Data Assurance Program

One-time cleanings isn’t enough!

Email data is constantly changing - what’s clean today could be a risk tomorrow. Spam traps, dormant accounts, and parked resources can appear overnight, putting your sender reputation and deliverability at risk. Read More.

Protect Your email Reputation daily. A one-time email cleaning or occasional list maintenance isn’t enough to keep your emails safe and effective. Without daily cleaning and monitoring, your email list can quickly become outdated, leading to:

Spam trap hits that damage your sender reputation Blacklist risks from sending to compromised addresses Increased bounces from deactivated emails Wasted resources on invalid or low-quality contacts

Don’t let outdated data cost you!

Daily data assurance ensures ongoing protection by identifying and eliminating threats before they impact your campaigns.

Actively Protect your Sender Reputation

To combat this ever-changing environment, Impressionwise offers our Data Assurance Program, designed to actively assure and guard against a wide range of email-based threats while protecting your online reputation daily with industry-leading daily reporting and results.

Pristine and Recycled Spam Traps

Removal of dedicated and repurposed email spam traps causing poor deliverability.

Learn More

Pristine Spam Traps . Email addresses that have never provided explicit permission to receive communications from an email marketer are flagged as unauthorized recipients.

Any messages sent to these addresses are classified as unsolicited and may result in the sender being reported to one or more blacklist sites.

Recycled Spam Traps . Email addresses that were once previously owned by a user but have since been abandoned or closed can later be reactivated and monitored.

These reactivated addresses, often referred to as recycled spam traps, are used to identify senders who continue to email inactive or unengaged recipients.

While primarily intended to identify and block spammers, they can also flag email marketers who fail to maintain clean and engaged contact lists, potentially impacting sender reputation and deliverability.

Catch-All Identification

Designed to identify risky and catch-all email addresses.

Learn More

The diverse behaviors of catch-all or accept-all email servers present challenges including:

Varied Server Responses . Different servers handle verification requests uniquely, making it difficult to confirm the legitimacy of catch-all email addresses.

This inconsistency can lead to unreliable results and complicate email validation efforts.

Limited Verification Attempts . Many servers impose restrictions on the number of verification attempts allowed, which poses a challenge for bulk email verification.

Exceeding these limits can result in temporary blocks or incomplete validations.

Delayed Bounces . Catch-all servers often accept all incoming emails initially but later reject invalid or undesirable addresses.

Key risks impacting your email outreach and sender reputation:

Elevated Bounce Rates . Catch-all emails can lead to increased bounce rates, causing several issues:

Unexpected Bounces. These addresses accept all incoming messages, resulting in unpredictable bounce occurrences that harm sender reputation.

Mailbox Overload. Catch-all mailboxes often surpass storage limits, leading to additional email delivery failures.

Lower Engagement. Messages sent to catch-all addresses may not be checked, which leads to reduced engagement and response rates.

Exposure to Spam and Blacklisting . Catch-all emails can heighten the risk of spam and blacklisting issues:

Spam Traps. Certain catch-all addresses may be used as spam traps, damaging your sender score and reputation.

Blacklisting Risks. Continual delivery attempts to invalid addresses can result in blacklisting by Email Service Providers (ESPs), further harming your email deliverability.

Increased Security Risks . Catch-all emails may expose businesses to security vulnerabilities, such as phishing attacks, putting sensitive data and systems at risk of compromise.

Impressionwise ensures accuracy of your email campaigns, helping to optimize deliverability and engagement.

Dedicated Honeypots and Contributing Moles

Removal of dedicated and collaborative antispam system traps or individuals.

Learn More

Honeypots . These are email addresses intentionally created and distributed across websites, forums, and other online spaces, designed to be harvested by spammers.

These decoy addresses, often maintained by anti-spam organizations, do not belong to real users and are used to monitor and identify spam activity.

Contributing Moles . This form of feeder email refers to collaborating recipient submissions, domain-level monitors, or individuals who actively contribute to anti-spam solutions.

While they may not have direct ownership of the resources involved, historical evidence often links them to blacklist sites, posing a risk to your sending reputation.

Parked Resources . Leverage our insights to avoid sending email traffic to millions of unused or parked website domains.

These domains are typically not configured for legitimate email use, and any emails sent to their recipients (e.g., catch-all or role-based accounts) are inherently invalid, increasing the likelihood of being flagged as spam.

Our expertise ensures your outreach avoids these forms of hidden traps.

Dormant-Disabled Accounts

Identification of Hotmail, AOL, Yahoo and Gmail internal anti-spam honeypots and disabled accounts.

Learn More

Our service includes detection of popular webmail honeypots from major providers such as Hotmail, AOL, MSN, Yahoo, Gmail, and other top email services. These honeypots are part of internal network defense systems designed to monitor engagement levels.

The number of these honeypots that marketers send to is a key metric that these providers use, alongside bounce rates and complaint levels, to determine whether your email will be delivered to the inbox or flagged as spam.

By identifying and avoiding these traps, we help ensure your emails have the best chance of reaching your recipients.

Third-Party Oversight Seeds

Identification of highly litigious and collaborative antispam sinkholes and activists.

Learn More

These form of email addresses are often added to lists, sometimes without the sender's knowledge, and seeded across various locations online. These addresses may be hidden on websites or submitted through unsubscribe forms.

Our services specifically include the identification and removal of highly litigious and collaborative anti-spam activists, ensuring compliance and reducing potential risks to your organization.

Toxic Domains

Detection of known companies and individuals recognized as consistent complainers.

Learn More

These are individuals or entities widely recognized within the industry as "complainers" or "screamers." They have explicitly stated that they do not wish to receive any form of unsolicited commercial email from any source.

Engaging with these recipients can significantly harm your sender reputation, as they are highly likely to report unwanted emails, potentially leading to deliverability issues or blacklisting.

Email Verification

Confirmation of email validation per RFC acceptance.

Learn More

Domain Validation . Our Domain Health Check performs comprehensive domain, email, and network performance tests to ensure all domains within your list are online and operating optimally.

This process verifies that receiving MTA’s server responds consistently and correctly, supporting seamless and reliable email delivery.

Group or Role Accounts

Detection of low engagement, system mailboxes that do not belong to an individual.

Learn More

A role account is an email address associated with a specific office, position, group, or task, rather than an individual.

These accounts are typically used for general inquiries or departmental communication and can be categorized as either technical or non-technical.

Common examples include postmaster@, abuse@, sales@, support@, info@, legal@, and inquiries@.

Understanding and managing role accounts is crucial for maintaining effective engagement and email deliverability.

Typo and Fake Emails

Detection of popular typo domains repurposed as honeypots or traps.

Learn More

These are spam traps associated with domains intentionally designed to resemble common domain names, such as "yaaho.com" or "ynail.com."

Emails sent to these addresses are often flagged as unsolicited and may result in the sender being reported to one or more blacklist sites.

Ensuring accurate email address collection and validation is critical to avoid these traps and protect your sender reputation.

Disposable Email Accounts

Identification of purpose-built, disposable email addresses with minimal response expectation.

Learn More

In some cases, an email user may need to provide their address to a website but lacks confidence that the site owner will not misuse it for sending unsolicited messages.

One solution to mitigate this risk is to use a disposable email address—an address that can be deactivated or abandoned after use, which forwards emails to the user’s real account.

Disposable email accounts enable users to complete sign-up and verification processes without exposing their primary email to potential spam, providing an added layer of privacy and protection.

Threat Keys

Removal of ISP, system or non-human generated email monitoring addresses.

Learn More

System-generated email addresses are randomly created using unique phrases or combinations of words, designed to appear distinct and bypass automated email filters.

These addresses are typically used to circumvent detection by spam filters.

To counter this, advanced filtering techniques are employed to detect and block offensive language, suspicious phrases, and unnatural email addresses, such as "1e49cs1pb6@company.com," ensuring a higher level of security and accuracy in email validation.

Email Blackhole and Catch-all Verification

Emails designed to be silently discarded, never being viewed by a human.

Learn More

Blackhole Verification . Certain email domains are configured to silently discard incoming messages—often referred to as "blackholes".

In these cases, the messages are dropped without notifying the sender, meaning they never reach the intended recipient and are never viewed by a real person.

Catch-All Detection . Catch-All or Accept-All email addresses are associated with domains configured to accept all emails sent to the domain, regardless of the validity of the recipient address.

While these addresses return a valid status during verification, it can be impossible to determine their true deliverability without sending an actual email.

Such configurations are often designed to protect legitimate users by initially accepting messages, only to silently discard them or send bounce notifications afterward.

Detecting these scenarios helps to refine email lists, improve deliverability rates, and avoid unnecessary bounce issues.

Detecting these scenarios helps to refine email lists, improve deliverability rates, and avoid unnecessary bounce issues.

Active Assurance, How it Works.

Once enrolled, all FTP files submitted and/ or API requests processed through Impressionwise are systematically integrated into a dedicated master list within our automated re-cleaning environment.

Any new email addresses not already contained within the Data Assurance account list are immediately cleaned using your primary Threat Removal Service account, with results delivered via the same method used to submit the data (FTP file or API request) and the email address added to the Data Assurance account list.
Service credits are deducted from your primary cleaning account only for new addresses not already contained within the current Data Assurance account list.
These new emails are automatically added to the Data Assurance account list, ensuring ongoing, automated cleaning at scheduled intervals.
At your selected interval (daily, weekly, monthly, or quarterly), the Data Assurance account list undergoes a full re-clean using the latest scanning technology.
Any changes in address status are compiled into a compressed file and delivered to your assigned FTP account.
You will also receive an automated email notification on each scheduled re-clean date, confirming detected changes and the availability of updated results.

The Data Assurance service is offered as a monthly subscription, requiring a 3-month minimum term, with auto-renewing periods thereafter. Ongoing assurance ensures your data is continuously cleansed and optimized - helping protect your sender reputation, improve deliverability, and reduce risks from traps and other harmful elements.
