Enterprise Email Verifier

Email Verification Rules Applied

• Valid format:

  Basic and first rule the email id must be in correct format of email@emailprovider.com

• Presence of MX Records:

  We check if there are MX records on the domain. If there aren't, the email address can't receive emails.

• Presence of SMTP Server:

  This check is successful if we are able to connect to the SMTP server (indicated in MX records).

• Accept-all Domain:

  We check if the server has a catch-all policy which accepts all the email addresses.

• Role-Based Account Detection:

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

• Disposable Email Address (DEA) Detection:

  Throwaway/disposable email addresses, or “junk collector” email addresses,” are detected and processed appropriately. These are usually used for signup forms or to bypass login forms which require a valid email address. We check if the email address has a domain name used for temporary email addresses.

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

• Final Verification:

  This phase performs deep-level extended SMTP verifications on each email address. The addresses will be pinged for mailbox existence without sending an actual email to the inbox.
