Closely

Closely is a cloud-based sales-engagement and outreach platform designed primarily for B2B prospecting across LinkedIn and email. It enables users to automate lead generation, message sequences, connection requests, and follow-ups while enriching contacts with verified data (emails, phone numbers, company info). It supports both individual sellers and teams in agencies or sales departments who want to scale outreach and simplify workflow. The tool emphasises safety in automation (such as human-like delays, warm-up modes, dedicated proxies for LinkedIn) and multi-channel campaigns (LinkedIn + email) from a unified dashboard. It integrates with popular CRMs and supports export/import of contact lists, making it relevant where companies already have a CRM stack or want to adopt one. Its value proposition is saving time in prospecting, increasing reply and engagement rates, and reducing manual effort in outreach workflows. The platform is accessible for non-technical users, with pre-built templates, sequences and an intuitive UI, while still offering more advanced features—such as AI-personalised messaging and lead-enrichment—to power more sophisticated campaigns.
