Contact enrichment.

Contact enrichment fills gaps in records you already own — job title, work email, direct dial, firmographics, LinkedIn URL — by matching each record against an external identity graph. It is not list-buying: you start with contacts you have. Every tool in the category stops at the finished record and hands you a CSV.

I co-founded ContactLevel, which does one specific kind of enrichment. So read this knowing where I sit. I have tried to make the parts about other vendors checkable — every price and figure below was pulled from the vendor's own live page on 29 July 2026, and I have said so where a page would not give up a number.

The reason this page exists is a pattern I see on nearly every sales call. Someone says "we already have HubSpot enrichment turned on," and then, two questions later, it turns out their contact records still have no phone numbers. Both things are true. The gap between them is the whole category.

What is contact enrichment?

Contact enrichment is the process of filling missing fields on contact records you already own, by matching each record against an external identity graph or data provider. You supply an identifier you already have — usually an email address, a LinkedIn URL or a name plus company domain — and get back the fields you were missing.

Three things distinguish it from the adjacent purchases people confuse it with:

→ It is not buying a database. A B2B data provider sells you access to build new lists. Enrichment operates on the list you already have. If you have no contacts at all, enrichment is not your problem yet.

→ It is not verification. Verification tells you whether the email you have still bounces. Enrichment tells you what you were missing in the first place. Most decent tools do both, but they are separate operations and they fail differently.

→ It is not intent data. Enrichment tells you who someone is. Intent data tells you what they are researching. Vendors bundle them; the buying decisions are unrelated.

What does enrichment actually add to a record?

Here is the honest shape of the problem. A CRM export — the thing you actually have — is much thinner than people remember.

The first four rows are what the whole category competes on. The last row is the one that decides whether your paid programme works, and it is the row most buyers do not know to ask about. More on that below.

Which contact enrichment tools should you compare in 2026?

The category splits into four pricing models that are not directly comparable, which is why "best contact enrichment tool" listicles are usually useless. A credit is not a seat is not a net-new contact.

Everything in this table was checked against the vendor's live page on 2026-07-29. Where a vendor does not publish a figure, the cell says so rather than guessing.

Sources: clay.com/pricing, fullenrich.com/pricing, hubspot.com/products/crm/data-enrichment, cognism.com/pricing, and ContactLevel's pricing page. ZoomInfo and Apollo are absent from the price column because neither page would give up a plan table on 29 July 2026, and I am not going to publish a number I could not read that day — see the ZoomInfo and Clearbit comparisons for the differences that are not about price.

The pattern in that table is the useful part, and it is not the one you might expect. Clay and FullEnrich will both sell you a personal email — FullEnrich prices it at 3 credits, Clay runs a dedicated personal-email waterfall. So "nobody else returns the identifier" is not true, and I am not going to claim it.

The real split is the last column, and it is subtler than "who can push an audience." HubSpot can: it syncs contact lists straight into Facebook, Google and LinkedIn as ads audiences, and has for years. But it syncs them with the work email it already had, which is the identifier the platform cannot match — so you get the convenience of the sync and the 30% match rate anyway. Clay, FullEnrich and Cognism go the other way: they will find you a personal email, then hand it back as a row in a table and leave the exporting, uploading and per-platform identifier guesswork to you.

That is not an oversight in either direction — none of them sell to a marketing buyer who needs a custom audience to activate. The two halves of the job just sit in different products. If you are buying enrichment to fix outbound, most of this table works, and a waterfall will be cheaper than us. If you are buying it to fix paid, the record is the easy half.

What is waterfall enrichment, and do you need it?

Waterfall enrichment queries data vendors in sequence rather than relying on one. Provider one returns nothing for a mobile number, so the request falls through to provider two, then three, until a field comes back filled or you run out of providers. You pay per successful find rather than per seat.

The logic is sound: no single vendor has complete coverage, and coverage varies sharply by geography, seniority and company size. Querying five in sequence beats querying the best one.

Three things to know before you buy into it:

It is the most contested search term in this whole category. If you search waterfall enrichment today you get Apollo, Cognism, ZoomInfo, FullEnrich, BetterContact, LeadDelta and Autobound — every one of them a vendor with a dog in the fight, and several of them upstream sources for the others. Read any of those pages knowing the author sells the answer.

The pricing unit changes your behaviour. FullEnrich charges 10 credits for a mobile and 1 for a work email at $0.055/credit, which means a mobile costs about $0.55 and a work email about $0.055. That is cheap per lookup and expensive per 100,000-record CRM refresh. Clay includes waterfalls on every plan but meters data credits, so the cost lands in how many enrichment steps your table runs, not how many contacts you have.

You are now operating a pipeline. A waterfall has ordering, fallbacks, per-provider costs and failure modes. That is a real ops job. Teams who buy Clay and never staff someone to run it end up with an expensive spreadsheet.

Where ContactLevel sits, plainly: it is not a waterfall. It runs one identity graph, not a sequence of vendors, and it has no per-field credit menu. If your goal is the cheapest possible mobile number at volume, a credit-based waterfall will beat it — and it will also return you a personal email, so do not let anyone tell you otherwise. What a waterfall will not do is take the finished list, resolve the remaining identifiers, and push a matched audience into your LinkedIn, Meta, Google, Reddit and X ad accounts. That last step is the part we are for.

Why does enrichment change your ad match rate?

This is the part I end up explaining on almost every call, so here it is in one paragraph.

Your CRM stores work emails. Nobody signs up to Meta with their work email. They use the personal one. So when you export 10,000 CRM contacts and upload them as a custom audience, the platform is trying to match jane@acme.com against an account Jane created with a personal address, and roughly 30% of the list matches. The other 70% of the people you paid to identify never see the ad.

Enrichment that only fills CRM fields does not move this number at all. Adding a revenue band and a seniority level to Jane's record does not help Meta find Jane.

Enrichment that resolves each business identity to the personal identifiers the platforms actually key on does move it. That is the mechanic behind contact-level targeting, and it is what takes a list from roughly 30% to 70-99% matched across LinkedIn, Meta, Google, Reddit and X. The full arithmetic — including why "match rate" means three different things depending on who is saying it — is in B2B match rates.

How do you enrich contacts in HubSpot?

HubSpot ships native enrichment, and it is genuinely included: the product page states enrichment is included in paid Smart CRM plans "no additional cost, no extra tools, and no integrations needed," backed by an index of over 100 million company domains and 380 million email addresses (checked 2026-07-29).

The important detail is scope. HubSpot publishes the exact list of contact properties it will enrich, and as of 29 July 2026 it is 14 properties:

City, Country, Country Code, Employment Role, Employment Seniority, Employment Sub Role, Enrichment opt-out, Enrichment opt-out timestamp, First Name, Job Title, Last Name, LinkedIn URL, State/Region, State/Region Code.

Read that list again. There is no email address on it. There is no phone number on it. Two of the fourteen are opt-out bookkeeping fields.

Company records get a much wider set — 27 properties including annual revenue, employee count, industry, description, web technologies, LinkedIn handle and year founded. Note that a phone number does appear on the company list. It is the company switchboard, not the person's line. So HubSpot enrichment is strong on firmographics and role classification, and does not solve reachability. Both lists checked at knowledge.hubspot.com/records/enrich-your-contact-and-company-data on 2026-07-29.

That table is the entire reason hubspot contact enrichment is a search term with a third-party market behind it. If someone tells you HubSpot enrichment is already handling their data, ask them what percentage of their contact records have a populated phone number.

ContactLevel connects to HubSpot as a CRM source, enriches the contacts you add to an audience, and writes the enriched data back. Details on the data enrichment product page.

How do you enrich contacts in Salesforce, Pipedrive and other CRMs?

The mechanics are the same across CRMs, and there are only three integration patterns worth distinguishing:

1. Native, bundled. The CRM vendor sells its own enrichment (HubSpot Breeze, Salesforce Data Cloud). Cheapest, narrowest scope, no extra contract.

2. Sync-and-write-back. A third-party tool connects to the CRM, pulls records, enriches them, and writes the filled fields back on a schedule. This is how ContactLevel, Cognism CRM Enrichment and most dedicated tools work. The thing to check before you sign: which direction the sync runs, and whether it overwrites. A tool that overwrites a rep's manually corrected phone number with a stale third-party one is worse than no enrichment.

3. API-at-point-of-use. You call an enrichment endpoint at form submit, at lead creation, or inside a workflow. Best data freshness, most engineering work.

Whichever pattern you pick, run the same test first: export 500 records of your actual ICP, send them through a trial, and count fill rate by field. Not the vendor's sample. Yours. Fill rates on a European mid-market list and a US enterprise list are not remotely the same number, and no vendor's marketing page will tell you that.

---

What should a contact enrichment API return?

If you are integrating rather than clicking, this is the spec to hold vendors to. B2B contact data decays continuously — people change jobs — so a field with no provenance and no date on it is a field you cannot act on.

Ask for a sample response body against your own ICP before you sign. Every vendor will show you a payload for a VP of Sales at a 5,000-person US SaaS company, because that record is complete in every database on earth. Ask for the same call against a 40-person German manufacturer.

ContactLevel exposes contact, company, audience and website-visit endpoints; enrichment runs as contacts enter an audience rather than as a separate per-field call.

What contact enrichment does not do

The boundary matters more than the feature list, so here it is without softening.

Enrichment does not create demand. A complete record of someone who has never heard of you is a complete record of a cold prospect. It makes outreach possible, not effective.

No tool fills every field. Fill rate varies by geography, seniority and company size, and every vendor's headline number is measured on their best-case list. ContactLevel's own coverage is strongest in the US and degrades outside it — we have seen an EMEA audience match as low as 25%. That and the rest of our measured limits are documented in what we track.

ContactLevel is not a waterfall and does not sell per-field credits. No menu of "10 credits per mobile." If you want to price-shop individual lookups, this is the wrong tool.

ContactLevel does not enrich anonymous website traffic. We identify a visitor when that person is already in one of your audiences. If you need cold IP-to-person resolution on net-new traffic, run RB2B, Dealfront or Datamoon upstream and activate their output through us. Several customers do exactly that.

Enrichment does not fix a dirty CRM on its own. If 30% of your records have no company domain, enrichment has nothing to key on for those records and will return nothing. Deduplicate and normalise first.

Compliance is not transferable. A vendor being GDPR-compliant does not make your use of the data lawful. Your legal basis for processing is yours.

What should you actually buy?

Three honest paths, depending on the job:

You need phone numbers and emails for outbound, cheaply. Buy a credit-based waterfall. FullEnrich at $55/month for 1,000 credits is the cheapest per-find mobile lookup I could verify on 2026-07-29 — a mobile lands at about $0.55. Clay is cheaper to get into on annual billing ($54/month) and worth it if you also need orchestration, but only if you are willing to staff it.

You need firmographics and role data inside HubSpot and nothing more. You already own it. Turn on native enrichment and stop shopping.

You need the list to be advertisable, not just complete. A waterfall gets you the record; it stops there and hands you a CSV. That last step — resolving the identifiers each platform keys on and pushing the audience into the ad accounts — is what ContactLevel's enrichment is built for — 50-70 data points per contact including the ad-platform identifiers, 70-99% match rates on LinkedIn, Meta, Google, Reddit and X, priced per net-new contact rather than per credit. Published pricing is on the pricing page: $1,000/month for 10,000 contacts, $3,000/quarter for 50,000, with a 14-day trial and 10,000 free contacts.

Run a match test on your own list before you commit budget to any of the three. Including ours.
