Feature Deep Dive

Outreach Automation Capabilities

Closely

Strengths
  • Safe LinkedIn sequences with human-like behavior
  • Multichannel campaigns blending LinkedIn and email
  • AI personalization for messages and emails
  • Unified inbox for managing replies
  • Conditional sequences in Custom tier
Workflow

Build sequence → Add AI personalization → Schedule multichannel → Monitor unified inbox → Analyze responses

PhantomBuster

Strengths
  • Prebuilt Phantoms for LinkedIn actions like connections and messages
  • Workflow builder to chain automations
  • Scheduling for recurring runs
  • Execution logs for monitoring
  • Flexible for custom scripts
Workflow

Select Phantoms → Chain in workflow → Set triggers/schedules → Run and debug via logs → Extract data

Closely is superior for safe, multichannel outreach with AI and inbox management, ideal for sales teams. PhantomBuster offers more flexible chaining for technical users but lacks email integration and safety features, making it better for data-driven automations.

Data Enrichment & Lead Research

Closely

Strengths
  • Verified emails and phones from LinkedIn profiles
  • Exports from Sales Navigator, posts, events
  • AI Sales Agents for research, qualification, scoring
  • Credit-based enrichment (e.g., 750 emails/150 phones in Growth)
Workflow

Import leads → Enrich with AI/web research → Score and qualify → Export to CRM

PhantomBuster

Strengths
  • Phantoms for extracting leads from LinkedIn and other sources
  • Data enrichment via chained workflows
  • Integrations with spreadsheets for bulk processing
  • API for advanced extraction
Limitations
  • No built-in AI for qualification or scoring
  • Requires manual configuration for enrichment

Closely provides more automated, AI-driven enrichment and qualification, streamlining sales pipelines. PhantomBuster excels at raw data extraction at scale but requires more setup for enrichment, suiting growth hackers over sales pros.

Integrations & CRM Sync

Closely

Strengths
  • Deep native integrations with HubSpot, Salesforce, Pipedrive, GoHighLevel
  • Automatic CRM attribution for outreach
  • Webhooks in Custom tier
  • Seamless data sync from campaigns
Limitations
  • Focused on major CRMs; no broad Zapier

PhantomBuster

Strengths
  • Integrations with CRMs, spreadsheets, and Zapier
  • API access for custom integrations
  • Chaining Phantoms to push data to tools
Limitations
  • Less 'deep' CRM sync; more export-oriented

Closely wins for sales teams needing tight CRM integrations and attribution. PhantomBuster is better for flexible, tool-agnostic integrations via Zapier and API, appealing to technical setups.

Analytics & Team Management

Closely

Strengths
  • Advanced analytics for campaigns, sequences, teams
  • CRM-attributed metrics
  • Team management in higher tiers
  • White-label reporting for agencies

PhantomBuster

Strengths
  • Execution logs and error reporting
  • Usage analytics for Phantoms
  • Shared workspaces in Team tier
  • Priority support in higher plans
Limitations
  • Less outreach-specific analytics
  • No white-label options

Closely offers richer, sales-focused analytics and agency tools. PhantomBuster provides solid debugging but lacks depth in campaign insights, better for monitoring automations than ROI tracking.
