Turn synced outreach into signal-led conversations
Closely brings LinkedIn, email, enrichment, CRM sync, and a unified inbox together. Sonarly goes further upstream and downstream: find the audience, understand why now, execute the workflow, and manage replies with your AI agents.
The short answer
Choose Closely for a practical LinkedIn-and-email workspace with enrichment, CRM sync, AI personalization, and one inbox. Choose Sonarly when the outcome depends on integrated prospect discovery, deeper reusable signals, controlled execution, and an agent-ready path from prospect to conversation.
Do you need a synced outreach workspace or a signal-to-conversation system?
Both products support multichannel outbound, but they begin at different points. Closely organizes execution around contacts, campaigns, enrichment, CRM sync, and replies. Sonarly connects a broader prospecting and signal layer directly to campaign and conversation operations.
Find the people most likely to reply—then act on the reason why
Build the audience from 300M+ B2B profiles or LinkedIn sources, evaluate reusable intent and relationship signals, and carry that context into approved LinkedIn and Instantly workflows.
Closely: where it is strongest
Closely is strong when a team wants LinkedIn and email sequences, contact enrichment, CRM synchronization, AI-assisted personalization, and a unified inbox in one conventional sales-engagement workspace.
Move from more activity to better-timed activity
The Sonarly advantage is not another sending channel. It is the connected decision layer between who enters the audience, what changed, what should be said, how it is approved, and when a reply stops the workflow.
From prospect discovery to replies: Sonarly vs Closely
Compare how each product helps you find the audience, understand timing, create outreach, run campaigns, and manage replies.
Scale outreach with your AI agents
Sonarly is built as an agent-ready operating layer: discover prospects, evaluate signals, prepare outreach, approve content, launch campaigns, and review conversations through connected APIs and a bounded MCP surface.
- Find and enrich prospects from a 300M+ B2B database, Sales Navigator and LinkedIn sources, CSV files, or company websites.
- Evaluate five signal families and 45+ published intents, or define reusable custom signal specifications.
- Build campaigns from 16 selectable steps across conditions, waits, scans, approvals, LinkedIn actions, and Instantly email.
- Keep humans in control with review, approval, suppression, scheduling, activity history, and stop-on-reply behavior.
Closely advertises Sales AI agents, integrations, API access, and workflow automation. Sonarly exposes lifecycle APIs plus a bounded supported MCP surface, so external agents can work across prospecting, signals, campaign preparation, approvals, and conversation review. Signal-triggered campaign start is not yet generally available and still requires explicit orchestration.

Sonarly: turn prospect context into the next best action
Start with the right audience—not another export
Use 300M+ B2B profiles or bring in Sales Navigator searches and lists, LinkedIn search and engagement, CSV files, and company websites. Sonarly connects the audience to enrichment, signals, campaigns, and conversations.
Know why each prospect is worth contacting now
Reuse signal specifications across audiences, inspect source and score reasoning, and combine one-time scans, monitoring, or workflow checks. That makes timing a first-class input instead of a personalization field added after list creation.
Turn context into controlled execution
Build conditions, waits, signal scans, approval steps, LinkedIn actions, and Instantly email in one workflow. Sender protections, suppression, scheduling, cleanup, and stop-on-reply behavior remain visible and controllable.
