Final Verification: This phase performs deep-level extended SMTP verifications on each email address.

In the process, emails and IP addresses are checked against known DNSBLs and URI DNSBLs to trap spam networks. A URI DNSBL is a DNSBL that lists domain names that have been found in the body of spam email messages but generally have not been found inside legitimate messages.

Checking DNSBLs and URI DNSBLs for blacklisting: A DNS-based blackhole list (DNSBL) or Real-time Blackhole List (RBL) is a list of IP addresses often used for spamming.

Honeypot/ Spam Trap Detection: This detects spam seeds, BOTs, honeypots, blacklisted, or bogus email addresses by checking the addresses in the list against the known list of emails/domains, used for trapping spammers.

These are temporarily created emails and used for signup forms or bypass login forms requiring a valid email address.

Disposable Email Address (DEA) Detection: Throwaway/disposable emails, or “junk collector” emails, are detected and processed appropriately.

This process detects and flags such addresses.

Role-Based Account Detection: Email sends to role-based accounts such as, ,, , etc., can negatively impact your deliverability and even put you in denylist with some ISPs.

If a domain is found to be invalid, or an MX entry is missing, this process marks the corresponding email address as invalid.

Domain/MX Records Check: This verifies the DNS entries of an email address.

Email Address Syntax Check: This removes improperly formatted email addresses, according to IETF standards.

The legitimacy of an email address can be measured through a combination of validation techniques and – depending on the internal database – proprietary algorithms.Īt the end of the email validation process, any invalid addresses will be filtered out, leaving a clean, fully deliverable email list ready for marketing and business requirements.īelow, we’ve explained in detail just how the email validation process – essentially, a process of separating the wheat from the chaff – works.
