Apollo vs Clay
Apollo vs Clay for a founder building outbound: contact database plus sequencer vs enrichment workspace, credit models, data accuracy, MCP, who needs which.

You exported 500 "verified" contacts on Friday, sent the first 200 on Monday, and by Tuesday your Gmail is showing bounces. Someone on a founder Slack says "just use Clay." You open Clay, see a spreadsheet with 40 column types, and close it.
That is the usual entry point to an Apollo vs Clay decision, and it is the wrong framing. The two tools do different jobs. I run PumpGTM, which overlaps with both on the "who do I contact" question, so weigh the last section accordingly. Every fact about Apollo and Clay below comes from their own pricing and docs pages or from public reviews, meaning intact.
What each tool is
Apollo.io is a B2B contact database (240M+ contacts, 30M+ companies) plus an outbound engagement tool: email sequences, a dialer, and LinkedIn as manual task reminders. One seat gives you data and sending together.
Clay is a spreadsheet-style GTM data tool. It pulls leads from a CRM or its own database, enriches them by querying many data vendors in sequence (the "waterfall"), runs AI research through Claygent, and pushes results to a CRM or an email sequencer.
Short version: Apollo is a database with a sequencer bolted on. Clay is a workbench that buys data from other databases, Apollo included.
Pricing and credit models
Apollo's official pricing table is JavaScript-rendered and would not load as text when I fetched it, so plan prices come from two dated third-party breakdowns that agree with each other, and the credit rules come from Apollo's own FAQ. As of September 2026: Basic is $49 per user per month billed annually ($59 monthly), Professional $79 annual ($99 monthly), Organization $119 annual ($149 monthly) with a 3-seat minimum. Export credits per month are 10 on Free, 1,000 on Basic, 2,000 on Professional, 4,000 on Organization. An email costs 1 credit and a phone lookup 8. Even "unlimited" paid plans cap credits at the lesser of dollars paid divided by $0.025 or 1 million a year. Official FAQ at https://www.apollo.io/pricing.
Clay repriced in March 2026 into two meters: Actions (platform usage) and Data Credits (buying data and AI from vendors). As of September 2026: Free is $0 with 500 actions and 100 data credits a month, tables capped at 200 rows, no phone enrichment. Launch is $185 a month ($167 annual) with 15,000 actions and 2,500 data credits, adding phone enrichment and the Sequencer. Growth is $495 a month ($446 annual) with 40,000 actions and 6,000 data credits, adding CRM auto-sync and the HTTP API. Seats are unlimited on every plan. Actions never roll over; data credits on monthly plans accumulate up to 2x the monthly limit. Failed enrichments are refunded only "if a provider refunds us due to invalid data." Top-ups are reported at a 30% markup. Details at https://www.clay.com/pricing.

For a solo founder, Apollo is the cheaper door: $59 a month gets data and sequences. Clay's $185 gets you enrichment and an email sequencer but no database of its own to speak of and no LinkedIn.
Data accuracy complaints
Apollo's G2 is 4.7 from 9,696 reviews, but 503 of those reviews flag "Inaccurate Data." Capterra reviewers note "Some contact information is outdated and credit can runs out quickly with heavy usage," and that phone data is less accurate than email. On r/coldemail, users report exports of "verified" contacts producing 18% hard bounces on day one, and 32 to 38% bounces in a 500 to 1,000 lead test. The consensus there is to re-verify with another tool before sending. Trustpilot sits at 3.1 from 1,308 reviews.
Clay's accuracy story is different because Clay does not own most of the data. The waterfall hits providers in order until one matches, which is why one OpenAI team reportedly raised enrichment coverage from the low 40% range to over 80%. Mobile match rates are cited around 30 to 35%. The complaints are about cost, not bounces: "eating credits for no reason," "stealing credit usage by running stuff that was never intended to run," and an auto-update table setting that silently consumes credits. 42% of negative reviews mention credit burn, and one user spent $800 in a week while learning.
Put together: Apollo's risk is bad rows. Clay's risk is a bill you did not expect.
Learning curve and support
Apollo is a conventional SaaS app. Reviewers praise strong filters and call it cheaper than ZoomInfo for comparable coverage. Clay is a spreadsheet you program. A reviewer wrote it is "so complex... I still haven't gotten any benefit from the tool," while another said Claygent is "the feature that justifies the platform." A $350 a month Clay customer was told to "ask your LLM for help debugging." Clay is for a team with someone who will build and babysit workflows. If that person is also the one selling, budget the hours.
How both pair with a sender
Neither tool sends LinkedIn messages. Apollo's LinkedIn steps are reminders you complete by hand. Clay does not touch LinkedIn at all. Both send email: Apollo natively, Clay through its own Sequencer or by pushing rows to Smartlead, Instantly, Salesloft, Outreach or HubSpot.
So the typical stack is Apollo or Clay for the list, plus a separate LinkedIn sender. If you want that sender to have an MCP server too, our LinkedIn outreach tools with an MCP server list is the place to start.
MCP servers
Both are ahead of most of the category here. Apollo runs an official remote server at mcp.apollo.io/mcp with OAuth or API key and 40+ tools, plus native connectors in Claude, ChatGPT and Perplexity. It costs nothing extra on any plan, though free accounts on a personal email cannot use search or enrich. Clay's official server works with ChatGPT, Claude and Codex, lets admins set per-rep credit limits, and gives 500 free credits on first connect. Plan gating is not published.
Getting data out
Apollo exports contacts from Search > People as CSV, all emails or verified only, and each exported record consumes an export credit (10 a month on Free). The free plan caps bulk actions at 25 records. Our guide to exporting contacts from Apollo has the click path. Clay exports the current table view as CSV from the Actions menu, with finished files under "Available Exports." Duplicate a view and hide columns first, because the export mirrors what you see. No credit charge on CSV export is published.
Who needs which
Get Apollo if you are a small US-focused sales team that wants a large database and email sequences in one seat, you will re-verify emails before sending, and your outreach is email plus phone.
Get Clay if you have a RevOps or growth person who will build the waterfall, you already own a sequencer or CRM, and your problem is enrichment coverage across many vendors rather than finding a list in the first place.
Get both if you are running a real SDR team: Clay to build and enrich, Apollo as one of the data sources inside it and possibly as the sender. The AI SDR tools for startups shortlist shows where each fits. If Apollo is the piece you are replacing, our Apollo alternatives page covers the field.
Where PumpGTM fits
PumpGTM starts from a different premise: the best list is not a slice of a 240M-row database, it is the set of companies doing something right now that says they need you. It watches live signals (a Greenhouse, Lever or LinkedIn Jobs posting, a funding round, a tooling change, engagement on a relevant LinkedIn post), scores every lead, and sends nothing to anyone under 60 out of 100. It also imports Sales Navigator lists.
Then it does the part Apollo and Clay hand off: it runs a paced LinkedIn sequence from your own account (day 0 profile view, day 1 like a relevant post, day 2 a personalized connection request, then a contextual follow-up), with optional email steps from your own Gmail, Microsoft 365 or IMAP mailbox, sorts the replies, and hands you the qualified ones. It runs as an MCP server for Claude, Cursor and Codex as well.
It is $75 a month (list $99) for up to 3,000 leads a month as of September 2026, with a 7 day trial. It is not a data vendor, it has no phone channel, and it launched in September 2026. Last week for one SF team: 546 invites, 356 accepted (68%), 98 qualified replies, 38 enterprise demo meetings. See how PumpGTM finds buyers or start the 7 day trial.
Questions people ask
Is Clay a replacement for Apollo? Not directly. Apollo owns a 240M+ contact database and sends email sequences. Clay enriches lists by querying many vendors (Apollo can be one of them) and sends email through its Sequencer or a partner tool. Many teams use Apollo as a source inside Clay.
Which is cheaper for one founder? Apollo. Basic is $49 per user per month billed annually or $59 monthly as of September 2026. Clay's first paid plan, Launch, is $185 a month, though seats are unlimited.
How accurate is Apollo's data? Mixed. G2 shows 503 reviews flagging inaccurate data, and r/coldemail users report 18% to 38% bounce rates on "verified" exports. The common advice is to re-verify with another tool before sending.
Why do people complain about Clay credits? Actions never roll over, failed enrichments are refunded only when the provider refunds Clay, auto-update settings can consume credits silently, and top-ups carry a reported 30% markup. One user spent $800 in a week while learning.
Do Apollo and Clay have MCP servers? Yes, both. Apollo's is at mcp.apollo.io/mcp with 40+ tools on any plan. Clay's official server supports ChatGPT, Claude and Codex with per-rep credit limits.
Does either one send LinkedIn messages? No. Apollo creates LinkedIn task reminders you complete manually. Clay does not send on LinkedIn. You need a separate sender for that channel.
