Process of Email Validation

Email Address Syntax Check:

This removes improperly formatted email addresses, according to IETF standards.

Domain/MX Records Check:

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

Role-Based Account Detection:

Email sends to role-based accounts such as postmaster@, info@, sales@, admin@, etc., can negatively impact your deliverability and even put you in denylist with some ISPs. This process detects and flags such addresses.

Disposable Email Address (DEA) Detection:

Throwaway/disposable emails, or “junk collector” emails, are detected and processed appropriately. These are temporarily created emails and used for signup forms or bypass login forms requiring a valid email address.

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.

Final Verification:

This phase performs deep-level extended SMTP verifications on each email address. The software will ping the emails to check mailbox existence without sending an actual email to the inbox.
