Problem
Sales and marketing teams spend excessive time manually locating, cleaning, and validating prospect contact information, leading to high bounce rates, outdated lists, and reduced outreach efficiency. Data decay—especially job changes and invalid emails—causes missed opportunities and wasted campaign spend.
Solution
Scalelist delivers a cloud‑native B2B data platform that automates the discovery and verification of professional email addresses and mobile phone numbers. Its Email Finder queries multiple premium sources to achieve up to 95 % coverage, while the Email Verifier applies SMTP, MX, catch‑all, and spam‑trap checks to guarantee ~99 % deliverability. A Chrome extension captures contact details directly from LinkedIn and other web sources, and the Lead Mobile Finder enriches lists with verified direct dials. Real‑time Monitoring continuously tracks job or company changes and flags stale records. The service integrates with HubSpot, Salesforce, Zapier, and other CRMs via a RESTful API, allowing seamless enrichment, export, and automated workflow orchestration for outbound prospecting.
Target Audience
Primary users are B2B sales development representatives, outbound marketing agencies, and founders building go‑to‑market pipelines who need reliable contact data at scale.
