Sender Reputation Threats
Pass
Email is not a Pristine Spam Trap or Honeypot.
An email address that has never given permission to an email marketer to send to
the address. Due to this any messages sent to this address are immediately
considered unsolicited leading to its submission to one or more DNSBL site's.
Honey pot addresses, which are email addresses created and spread across
websites, forums etc. waiting to be scraped or harvested by spammers. Some
organizations involved in fighting spam put specific email addresses on websites
that do not belong to real users and are decoys setup to monitor, collect and
catch spammers.
Pass
Email is not a Recycled Spam Trap or Mole.
Email addresses that once belonged to a user, but have since been abandoned or
closed. They are then reactivated at a later date and monitored to see who is
still emailing to that address. The idea behind these addresses is not only to
catch spammers but also to catch email marketers sending to unengaged
subscribers.
Pass
Email is not a Third-Party Oversight Seed.
Email address that is placed on a list, often secretly, that are created and
seeded in various places online. Typically they are hidden on websites or
sometimes dropped into unsubscribe forms. Typically used for general monitoring
of company's network resources used. Specifically, removal of highly litigious
and collaborative anti-spam activists.
Pass
Email is not a Typo, Bot, or Fake Email.
These are spam traps at domains that are very similar to common domains,
yaaho.com or ynail.com. Email messages sent to this address are potentially
considered unsolicited leading to its submission to one or more DNSBL site's.
Pass
Email is not hosted on a Parked Resource.
Possible sender reputation and deliverability impacts leading to possible
submission to one or more blacklist sites.
Email Deliverability
Pass
Email format is Valid.
Expected delivery impact due to email address is not properly formatted as per that emails domain policy or as per RFC.
Pass
MX records exist and replies for this domain.
Once first tiered DNE (do not email) elements (traps, moles, parked sites, etc.)
have been removed, the second greatest threat to your message deliverability and
eReputation is bounced addresses. Bounces come in many forms, some temporal
(mail box full, etc.) while others are permanent notifications (mailbox not
found, etc.) Even if you have a trap-free or “clean” list, sending to bounced
email addresses can cause great harm as most large ISPs (AOL, Yahoo, Gmail,
Hotmail, etc.) use this information in the form of a bounce rate to determine
whether or not to accept any future mail from your sending domain.
Pass
MX is not a Blackhole or Sinkhole.
Possible sender reputation issues. The MX DNS record points to a known Blackhole
or Sinkhole domain where incoming messages are silently discarded and never
viewed by a real person.
Pass
Email MTA does not accept any email addresses.
These addresses, commonly referred to as “Accept Alls”, contain a domain-wide
setting that accepts every single email received. It can be impossible to
determine the validity of the address. These types of email addresses are
commonly used in small businesses, and in some cases, the server will accept the
emails sent and then bounce it back to the sender. At Impressionwise, we have
the ability to determine these addresses are not riddled with spam traps or
other severe threats, so a potential bounce is your greatest threat when sending
to these recipients. If your list was obtained organically and you are confident
in the address's validity, these addresses may be used at your discretion.
Pass
Email is Verified, Deliverable.
Email address is not deliverable due to connecting MTA reported email address as unknown.
Pass
Domain exists
Domain does not exist.
Engagement Propensity
Pass
Email is not a Dormant Webmail Account.
Email addresses are not permanent. When there has been no login activity for a
long period of time, the recipient account is defined by the provider as
“inactive” and turned into a form of unknowing collaborator with no non-delivery
report (NDR) indicating “no such user” or “mailbox not found” being sent as a
response. Thus any email sent during this period of time before account
deactivation is assumed, in the collective, as spam and its email signature
mapped and used to block any email to other active recipient accounts within the
domain.
Pass
Email is not a Habitual Protestor.
No expected deliverability impact yet possible sender reputation issues via
lodged complaints to your ESP.
Pass
Email does not contain any known Threat Strings.
The email address contains threats that will negatively impact sender
reputation or deliverability.
Pass
Email is not a Role Account.
No expected sender reputation nor deliverability impact yet lower level of
engagement likely.
Pass
Email is not a Disposable Email Address.
An email user may sometimes need to give an address to a site without complete
assurance that the site owner will not use it for sending spam. One way to
mitigate the risk is to provide a disposable email address — an address which
the user can disable or abandon which forwards email to a real account. These
disposable account will allow the visitor to sign up and verify his registration
without exposing his primary email account to spam.
