After checking both vendors’ pricing pages, help centre documentation and partner programmes against the six things agencies actually get caught by, Instantly and Apollo come out ahead for different jobs. Instantly is the better core tool for an agency sending cold email at volume, because it bills per workspace rather than per seat, while Apollo is the better buy for teams whose bottleneck is working out who to contact rather than reaching them.
Below, I have compared both tools on pricing, agency and client handling, deliverability, lead data, sequencing and support, so you can see which side of that split you fall on. There is also a third answer most instantly vs apollo comparisons raise and never cost out, which is running both.
Key Takeaways
- Instantly bills per workspace, Apollo bills per seat. That decides most agency comparisons before any feature does.
- Instantly’s entry cost is $47/month month-to-month, or $37.60 billed annually, and it buys sending only: leads and CRM cost extra.
- Apollo starts at $59/user/month month-to-month ($49 billed annually) and every tier includes the full product, though Organization has a 3-seat minimum.
- Instantly’s flat fee stops being flat at the client level. True separation means one paid workspace per client, since portal access exposes every campaign in it.
- Apollo does run an agency programme, contrary to what several ranking comparisons claim, though its client separation is much less documented.
- Running both is a real option, and a maintained Zapier bridge connects them: source in Apollo, send in Instantly.
Why should you trust us? Our research methodology
Across the articles currently ranking for this comparison, Instantly’s entry plan is quoted at $30, $37, $37.60 and $47, and Apollo’s Organization tier at both $119 and $149 per seat. All of them are published as though they were the price. The reason is mundane: some sources quote month-to-month rates and others the annual-billed equivalent, without labelling either.
So every figure here was checked at source. Prices and plan inclusions come from instantly.ai/pricing and apollo.io/pricing, verified on 3 August 2026, with both billing periods stated wherever they differ. Feature mechanics come from each vendor’s own help centre rather than its marketing pages, agency capability from their published partner programmes, and user sentiment from Trustpilot, Capterra and G2 reviewers.
Instacopy.ai sells no cold email sending platform, sequencer or lead database, and has no commercial relationship with either tool here. Almost every other article ranking for this comparison is published by a company selling a competing product or service.
How Do Instantly and Apollo Compare?
Instantly is a sending platform built to push volume through many mailboxes at once: unlimited inboxes, unlimited warmup. Apollo is a database with sequencing, a dialer and a CRM attached, built to find people and work them across channels. Comparing the headline prices sets a fraction of one product against the whole of the other, which is why they never reconcile.
| Feature | Instantly | Apollo |
|---|---|---|
| Best for | Email-first sending at volume, agencies | Full-stack sales teams, prospecting-led outbound |
| Pricing model | Flat fee per workspace | Per seat |
| Entry price | $47/mo monthly, $37.60/mo annual (sending only) | $59/user/mo monthly, $49/user/mo annual |
| Entry price includes | Sending and warmup only; leads and CRM extra | Database, sequencing, enrichment, deal execution |
| Email accounts | Unlimited on every tier | Tied to seats |
| Lead database | 450M+ contacts, waterfall across 7 providers | ~275M contacts, one proprietary index (third-party estimate) |
| Email warmup | Unlimited, on every tier | Inbox Ramp-up and Email Warmup, on select plans |
| Channels | Email only | Email, LinkedIn tasks, calling via dialer |
| Agencies and clients | White-label portals from Hypergrowth up, one per workspace | Solutions Partner programme with client sub-accounts |
| Free tier | No free plan | Free plan, 900 credits per seat per year |
1. Pricing: What Do Instantly and Apollo Really Cost?
Instantly is cheaper for agencies running many inboxes across few people, and Apollo is cheaper for small teams who need a database more than they need send volume. The winner depends on the shape of your operation, not its size.
Both numbers in each pair below are real; only the billing period differs.
What Instantly costs
| Plan | Monthly billing | Annual billing | Emails/month | Contacts | Notes |
|---|---|---|---|---|---|
| Growth | $47/mo | $37.60/mo | 5,000 | 1,000 | Unlimited email accounts and warmup |
| Hypergrowth | $97/mo | $77.60/mo | 125,000 | 25,000 | White-label client portals, conditional subsequences |
| Lightspeed | $358/mo | $286.30/mo | 500,000+ | 100,000+ | Adds SISR server and IP rotation |
| Enterprise | Custom | Custom | 500,000+ minimum | Custom | Private deliverability network, dedicated account manager |
That table covers sending only. Instantly’s lead database is a second subscription, and it is where budgets break:
- Growth Credits: $47/month for 1,500 credits
- Supersonic Credits: $97/month for 5,000 to 7,500 credits
- Hyper Credits: from $197/month for 10,000 to 200,000 credits
The CRM is a third purchase again, so a small agency running sending plus lead data realistically pays $200 to $400 a month, not the headline sending price. A bundled Starter plan at $94/month ($85/month billed annually) covers sending, 1,500 credits and SuperSearch access in one line item, which is why quoted totals vary so much depending on which page a buyer lands on.
What Apollo costs
| Plan | Monthly billing | Annual billing | Credits per seat/year | Notes |
|---|---|---|---|---|
| Free | $0 | $0 | 900 | No card required |
| Basic | $59/user | $49/user | 30,000 | Full product access |
| Professional | $99/user | $79/user | 48,000 | Adds dialer and A/B testing |
| Organization | $149/user | $119/user | 72,000 | 3-seat minimum, a $357 to $447/month floor |
Apollo grants those credits upfront each year and spends them per action:
- 1 credit per email address found
- 8 credits per phone number
- 2 credits per minute on the US dialer
- 1 credit per AI research run
Credits are reported by users to expire each cycle rather than rolling over, and Apollo does not publish a rollover policy on its pricing page, so treat seasonal prospecting as a use-it-or-lose-it budget.
Here is the crossover. A three-person agency running 30 inboxes for four separated clients pays Instantly for workspaces and Apollo for seats, so the arithmetic flips on whichever number grows. Add inboxes while headcount holds steady and Instantly wins by a distance. Add people and Apollo’s per-seat bill climbs fast, though every seat also carries the database Instantly bills separately.
2. Agencies and Clients: Which One Actually Handles Multiple Accounts?
Instantly wins this round, but not as cheaply as its flat-fee reputation suggests. The mechanics that decide it sit in Instantly’s help centre and almost never reach a comparison table.
What a client workspace really costs
White-labelling requires Hypergrowth or above, so the entry Growth plan is out for any agency that wants branded client access. Then comes the part nobody documents: only one agency portal exists per workspace, and a client granted access to that portal sees every campaign running in it. There is no selective, per-client campaign visibility.
Clean separation therefore means one paid workspace per client, not one account with client folders. At Hypergrowth, four separated clients means four subscriptions. The fee is flat per workspace, not flat per agency, and one G2 reviewer put it plainly: it costs extra to add another workspace for clients.
What a client can see through the portal:
- Campaigns, with view or edit rights
- Unibox
- Analytics
- CRM
- Blocklist
Clients do not need their own Instantly subscription to use any of that, which is the genuine win.
What happens when you offboard a client
Every agency asks this and no comparison answers it. Instantly’s cancellation rules are specific and asymmetric:
- Cancel your only active plan and it runs to the end of the billing cycle, after which accounts, warmup and campaigns pause automatically
- Cancel one of several active subscriptions and it ends immediately instead
- For done-for-you pre-warmed accounts, cancellation is immediate, and Unibox conversation history is deleted after a 24-hour grace period
- A done-for-you domain stays valid for a year from purchase but expires early if every account on it is cancelled
Export reply history before you cancel, not after. A 24-hour window is not enough time to discover the rule and then act on it.
Does Apollo do agencies at all?
Several ranking comparisons state that Apollo has no agency functionality. That is wrong. Apollo publishes a Solutions Partner programme with four tiers and 20% lifetime commission on referred accounts, and its partner pages describe creating and managing client sub-accounts.
Be precise about what that is. It is a referral and reseller structure with some sub-account capability, not a documented white-label multi-tenant model of the kind Instantly ships. Apollo publishes no tenant-level detail on how one agency client’s data is separated from another’s, which is itself the answer for anyone who needs that guarantee in writing.
Instantly is the only one of the two with a documented white-label client portal, so if client-facing branding matters the round ends there. The single reason to look at Apollo instead: a team working many accounts under your own name, where per-seat billing can undercut four separate Instantly workspaces.
3. Deliverability and Warmup: Which One Protects Your Domains?
Instantly wins on deliverability infrastructure, and the gap is structural rather than marginal. Warmup is unlimited and included on every tier, inbox count is unlimited, and the Lightspeed plan adds SISR, a server and IP sharding system that distributes sending across private IP pools and rotates automatically away from any IP whose reputation drops.
Infrastructure is not the same as outcome. The only concrete user-reported deliverability number on either side comes from a G2 reviewer describing an Instantly send in which 244 of 300 emails landed in spam, on a 21% open rate. One report is not a pattern, but it is the only hard number available and it sits awkwardly against the positioning.
Apollo’s warmup is not gone, it is split in two
Apollo retired its original peer-to-peer warmup pool in 2024, which is where the “Apollo has no warmup” claim comes from. As of August 2026, Apollo’s own knowledge base documents two separate live features:
- Inbox Ramp-up paces sending volume upward for a mailbox that already has send history
- Email Warmup connects a new mailbox to third-party provider networks that generate engagement to build sender reputation
Both are gated to select plans, which Apollo does not enumerate anywhere in its documentation, so confirm inclusion with sales before you buy on the strength of either feature.
The operational settings tell you more than the feature names do. Apollo recommends a minimum two-week ramp, 10 to 40 emails per mailbox per day with a hard cap of 50, and a target reply rate of 30% daily against a 45% ceiling, using a Progressive, Flat or Randomized strategy.
Read those numbers as a spec. They describe a tool for protecting a handful of mailboxes, not for bringing forty online at once. An agency sending at volume will outgrow that ceiling whether or not the feature exists, which is the real answer to “does Apollo have warmup”.
Best for: anyone running more than a handful of mailboxes should default to Instantly, and the Lightspeed IP rotation is the reason to consider the top tier rather than just the volume allowance.
Skip this question if: you send from one or two mailboxes at modest volume, where either tool’s pacing is adequate and list quality decides inbox placement anyway.
4. Lead Data: Is 450 Million Contacts Better Than 275 Million?
Apollo wins on targeting depth, and Instantly wins on resolving a specific contact you have already identified. The two headline counts do not measure the same thing, so the bigger one is not the better database.
Instantly’s 450M+ figure describes the reach of a waterfall. A SuperSearch query checks Instantly’s own data first, and if that fails it passes down a chain of at least seven third-party providers, stopping at the first verified match. Instantly names them: BetterContact, ContactOut, Findymail, IcyPeas, LeadMagic, Prospeo and Wiza. That is reach across rented indexes, not one company’s verified database.
The chain changes your running cost, so the credit rules matter:
- 1 credit when Instantly’s own data resolves the contact
- 2 or more credits when a chained partner supplies it, and 4 specifically for a ContactOut result
- No credit at all when the whole chain runs dry and no verified email is found
That last rule is good design, and rare enough in this category to be worth saying so.
Apollo’s number describes something different: a single proprietary index, most commonly cited at around 275 million contacts, with filtering depth Instantly does not attempt. Intent signals, technographics, headcount bands, funding stage and hiring signals all live in the same query builder. That 275 million is a third-party estimate rather than a published figure, since Apollo’s pricing page states no database size at all.
Neither database is clean, and the reviewers are blunt about it. One G2 reviewer reports that a big portion of Apollo’s “verified” emails still bounce. Another says Instantly’s lead finder is geared for the US market rather than the UK. Instantly publishes no bounce-rate figure behind its claim that waterfall enrichment produces fewer bounces, so the accuracy argument rests on mechanism rather than measured output.
For a known account list, either tool will find the addresses and the credit maths decides it. Working out who to target in the first place is Apollo’s actual job, and Instantly does not really attempt it.
5. Sequences, Channels and AI: What Can Each One Actually Send?
Apollo wins on channel breadth, Instantly wins on email depth, and for an email-only agency that makes Instantly the better tool despite the shorter feature list.
Apollo runs email, LinkedIn tasks and calling inside a single sequence, and its January 2026 dialer add-on brought power and parallel modes, international dialing with local presence, call transcripts and manager-facing call visibility. Apollo’s own marketing claims reps make up to 2.5 times more calls with it, a vendor figure with no independent test behind it. More interesting is Apollo’s official MCP server, which plugs the platform into Claude, ChatGPT, Cursor and similar tools and includes a sequence skill that drafts outreach from a prompt or an ICP description.
Instantly goes deeper on the one channel it has. Conditional subsequences branch a follow-up on a lead’s status (Interested, Not Interested, Out of Office, Wrong Person) or on keywords in the reply itself, and they run on Hypergrowth and Lightspeed only. An agency sitting on Growth does not get them. The AI Sales Agent and AI Inbox Manager handle reply triage, which is the workload that actually drowns agency inboxes.
One usability difference is worth carrying into a buying decision: personalization variables in Instantly must exist as columns in the list you import and cannot be added afterwards. Apollo supports basic, custom and conditional variables plus an AI-generated opener, though a G2 reviewer found its custom variables confusing to set up.
Buy Apollo if calls and LinkedIn touches belong in the sequence, because the round is not close. For an email-only agency, Instantly’s branching and reply handling matter more than channels you will never switch on.
6. Reviews and Support: What Do Paying Customers Complain About?
Neither tool wins this round cleanly, and on both sides the complaints cluster around billing rather than product quality. That pattern is more useful than any star rating.
Apollo’s Trustpilot aggregate stood at 3.1 out of 5 across 1,230 reviews in early August 2026, and its Capterra aggregate at 4.5 out of 5 across 398 reviews, with sub-scores of 4.5 for ease of use and 4.2 for customer service. Instantly does not produce a comparable aggregate on those platforms, and the G2 figures circulating for it disagree with each other by thousands of reviews. Treat any single Instantly rating you see cited with suspicion and read the recent reviews directly instead.
What reviewers actually complain about:
- Instantly: being billed after cancelling, losing dashboard and lead access immediately on cancellation, enrichment credits becoming unusable once the related subscription lapses, and slow live chat when something is broken
- Apollo: data accuracy, constant in-product upgrade prompting, confusing pricing when buying additional credits, and support that answers a problem by recommending a higher plan
Read those two lists side by side and the same shape appears twice. Both are subscription-mechanics complaints, and both hit agencies harder than they hit a single user, because an agency is cancelling, re-provisioning and re-buying credits every time a client cycles. A solo operator meets these edges once a year. An agency with quarterly client turnover meets them constantly, which makes the cancellation rules in Round 2 a procurement question rather than a footnote.
Should You Just Run Both?
For an agency doing its own prospecting, the stack most likely to work is Apollo for finding and qualifying and Instantly for sending. Most coverage of this matchup raises that idea in passing and never costs it out.
There is no native integration between the two, but a maintained Zapier app pushes Apollo prospects into Instantly campaigns and creates Apollo contacts from new Instantly leads. Zapier is the bridge, and saying “you can use both” without naming it is useless.
The maths is the interesting part. One Apollo Basic seat for sourcing at annual billing is $49/month, and Instantly Hypergrowth for sending is $77.60/month annually, so the pair costs about $127/month. Over-buying either tool alone costs more: Apollo Organization’s three-seat floor starts at $357/month at annual billing, and Instantly Hypergrowth plus Hyper Credits runs from $294/month at month-to-month rates.
Buying your sourcing from Apollo also works out cheaper per contact than buying Instantly’s credits, since one Basic seat carries 30,000 credits a year against 18,000 for a year of Growth Credits. Size that seat carefully, because export credits are reported not to roll over and Apollo does not publish a per-tier export allowance. Running both starts paying at roughly two active clients, or as soon as you need more than about 1,500 fresh verified contacts a month.
Final Verdict: Instantly for Sending, Apollo for Finding
For an agency running cold email on behalf of clients, Instantly is the better core tool, and the reason is billing rather than any feature. Inboxes do not multiply the bill the way seats do, so a workspace sending from forty mailboxes costs what a workspace sending from four costs. The caveat is the one this article keeps returning to: that flat fee is flat per workspace, and separated clients mean separate subscriptions, so model four clients before you sign up rather than after.
Apollo is the right answer when the bottleneck is knowing who to contact rather than reaching them, or when sequences include calls and LinkedIn touches. Instantly cannot substitute for either job. Watch the 3-seat minimum on Organization, which is what catches small teams out: the tier that looks like $119 per seat is really a $357/month floor at annual billing.
Before you buy, open both pricing pages and check them against the billing period you actually intend to use. The gap between the monthly and the annual figure is the single largest source of confusion in this matchup, and it is why the prices in older articles look wrong rather than merely out of date. One operational instruction is worth repeating whichever way you go: export your reply history before you cancel anything.
Instantly vs Apollo FAQs
Is Instantly’s entry plan $37 or $47 a month?
Both, depending on billing. $47 is the month-to-month price for the Growth plan and $37.60 is the same plan billed annually. Older comparisons quote one or the other without saying which, which is why the figure looks inconsistent from article to article. Neither number includes the lead database or the CRM.
Does Apollo still have email warmup?
Yes, in two separate features. Apollo retired its original peer-to-peer warmup pool in 2024 and now runs Inbox Ramp-up for mailboxes with existing send history and Email Warmup for new ones, both gated to select plans. Comparisons that say Apollo has no warmup are describing 2024, not the current product.
Which is cheaper for an agency?
Instantly, until you need separated client workspaces. Its flat fee covers unlimited inboxes where Apollo charges per seat. But each white-labelled client needs its own paid workspace from the Hypergrowth tier up, so the advantage narrows with every client you add and can disappear entirely past four or five. Model the client count you expect in twelve months, not the one you have today.
Can Apollo be used by agencies managing multiple clients?
Yes. Apollo runs a Solutions Partner programme with four tiers and 20% lifetime commission, and its partner materials describe client sub-accounts. It is a reseller structure rather than a white-label multi-tenant product, so it suits agencies that resell Apollo more than agencies that want branded client portals.
What happens to my campaigns if I cancel Instantly?
They pause. Accounts, warmup and campaigns stop once the Email Outreach plan expires, at cycle end if it is your only subscription and immediately if you have several. For done-for-you accounts, Unibox conversation history is deleted after a 24-hour grace period, so export replies before you cancel.
Is Instantly’s 450 million contact database bigger than Apollo’s?
Bigger, but not the same kind of thing. Instantly’s figure covers the combined reach of seven third-party providers queried in sequence, while Apollo’s roughly 275 million is one index it owns and filters deeply. For finding a known address, Instantly’s chain is useful. For working out who to target, Apollo’s is more useful.
