Any email address using a blacklisted domain is discarded by the ISPs and Spam Filters, and having such in our Lists does untold damage as those entities add up the number of times one emails to them and mark you and us down as unsafe senders of emails. That damages the reputation of your “Sending” email address and the SendReach IP Addresses.
We therefore check against one of the largest and most reputable International Suppression Lists, and any matches are not accepted at the time of importing or subscribing.
Blacklisted email addresses are categorised depending on the reason for being listed, as below, and it is clear that any such email addresses cannot be mailed to without significant delivery issues and damage to the User ‘s Sending Domain and SendReach’s online reputation.
TRAP – Purpose built, Spam trap, or Honeypot email address, any email messages sent to this address are immediately considered unsolicited. Email address has known association of having direct ownership or control over the resources involved with the reception of a message leading to its submission to one or more DNSBL sites
MOLE – Collaborating, recipient submission based or via automated, domain level, anti spam solution evidence with no current, direct ownership of resources involved with the acquisition and processing of this email leading to its submission to a DNSBL. Yet historical evidence firmly establishes a relationship to one or more DNSBL site’s.
QUARANTINE – An email address in this category should be treated as non mailable and on 3 month probation as history has shown a great propensity that these once active traps gone dormant may become reactivated during this period.
SEED – Specifically defined as a, third party oversight email address used for general monitoring of company and company’s network resources used. Also this category includes, litigious address removal of litigators and collaborative anti spam activists historically known to purposely seed their email address(es) for the purpose of litigation.
NETWORK PROTECTED – Domains which have employed an outsourced, managed spam SaaS (software as a service) used as a front end, external firewall between your message and the domain of the email address. These domains and their recipients belonging to managed SMTP SaaS’s known to be highly collaborative, notifying and forwarding evidence to other leading industry DNSBL sites in real time.
INVALID – Defined as the inability to actually deliver an email message to intended recipients, receiving domain per RFC standards.
