How does DeBounce validate emails to clean your list?


By a mix of validation methods and proprietary algorithms depending on the internal database, the validity of an email address can be found out.

Any invalid addresses are filtered out at the end of the list validation process, leaving a clean, fully deliverable email list ready for marketing and business requirements. We have explained in depth below how the process of email validation works.

Syntax Search for Email Addresses: This eliminates incorrectly formatted email addresses in compliance with IETF guidelines.

Domain/MX Records Check: This scans the email address’s DNS entries. It marks the corresponding email address as invalid if an MX entry is missing or finds the domain invalid.

Detection of role-based accounts: Email sent to role-based mail such as admin@, postmaster@, sales@, info@, admin@, etc., can have a detrimental effect on your deliverability, and certain ISPs can even blacklist you. This process identifies specific addresses and flags them.

Detection of Disposable Email Address: Throwaway or disposable email addresses are identified and processed correctly. Usually, these are used for signup forms or to bypass login forms that need an email address.

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

Checking DNSBLs and URI DNSBLs for blacklisting: A DNSBL is a list of IP addresses frequently used for spam. A URI DNSBL is a DNSBL that lists domain names that have been discovered in spam email messages but have not usually been discovered inside legitimate messages.

In the method, email addresses and IP addresses are tested to trap spam networks against known DNSBLs and URI DNSBLs.

Final verification: On each email address, this phase conducts deep-level extended SMTP verifications. Without submitting an individual email to the inbox, the emails would be pinged for mailbox presence.
