Lead Generation

Direct-response lead-gen programmes live or die by inbox rate. Whether you are running lender comparison, insurance quotes, home services or high-ticket B2C, the sending infrastructure is the acquisition channel.

Challenges

  • List quality varies dramatically across sources and offers
  • TCPA, CAN-SPAM and equivalent regulations impose per-recipient constraints
  • Complaint rates in the vertical hover near the acceptance threshold
  • Bounce management directly affects unit economics

Our approach

  • Per-source, per-offer IP isolation
  • Aggressive suppression of low-quality lead sources upstream of the send
  • Bounce classification tied back to the source for supplier scoring
  • Continuous complaint monitoring with immediate remediation triggers

Deliverability recommendations

  1. Score lead sources by complaint rate weekly; deprecate sources above 0.3%
  2. Enforce list-unsubscribe headers on every outbound
  3. Aggressive re-engagement suppression at 90 days

Example engagements

  • US lender-comparison operator: audit of nine lead suppliers found two producing 61% of complaints; suppression of those two lifted Gmail inbox rate 14 points.
