E-mail marketer

I, like no one else, understand how nonexistent email addresses worsen the effect of email newsletters. Moreover, this is my area of responsibility. I convinced the head of the marketing department to subscribe to the Enterprise tariff from the emailс, and our newsletter immediately became more effective and targeted.

Check if Email is Valid

Are you in a leads group or a call center? Maybe you even work as a data broker, IT professional or in the email marketing space. Do you want to verify email addresses fast? Never forget that life is too short to be uncomfortable. Just check email online with the software. So, if you are tired and bored of checking email addresses one by one, you should take a look at the Email Checker. Moreover, it will help you organize and clean your contact list, thus increasing the efficiency of your email marketing campaign. Email validation will also help you protect your email sender score.

A recent study led by ReturnPath shows that in 83% of cases, low email sender reputation is responsible for emails not reaching their intended recipient. If you want to protect your email score, you have to regularly check your database to ensure that all the addresses in it are still in good use.

So, how to check if the email is valid? Let us explain the whole process of confirming email addresses. It is a simple gadget to verify if an email address exists. You can use it for free. In addition, it’s easy to use. You just need to write the email address and push the check button. And then the email verification tool tells you if the email address is real or not. Some series of checks will be executed on the e-mail address but no actual e-mail won’t be sent.

How does email validator work?

Email Checker actually connects to the mail server over SMTP and simulates sending a message and checks whether the mailbox exists or not. In some cases, the result of this email verification process might not be so accurate because some mail servers do not co-operate in the process of analysis.

In order to check if an email is valid or not, our technology connects to mailboxes through “mailbox pinging”. For people who are familiar with computer networking, pinging represents a crucial tool for understanding problems with the connection. Mailbox pinging works in a similar way to network pinging, so in that, it uses a “beginning computer” and an “end computer” (the email server). And this is the similarities stop point.

Main steps to test if an email is valid or not:

  1. Check whether the address exists or not.
  2. Optionally checker receive the input file.
  3. Then API checks validation.
  4. The next point to check on entry into the open list of one-time email.
  5. After it checks on the presence of the correct MX records.

Afterward, some processes start at the same time:

  1. Find SMTP server responsible for the e-mail address, and tries to establish an SMTP connection; If it acquires the connection it means that e-mail address exists.
  2. Check if the e-mail address is catch-all; Catch-all - a mail server function that allows you to redirect emails addressed to non-existent users to a specific email address. Example: If [email protected] is set as a catch-all address for the domain, any email sent to an unknown/non-existent mailbox in this domain will be redirected to [email protected] If the catch-all function is disabled, then such messages will be rejected by the mail server and returned to the sender.
  3. Check if the email address is registered on is a platform that allows you to build a website with your special needs and wishes. You can start an online store, blog, portfolio, business site or everything you can imagine. So, if an email address is registered on it gives more chances that email is available.
  4. Check if there is a user with this email address on; In short, GitHub is a web service that hosts billions of lines of code, and every day millions of programmers from all over the world come together to jointly develop open source IT projects. So, in other words, it is a software development platform based on the Git version control system. This monitoring helps us more clearly to be sure of verifying your email address.
  5. In addition, we check whether it is profiled with this email address on LinkedIn. This social network is intended for professional communication, not for entertainment. It is convenient for HR managers to find professionals to recruit and for future employees to keep abreast of news related to their professional issues. Business pages of companies, with articles and news, thematic communication, joint solution of complex issues - all these are options for using this portal. All these additional checks ensure us of the correctness of the answer we give to you.

After all, this operation email validation is over and the program gives you a rating of this email address. Rating more than 60% means that email is validated an email exists.

Is there an API for developers?

In general, Application Programming Interface - is a programming interface or an application creation interface. If we speak in a more accessible language, the API is ready-made code to simplify the life of the programmers. The API was created so that the programmers could actually facilitate the task of writing a particular application through the use of ready-made code (for example, functions). This is nothing new that the most efficient way to share service is to start with an API. Using simple API calls integrated the main requests on Email Checker can be made everywhere you need.
