FoxKnock vs Apollo: researched leads or a big database

FoxKnock vs Apollo in one line: Apollo is a large contact database with sequences and a dialer, billed per seat, while FoxKnock researches a short list of accounts, cites its sources and, by default, waits for your approval before it sends from your own mailboxes.

We make FoxKnock, so weigh this page accordingly. Every Apollo fact comes from Apollo's own pages or a labeled third-party source, checked on 2026-10-17, and we say where Apollo is the better pick.

Facts checked from public sources listed at the end. Tools change often, so check before you decide. Written by the FoxKnock team, so read it knowing who wrote it.

The short answer

Choose Apollo if you need a large contact database, phone numbers, a built-in dialer or enterprise security paperwork: it is the broader product, and its price per verified email is much lower than ours. Choose FoxKnock if you sell to a short list of accounts, want each lead researched with sources you can click, and want drafts to wait for your approval by default. If you are looking for an Apollo alternative because of per-seat pricing or credits that expire, FoxKnock changes both, but it does not replace Apollo's database. Some small teams could reasonably use both.

Choose FoxKnock if

  • You sell to a short list of accounts and want a cited research dossier on each one, not just a name and an email.
  • You want drafts to wait for approval, with automatic sending only after a sequence has earned it.
  • You prefer plan prices that include seats and one credit balance that rolls over, over per-seat plans with credits that expire.
  • You send into Europe and want country rule packs, lawful-basis checks and an Article 14 notice link built in.
  • You want to start from your best customers and find companies that resemble them.

Choose Apollo.io if

  • You need a large built-in database of contacts and accounts, with phone numbers, to build lists in bulk.
  • Your team makes calls. Apollo has a built-in dialer, and FoxKnock has no dialer.
  • You rely on many integrations or want an MCP connector for Claude, ChatGPT or Perplexity today.
  • A security review requires SOC 2 and ISO 27001 listings or SSO. FoxKnock is not yet certified and has no SSO.

  • Starter$49/mo, 5,000 credits
  • Growth$149/mo, 20,000 credits
  • Agency$399/mo, 60,000 credits
  • EnterpriseCustom

One meter for everything: credits at $0.01 that never expire. Failed lookups are free, bounced verified emails are refunded, and you can set a monthly cap.

At default prices (they can change; see pricing) a found and verified email costs 11 credits, or $0.11 at list price. Apollo charges 1 credit for a verified email, about $0.02 on Basic billed annually (our arithmetic: $588 a year divided by 30,000 credits, which counts the whole seat price against credits).

Full pricing and cost calculator

Apollo.io

Checked 2026-10-17 on Apollo's pricing page. Its plan cards load with JavaScript, so some text-only tools show no prices. Apollo bills per seat, every seat on an account shares one plan, and credits are pooled across the team.

PlanAnnual billing, per seat per monthMonthly billing, per seat per monthCredits per seat
Free$0$0900 a year, granted monthly
Basic$49$6530,000 a year
Professional$79$9948,000 a year
Organization$119 (3-seat minimum)Annual billing only72,000 a year

On monthly billing the same allowance is granted monthly: 2,500 credits per seat on Basic and 4,000 on Professional. Apollo calls this introductory pricing and says features and prices may change.

Per the pricing page, an email costs 1 credit, a phone number 8, enrichment 1 to 8, AI research 1 per run and US dialer calls 1 per 30 seconds. Apollo's help center counts one AI research run for each record and each column. Domains and mailboxes bought through Apollo also draw credits: 1,500 per domain a year, and 300 (Apollo SMTP), 800 (Google Workspace) or 1,500 (Microsoft 365) per mailbox a month, per its knowledge base.

Credits are granted up front for each billing cycle and do not roll over, and that includes add-on credits, which renew until you remove them. Annual billing is a 12-month commitment, cancellations take effect at the end of the current term, and downgrades do not refund unused time.

Plan names differ on the page itself. The cards show Free, Basic, Professional and Organization, while the FAQ lists Free, Basic, Professional and Custom (custom volumes, SSO, advanced security). We could not confirm how Custom and Organization relate, so check which tiers you are shown. For credit units in more depth, see our Apollo credits explainer.

Apollo vs FoxKnock: where Apollo is stronger

Apollo is the broader product, and for several jobs it is the better pick.

  • Data. Apollo's homepage claims 240M+ contacts and 30M+ accounts. FoxKnock owns no database, so we do not quote a size.
  • Calling. Apollo's pricing table lists a US dialer from the Basic plan, with credits applying (1 credit per 30 seconds), and it sells phone numbers at 8 credits each. Its September 2026 plan article describes the dialer as a Professional feature, so check which your plan shows. FoxKnock has a phone finder (one provider, charged only when a number is found) and call steps that are tasks with a script, but no dialer.
  • Breadth. Apollo's homepage lists 200+ integrations (its pricing page names Salesforce, HubSpot and Salesloft among them) and AI agents that research accounts, build lists, write outreach and book meetings. We have not tested those agents. FoxKnock offers HubSpot (one-way sync), Slack alerts, a REST API and webhooks.
  • AI assistants. Apollo's MCP connector works with Claude, ChatGPT and Perplexity on any plan, Free included. FoxKnock's native MCP server is coming soon. Today you can give an assistant a read-only API key (API keys are a Growth plan feature).
  • Security reviews. Apollo's homepage names SOC 2 and ISO 27001 in its Apollo for Enterprise section. Its pricing table lists SSO on the Organization plan, and its FAQ points to Custom plans for SSO. FoxKnock is not yet certified and has no SSO.
  • Track record. Apollo's pricing page shows 4.7 out of 5 from 9,690 reviews, without saying which site they are from. Trustpilot, a third-party site, shows 3.1 out of 5 from about 1,370 reviews, so read recent reviews on more than one site. FoxKnock launched in October 2026 and has no track record yet.

FoxKnock as an Apollo alternative: where it differs

FoxKnock can start from your best customers. You give it your website and a few customers, and it finds companies that resemble them. You decide which ones to research before anything is written. Apollo's pricing table also lists people and company lookalikes, marked beta, so the difference is less a missing feature than where the work starts and what happens next.

  • Cited research. Research produces evidence cards: one claim, the source URL, a verbatim quote and the date it was read. Cards expire (90 days for news, hiring and funding, a year for the rest), so a stale fact does not end up in a new email.
  • Drafts wait for you. Every sequence has an approval level, and review each is the default. Auto-sending unlocks per sequence, and only after 50 emails approved one by one, with under 10% edited and under 5% rejected. Nothing is approved by a timer. The one message that can go without per-message approval is the opt-in booking-link reply to a meeting request.
  • A quality gate for claims. It blocks drafts whose specific claims have no source. The claim check is done by AI, so it can miss things, and steps you write yourself skip it.
  • One meter. Plan prices include seats, and everything draws from one credit balance that rolls over. Email finds, phone finds, enrichment and research charge only on success.
  • Built-in EU tools. Editable country rule packs, a lawful basis per contact, an Article 14 notice link in first emails, suppression lists, retention, and access export and erasure. See the GDPR tools. They help you stay within the rules; compliance remains the sender's job.
  • AI and hosting. FoxKnock's AI features run on Claude, by Anthropic, so the text they work on is sent to Anthropic. The app is hosted in Nuremberg, Germany.

Apollo.io pricing vs FoxKnock: what a month costs

This is a hypothetical, not a result from anyone's account. A 3-person agency wants 50 researched accounts a month: one decision-maker each, a verified email and an AI-personalized first email. It prices what each tool charges for these steps, not the quality of the research.

FoxKnock, at default prices (they can change; see pricing). Per account: discovery result 15 credits, standard research 225, contact found 5, email found 10, verification 1 and the AI-personalized email 20. That is 276 credits, so 50 accounts use 13,800 credits ($138 at list price). The Growth plan ($149 a month, 20,000 credits, up to 5 seats) covers it and leaves about 6,200 credits that roll over. Follow-ups from your own templates are free; AI-written ones cost 20 credits each.

Apollo, same team. Apollo bills per seat, so three seats on Basic cost $147 a month billed annually, or $195 billed monthly. The plan includes 90,000 credits a year pooled for the team (30,000 per seat). Fifty verified emails cost 50 credits. Apollo's AI research costs 1 credit per record per column, so a five-column pass over 50 accounts would add about 250.

FoxKnock GrowthApollo Basic, 3 seats
Monthly price$149$147 billed annually, $195 billed monthly
Credits in the plan20,000 a month, rolling over90,000 a year on annual billing, expiring at cycle end
Credits this example uses13,800About 50, or about 300 with a five-column AI research pass

The Apollo count leaves out phone numbers and AI-written emails. Apollo's pricing table gives Basic 250,000 AI-writing words a month, but we did not verify whether AI-written emails also use credits.

In dollars the two land close together here. The difference is what the money buys: FoxKnock's credits pay for cited research and drafts that wait for approval, while Apollo's seats include a far larger database (by its own claim) with room for much higher volume.

If your plan is volume, Apollo is cheaper by a wide margin. Finding and verifying 2,000 contacts a month in FoxKnock (contact, email and verification, 16 credits each at default prices) would use 32,000 credits, against about 2,000 on Apollo. Seat count changes the math too: five people on Apollo Basic cost $245 a month, while Growth stays at $149 for up to 5 seats.

Apollo calls its pricing introductory, so confirm the figures on its pricing page before you buy.

Switching from Apollo to FoxKnock

Moving is mostly a CSV job. Do not cancel Apollo until the new setup is sending.

  1. Export your contacts. In Apollo, filter to saved contacts or a list and export. Per Apollo's knowledge base, exporting saved contacts uses no credits. Include country, email status and the email-bounced column. Apollo says emails and phone numbers are not always included in an export by default and that exports of existing records are not enriched automatically, so check the export settings. Selecting net-new people from search saves them first, and each one with a verified email uses 1 credit.
  2. Import into FoxKnock. CSV import takes up to 5,000 rows per file and maps columns automatically: email, names, title, LinkedIn URL, phone, country, city, tags, company and domain. Split bigger exports. FoxKnock does not charge find credits for addresses you import, and it re-verifies an address before sending when the last check is older than 14 days (1 credit at default prices).
  3. Keep the country column. FoxKnock's default rules ask for a confirmed lawful basis before enrolling contacts in Germany, Austria, Italy, Poland, Denmark, Hungary, Canada and Australia, and they block contacts whose country is unknown until you set one. The rules are editable and are not legal advice.
  4. Bring your suppressions. Import anyone who unsubscribed, bounced or asked not to be contacted before you enroll a single contact.
  5. Rebuild sequences. FoxKnock cannot import Apollo sequences. Rebuild them, or let FoxKnock draft one from your playbook and edit it.
  6. Check mailboxes and domains. FoxKnock connects Google Workspace or any SMTP/IMAP server with an app password. Microsoft 365 is limited, because Microsoft no longer accepts passwords for IMAP, so test a spare mailbox first. If you bought domains or mailboxes in Apollo with credits, Apollo says access may be deactivated when credits run out or your plan changes, so confirm what happens to them before you cancel.
  7. Mind the notice period. Apollo says cancellations take effect at the end of the current plan term, and annual billing is a 12-month commitment.

Can you use Apollo and FoxKnock together?

Yes, and for some teams it is a sensible split: Apollo for bulk data, phone numbers and calling, FoxKnock for the accounts worth researching and writing to.

The bridge is CSV, because there is no live sync. FoxKnock does not use Apollo's API, and Apollo's API terms forbid using it to replicate or compete with Apollo's products, as Apollo determines in its sole discretion. Apollo's pricing page says its standard plans are for internal business use, so read Apollo's terms before you move exported data into another tool. This is not legal advice.

Suppression lists are per tool, so import each tool's unsubscribes into the other to avoid emailing someone twice. For a wider shortlist, see Apollo alternatives.

Try FoxKnock on your own short list

If each account matters, run a handful of your best customers through FoxKnock and compare the result with what Apollo gives you. The free plan includes 500 one-time credits and needs no card. At default prices (they can change; see pricing) that covers about two standard research reports.

Create a free account, run the same search in both tools, and keep the one that fits how you sell.

Frequently asked questions

Is FoxKnock cheaper than Apollo?

Not per contact. At default prices (they can change, see pricing) a found and verified email costs 11 credits, or $0.11 at list price. Apollo charges 1 credit, about $0.02 on Basic billed annually. For bulk lists Apollo is cheaper. FoxKnock's credits also pay for research and drafts, and its plan prices include seats, so monthly totals can land close for a small team doing deep outreach.

How much does Apollo.io cost per user?

Apollo charges per seat: Free is $0, Basic is $49 a month billed annually or $65 billed monthly, Professional is $79 or $99, and Organization is $119 billed annually with a 3-seat minimum. Each plan includes a yearly credit allowance per seat: 30,000, 48,000 and 72,000 on the paid tiers. These figures come from Apollo's pricing page on 2026-10-17, which calls them introductory, so confirm before you buy.

Do Apollo credits expire?

Yes. Per Apollo's pricing page, unused credits expire at the end of each billing cycle, add-on credits included. FoxKnock credits roll over: each monthly grant is added to your balance, and you can set a monthly spend cap in Billing. Failed lookups are free on FoxKnock. Apollo refunds a verified email that bounces within 30 days if you sent it from Apollo.

Does FoxKnock have a contact database like Apollo?

No. FoxKnock owns no database. It finds companies through web search and company-data providers, lets you research each one, finds people and work emails through a provider waterfall, and charges for results you accept or that are found. Coverage depends on what those sources return, so for sheer breadth of contacts Apollo's claimed 240M+ contacts go further.

Does FoxKnock have a dialer or phone numbers like Apollo?

Partly. FoxKnock has a phone finder that works through one provider and charges only when a number is found. It has no dialer: call steps in a sequence are tasks with a script, and you place the call yourself. Apollo lists a US dialer from its Basic plan, with credits applying, so if calling is central to how you sell, Apollo is the better fit.

Can I use Apollo and FoxKnock together?

Yes. Export contacts from Apollo to CSV (exporting saved contacts uses no credits) and import them into FoxKnock, which accepts up to 5,000 rows per file. There is no live sync. Keep your suppression lists in step across both tools so nobody is emailed twice after unsubscribing.

Is Apollo GDPR compliant for cold email in Europe?

Apollo says so: its pricing page carries a "GDPR Compliant" label and its homepage says it provides the tools to comply with GDPR, CAN-SPAM and DNC rules. We have not tested or audited that. Whether your outreach is lawful depends on your own lawful basis, notices and local rules. FoxKnock has built-in GDPR tools (country rule packs, lawful-basis checks, an Article 14 notice link, suppression, retention, erasure), but compliance stays with the sender. This is not legal advice.

Is FoxKnock a good Apollo alternative?

For some teams. FoxKnock fits teams that sell to a short list of accounts and want cited research and approval before anything sends. It does not replace Apollo's contact database, dialer or integrations. For a wider shortlist, see Apollo alternatives.
