SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Building outbound prospect lists manually leads to poor coverage, duplicate contacts, invalid emails, and high bounce rates that damage sender reputation. This Skill provides a structured framework for defining ICPs, sourcing companies and contacts from multiple databases, scoring accounts, and validating data before outreach. ## Core Features & Use Cases - ICP Definition & Scoring: Build a 100-point scoring matrix across firmographic, technographic, and behavioral criteria, then assign accounts to A/B/C/D tiers for ABM prioritization. - Multi-Source Discovery: Find companies via Clay, Apollo, Sales Navigator, Google Maps, and 62+ underused data sources; find contacts with boolean search formulas and export tools like Evaboot. - Data Quality & Hygiene: Verify emails with ZeroBounce/NeverBounce, deduplicate across sources, and maintain list hygiene schedules targeting <1% bounce rates. - Use Case: A sales team needs 5,000 verified VP-level contacts at mid-market SaaS companies. The Skill routes them through ICP definition, Sales Navigator boolean search, Evaboot export, Clay enrichment, email waterfall verification, and deduplication before pushing to a sequencer. ## Quick Start Ask the assistant to build a prospect list of VP Marketing contacts at SaaS companies with 50-500 employees, including ICP scoring and email verification.

FAQPage Schema
How do I build a B2B prospect list for cold outreach?▼

Start by defining your ICP with firmographic and technographic criteria, then source companies from Clay, Apollo, or Sales Navigator. Find contacts with boolean search, verify emails with ZeroBounce or NeverBounce, and deduplicate before pushing to a sequencer.

How do I bypass the Sales Navigator 2,500 result limit?▼

Segment your search by geography, industry, company size, seniority level, first name ranges, or time filters like job changes in the past 90 days. Each segmented search returns its own 2,500-result set.

What email verification tool should I use for list cleaning?▼

Choose by volume: Findymail for under 1K emails monthly, NeverBounce for 1K-10K with a 99.9% guarantee, and MillionVerifier for 10K+ at the lowest cost. Add ListKit for catch-all sub-verification.

How do I score and tier accounts for ABM campaigns?▼

Apply a 100-point ICP scoring matrix covering industry, size, revenue, geography, technology fit, growth, and intent signals. Assign Tier A (90-100) to 1:1 ABM, Tier B (70-89) to 1:few, Tier C (50-69) to programmatic, and exclude Tier D.

Why is my cold email bounce rate above 3%?▼

High bounce rates come from unverified or decayed data, since emails decay 22-30% annually. Pause campaigns immediately, re-verify the full list, remove invalid and catch-all addresses, and re-verify any list older than 30 days before sending.

How do I deduplicate leads from Apollo and Sales Navigator?▼

Match on email address as the primary key, then LinkedIn URL, then first name plus last name plus company domain. Expect 30-60% overlap between Apollo and Sales Navigator, and maintain a master suppression list across campaigns.
