be useful to those who are working every day to increase conversion in email mailings and want to decrease bounce rate. We will also be useful to those who want to know who is behind that email or phone in order to save their time and money.

About email checkers

An email checker is a specific tool, which is designed to tell people whether some email address exists and how it behaves. Such tools mostly work online but also can be performed as downloadable apps for mobile phones, laptops, or PCs, yet still, they’d require the Internet connection to work.

Below, we consider how to check if an email is valid in bigger details.

What is an e-mail checker?

Using an email checker, it is possible to check email online using various approaches to logic and quality of the check. Some free email verifiers allow processing only one email at a time, whilst others offer bulk checks (but bulk checks are usually a paid option, which is mostly the way of monetizing such apps, including the payment, after the predetermined number of checks is used).

To verify email, a user copy-pastes a required address into the check field in the interface and presses the button of initiation. When we’re saying about the bulk check, checked emails are attached as a textual file to the working area. In that case, every separate email should correspond to one string of data, so as not to cause confusion of the tool when it will start to verify email.

Email verifying software has the logic in the core of it and we’re going to examine this logic now.

How an email checker works

Email verification procedure has several important steps to complete to make the email verification:

  1. It has to check if the email is real – so address should look like the one that has been created by a reasonable man ([email protected]), not like some robot or schizophrenic has created it (linq7vBBBoiql3‡[email protected]). The first one is likely to pass the check automatically, whilst the second is going to cause increased awareness. Also, the syntax is checked – mostly that there are characters before ‘@’, @ itself, characters after it, a dot, and the domain name – everything’s present where it should be.
  2. Next, a domain is defined and a sequence of ping commands is sent to it to define:

a) It exists.

b) It responds.

c) It does not respond all the same for all different queries, it gives reasonable and interpretable answers.

d Such email address exists on this server.

e) Quality of this e-mail and domain: whether they pass the email spam test, whether there are POP3 or IMAP clients, IPv4/IPv6/MX email verification is done.

  1. Then it is defined what those mail and domains are like: if created by fraudsters (if they are included in any blacklists accessible online or in the core of this Gmail checker), are they known to be bad or good ones, the confirmation is received do they participate in phishing, spam, fraud, connected to some bad guys – all is being checked from the publically available domains. Also, some tools when finding out does this email exist also lookup for the connection of this or that email to existing people, social media accounts, resumes online, and akin – to determine the existence of them in such a way. Based on entire found information, the final answer of email checkers is formed – within a fraction of a second.
  2. The result is provided on the user screen. It may have many options for displaying across various email checkers – as people working to code them are different. So, in some email tester, it may look like ‘Okay’ or “Not Okay”, whilst some other email checkers are going to feed you with tens of strings of information, completely disclosing the nature of the checked email. Thus, depending on your goals and needs when you’re going to check if the email is valid, make sure to find and test several tools to find out the best for your specific needs.

Email checker’s main users: disclosing ‘em

There is a tangible list of users:

  1. Companies, which main activity are email campaigns online, so they simply need to send thousands and millions of emails every month or even during one day. Without the results of the check if the email is valid, they cannot lower down their expenses and will not know whether there is anyone out there who is really reading those emails.
  2. Private persons, freelancers, owners of small and micro businesses – those who do not have a huge database of emails to send but who, nevertheless, wants to do the email validation in order to know the goodness of emails they’re holding because, in businesses as such, every or nearly every email is highly personalized. So it is better to do the email address verification upfront rather than to waste a fair share of your time composing a letter just to find out that it’s rejected shortly after being sent. Or not read, ever.
  3. Those businesses, which hold email campaigns on a periodical basis, during which they send thousands of letters monthly or quarterly, expecting the inflow of prospects and customers. They do want to check email, as, without the up-to-date database, their letters main be lost in vain, as they’re sent into the void.
  4. Those businesses, which do not hold promo campaigns periodically but who need to urgently or routinely contact their customers to bring them some information. Such a wave would have a low contact rate without being checked before by some email address checker.
  5. Those who operate any kind of CRM system, which sends emails in the background even without prior notification of managers or employees. This is done routinely but it is always better to construct some layer of intermediary check of available emails rather than to send just to everyone.

What are the benefits of using an email address checker?

  1. A bigger number of your letters reaches the destination.
  2. Being up-to-date: if you strongly rely on your database expecting for an outcome, refreshing it before a mailing campaign is a must.
  3. Having more details about the holders of emails. You may find the connected data: social networks’ profiles, other online presence – as an additional work that you can do not with the entire database but with verified pieces.
  4. Saving time, money, efforts – to everyone involved.

API for email checkers: what is it and why?

API is the Application Programming Interface, which allows third-party users to connect to the core functionality of some software and do some actions with it on an automated basis, without the need to use the graphical interface, which is mostly designed for retail users and a small number of operations.

We’ve seen many email checkers on the market over there and it seems like most part of them provides some API, which may be written in different programming languages. With such availability, it is possible to integrate the ability to make the email check into some third-party software, for instance, already mentioned CRM system, and all received emails will be checked automatically and independently – that’s a really nice approach. That also increases the value of any integrated system.

E-mail checker usage benefits: are there any

Yes, there are benefits. We’re highlighting them:

  1. Clearing up your database makes it possible to significantly reduce the bounce rate. It is told by many makers of email checkers that using their or similar tool, any database is being cleared at 10%-90%, so you’re reducing your cost, time, and efforts required to send a batch of emails.
  2. When it takes time in you to prepare the individual filling of the e-letters you send, having a purer database also significantly saves your time spent on the preparation.
  3. It is about your money. When it costs you, like, 100 bucks to send the batch of 10,000 letters, or when it costs you 2 dollars to send 100 letters after the batch is being purified – what will you choose?
  4. If you can connect to API and do the automated checks, your database will always stay pure.

Frequently Asked Issues about email checking tools

1. What is the bounce rate after the email address owner’s check?

A number of producers of email checkers tell that the bounce rate is lowered to 1%-5% after the verification – because some emails would still not be able to verify completely reliably. Still, without the verification, a database of 1 year old will be 70%-90% accurate, and the one of 5 years old will be only 10%-30% accurate, so without the check, the bounce rate will be tremendous.

2. Does the owner know his email has been verified?

No, as nothing is sent during the check on any email. All checks are done in the background, on the level of technical commands.
