Which is better: Apollo or Reply.io?

Quick Answer

Apollo wins for most B2B sales teams because it combines a massive proprietary contact database with outbound automation in a single platform — eliminating the need for a separate data vendor. Reply.io is the stronger pick for teams that need true multichannel sequence automation (LinkedIn, SMS, WhatsApp, calls) without a built-in database and are comfortable stitching it to a separate data source. Apollo's free-forever tier and credit-based pricing make it accessible at every company size; Reply.io's value proposition requires more upfront investment to unlock its multichannel depth.

Apollo vs Reply.io: Attribute Breakdown

Analytics

Apollo wins Winner

Apollo provides reporting across outbound sequences, inbound lead routing, deal execution, and meeting insights — a unified analytics layer across the full funnel. Reply.io's analytics are focused on sequence and email performance. For sales leaders who want one reporting surface, Apollo is more complete.

Free Trial

Apollo wins Winner

Apollo offers a free-forever Starter plan plus a trial with 50 credits and near-full feature access — no sales call required. This is a material advantage for teams doing self-serve evaluation. Reply.io does not offer a comparable free-forever tier based on available evidence.

Pricing Model

Apollo wins Winner

Apollo offers a free-forever Starter tier and clearly tiered paid plans with credit-based export limits. It is explicitly designed to be viable for companies of all sizes. Reply.io's pricing requires a paid plan to unlock meaningful multichannel features, and unlimited mailbox access is a marquee selling point that implies email-volume-heavy use cases at higher tiers.

Data Enrichment

Apollo wins Winner

Apollo operates one of the largest proprietary B2B contact databases on the planet and offers native Data Enrichment as a standalone product — cleansing and completing CRM records with always-fresh data. Reply.io has no built-in database; users must bring their own data from a separate provider. This is Apollo's single biggest structural advantage over Reply.io.

GDPR Compliance

Apollo wins Winner

Apollo explicitly states GDPR compliance on its pricing page and it is a headline trust signal (4.7/5 on 9,015 reviews, GDPR Compliant). Reply.io's GDPR posture is not substantiated in the available sources. For European teams or those selling into Europe, Apollo's stated compliance is the safer documented choice.

LinkedIn Safety

Reply.io wins Winner

Reply.io explicitly supports LinkedIn automation as a native channel, implying guardrails are built into the product. Apollo's LinkedIn steps are largely manual tasks, which actually carries lower automation risk but also lower scale. Neither tool is purpose-built for LinkedIn safety the way specialist tools like LGM are, but Reply.io at least treats it as a first-class automated channel.

Support Quality

Apollo wins Winner

Apollo holds a 4.7/5 rating across 9,015 G2 reviews, indicating consistently strong user satisfaction at scale. Reply.io holds a 3/5 on Gartner Peer Insights (6 reviews) versus Apollo's 4/5 (6 reviews) on the same platform. The volume and quality of Apollo's review base gives it a credibility advantage on support and overall satisfaction.

CRM Integrations

Reply.io wins Winner

Reply.io markets 70+ integrations as a core differentiator. Apollo integrates with major CRMs (Salesforce, HubSpot) natively but its integration breadth is not positioned as a headline feature. For RevOps teams with complex stacks, Reply.io's wider integration surface is the safer bet.

Personalization

Apollo wins Winner

Apollo's AI Assistant and AI-powered email generation with deep customization options — including video call analysis for deal execution — give it an edge on personalization quality per message. G2 reviewers highlight Apollo's AI-driven email as a key differentiator. Reply.io has AI SDR capabilities but personalization depth is less documented in available sources.

Sequence Builder

Reply.io wins Winner

Reply.io's sequence builder was designed from the ground up for multichannel branching logic across email, LinkedIn, calls, and SMS. Apollo's sequences are strong for email-first workflows and include AI-powered campaign creation, but the channel depth in branching is narrower. Teams running complex, multi-touch, multi-channel cadences will hit Apollo's ceiling faster.

Channels Supported

Reply.io wins Winner

Reply.io was built multichannel-first and supports email, LinkedIn, calls, SMS, and WhatsApp in native automated sequences. Apollo's core strength is email outreach; LinkedIn steps exist but are largely manual tasks within sequences. For teams whose playbook is genuinely multichannel, Reply.io has a structural advantage.

Email Deliverability

Apollo wins Winner

Apollo markets built-in email deliverability guardrails as a core feature of its outbound product. A Reddit user noted Apollo open rates of 20-25% vs. comparable Reply.io campaigns. Apollo's deliverability infrastructure is a stated product priority. Reply.io offers unlimited mailboxes which aids volume but deliverability tooling depth is less evidenced.

Cons

+Unlimited mailboxes on qualifying plans — strong for agencies or teams running high email volume
+70+ integrations make it easier to plug into complex RevOps stacks
+AI SDR capability for autonomous outreach execution
+Sequence builder designed for complex, multi-touch, multi-channel branching logic

Cons

-No free-forever tier based on available evidence; higher barrier to self-serve evaluation
-Lower user satisfaction scores than Apollo on both G2 and Gartner Peer Insights
-LinkedIn automation, while native, is not as safety-hardened as purpose-built LinkedIn outreach tools
