Apollo vs Instantly: What Does an Outbound Lead Actually Cost? (2026)

Short answer: Apollo and Instantly aren't competing products — Apollo is a contact database plus sequencer billed per seat with metered credits; Instantly is a sending infrastructure platform (unlimited mailboxes, unlimited warmup, included on every tier) billed on emails-sent and contacts-uploaded, with lead data sold as a separate product ("Instantly Credits," formerly SuperSearch). A founder using Apollo alone gets a database and a sender in one bill; a founder using Instantly alone gets a best-in-class sender with no data source, so an Instantly-only stack needs a separate list source before it can send anything. The real "cost per outbound lead" question is almost always about which combination you run, not which single platform you pick.

Pricing at a glance

Apollo.io (per-seat, annual billing): Free $0; Basic $49/user/mo; Professional $79/user/mo; Organization $119/user/mo (3-seat minimum). Includes contact database access, unlimited-ish email credits (fair-use policy), metered mobile and export credits, and a built-in sequencer with a US dialer from Professional up.

Instantly.ai — two separate subscriptions:

ProductPlanPrice/mo (annual)What it includes

Outreach (sending)Hypergrowth$77.60Unlimited mailboxes + warmup; 100,000–125,000 emails/mo (Instantly's own materials list both figures inconsistently), 25,000 contacts
Outreach (sending)Light Speed$286.30Unlimited mailboxes + warmup; 500,000 emails/mo, 100,000 contacts
Instantly Credits (lead data)Nano/Growth/Hyper tiers~$42–$197/moSeparate B2B contact database (450M+ records), sold independently of Outreach

Instantly does not charge per mailbox or per seat on Outreach — this is its core structural difference from Apollo.

What the headline price excludes

  • Apollo's per-seat price already includes a sender, but Apollo doesn't provide the mailbox either. Like Instantly, Apollo sends through mailboxes you connect (Google Workspace, Microsoft 365, or SMTP) — Apollo just isn't built with the same unlimited-mailbox, dedicated-warmup architecture Instantly uses for high-volume cold outbound. Any real cost comparison needs to add mailbox/domain costs to both platforms, not just one.
  • Instantly's "unlimited mailboxes" doesn't mean free mailboxes. Instantly doesn't sell or include the actual mailbox/domain — those are provisioned and paid for separately (Google Workspace, Microsoft 365, or a cold-email-specific mailbox provider), typically $3–$6/mailbox/month plus a domain (~$10–$15/year each).
  • Instantly's list is empty until you buy data. Instantly Credits is a wholly separate subscription from Outreach; a solo founder on Instantly Growth ($37.60/mo) has a sending engine with nothing to send to until they add a data source (Instantly Credits, Apollo, or manual list-building).
  • Apollo's export credits are the real ceiling on volume, not its per-seat price — a team on Basic (1,000 export credits/month) can only pull 1,000 contacts a month out to a sender, Apollo's own or otherwise.

Hidden costs to model before you buy

  • Mailbox and domain costs are the largest external line item for any real outbound program, regardless of which sending platform you use. A rule of thumb used across the industry: roughly 3 mailboxes per sending domain, sending 20–30 emails/day/mailbox to protect deliverability.
  • Instantly's Hypergrowth send-volume figure is inconsistently stated across Instantly's own materials (100,000 on the yearly pricing card vs. 125,000 on the monthly card and pricing file) — plan around the lower, more conservative figure.
  • Apollo's mobile credits are the tightest constraint for teams that call, not just email — at 75–100 credits/month on Basic/Professional, a team making outbound calls will exhaust mobile credits well before export or email credits.
  • Neither platform's subscription price includes email verification. A clean list before sending typically needs a separate verification pass (bounce-rate protection), an added per-contact cost outside both platforms' base pricing.

Worked scenarios

We normalize to cost per 1,000 prospects contacted and flag every conversion-rate assumption explicitly rather than presenting it as a platform fact.

Scenario A — Solo founder outbound

Both platforms need real, connected mailboxes to send from — we assume a modest 2 mailboxes on 1 domain for either platform at this scale (~$10/mo mailboxes + ~$1/mo domain ≈ $11/mo infrastructure), applied identically to both, so the comparison isolates the platform-subscription difference rather than hiding an infrastructure cost on one side only.

  • Apollo only (Basic, 1 seat, $49/mo) + infrastructure (~$11/mo): at ~1,000 export credits/month, this comfortably covers a founder-scale list from a single platform that also supplies the data. Total: ≈$60/month.
  • Instantly only (Growth Outreach, $37.60/mo + Nano Credits, ~$42/mo + infrastructure, ~$11/mo): Total: ≈$90.60/month, buying dramatically more sending headroom (unlimited mailboxes, dedicated warmup) than a founder needs yet, at the cost of running two subscriptions instead of one.
  • At solo-founder volume, Apollo's single-subscription model is cheaper on a fully-loaded, apples-to-apples basis; Instantly's scale advantage isn't yet needed.

Scenario B — 5-person sales team

We apply the same mailbox/domain assumption to both platforms: 5 reps × 3 mailboxes each = 15 mailboxes, on roughly 5 domains (1 domain per 3 mailboxes) → 15 × $5 + 5 × $1 = $80/month infrastructure, added to both.

  • Apollo Professional (5 seats, $395/mo annual) + infrastructure (~$80/mo): mobile credits (500/month across 5 seats) and export credits (10,000/month across 5 seats) become real constraints at this team size — a team calling and exporting heavily will hit overage on top of this. Total: ≈$475/month.
  • Instantly Hypergrowth Outreach ($77.60/mo) + Hyper Credits (~$197/mo) + infrastructure (~$80/mo): Total: ≈$354.60/month, for a much higher email-sending ceiling (100,000+ emails/month) than Apollo's sequencer is built to handle.
  • Once infrastructure is applied symmetrically, Instantly's combined stack is meaningfully cheaper than Apollo's at this team size — not just higher-capacity, but lower total cost — because Apollo's per-seat pricing multiplies faster than Instantly's flat platform fee plus a separate data subscription.

Scenario C — High-volume outbound operation (10+ reps, agency-scale)

Same symmetric assumption, scaled up: 10 reps × 5 mailboxes each (agencies typically run more mailboxes per rep at this scale) = 50 mailboxes on roughly 17 domains → 50 × $5 + 17 × $1 = ≈$267/month infrastructure, added to both.

  • Apollo Organization (10 seats, 3-seat minimum already exceeded, $1,190/mo annual) + infrastructure (~$267/mo): 2,000 mobile + 40,000 export credits/month total — likely still insufficient at true high volume, requiring overage purchases on top of this. Total: ≈$1,457/month.
  • Instantly Light Speed ($286.30/mo) + Hyper/Enterprise Credits (~$197–custom) + infrastructure (~$267/mo): Total: ≈$750.30/month or more (the credits line is custom-quoted above the Hyper tier, so this is a floor, not a ceiling), for up to 500,000 emails/month — a ceiling Apollo's sequencer isn't designed to reach at all.
  • At this scale, once infrastructure is counted identically for both, Instantly's stack costs roughly half of Apollo's while supporting far higher volume — Apollo's per-seat, credit-metered model is both more expensive and more constrained here, and most agencies at this scale pair Instantly (or Smartlead) with a separate data source rather than relying on Apollo's sequencer.

Break-even: when does adding a second subscription pay off?

Once mailbox and domain infrastructure is counted the same way for both platforms, Apollo's per-seat pricing is the variable that erodes its cost advantage as team size grows — the crossover in these scenarios falls somewhere between the solo-founder case (Apollo cheaper) and the 5-person case (Instantly cheaper), meaning most teams beyond roughly 2–3 seats will find a two-subscription Instantly-plus-data-source stack cheaper on a like-for-like basis, not just higher-capacity.

Who pays more — and when the answer flips

At solo-founder scale, Apollo's single-subscription model is genuinely cheaper once infrastructure is counted for both. Past a small team size, Apollo's per-seat pricing compounds faster than Instantly's flat platform fee plus a separate data subscription, so a two-subscription Instantly stack becomes both cheaper and higher-capacity at the same time in the scenarios modeled here — the "Instantly costs more because it's two subscriptions" intuition doesn't hold once mailbox/domain costs are applied consistently to Apollo as well. Cost per positive reply still depends entirely on list quality and messaging, neither of which either platform's pricing page can tell you — do not treat an assumed reply rate as a vendor-provided fact when budgeting either stack.

For contact enrichment and qualification, see Clay vs Apollo's cost-per-qualified-lead comparison. If you are comparing sending capacity rather than lead sourcing, Instantly vs Smartlead vs Lemlist separates platform fees from mailbox infrastructure. Sales teams evaluating rep productivity can also compare Gong vs Salesloft's per-rep economics.

Limitations and uncertainty

  • Instantly's own pricing materials give two different figures for Hypergrowth's monthly email ceiling (100,000 vs. 125,000); we used the lower, more conservative figure where it mattered for scenario math and flagged the discrepancy explicitly.
  • Mailbox and domain cost estimates ($3–$6/mailbox/month, ~$10–$15/year/domain) are industry-typical figures from cold-email infrastructure providers, not prices quoted by Apollo or Instantly themselves.
  • Apollo's exact credit allocations per tier vary somewhat across independent trackers; we used the most commonly repeated figures.
  • No reply-rate or conversion assumption in this article should be read as a benchmark — they exist solely to illustrate the calculation method, and real reply rates vary enormously by list quality, offer, and industry.
