Folderly Lens

Product Introduction

1. Definition: Folderly Lens is an external, passive domain and IP reputation auditing platform. It is a technical SaaS tool designed for cold email and outbound marketing teams to perform non-intrusive, comprehensive health checks on their sending infrastructure.
2. Core Value Proposition: It exists to solve the critical problem of "unknown sender reputation damage." Most email campaigns run on damaged domains without the sender's knowledge. Folderly Lens provides instant, actionable visibility into public DNS, authentication, and blacklist signals to deliver a deterministic KILL, REHAB, or KEEP verdict for each asset, enabling data-driven domain estate management.

Main Features

1. External Collector Engine: This is the core scanning technology. It performs live, public-facing checks without requiring access to private sending platforms, mailboxes, or API keys. It works by querying public DNS records (SPF, DMARC, DKIM, MX, A), performing IP rDNS (PTR) and forward-confirmed rDNS checks, probing 16 common DKIM selectors, checking RDAP/WHOIS registration data for burst patterns, and querying major public DNS-based blacklists (DNSBLs/RBLs) like Spamhaus and SURBL.
2. Deterministic Verdict System (KILL/REHAB/KEEP): The platform applies a transparent, rules-based precedence algorithm to the collected signals to assign a final, actionable verdict per domain or IP. "KILL" indicates critical, often unsalvageable issues like SURBL listings. "REHAB" signals fixable problems like missing DMARC enforcement. "KEEP" confirms the asset is clean. Each verdict comes with a specific, copyable fix plan detailing the exact technical issues found.
3. Estate-Wide Audit & Monitoring: Beyond single-domain checks, Folderly Lens can ingest and audit entire estates (lists of domains and IPs) via CSV or pasted text. The Monitor tier ($149/mo) provides weekly re-scans, change-only alerts for new DNSBL hits, SPF/DMARC configuration drift detection, and remediation tracking through before/after diff reports, turning a one-time audit into continuous infrastructure hygiene.

Problems Solved

1. Pain Point: "Infrastructure Blindness" in cold email operations. Teams purchase domains in bulk from resellers or use services claiming "IP isolation," but have no independent, technical verification of their actual public reputation, authentication setup, or shared infrastructure risk, leading to poor deliverability and wasted spend.
2. Target Audience: B2B outbound sales agencies, cold email operations teams, marketing agencies running multi-domain campaigns, and IT/ops professionals responsible for corporate email sender reputation. Specifically, users managing 8-90+ sending domains who need scalable audit processes.
3. Use Cases: Essential for auditing a newly purchased domain portfolio from a reseller; verifying claims made by infrastructure-as-a-service email providers; conducting pre-campaign due diligence on sending assets; diagnosing sudden deliverability drops by checking for new blacklistings; and providing proof of remediation effectiveness to stakeholders or clients.

Unique Advantages

1. Differentiation: Unlike deliverability consultants who require platform access and manual work, or single-point diagnostic tools, Folderly Lens automates the full external audit cycle. It differs from its sibling product Folderly Solo (for single email analysis) by focusing on estate-wide infrastructure risk. It provides more actionable, asset-specific verdicts than generic "domain health" checkers.
2. Key Innovation: The product's foundation is its credibility anchor – it uses only public signals (the same data mailbox providers like Gmail see). This makes its findings 100% reproducible and removes opinion from the audit process. The deterministic verdict engine and the ability to "diff" scans pre- and post-remediation objectively answer "Did the fix work?"

Frequently Asked Questions (FAQ)

1. How does Folderly Lens work without accessing my email account? Folderly Lens performs entirely passive, external checks. It queries public DNS records (SPF, DMARC, MX), checks public IP blacklists (RBLs), validates rDNS, and examines RDAP/WHOIS data. These are the same signals that receiving mail servers (like Gmail or Outlook) use to evaluate your emails, requiring no internal access to your sending platform or inbox.
2. What is the difference between a KILL and a REHAB verdict? A KILL verdict is assigned when an asset has critical, often permanent reputation damage, such as being listed on a severe blacklist like SURBL, indicating the domain should be retired. A REHAB verdict indicates fixable issues, such as a missing DMARC record or an SPF syntax error, providing a clear plan to repair the domain's sending reputation.
3. Is the free Folderly Lens scan a limited trial? The free scan (up to 10 assets) uses the same external collector engine as the paid audit, providing full SPF, DMARC, MX, and RBL checks with a KILL/REHAB/KEEP verdict. The paid Audit tier adds deeper signals like 16-selector DKIM probing, SURBL checks, RDAP/WHOIS history, and delivers a comprehensive per-asset register with CSV export.
4. Can Folderly Lens verify if my domains are truly on isolated IP infrastructure? Yes. By pasting your actual sending IPs into the scanner, Folderly Lens checks the PTR (rDNS) records and queries public IP reputation blacklists. This provides technical evidence to verify or refute claims of infrastructure isolation, moving beyond provider labels to actual public data.
5. Who should use Folderly Lens versus other Folderly products? Use Folderly Lens if you manage multiple sending domains or IPs (an "estate") and need to audit and monitor their public health. Use Folderly Solo if you are a solo sender testing one specific cold email's content and setup. For ongoing, managed deliverability and inbox placement support, the core Folderly platform is the appropriate solution.
