Do you know how Verification of Email Address Works? Email verification is a crucial tool for businesses sending mass emails since it evaluates whether a list of email addresses is authentic and deliverable. The technique is offered as hosted software and comprises an address-by-address analysis of each email on an uploaded list. A disposable email address is a one-time email address that expires after a set amount of time. When visiting blogs and websites that demand them to fill out marketing forms or subscribe to continue browsing, people create and utilize disposable emails to evade spammers and phishers. Emails sent to these addresses go undetected or are never delivered, harming their deliverability and reputation as senders.


How Verification of Email Address Work?

Real-Time Email Validation can be determined using a mixture of validation approaches and internal database proprietary algorithms. Any invalid addresses will be filtered out at the end of the list validation procedure, leaving a clean, completely deliverable email list ready for marketing and commercial needs. To validate an email address, it is methodically assessed using a range of variables.

Syntax Check:

The Internet Engineering Task Force has standardized the syntax for all email addresses. Email addresses that do not match these criteria are flagged and removed from the mailing list by an email validator. According to IETF guidelines, this removes badly formed email addresses.

DEA Detection:

DEA detection finds and removes disposable email addresses, which are frequently used by people for signups and subscriptions to avoid spam emails.

Spam Trap Detection:

Spam traps are email addresses disguised as fraud management solutions. They were developed by major Internet Service Providers in order to identify and block spammers. If email marketing campaigns are sent to these addresses, they will be classed as spam, negatively impacting their sender reputation. Email verifiers assist them in removing spam traps from their email list, preventing this from happening to them.


When an email is checked, it is run via a DNS-based blackhole list and a Uniform Resource Identifier (URI). DNSBL is a list of spamming IP addresses, whereas URI DNSBL is a list of domain names exclusively discovered in spam email bodies.

MX Record Lookup:

Identifies invalid domains by checking and verifying the MX records of an email address. Mail exchange records are Domain Name System resource records that specify which mail servers accept emails from a domain and which do not. When the validator detects an invalid domain, it removes that email address from the recipient’s address book.

Active Mailbox Check:

To ensure that an email address is active, an email verifier sends ping requests to the server. It considers the mailbox as authentic and operational once the request is received and responded to.

Honeypot Trap Detection:

This checks the addresses in the list against a known list of email domains used for catching spammers to detect spam seeds, BOTs, honeypots, blacklisted, or fraudulent email addresses.

Final Verification:

For each email address, this phase performs deep-level enhanced SMTP verifications. Without sending a real email to the inbox, the addresses will be ping for mailbox existence.
