Closely
LinkedIn outreach, minus the manual work
What is Closely
Closely runs LinkedIn and email outreach from a single workspace — automating connection requests, profile visits, follow-up sequences, and AI-written message personalization across both channels. It's built for SDRs, BDRs, and outbound agencies at SMBs and mid-market companies that need to move fast without hiring a larger team. The standout capability is ICP-based lead qualification paired with AI-powered company research, which lets reps import leads from LinkedIn Sales Navigator and immediately score and personalize outreach without switching tools. Closely also finds verified emails and direct dials, then syncs results to HubSpot, Salesforce, or Pipedrive. Where it falls short: there's no public API, so you can't wire it into custom workflows or agent pipelines — what you see in the UI is what you get.

Vanderbuild take
Closely is a self-contained multichannel outreach tool that covers the LinkedIn automation + email sender stack in one seat-based product — a practical fit for SDR teams and outbound agencies that want to run coordinated sequences without stitching together separate tools. On the agentic readiness front, there's no API and no MCP server, meaning you can't drive this from an AI agent or external orchestration layer; it's UI-only, full stop. Pricing starts at $29/month annually, which is accessible for small teams, but credits for enrichment and AI personalizations are metered, so costs climb as volume scales. The other honest constraint: reporting stays at the campaign level — if you need cross-campaign attribution or pipeline influence data, you'll need to pull that from your CRM rather than from Closely itself.
