Email Checker Steps : Ensuring Authenticity

Email Checker

1 - Syntax Control

Syntax validation is the first step in email verification. It involves ensuring that the electronic mail adheres to the standard format (name@domain.com), including the verification of special characters and the overall structure.

2 - Domain Name Verification

It is essential to check whether the email's domain name exists and is registered. This step helps eliminate fictitious or incorrect domains, strengthening the email’s validity.

3 - Catch-All Email Address Detection

Catch-all are those that receive all emails sent to a specific domain. Identifying these allows distinguishing generic emails from personal ones, thus improving the accuracy of the verification.

4 - MX Record Examination

MX records (Mail Exchange) are crucial for determining a server's ability to receive emails. Examining these records helps confirm if the destination server is correctly configured to receive emails.

5 - Sending a Ping to the SMTP Server

Email ping, although less common, involves sending a light signal to the address to verify its existence without sending a full message. This method can help confirm the activity and responsiveness of the email.

6 - Other Tests and Verifications

In addition to these methods, several other tests can be performed. These additional tests contribute to a more comprehensive evaluation of the email address's validity.

Email validation ensures that the addresses on your list are valid and active, reducing the risk of being marked as spam. By eliminating invalid addresses and avoiding spam traps, you improve your sender reputation and the deliverability of your promotions. This helps your emails reach the inbox rather than the spam folder.

Sender reputation is the score that an email service provider (ESP) assigns to an email sender based on their sending practices and recipient engagement. A positive reputation increases the chances of emails reaching the inbox, while a poor reputation can result in messages being flagged as spam or blocked. Key factors include bounce rates, spam complaints, sending volume, authentication methods (SPF, DKIM, DMARC), as well as the quality and relevance of the content. By using our email tester, you can remove invalid addresses, keep your list clean, and improve your sender reputation for better deliverability.
