Service Introduction FAQ’s

Email verification ensures every address in your list is valid, deliverable, and safe to send to.

Benefits:

• Prevents bounces and protects sender reputation
• Improves inbox placement and engagement rates
• Reduces wasted sending costs and campaign inefficiencies
• Maintains compliance with GDPR, CAN-SPAM, CCPA, and other regulations

A spam trap is an email address created by mailbox providers to detect senders using invalid, recycled, or low-quality addresses. Sending to a trap can:

• Severely damage your domain and IP reputation
• Trigger mailbox filtering or blocklisting
• Reduce inbox placement for all recipients
• Increase complaints and bounce rates

Types of spam traps:

1. Pristine traps – never used for communication; designed to catch spammers
2. Recycled traps – previously valid addresses that were abandoned and reused

We use a multi-layered predictive system to identify high-risk addresses before sending:

• Cross-referencing known trap databases
• Behavioral and engagement analysis (inactivity patterns, bounce history)
• Source validation to detect weak or suspicious acquisition channels
• Real-time predictive scoring to flag risky addresses

This ensures traps are safely suppressed or removed before they impact deliverability.

No. Basic verification only checks if an email address is syntactically correct and whether the mailbox exists. It cannot detect spam traps, recycled addresses, bots, or decayed inboxes.

Impressionwise goes further:

• Behavioral risk scoring
• Historical activity analysis
• Source-level integrity checks
• Predictive spam trap detection

• Invalid or malformed addresses – hard bounces hurt reputation instantly
• Inactive or decayed addresses – lower engagement averages and inbox trust
• Bot-generated or disposable emails – unpredictable engagement patterns
• Trap addresses – immediate reputation risk

Even a small percentage of risky addresses can significantly reduce campaign performance.

• Before major campaigns or high-volume sends
• Quarterly or every 30–90 days, depending on list size and acquisition rate
• After acquiring new contacts from partners or third-party sources
• Ongoing monitoring for emerging risks, traps, or blacklists

Regular cleaning protects sender reputation and maximizes ROI.

Yes. By removing high-risk addresses and maintaining data integrity, we help:

• Increase engagement metrics (opens, clicks, replies)
• Reduce bounces and complaints
• Prevent trap hits and domain/IP throttling
• Create a positive reputation footprint recognized by mailbox providers

We follow strict standards for email handling:

• GDPR, CCPA/CPRA, CAN-SPAM, CASL compliance
• No resale or exposure of your email data
• Secure processing and encrypted storage
• Optional anonymized scanning for high-security use cases

• Predictive spam trap intelligence – goes beyond syntax checks with true actionalble insight. See our industry leading List Profile Report
• Behavioral risk scoring – engagement-based list insights
• Source-level integrity analysis – prevents high-risk addresses from entering your lists
• Real-time, multi-layered verification – identifies traps, bots, decayed addresses, and risky domains
• Compliance-first approach – ensures your lists are safe and legally sound

• Before major campaigns or volume spikes
• Periodic hygiene checks (e.g., quarterly)
• Monitor newly acquired lists, especially from third parties
• Use ongoing threat monitoring to catch blacklists or emerging risks

Because risk and data decay are continuous, regular checks keep deliverability and reputation healthy.

• Request a complimentary scan or sample report – no credit card, zero obligations
• Upload your list or sample data; receive a full diagnostic showing deliverability threats, risk scores, and recommended clean-up actions

• Better deliverability – fewer bounces and traps → more emails reach real inboxes
• Improved engagement & conversions – focus on active, likely-to-engage contacts
• Protected sender reputation – prevent spam foldering, blacklisting, and throttling
• Cleaner, more accurate databases – remove risky or junk contacts
• Reduced wasted spend and improved ROI – save ESP credits, cut bounce/complaint costs
• Comprehensive threat visibility & insights – detailed diagnostics and actionable recommendations

1. Import your list or upload sample data – full list or sample
2. Multi-layer scanning & analysis – syntax, domain health, mailbox acceptability, spam trap detection, disposable flags, behavioral risk scoring
3. Detailed reporting & diagnostics – “List Profile Report” flags risks and recommends actions. See our industry leading List Profile Report
4. Safe list cleaning & segmentation – suppress risky addresses, maintain safe segments
5. Ongoing protection & monitoring – optional add-ons like blacklist alerts

• Traditional verification only checks if a mailbox technically exists. It cannot detect spam traps, recycled addresses, bots, disposable emails, or decayed inboxes.
• Modern mailbox providers assess engagement, list hygiene, trap hits, bounce patterns, and data integrity. Verified-but-risky addresses can still harm deliverability.
• Impressionwise assesses risk, domain history, catch-all domains, and spam trap likelihood to deliver a reputation-optimized list.

• Invalid, non-existent, or malformed addresses
• Spam traps – pristine, recycled, or honeypots
• Disposable, temporary, catch-all, or accept-all domains
• Bot or automated signups, role-based accounts
• Inactive, exhausted, or decayed addresses
• Domains/addresses associated with blacklists or known threats
