  • Remove or Isolate Duplicates

  • Email Network Information

    Append additional information learned about the email during the verification process.

  • Identify Free Mail Hosts

    Append a column indicating free mail hosts (i.e: gmail.com, yahoo.com).

  • Identify Role Accounts

    Append a column indicating role accounts (i.e: support@domain.com, info@domain.com).

  • Identify address

    Append a column indicating the address portion of the email. Generally this is anything before the @ sign. If this address includes an email alias, the alias will not be returned as part of this field.

  • Identify alias

    Append a column showing the alias portion of an email address. If an address contains an alias such as "david+test1@site.com" the alias portion is returned, otherwise this column is empty.

  • Identify host

    Append a column showing the host portion of the email address. Generally this is everything after the @ sign.

  • Identify subdomain

    Append a column to show the email host's subdomain if applicable. For example, if host was site.example.com, the subdomain would show a response of "site".

  • Identify domain

    Append a column to show the email host's domain name. This does not include any subdomain, if applicable, and does not include the TLD or top level domain portion. If the host was site.example.com, the domain would be "example".

  • Identify TLD

    Append a column to show the TLD or top level domain of the email host. If the host was "site.example.com", the TLD is "com".

  • Identify FQDN

    Append a column to show the FQDN or "Fully Qualified Domain Name". This is the portion of the host that you use to query DNS information. In most cases this will be the same as the host, however if a subdomain was included this will be removed from the FQDN. For example, if the host was "zone-1.zone-2.site.example.com", the FQDN would be "example.com".

  • Identify network

    Append a column to show the FQDN (Fully Qualified Domain Name) of the primary MX record. This is an attempt to determine the ISP hosting the email at a particular address and is useful for grouping addresses together by provider.

  • Identify valid DNS records

    Append a column to show whether one or more DNS records exists for this host.

  • Identify MX records

    Append a column to show whether this host has one or more MX records defined in its DNS records.

  • Identify reachable SMTP server

    Append a column to show whether NeverBounce was able to connect to a remote mail server identified by the host's MX records.

  • Identify Bad Syntax

    Append a column identify whether emails within a list contain bad syntax. Examples of syntax errors include spaces ( joe. smith@example.com) missing domains (joe.smith@example).
