How Does Email Verification Work?
Every email address is analyzed systematically with the help of different factors to verify this.
Let’s learn how the email verification procedure works.
Every email address follows a specific syntax standardized by the IETF, standing for Internet Engineering Task Force and RFC (Request for Comments). Email verifiers are capable of identifying email addresses that do not correspond with the standards. Besides, the verifiers remove these from the mailing list.
It generally checks:
The email prefix refers to the sequence of letters, numbers, & symbols before the “@” sign.
Email domain, i.e., email service provider’s name, which is available after the “@” sign. For instance, gmail.com.
An instance of a wrong email address syntax is xyz#123..@exampel.co.
Address Name Detection:
Hence, it is necessary to detect & flag email names that are suspicious or role-based because they affect deliverability because of blacklisting. Instances of a few of those email names are info@, admin@, email@example.com, etc.
DEA or disposable email addresses are identified & removed by DEA detection. Generally, people for subscriptions & sign-ups, use these temporarily to avoid spam emails.
Spam Trap Detection:
Spam traps can be disguised as email addresses. When you send email marketing campaigns to such addresses, these will get a spam mark. It affects the sender’s fame. If you want to prevent it from happening, use email verifiers which can remove spam traps from the email list.
DNSBL & URI DNSBL Check:
When you use an email checker, you can find this running your email via a DNSBL (DNS-based black hole list) and URI (Uniform Resource Identifier). You should know that the DNS-based black hole list contains IP addresses used in spamming, whereas the other one contains domain names in spam email bodies.
MX Record Lookup:
It is possible to check an email address’s MX records to identify invalid domains and verify them. MX records refer to the resource records within the DNS. This system helps to clarify which mail server will accept emails from a domain and which don’t. Once the verifier is able to detect an invalid domain, it will remove that specific email address from the email list.
Active Mailbox Check:
With the help of an email verifier, it is possible to send a ping request to the server of an email address to verify if it is active. As soon as the request is received & responded to, it will recognize the mailbox as active and authentic.
