Quantity is not quality. You have undoubtedly heard that phrase somewhere, but you may never have related it to your email marketing strategy.

Email is one of the most powerful marketing tools with a high ROI – especially considering that running an email marketing campaign costs almost nothing.

But having a massive email list does not mean success. On the contrary, there is no point in having a thousand addresses if half of them are not valid email addresses, which can be read by a real person.

That's what an email validation tool, like TheChecker, helps you.

Email Validation: what do you need to know?

The evolution of digital marketing is undeniable. New tools and communication channels have emerged in droves to make the interactions we make increasingly personal.

Not only that: today, we can also count on an almost infinite amount of data. This information serves to understand consumer behavior trends and make our campaigns more assertive.

But even with all that, you will still hear from any digital marketer: email is king.

The use of email continues to grow worldwide. According to Statista, adherence to this communication tool increases from 2% to 3% each year, which means that we will have more than 4.4 billion active emails worldwide by 2024.

It is an audience that cannot be ignored.

Beyond that, email democratizes your campaigns. It allows you to reach people outside your geographic reach and who have never even heard of your brand - that's why it's such a valuable tool.

But its importance is linked to the quality of the addresses that you gather in the mailing.

According to SendGrid, 20% of emails never reach their recipients, resulting in lost money and time. But why does this happen?

The creation of an email is not linked to each person's ID. Think about your own experience: you've probably had more than email in your life. You perhaps also no longer use these accounts.

It happens to everyone. And it is essential that you eliminate those addresses that are no longer used - in addition to those that do not exist - to clean and add more quality to your list.

In short, email validation is what allows you to know if your base addresses are real, and if there is a person behind each one.

TheChecker: the email validation tool you need

You may wonder now how it works.

The truth is that the concept of email validation is simple, but how it is done is not so.

The email server you use already has an internal validation mechanism, which checks if the address syntax (the way it was written) is correct and sends you a message when an email is sent back.

Another way of validation is to use JavaScript code in the browser. In addition to being complicated, this option would not work for massive email marketing campaigns, which send a high number of messages simultaneously.

The email validation tools, like TheChecker, were built to extend that power and deliver you really useful software.

TheChecker uses advanced algorithms and various tests to look beyond the syntax and deliver a concrete answer about the validity of an address. It works like an x-ray, which looks beyond appearances to identify real emails.

To check if an email is valid, our tool goes through the following check steps:

1. The email syntax;

2. If the domain exists and if the rules for receiving it are being followed

3. Unlikely names;

4. MX records, necessary for sending the email;

5. If the email is not a catch-all type;

6. SMTP authentication, which tells you if the email is really used.

That is the basic. Now, let’s take a look at how each step works.

1. Checking Email Syntax

You probably check grammar when writing an email marketing campaign, right? The email addresses do not need to follow grammar, but there are some other rules that they must follow for an email to be sent.

The syntax check looks for the following errors in an address:

  • Number of characters: the user's name (any part that comes before @) must not exceed 64 characters;
  • Standardization of elements: every email address must have the user's name, at sign and domain name;
  • Proper positioning: both the @ (at sign) and the. (dots) of the address must be in the correct place for the message to be sent;
  • Special characters: the use of special characters is allowed in the user's name, as long as they are not present at the beginning or at the end. They should also not appear at the end of the domain.

Also, the email validation tool checks for common typing errors, such as placing ; (semicolon) instead of @ (at sign) or, (commas) in place of. (dots).

2. Domain verification

The domain is what comes after the at sign and shows which website the address is linked. The tool also checks whether the domain is spelled correctly and whether it still exists.

For example, a domain such as @ joalheria.com may have ceased to exist because the jewelry store in question has stopped working and no longer exists. The store may also have moved to a new domain, making that address invalid.

Likewise, the domain must be spelled correctly and without the presence of special characters.

3. Checking unlikely names

It is also necessary to check if the email is not a randomly created address.

For example, the address 1e49cs1pb6@company.com contains a sequence of random characters, which can indicate your disability, along with other indications.

4. MX Records check

Mail Exchange (MX) records are the Domain Name System (DNS) records necessary for a message sent to an address to be received by it.

An MX record is an entry in the DNS for a domain, which specifies which server will handle email for that domain.

That is a slightly more complex step technically, but essential in email validation. The important thing is to know that, without the MX record, the email cannot reach its destination.

5. Catch-all email checking

Email validation also checks if the address is not a catch-all email.

Catch-all emails are those that receive all messages directed to a specific domain (even if the username was not created for that domain).

For example, you can send a message to hdash32@joalheria.com, which will go to contato@joalheria.com, a catch-all email created to "catch" all messages directed to the jewelry domain.

Catch-all emails can also be called accept-all and generally do not accept unwanted emails.

The validation tool identifies whether the email is of this type or not and notifies you to reduce your Bounce Rate.

You can still decide to send a campaign to this account - however, the chances of success at an address that does not have a personal profile defined to manage it are minimal.

6. SMTP authentication (ping test)

Another way to check if an email is valid is to send a message and ask for feedback from the user.

However, one of the main rules of email marketing is not to fill your recipients' boxes with messages - not to mention that this measure is not very efficient since not all users who are real people can respond.

For this, email validation uses SMTP authentication or ping testing.

For those more familiar with IT, ping is a tool used to identify connection errors. You can use the ping test to detect errors on the internet, for example.

When applied to email addresses, it checks for any obstacles in the path between the outgoing address (from where you send the emails) and the incoming address (from the recipient).

If the test arrives at the recipient and sends a reply, the tool will inform you that there are no problems and that it is an active email.

The test is also called SMTP authentication because this is the mechanism by which an ISP's customers are identified by the email server from which they intend to send the message.
