Reply.io vs Apollo.io

Apollo.io fits teams wanting data and sequencing in one subscription; Reply.io fits teams that bring their own data and go multichannel. Both run multi-step outbound sequences, track replies and log activity to Salesforce or HubSpot, and on that surface they are closer than either vendor's marketing suggests. The real difference is whether contact data is the product. Apollo is a B2B database that added engagement on top, sold per user per month with published prices. Reply.io is a sequencing and multichannel execution platform that treats data as optional, sold on two different meters depending on the plan you pick.

That structure is worth understanding before any demo. Apollo charges per seat, then again for credits, where a verified email is 1 credit and third-party breakdowns report 8 credits for a mobile number. Reply.io's Email Volume plan charges by active contacts from 1,000 a month with unlimited users, while its Multichannel plan charges per user and includes a LinkedIn account plus calls and SMS in each seat. So Apollo's bill tracks headcount and data consumption, and Reply's tracks either list size or headcount depending on which plan fits the motion.

The buying situation for Apollo is a founder-led or small outbound team with no data contract, where one bill and one support line matter more than channel breadth. The buying situation for Reply.io is a mid-market SDR team that already trusts a data vendor and runs sequences across email, LinkedIn and phone, with a manager or RevOps generalist administering it part time. If email is your only channel and you already own data, run the comparison on deliverability and admin burden rather than on feature lists.

Reply.io fits mid-market SDR teams that want multichannel sequences running quickly, with a manager or RevOps generalist administering it part time.

Channels are modular. Reply lists LinkedIn automation at $69 per account per month and calls and SMS at $29 per user per month as add-ons, with website visitor reveals and optional live data credits on top (checked September 2026 on reply.io).

Where Reply.io wins: multichannel steps and agency-style flexibility. LinkedIn, calls, and SMS sit in the same sequence as email, and teams can keep using the data vendor they already trust.

Two pricing meters mean one usually fits better than a per-seat model. Email Volume starts at $59 a month priced by active contacts (from 1,000) with unlimited users, which suits a small team sending to a large list. Multichannel starts at $99 per user per month. Agency is from $166 a month with client workspaces, and AI SDR (Jason AI) from $500 a month (checked September 2026 on reply.io).

For a 10-rep team the modular route is rarely the cheap one: Multichannel at the starting price is 10 x $99 x 12 = $11,880 a year, while running Email Volume plus LinkedIn and calling add-ons for each rep adds 10 x ($69 + $29) x 12 = $11,760 on top of the base, so Multichannel usually wins once reps need more than email.

Who it fits best: teams with a data source they trust that want more channels than email, and agencies that need separate client workspaces on one contract.

Apollo.io fits founders and small outbound teams that want to find contacts, filter them, and sequence them without switching tools. G2 reviewers praise its search filters and data accuracy.

It reduces stack cost for early teams because data and sending sit on one bill, and it removes the procurement work of negotiating a data contract separately from a sequencing contract.

Where Apollo wins: one tool for list building and sending. For a small team, not needing a separate data contract often matters more than extra channels.

Data and sending sit on one contract, which removes a whole class of integration work: no list export, no field mapping between a data vendor and a sequencer, and one place to look when a campaign underperforms.

Pricing: Apollo lists Free, Basic at $49, Professional at $79, and Organization at $119 per user per month billed annually ($59, $99, and $149 monthly; Organization needs 3 users). A 10-seat team on Professional pays 10 x $79 x 12 = $9,480 a year, or $5,880 on Basic and $14,280 on Organization, before extra credits (checked September 2026 on apollo.io).

Who it fits best: prospecting-first teams in markets where Apollo's data coverage is good, and teams without an ops person to run two vendors.

Compare total cost at full headcount, not plan against plan. Ten reps on Apollo Professional is $9,480 a year with data included; ten reps on Reply.io Multichannel is $11,880 plus whatever your data contract costs, which is often another $10,000 or more. Apollo looks cheaper on that line, so the question becomes whether its data covers your market well enough to be the only source.

Reply.io's extras add up quietly. AI and live data credits are sold in packs from 200 to 10,000 a month, email validation is a separate subscription, extra mailboxes are $29 each per month on Multichannel, and new sending domains start at $6 a year plus $5 per mailbox per month, or $25 plus $15 for pre-warmed. Some features are marked as annual-plan only, so confirm what a starting price assumes.

Check what already overlaps in your stack. If you run a dialer, a LinkedIn tool and a data vendor today, Reply.io's Multichannel seat may replace two of them, while Apollo may replace the data contract but not the dialer you prefer. Governance needs also grow with team size, so test template control, permissions and cross-pod reporting in both if more than one team will use it.

Deliverability is where outbound programs actually fail. Volume sending is a known limit for Apollo, and warm-up and mailbox management are ongoing work in Reply. Ask each vendor how they handle bounces, unsubscribes and daily send limits per mailbox, and check data coverage yourself by pulling 30 contacts from your own ICP in Apollo and verifying emails and titles, especially outside North America.

Staying put is a real option. If reply rates are low because the list or the message is wrong, a new sender changes nothing. When you do move, sequences and templates rebuild quickly but reply and activity history may not: export sequence stats, confirm how CRM activity is de-duplicated while both tools run, and pilot by sending the same sequence to matched segments from each tool for three weeks on separate warmed mailboxes, comparing bounce rate, reply rate and meetings booked per 100 contacts.

Neither shortlist survives a demo unchanged, so write down the one workflow that has to work before you take the call. Our research and ranking method explains how we weigh these trade-offs.
