Every sales team eventually hits the same wall: reps spend more time searching for contacts and copying emails than actually selling. Sales engagement software exists to fix that, and two names dominate the conversation in 2026: Reply.io and Apollo.io.
Both promise to automate your outbound. Both promise more replies, more meetings, more pipeline. But they solve the problem from different angles, and picking the wrong one means paying for tools you don't need while missing the ones you do.
This guide breaks down what each platform actually offers, what it really costs once you look past the sticker price, and who should choose which one.
The Short Answer Before the Details
If you only have a minute, here it is.
- Apollo.io is a combined contact database and sales engagement platform. It bundles prospecting data, sequencing, a dialer, and CRM sync into one subscription, making it the strongest choice for teams that need to find leads and reach out to them without stitching together separate tools.
- Reply.io is a dedicated multichannel sales engagement platform built around sequence quality, conditional logic, and an AI SDR agent called Jason. It works best for teams that already have contact data and want the most refined outreach engine to run it through.
If your biggest gap is finding verified contacts at scale, Apollo.io solves that problem natively. If your biggest gap is running sophisticated multichannel sequences with strong branching logic, Reply.io is built specifically for that job.
Now let's get into the details that actually matter for your budget and your pipeline.
What Is Apollo.io?
Apollo.io is a sales intelligence and engagement platform built around one core idea: give sales teams a massive contact database and the tools to act on it, all inside one workspace.
Founded in 2015, Apollo has grown into one of the most widely used platforms in B2B sales, with over 500,000 companies using it and a database that now claims more than 210 million contacts and 30 million companies.
Here is what the platform bundles together:
- Contact database and search – filter by job title, company size, technology stack, hiring signals, and funding events
- Multichannel sequencing – automated cadences across email, LinkedIn, and phone
- Built-in dialer – power and parallel dialing with call recording, supporting calls to over 100 countries
- AI tools – an AI Research Agent for account intelligence, an AI Sequence Builder that generates cadences from natural language prompts, and AI-assisted email writing
- CRM integrations – native sync with HubSpot, Salesforce, Outreach, and Salesloft
- Inbound lead management – capture and enrich website visitors and form submissions automatically
The pitch is simple: instead of paying separately for a data provider like ZoomInfo, a sequencing tool, and a dialer, you get all three in one subscription. For teams under 25 reps, especially US-focused ones, that pitch holds up well in practice.
You can explore the current plans and start on the free tier through Apollo.io's official platform.
What Is Reply.io?
Reply.io is a multichannel sales engagement platform focused specifically on the quality and sophistication of its outreach sequences.
Where Apollo leads with its database, Reply.io leads with its sequence builder. It has been refining multichannel cadences for years, and it shows in the conditional logic available: if a prospect opens an email but doesn't reply, escalate to LinkedIn; if there's no LinkedIn response after three days, trigger a call task. That kind of branching is more sophisticated than what most competitors offer out of the box.
Core features include:
- Multichannel sequences – email, LinkedIn, calls, and SMS combined into a single automated cadence
- Jason AI – an AI SDR agent that can define your ideal customer profile, source leads, write personalized messages, and handle replies autonomously
- AI sequence generator – built into every paid plan for faster cadence creation
- Email warm-up – unlimited mailboxes and warm-up included starting on the entry tier
- CRM integrations – native sync with Salesforce, HubSpot, and Pipedrive on higher tiers
- Agency tools – centralized multi-client management for agencies running outbound on behalf of multiple businesses
Reply.io does not include a large native contact database the way Apollo does. It assumes you either already have contact lists or are willing to pair it with a separate data provider.
You can test the platform's sequencing tools directly through Reply.io's official site, which offers a 14-day trial on paid plans.
Apollo.io vs Reply.io: What Problem Are You Actually Solving?
This is the question to answer honestly before comparing pricing line by line.
Choose Apollo.io if:
- You need to find new B2B contacts, not just message the ones you already have
- You want a single subscription that replaces a data provider, a sequencer, and a dialer
- Your team is under 25 reps and mostly focused on the US market
- You want built-in AI research and lead scoring alongside outreach
Choose Reply.io if:
- You already have contact lists or a separate data source and need the strongest possible sequencing engine
- Multichannel branching logic (email, LinkedIn, calls, SMS in one adaptive cadence) is your top priority
- You want an AI SDR agent that can run outbound with less manual oversight
- You run an agency managing outbound for multiple clients from one dashboard
If your gap is "we don't have enough leads," Apollo's database solves that directly. If your gap is "we have leads but our outreach isn't converting," Reply.io's sequencing depth is the better investment.
Pricing Comparison: Apollo.io vs Reply.io
Both platforms look affordable on the pricing page. Both get more expensive once you understand what's actually included at each tier. Here is the real breakdown.
Apollo.io Pricing
Apollo uses a hybrid model: a fixed per-seat price plus a credit system that governs how many contacts you can reveal, export, or enrich.
- Free: $0/month, includes 10,000 email credits per month (corporate domain only), 5 mobile credits, 10 export credits, and 2 active sequences. Gmail integration only.
- Basic: Around $49/user/month on annual billing, includes 5,000 data credits per year, unlimited sequences, and CRM integration with HubSpot and Salesforce. No AI features at this tier.
- Professional: Around $79/user/month on annual billing, includes 10,000 data credits per year, advanced reporting, AI-assisted email writing, and a dialer with call recording.
- Organization: Around $119/user/month on annual billing, includes 15,000 data credits per year, 200 mobile credits per month, an international dialer, custom reports, and single sign-on. This tier requires a minimum of three seats.
Monthly billing runs higher across the board, typically landing closer to $59, $99, and $149 per user.
The catch with Apollo is the credit system. Credits are consumed by revealing contacts, exporting data, and using certain AI features, and they do not roll over month to month. Heavy outbound teams frequently report real spend landing well above the advertised per-seat price once overages are factored in.
You can review the current tiers and credit allowances directly on Apollo.io's official pricing page before committing, since credit allocations have shifted more than once over the past year.
Reply.io Pricing
Reply.io splits its pricing into two separate products: the core sales engagement platform, priced per seat, and Jason AI, priced separately based on contact volume and credits.
For the sales engagement platform:
- Starter: Around $49 to $59/user/month on annual billing, includes unlimited mailboxes, unlimited email warm-up, roughly 1,000 active contacts, and around 50 live data credits. This tier is email-only, with no multichannel sequencing.
- Professional: Around $89/user/month on annual billing, unlocks multichannel sequences across email, LinkedIn, calls, and SMS, plus CRM integrations with Salesforce, HubSpot, and Pipedrive. This is the tier most active outbound teams land on.
- Ultimate: Around $139/user/month on annual billing, includes the full AI suite, the highest contact and sending limits, and advanced reporting and integrations.
- Agency: Starting around $166 to $210/month, built for managing outbound across multiple client accounts from one dashboard.
For Jason AI, the standalone AI SDR product:
- Starter tier: Roughly $500 to $800+/month, supporting 1,000 to 3,000 active contacts
- Growth tier: Roughly $1,500 to $3,000/month, supporting 5,000 to 10,000 active contacts
- Enterprise: Custom pricing for higher volumes
Monthly billing without an annual commitment runs noticeably higher across every tier.
The important detail here: LinkedIn automation, calling, and SMS are bundled into the Professional plan itself in the current structure, rather than sold as separate add-ons on top of Starter. If your team needs true multichannel outreach, budget for Professional as your realistic starting point, not Starter.
Check current numbers directly on Reply.io's official pricing page, since Jason AI pricing in particular has changed more frequently than the core platform.
Which Pricing Model Actually Wins for You?
Run this quick gut check before deciding.
- If you need contact data and outreach together, Apollo's bundled approach is more cost-effective than buying a data provider and a sequencer separately.
- If you already have verified contact lists and just need best-in-class sequencing, Reply.io's Professional tier gives you more sequencing sophistication for a comparable price.
- If your team is under 25 reps and US-focused, Apollo's free and Basic tiers offer real usable value before you need to upgrade.
- If you want to replace SDR headcount with AI, Reply.io's Jason AI is a more mature, purpose-built product than Apollo's AI features, though it costs significantly more.
- If you're an agency running outbound for multiple clients, Reply.io's dedicated agency plan is built for that workflow in a way Apollo does not directly offer.
Feature-by-Feature Comparison
Contact Database and Data Quality
This is Apollo's clearest advantage. Its database spans more than 210 million contacts and 30 million companies, with over 65 search filters covering job title, seniority, technology stack, hiring signals, and funding events.
Apollo claims high email accuracy, though independent reviewers report real-world US accuracy closer to 88%, dropping to 60 to 73% for contacts outside North America. Mobile number hit rates for US-based VPs have been measured around 35%, which trails dedicated data providers like ZoomInfo or Lusha.
Reply.io does not compete on database size. It focuses on running sequences against contacts you already have or import, rather than being a primary source of new leads. If contact discovery is your priority, Apollo's built-in database removes the need for a separate data subscription entirely.
Sequencing and Multichannel Depth
This is where Reply.io pulls ahead. Its sequence builder supports genuinely sophisticated conditional logic: branching based on opens, replies, and channel-specific engagement, executed reliably across email, LinkedIn, calls, and SMS.
Apollo's sequencing covers the same channels, email, LinkedIn, and phone, and is competitive for most standard use cases. But several reviewers note that Apollo's sequencing depth and analytics fall short of dedicated sequencing specialists like Reply.io, Outreach, or Salesloft when you need advanced branching logic.
If your outreach strategy depends on nuanced, multi-step conditional cadences, Reply.io's sequencing engine is the more refined tool.
AI Capabilities
Both platforms have invested heavily in AI, but with different philosophies.
Apollo's AI centers on research and personalization: Cortex AI reads prospect LinkedIn activity and company news to generate personalized opening lines, an AI Sequence Builder creates cadences from natural language prompts, and lead scoring helps prioritize outreach.
Reply.io's standout AI product is Jason, a full AI SDR agent that goes further than assistance. Jason can define your ideal customer profile, source leads in real time, write personalized messages, and handle incoming replies with limited human oversight. This is a meaningfully more autonomous product than Apollo's AI features, but it comes at a substantially higher price point, starting in the hundreds of dollars per month as a separate product.
If you want AI to assist your reps, both platforms deliver. If you want AI to run outbound largely on its own, Reply.io's Jason is the more mature offering, provided your budget supports it.
Dialer and Calling
Apollo includes a built-in power and parallel dialer with call recording, supporting calls to over 100 countries, available from the Professional tier upward. Reviewers describe it as functional but not best-in-class, noting that power-dialing teams may outgrow it within months.
Reply.io's dialer is included on the Professional plan, though minutes are billed separately through minute packs, typically running $0.02 to $0.04 per minute for US-to-US calls.
Neither platform's dialer matches dedicated calling specialists, but Apollo's inclusion of call recording and broader country coverage gives it a slight edge for teams doing meaningful outbound calling volume.
Email Deliverability and Warm-Up
Reply.io includes unlimited email warm-up starting on its entry Starter tier, which helps protect sender reputation before you start sending at volume.
Apollo discontinued its native email warm-up feature in 2024. Its replacement, called Inbox Ramp Up, paces sending volume but does not build sender reputation the way dedicated warm-up tools do. Teams running high-volume Apollo outreach often need a separate warm-up subscription to protect deliverability.
If protecting your sender reputation without adding another tool matters to you, Reply.io's built-in warm-up is a meaningful practical advantage.
CRM Integrations
Both platforms integrate with the major CRMs. Apollo offers native sync with HubSpot and Salesforce starting on the Basic tier, with more advanced sync available on Professional and above.
Reply.io gates CRM integrations (Salesforce, HubSpot, Pipedrive) behind its Professional tier, meaning Starter users do not get native CRM sync without relying on a workaround like Zapier.
If CRM sync matters from day one at the lowest price point, Apollo includes it earlier in its plan structure than Reply.io does.
Reporting and Analytics
Apollo's Professional and Organization tiers include advanced reporting, and its Organization tier adds custom reports for larger teams.
Reply.io's Ultimate tier includes the most advanced reporting and integrations in its lineup, positioned specifically for larger teams that need deeper visibility into sequence performance across channels.
Both platforms reserve their strongest analytics for their top-tier plans, so budget accordingly if reporting depth is a priority.
Pros and Cons
Apollo.io Pros
- Massive built-in contact database, removing the need for a separate data provider
- Bundles data, sequencing, dialer, and CRM sync into one subscription
- Strong free plan that is genuinely usable for early-stage teams
- Competitive per-seat entry price starting around $49/month
- High G2 rating (4.7/5 across more than 9,500 reviews)
Apollo.io Cons
- Credit system can create budget unpredictability, especially at scale
- Data accuracy drops meaningfully outside the US
- Native email warm-up was discontinued and replaced with a weaker pacing tool
- Per-seat pricing multiplies quickly across larger teams
- Advanced features like SSO and international dialing require the Organization tier's three-seat minimum
Reply.io Pros
- Best-in-class multichannel sequencing with sophisticated conditional logic
- Built-in email warm-up included from the entry tier
- Jason AI offers a genuinely autonomous AI SDR option for teams wanting to scale outbound without adding headcount
- Dedicated agency plan for multi-client outbound management
- Mature, well-refined sequence builder backed by years of iteration
Reply.io Cons
- No large native contact database, so most teams need a separate data source

- Jason AI is priced separately and can get expensive quickly
- CRM integrations gated behind Professional tier
- Overall cost adds up fast once channels, AI, and add-ons are stacked together
Real Scenarios: Which One Should You Actually Pick?
You're a startup founder just starting outbound with no contact list. Apollo.io is the clear choice here. Its free plan and built-in database mean you can start finding and reaching prospects without buying a separate data tool.
You already use a data provider like ZoomInfo and just need better sequencing. Reply.io's Professional plan gives you more sophisticated multichannel sequencing to run against contacts you're already sourcing elsewhere.
You run a small SDR team that wants to eventually reduce reliance on manual outreach. Reply.io's Jason AI is worth evaluating, though budget carefully since it is priced as a separate, higher-cost product.
You're an agency managing outbound for ten different client accounts. Reply.io's dedicated agency plan, built for centralized multi-client management, fits this workflow more directly than Apollo's structure.
Your team is under 10 reps, US-focused, and wants to consolidate tools to save money. Apollo.io's all-in-one approach, bundling data, sequencing, and a dialer, will likely cost less overall than running separate specialized tools.
Deliverability and sender reputation are a top concern because you're sending high volume. Reply.io's included email warm-up gives you a practical advantage here without needing to add another subscription.
Frequently Asked Questions
Which platform is cheaper, Apollo.io or Reply.io?
At the entry tier, both start around $49/user/month, but the real cost depends on what you need. Apollo's free plan is more usable out of the box, while Reply.io's entry Starter tier is email-only and requires upgrading to Professional (around $89/user/month) for multichannel features.
Does Apollo.io include email sequencing?
Yes. Apollo includes unlimited sequences starting on its Basic plan, covering email, LinkedIn, and phone touches, though its sequencing logic is less advanced than Reply.io's.
Does Reply.io have its own contact database?
No. Reply.io focuses on sequencing and outreach execution rather than contact discovery. Most teams pair it with a separate data source or their own existing lists.
What is Jason AI on Reply.io?
Jason is Reply.io's AI SDR agent, capable of defining your ideal customer profile, sourcing leads, writing personalized messages, and handling replies with reduced manual oversight. It is priced separately from the core sales engagement plans.
Is Apollo.io's contact data accurate?
Apollo claims high accuracy rates, but independent reviews report closer to 88% accuracy for US contacts and significantly lower accuracy, around 60 to 73%, for contacts outside North America.
Can I use both platforms together?
Some teams do exactly this: using Apollo for contact discovery and enrichment, then exporting or syncing that data into Reply.io for more sophisticated multichannel sequencing. This adds cost but combines each platform's core strength.
Which platform is better for a solo founder or freelancer?
Apollo.io's free plan and low entry price make it the more accessible starting point for a single user who needs both contacts and basic outreach tools without a large budget.
Final Verdict
Apollo.io and Reply.io solve genuinely different problems, even though they compete for the same budget line.
If your biggest challenge is finding verified contacts and you want data, sequencing, and a dialer under one roof, Apollo.io delivers more value per dollar, especially for smaller, US-focused teams just building out their outbound motion.
If you already have contacts and need the most refined multichannel sequencing engine on the market, backed by a genuinely capable AI SDR option, Reply.io is built specifically for that job.
Test both before signing an annual contract. Apollo's free plan and Reply.io's 14-day trial cost nothing to explore, and running your actual prospect list through each platform will tell you more about the right fit than any pricing page ever could.
