However, there are several ways to check email addresses validity. We are going to introduce some of the most common practices to execute this task.

Why is an email checker important?

Keep email lists clean

When your contact list is not clean, your messages are sent to many fake email addresses, which means they are not even going to arrive at real mailboxes. This will have a negative impact on all the messages you send.

But, a mail checker can remove these bad registrations, keeping your reputation safe and sound. 

Reduce hard bounces

Your emails can bounce for several reasons. For instance, misspelled addresses or emails that are no longer active are some of them. These situations are called hard bounces.

If you have to deal with many corporate emails, it is extremely important to check them before they enter your database. They change all the time and can become inactive at any moment.

That’s why you must check email validity frequently. A mail checker can even prevent this kind of invalid address from being added to your contact lists. If your hard bounce statistic is too high, maybe it’s time to give your lists a good cleaning.

Improves deliverability and reduce bounces

You must interpret the success of email marketing strategies based on the engagement your messages can generate. Measuring your success with the number of people you reach is a huge mistake.

This is true because looking only at a number can put you on the wrong track and paint a scenario that may not be related to reality. Always consider engagement as the most important factor in your marketing campaigns.

When you have a mail checker, it is easier to increase your deliverability rate, once you only send messages to active and responsive users, avoiding bounces and spam reports.

It can boost your results

As a consequence, the Return on Investment rate (ROI) can be optimized and boosted. You should often check email addresses validity to find these users that can give you the return you need, as well as identify the ones that don’t show any kind of interaction or interest.

Keep a high sender reputation

Having a high sender reputation is essential to keep your messages away from being marked as spam. It will also guarantee that your emails are going to be sent to your target audience.

Your reputation as a sender determines a sort of relevant factors, among them your deliverability and bounce rates. It may also be a relevant factor when reaching new people.

Besides that, a good sender reputation is important to avoid being blacklisted and to control bounce and spam report percentages. 

How does the Email Verifier work?

A mail checker is a tool used to analyze an email address and determine if it belongs to a real person or not. But how does it check email addresses validity? Is it effective and accurate? Is it safe? Let’s understand the way this tool works.

Request for Comments (RCFs)

You should know that valid email accounts have a certain pattern. The Internet Engineering Task Force (IETF) is responsible for creating such patterns and standards, which are found in emails too, and are called Request for Comments (RFCs).

Such patterns and standards determine what is the format of an email address, as well as the body of the email. They can even define how an email is transmitted from one device to another.

RFCs change over time and the tools you use to verify email addresses must be working according to them, which means you have to avoid obsolete systems.

The most current RFC receives the number 6531, and it deals with internationalized email addresses, where non-existent characters are used in the ASCII (American Standard Code for Information Interchange) table. 

In short, it means that other alphabets, such as Cyrillic, Greek, Japanese, and others, can be a part of an email address. 

Syntax check

A mail checker can analyze major RFCs for syntax validation of your email addresses, checking both the local part (basically everything that comes before the @ sign) and the domain (it identifies where the email box is hosted, and you can find it in the characters that come after the @ sign).

MX record check

An MX record specifies which servers that receive email messages for a specific domain. This feature checks if the email is actual, registered and the hosted domain. The MX record check is an important step to any email checker software.

Spamtrap removal
