Apollo.io vs Outreach: Cross-Category Comparison

Apollo's plan cards list Unlimited Sequences from the $49 Basic tier upward, so the sending side stops scaling at the first paid step while the credit grant keeps climbing from 30,000 to 72,000 per seat per year. The ladder reads like a features ladder and prices data. Outreach sits on the other side of that line and names no price on its own pricing page, only four Amplify packages and an AI credit allowance. Reading those two shapes together is what an Apollo vs Outreach.io comparison is for, and one detail has moved since most of them were written: every www.outreach.io address now redirects to www.outreach.ai, so the ".io" in the search is the vendor's old domain. What follows prices both shelves from their own published figures and answers whether Outreach earns a second line on the invoice at all.

Apollo vs Outreach.io: Which One Do You Need?

These two are filed in different categories and they are not substitutes, though the overlap is wider than the labels suggest. Apollo is a contact database with a sequencer, a dialer and a deliverability suite attached, priced per seat with a credit grant. Outreach is a sales engagement platform that runs sequences, calls, coaching and forecasting on top of a CRM and a data source it does not own. A team buys Apollo first when the list is the constraint, because it can be priced and started from its own page in an afternoon. Most teams that run Outreach still run a data source beside it, and Apollo's compare table lists an "Outreach & SalesLoft Integration" from Basic upward, which is what connects the two when both are in the stack.

Apollo's own sales engagement page answers the question directly, in its FAQ "How is Apollo different from Outreach or Salesloft?": "Standalone engagement platforms handle outreach but rely on separate data and dialer tools, adding cost and context loss." That is a vendor's claim about its rival, so read it as Apollo's position and no more. Outreach's pricing page makes the opposite bet in its own words: "Teams can scale AI usage across different workflows without being limited by seat-based pricing alone."

What Each Side Actually Does in a Cold Outbound Run

A cold outbound run has a fixed shape, and this pair straddles it in a way the category labels hide. Targeting comes first, and that is a decision about who is worth writing to rather than a piece of software. Then the list gets built and a mailbox gets resolved for every person on it, which is squarely Apollo.io's half: search filters, an extension over a profile, a spreadsheet pushed back through enrichment, and a verification pass that discards anything the provider could not confirm. Apollo's site describes its data product as "240M contacts & 30M companies" in the product menu of the pricing page itself.

Sending is where the line blurs. Outreach owns sender accounts, sending windows, reply detection and the record of who answered, and Apollo.io ships unlimited sequences and a deliverability suite with email warmup of its own. The honest question here is whether that included sender is enough for the wave being planned, and Apollo's own compare table answers part of it: on Free and Basic the platform allows "1 mailbox per user" and "250 emails" a day, and only Professional lifts that to "Unlimited Google and Microsoft mailboxes + 5 SMTP mailboxes per user" with unlimited daily sends. RevenueFlow runs one message per campaign either way, so nothing on that side is a bump step or a thread reply waiting to fire. A prospect who stays quiet gets re-approached later in a new campaign with a different angle, never with a second message stacked under the one they ignored, and on LinkedIn that second message does not get sent at all.

The last stage belongs to neither product. Somebody reads the reply and somebody books the meeting, and the meeting counts only against qualification criteria written down before the campaign launched.

Pricing Comparison

Apollo.io Pricing

Every paid price above is the per seat per month rate billed annually, read with the page's "Annual billing Save 24%" toggle in its default state, and the Organization card reads "(min 3 seats)". The credit rates below the cards are the second part of the bill: "Email 1 credit", "Phone number 8 credits", "Enrich data 1-8 credits" and "US Dialer 2 credits per minute".

Outreach Pricing

Outreach sets out on the same page that "Outreach uses a combination of seat-based pricing and consumption-based pricing powered by AI credits." Its FAQ explains that consumption is "measured based on discrete actions" and that "you can purchase additional credit packs at any time".

Reading the Two Price Shapes Together

Apollo's plan cards publish a per seat per month rate billed annually: Basic at $49, Professional at $79 and Organization at $119, with a three seat minimum on Organization. What moves up that ladder is the interesting part. Sending stops scaling immediately, since the free plan lists "2 Sequences" and every paid tier from Basic upward lists "Unlimited Sequences", while the credit grant climbs the whole way, from 900 credits per seat per year on Free to 30,000, 48,000 and 72,000 granted upfront. The one sending limit that does move is the mailbox count, which lifts at Professional. On Apollo's own page the tier decision is a data decision with a mailbox rider.

Outreach publishes packages and no prices on that page. It lists Amplify Essentials, Core, Plus and Pro, each behind a Request pricing button. The credit allowance is the one public number: 10,000 on Essentials, 25,000 on Core, 50,000 on Plus and 100,000 on Pro. Seat count and AI usage therefore move a quote independently, and "Multi-Channel Engagement & Sequences" is listed from Core up, so the entry package is the conversation intelligence one.

Those are two different kinds of number and they do not compare directly. Apollo.io publishes a rate a team can multiply out before speaking to anybody; Outreach publishes a shape and produces the rate on a call. Half of this stack can be budgeted today and half cannot, so a plan treating the Outreach line as an estimate is guessing at the larger of the two numbers.

What One Year of This Stack Actually Costs

Take an invented but ordinary case: two people running outbound, each wanting to send from more than one mailbox. The rates below are Apollo's own published figures; the team and the seat count are invented to make the arithmetic concrete.

Apollo Basic at $49 per seat per month billed annually is $1,176 a year for two seats and grants 60,000 credits across them, but it holds each seat to one mailbox and 250 sends a day. Apollo Professional at $79 is $1,896 a year for 96,000 credits, so the step costs $720 and buys 36,000 extra credits, which is $0.02 a credit, plus unlimited Google and Microsoft mailboxes and unlimited daily sends. For this team the step is a sending decision as much as a data one. Apollo Organization at $119 cannot be bought for two people at all, because the card carries a three seat minimum, so its real number for this team is $4,284 a year for three seats.

Line, two seats, twelve months	Per year	Credits	Sending limit on the tier
Apollo Basic, $49 a seat	$1,176	60,000	1 mailbox per user, 250 emails a day
Apollo Professional, $79 a seat	$1,896	96,000	Unlimited mailboxes and sends
Apollo Organization, $119, three-seat minimum	$4,284	216,000	Unlimited, + 15 SMTP mailboxes per user
Outreach Amplify Core, the first package with sequences	quote	25,000 AI	not published

The Outreach side of that year cannot be added, which is the finding rather than a gap in the research. Outreach's pricing page carries four packages and a Request pricing button on each, so any figure in a plan for it is a placeholder until a quote lands.

What Each Vendor's Pages List

Apollo's pricing page groups its plan contents under four headings, Outbound, Inbound, Data enrichment and Deal execution, and the compare table under them lists sequences with A/Z testing, an AI writing allowance from 5,000 to 1,000,000 words a month, a dialer, "Call Recordings & AI Insights", "Meeting Scheduler", "Waterfall Enrichment", "CRM Integrations (Salesforce, HubSpot, Pipedrive)" and the "Outreach & SalesLoft Integration".

Outreach's pricing page lists, by package, "Multi-Channel Engagement & Sequences", "Meeting Scheduling & Tasks", "Outreach Voice Integrated Dialer", "Real-Time Transcription", "Deal Management", "Pipeline Management", "Data Enrichment" on every package and, on Pro, "AI Forecast Projection" and a "Forecasting Scenario Planner".

Both lists are the vendors' own wording, so the honest reading is that Apollo.io lists these capabilities and Outreach lists those. A feature named on a plan card is a claim about scope rather than a measure of quality, and a line missing from one page is not evidence that the product lacks it. Outreach listing data enrichment on every package is why the overlap runs in both directions: the useful question is which product a team wants to be the source of record for a contact.

When to Choose Which

Read the split as a question about which gap is open rather than about which product is better. Apollo.io answers a sourcing question first and a sending one second, and Outreach answers a workflow question, so a team that names the wrong gap buys a capable tool that changes nothing.

Choose Apollo.io when the list runs out before the quarter does, when the team has no sending tool at all and the mailbox limit on Basic fits, or when a published price has to go into a budget this week. Choose Outreach when meetings are being booked and lost to disorganised follow-through, when sequencing has to run across a whole sales org with coaching and forecasting on the same record, or when a data source already exists and the gap is orchestration rather than contacts.

Do You Need Both, and in Which Order?

Most teams reading this page do not need both yet. Apollo.io lists unlimited sequences and a deliverability suite with email warmup from Basic, which is enough to run a first wave and find out whether the list is the problem, as long as one mailbox and 250 sends a day per seat fit the wave. Buying Outreach alongside it in the same month buys a better sending experience before anyone knows whether sending is what is failing.

The order that works is data first, sending second, for reasons of measurement rather than preference. A sending platform bought onto a thin list delivers that list faster and its reporting will blame the quiet quarter on copy. A list deep enough to keep a wave fed shows its problems within one campaign, and those problems are the brief for the sending purchase.

One case honestly reverses it. A team already booking meetings and losing them to disorganised follow-through has a workflow gap rather than a data gap. Outreach's packages are built around deal and pipeline management, coaching and forecasting rather than around first touches, territory a revenue AI tool like Gong also sells into, and that is the gap they price.

Whichever way round, the two connect through the CRM and through Apollo's own listed Outreach integration, and that is the surface to test during a trial rather than after one. A handoff needing a CSV in the middle is a handoff somebody stops doing in week three. The same pair filed the other way round, with Apollo as the sequencer, is on Apollo.io vs Outreach as sales engagement platforms.

Using Both Together

Start with Apollo, because it is the half a team can buy and use in an afternoon and the half that tells you whether the target list exists. Run one wave on Basic, count how many of the accounts that matter come back with a verified mailbox, and only then decide whether the sending side needs its own product. Outreach lands second in almost every case, because its quote scales with seats and AI usage together and neither number is knowable until a wave has actually run.

Whichever order the two arrive in, keep the sending inventory out of it. Sender domains, mailbox warmup and daily caps are their own project, and a stack change made in the same week as a sending change leaves nothing to attribute a bounce rate to. Change one layer, let a full wave run, then change the next.

Two habits save real money. Trial on accounts already worked rather than on a fresh list, because the only coverage question that matters is coverage on the segment being sold to. And export what the incumbent already found before a subscription lapses: records bought once are cheap to keep and expensive to buy twice.

The Short Version

• Apollo.io can be priced from its own page today, starting at $49 a seat a month on annual billing, with one mailbox and 250 sends a day per seat until Professional.
• Outreach names no price on its own pricing page, so the Outreach line in any budget is a quote until a call happens, and the page now lives at outreach.ai.
• Apollo.io lists unlimited sequences and a deliverability suite with email warmup from Basic, so a first wave can run without buying Outreach at the same time.
• Buy the data side first when the list runs out, and the workflow side first when meetings are being lost after the reply.
• Measure the change in meetings booked against criteria fixed before launch, because that is the only number both products are trying to move.
