Apollo vs Salesloft vs Outly: Which Sales Engagement Platform Is Right for Your Team?
TL;DR
Apollo wins for most growing teams: it's affordable, includes a contact database, and gets you running fast. Salesloft wins for enterprise teams with mature sales processes and Salesforce as the system of record. Outly wins when LinkedIn is your primary outreach channel and you want AI-personalized messages with human review before sending. Read on for the full breakdown.
Note: This comparison focuses on the core use cases for each tool. No single platform is best for everyone — the right choice depends on your team size, budget, and primary outreach channel.
What Is Apollo?
Apollo.io is a sales intelligence and engagement platform. It started as a B2B data company and expanded into outreach automation. Today it combines a 275M+ contact database with email sequencing, LinkedIn touchpoints, calling, and a CRM layer.
Apollo's positioning: an all-in-one prospecting and engagement tool for teams that need to build pipeline from scratch. It's particularly popular with startups, SMBs, and SDR teams that want data and outreach in one place without enterprise pricing.
What Is Salesloft?
Salesloft is a sales engagement platform built for enterprise. It doesn't have a built-in contact database — it assumes you already have data and focuses on helping your reps execute structured outreach cadences across email, phone, and LinkedIn.
Salesloft's positioning: a platform for large, process-driven sales organizations that need manager visibility, rep coaching, and deep CRM integration. Its "Rhythm" feature uses AI to surface the next best action for each rep based on deal signals and engagement data.
What Is Outly?
Outly is a LinkedIn-first outreach automation platform with a human-in-the-loop review workflow. The AI drafts personalized connection requests and follow-up messages based on each prospect's LinkedIn profile and recent activity. You review and approve before anything sends.
Outly's positioning: the best tool for teams where LinkedIn is the primary pipeline channel. It doesn't try to replace a full sales engagement platform — it specializes in LinkedIn outreach and does it better than generalist tools.
Apollo vs Salesloft vs Outly: Prospecting and Contact Data
Database Access and Quality
Apollo has a 275M+ contact database with strong US coverage. You can search by job title, company size, industry, technology stack, funding stage, and dozens of other filters. The data quality is good for most use cases, though bounce rates can be higher than expected for contacts outside North America.
Salesloft has no native contact database. You import contacts from your CRM, CSV files, or third-party integrations. If your team already has a solid data workflow, this isn't a problem. If you're starting from scratch, you'll need a separate data tool.
Outly doesn't include a contact database either. It's designed to work with prospects you've already identified — typically from LinkedIn search or Sales Navigator. Many teams use Apollo to find and enrich leads, then Outly to run the LinkedIn outreach.
Data Enrichment and Intent Signals
Apollo includes enrichment and intent data (powered by Bombora). You can enrich existing contact lists and surface accounts that are actively researching solutions like yours.
Salesloft has basic intent signals through integrations, but it's not a data enrichment tool.
Outly doesn't include enrichment or intent data. It focuses on the outreach side.
Winner: Apollo for teams that need data. Outly for LinkedIn outreach quality.
Apollo vs Salesloft vs Outly: Outreach and Engagement
Email Capabilities
Apollo has a solid email sequence builder. Multi-step sequences, A/B testing, scheduling, and analytics are all included. The AI email writer generates drafts, though the output is decent rather than exceptional.
Salesloft has a more polished email cadence builder with better team-level controls, step-level analytics, and manager visibility. It's designed for teams where multiple reps run the same playbook.
Outly doesn't handle email outreach. It's LinkedIn-only.
LinkedIn Automation
Apollo supports LinkedIn steps in sequences, but the automation runs via a Chrome extension. Campaigns pause when your browser closes, and the safety profile is lower than cloud-based tools.
Salesloft also supports LinkedIn steps, with similar extension-based limitations.
Outly is built specifically for LinkedIn. Cloud-based infrastructure means campaigns run 24/7 without your browser open. The AI drafts personalized messages for each prospect, and you review before sending. This combination — cloud reliability plus human review — produces higher acceptance rates and better account safety than extension-based approaches.
Calling Features
Apollo includes a built-in dialer on higher-tier plans with call recording and basic conversation intelligence.
Salesloft has more sophisticated calling features through its Conversations product, including AI-powered call transcription and coaching.
Outly doesn't include calling.
Winner: Salesloft for email and calling. Outly for LinkedIn. Apollo for all-in-one at lower cost.
Apollo vs Salesloft vs Outly: CRM and Workflow Integration
CRM Sync Capabilities
Apollo integrates with Salesforce, HubSpot, Pipedrive, and others. The sync is reliable for most use cases, though enterprise teams sometimes run into data hygiene issues.
Salesloft has the deepest CRM integration of the three. Bidirectional Salesforce sync is tight, activity logging is thorough, and deal stage changes flow cleanly. For teams where Salesforce is the system of record, Salesloft's integration is best-in-class.
Outly doesn't currently include CRM integration. It's focused on the LinkedIn outreach workflow.
Team Collaboration
Apollo has basic team features — shared sequences, team analytics, and user management.
Salesloft has enterprise-grade team features: manager dashboards, rep performance tracking, coaching tools, and governance controls for cadences.
Outly has team features focused on LinkedIn campaign management and approval workflows.
Workflow Automation
Apollo supports conditional logic in sequences (if email opened, send follow-up A; if not, send follow-up B). It's functional but not as sophisticated as enterprise tools.
Salesloft's Rhythm feature uses AI to dynamically prioritize each rep's daily task list based on deal signals and engagement data. This is genuinely differentiated for large teams.
Outly automates the LinkedIn outreach workflow with AI drafting and human approval.
Winner: Salesloft for enterprise CRM needs. Apollo for most other teams.
Apollo vs Salesloft vs Outly: Analytics and Reporting
Performance Metrics
Apollo covers the basics: open rates, click rates, reply rates, and meeting booked rates at the sequence and step level. Good for individual contributors and small teams.
Salesloft has more granular analytics: rep-level performance, sequence-level analytics, step-level drop-off analysis, and revenue attribution. Built for sales managers who need visibility into team performance.
Outly tracks LinkedIn-specific metrics: connection acceptance rates, reply rates, and campaign performance over time.
Team Analytics
Apollo has team-level reporting but it's less comprehensive than Salesloft.
Salesloft has the most detailed team analytics of the three, including rep performance dashboards and coaching insights.
Outly focuses on campaign-level analytics rather than team performance.
A/B Testing
Apollo supports A/B testing on email sequences.
Salesloft supports A/B testing with more granular controls and statistical significance tracking.
Outly supports A/B testing on LinkedIn message templates.
Apollo vs Salesloft vs Outly: AI and Automation
AI Writing Capabilities
Apollo's AI email writer generates sequence drafts from a brief. Quality is decent for standard outreach but produces fairly generic output without significant customization.
Salesloft's AI focuses more on prioritization and coaching than on writing. The Rhythm feature surfaces next best actions; the Conversations product analyzes calls.
Outly's AI is built specifically for LinkedIn personalization. It analyzes each prospect's profile, recent posts, and company activity to draft messages that feel genuinely tailored. The human review step ensures quality before anything sends.
Personalization at Scale
Apollo supports personalization variables in email templates. The AI can generate personalized first lines, but the depth of personalization is limited.
Salesloft supports personalization in cadences but relies more on rep judgment than AI for message quality.
Outly is built around personalization at scale. The AI handles the research and drafting; you handle the approval. This produces LinkedIn outreach that reads like it was written for one person — because the final version always is.
Automation Intelligence
Apollo automates email and LinkedIn sequences with basic conditional logic.
Salesloft's Rhythm feature is the most sophisticated automation intelligence of the three — dynamically prioritizing rep tasks based on deal signals.
Outly automates the LinkedIn outreach workflow with AI drafting, human approval, and follow-up sequencing.
