Category: B2B contact database with triple-verified email addresses

Website: listkit.io

Also known as: listkit.

Overview

ListKit is a B2B prospecting database built specifically for cold email operations. The platform triple-verifies email addresses before surfacing them, running each address through multiple verification passes to reduce bounce rates before prospects even hit your sending platform. The database covers 500M+ verified contacts with phone numbers, LinkedIn profiles, and technographic data. Where ListKit differentiates from ZoomInfo and Apollo is its focus on deliverability: the company filters out addresses that typically cause bounce and spam complaint problems (role-based addresses, catch-alls, recently churned accounts) before you download them. The search filters cover standard fields like company size, industry, revenue, geography, and job title, with additional filters for funding stage, tech stack, and recent hiring signals. For cold email practitioners who know that data quality directly impacts deliverability, the extra verification layer is worth the price premium over raw data dumps from cheaper sources.

Pricing

$197/month for 1,000 verified export credits. $397/month for 3,000 credits. Credits roll over month to month.

Strengths

  • Triple-verified email addresses reduce bounce rates before data hits your sending platform
  • 500M+ contact database with strong coverage across SMB and mid-market segments
  • Built specifically for cold email practitioners rather than general CRM enrichment
  • Filters for funding, hiring signals, and tech stack for intent-based prospecting
  • Credits roll over — no pressure to use them or lose them
  • Phone number coverage for multi-channel sequences

Weaknesses

  • Credit-based model limits how much you can export per month at base tier
  • Enterprise-level contacts (Fortune 500 C-suite) thinner than ZoomInfo
  • No real-time enrichment API for CRM auto-fill workflows
  • Newer platform — smaller track record than Apollo or ZoomInfo for enterprise teams

Best For

  • Cold email agencies and SDR teams that buy data in bulk and need low bounce rates
  • Operations targeting SMB and mid-market where ListKit's database is strongest
  • Teams tired of cleaning dirty lists from cheaper data providers after the fact
  • Practitioners who understand that data quality is an infrastructure problem, not just a prospecting problem

Not Ideal For

  • Enterprise teams needing deep Fortune 500 coverage and real-time CRM enrichment
  • Teams that need an enrichment API rather than export-based workflows
