Folderly Lens

Folderly Lens is a zero-credential domain and IP audit tool designed for cold email operators who need to assess infrastructure risk before it destroys deliverability. By scanning public DNS, authentication records, MX configurations, IP rDNS, and blacklist signals, it delivers actionable KILL / REHAB / KEEP verdicts with copyable fix plans — no signup, no mailbox access, and no test sends required.

Product Highlights

• Zero-Credential Auditing: Run complete estate scans without API keys, inbox connections, or platform access — every signal is drawn from the same public view that Gmail and Spamhaus already see.
• Deterministic Verdict Engine: Receive transparent KILL, REHAB, or KEEP classifications with exact driver lists, risk bands, and shareable CSV registers your team can execute immediately.
• Comprehensive Signal Collection: Covers SPF with recursive lookup analysis, 16-selector DKIM probing, DMARC enforcement, MX/NS/A records, IP PTR/rDNS, forward-confirmed rDNS, RDAP/WHOIS registration patterns, TLS, and 100+ DNSBL/RBL checks.
• Remediation-Proof Reporting: Re-run the same deterministic collector before and after fixes to generate before/after diffs — turning "Did remediation work?" from opinion into measurable fact.
• Weekly Drift Monitoring: $149/month estate monitoring catches SPF/DMARC configuration drift and new blacklist hits before they impact sending reputation.

Use Cases

• Pre-Launch Estate Validation: Audit reseller-purchased domain batches before connecting them to your sequencer — catch SURBL listings, shared IP fates, and registration-burst patterns that providers hide behind "isolated infrastructure" claims.
• Post-Incident Recovery: When deliverability crashes, run a full register to identify whether the root cause is authentication failure, IP reputation damage, or blacklist exposure — then prove remediation worked with re-scans.
• Agency Client Onboarding: White-label 90-domain estate audits for clients bringing legacy infrastructure, replacing ~8 hours of manual auditing per client with reproducible external collector runs.
• Reseller Verification: Test claims of "isolated sending infrastructure" by checking whether provider labels match actual MX, SPF includes, and IP rDNS configurations — as demonstrated on the documented 90-domain ThePerfectFranchise case.

Target Audience

Folderly Lens serves cold email agencies, outbound sales teams, and deliverability consultants managing 15+ sending domains who need audit-grade visibility without platform integration overhead — particularly those acquiring domains from resellers and requiring evidence-based risk assessment before infrastructure investment.
