What is a Bulk Email Validation Service?

Bulk email list verification is the process of verifying an email addresses list is fully valid and deliverable.

This process involves an address-by-address analysis of each email on an uploaded list and is offered as hosted software.

How do email validation tools work?

You can measure if an email address is valid through a series of validation tools.

At the end of the email validation process, any invalid addresses will be filtered out, leaving a clean, fully deliverable email list ready for your email marketing campaign.

This is how the email validation tools work:

  1. Email Address Syntax Check: removes invalid email addresses format, according to IETF standards.
  2. Domain/MX Records Check: verifies the DNS entries of an email address, like invalid domains and missing MX records.
  3. Role-Based Account Detection: detects emails that have [email protected], [email protected], [email protected], [email protected], other, which can negatively impact your deliverability and make ISPs blacklist you.
  4. Disposable Email Address (DEA) Detection: detects disposable emails, emails that are temporarily created and used for signup forms or bypass login forms.
  5. Honeypot/ Spam Trap Detection: detects spam seeds, BOTs, honeypots, blacklisted, or fake email addresses.
  6. Checking DNSBLs and URI DNSBLs for blacklisting: checks emails and IP addresses against known DNSBLs and URI DNSBLs to trap spam networks. A URI DNSBL is a DNSBL that lists domain names associated with spam email content.
  7. Final Verification: performs deep-level extended SMTP verifications on each email address that checks mailbox existence without sending an actual email to the inbox.
