FullEnrich vs Bookyourdata 2026

Short answer: pick FullEnrich if you already have a list (LinkedIn export, CRM, CSV) and want to fill in emails and mobiles through a waterfall of 20+ sources, paying only when the data is found, from $29/month. Pick Bookyourdata if you have no list at all and want to buy one, filtered on 100+ criteria from a database of 250M+ contacts, pay-as-you-go with no subscription and an accuracy guarantee. FullEnrich edges the overall (3.9 vs 3.8) on enrichment, cost-per-email and integrations; Bookyourdata wins support, a credit model that never expires and a money-back guarantee.

The mistake most comparisons make: framing them as two interchangeable tools. They do not answer the same question. Bookyourdata answers "I have no contacts, give me some." FullEnrich answers "I have contacts, find me their emails and mobiles." This page decides by use case, runs the real cost-per-contact math, and says when one makes the other pointless.

04Steady EU outbound, lists refreshed every month
FullEnrich

FullEnrich's waterfall caps the cost of a work email at 1 credit, covers Europe well, and automates through n8n, Make or Clay. On recurring email volume, the cost per contact stays well below a database at $0.30 to $0.40 a contact.

FullEnrich vs Bookyourdata at a glance

Every cell is grounded in both tools' pricing and product pages and our own testing. Read the "model" row first: one enriches a list you provide, the other sells you a filtered list. It is not the same buy, so some rows do not compare head to head.

Five rounds

Criterion by criterion, head to head

The five criteria we score on each review page. On a tight score, we still make a call.

Round 1 · Ease of use

01 Round 1: from an empty account to a usable list.

FullEnrich
4.0/5
WinnerBookyourdata
Bookyourdata
4.2/5
Our verdictEase of use · Winner : Bookyourdata

Bookyourdata takes this round 4.2 to 4.0, and it is tighter than the gap suggests. On the Bookyourdata side you start with nothing: you stack filters (job title, industry, size, country, technologies used), watch the matching contact count update live, buy, and download. The query builder is guided, and on a well-scoped search you hold a ready audience in a few minutes.

FullEnrich is not far behind: you paste a list or import a CSV, run the waterfall, export, and get clean emails in the first session with no setup. The honest snag is the native LinkedIn extension shut down in mid-2024, which pushes sourcing toward bulk and the API rather than a click on a profile. Both are easy to pick up. Bookyourdata wins by a hair because its guided path gets you to a usable list faster when you start from zero, where FullEnrich assumes you already arrive with your targets. The one catch on the Bookyourdata side: several G2 reviews find the UX a bit rigid once you stack a lot of filters.

FullEnrich

Choose FullEnrich if you already have your targets and just want to complete them, with nothing to configure.

Bookyourdata

Choose Bookyourdata if you start from zero and prefer a guided filter builder to assemble your audience.

Round 2 · Value for money

02 Round 2: what a usable contact really costs.

FullEnrich
3.8/5
Tie
Bookyourdata
3.8/5
Our verdictValue for money · Tie

This round is a tie, 3.8 across the board, because both models are good for opposite reasons. Bookyourdata bets on pay-as-you-go with no subscription: $99 for 250 contacts, $299 for 1,000, down to about $0.10 a contact on big batches, credits that never expire, and a guarantee that recredits any inaccurate contact. For a team that buys 300 contacts a quarter, paying nothing between campaigns and getting credits back on dead emails is a real argument.

FullEnrich answers on a different field, just as solid. Paying on results makes the work email unbeatable at 1 credit, around $0.055 on the Pro plan, ten times cheaper than the entry-level Bookyourdata contact. The trap is the mobile at 10 credits, which drains a pool of 1,000 credits fast in a month heavy on numbers. In the end neither pulls ahead: on recurring high-volume email, FullEnrich costs far less; on one-off purchases with no commitment, Bookyourdata's model protects the budget better, mainly thanks to the guarantee. The right pick depends on your cadence, not on a winner.

FullEnrich

Choose FullEnrich if you enrich a lot of emails on a recurring basis and want the lowest unit cost.

Bookyourdata

Choose Bookyourdata if your use is occasional and lifetime credits plus the guarantee matter more than the price per email.

Round 3 · Features and depth

03 Round 3: enrichment engine vs targeting engine.

FullEnrich
3.9/5
WinnerFullEnrich
Bookyourdata
3.6/5
Our verdictFeatures and depth · Winner : FullEnrich

FullEnrich wins this round 3.9 to 3.6, but the gap is mostly down to what each tool is. Its depth is the waterfall: 20+ sources queried in cascade, enrichment from a LinkedIn URL, reverse email lookup, bulk processing and a documented public API. Where a single-source tool often tops out between 40 and 60% find rate, the cascade pushes around 80%. That is technical depth, not catalog breadth.

Bookyourdata puts its depth elsewhere, and it is real: 100+ data points per contact, technographic filtering (the technologies the target company uses), multi-step email verification at export time. The flip side is single-source: if a prospect is not in the database, you get no result, where FullEnrich's waterfall goes looking elsewhere. And accuracy degrades with volume: very clean under 500 contacts, the bounce climbs noticeably past 10,000, a sign of data aging in the database. FullEnrich takes the round because its engine stays flexible whatever the input; Bookyourdata stays the best when your target is broad and well indexed.

FullEnrich

Choose FullEnrich if you want an engine that finds the data even when one source runs dry.

Bookyourdata

Choose Bookyourdata if fine filtering by technology and industry across a large database is what matters.

Round 4 · Customer support and assistance

04 Round 4: who picks up when things go wrong.

FullEnrich
4.0/5
WinnerBookyourdata
Bookyourdata
4.3/5
Our verdictCustomer support and assistance · Winner : Bookyourdata

Bookyourdata takes this round 4.3 to 4.0, and it is one of its most consistent strengths. Support is 24/7 chat with real agents, the company shows an A+ rated BBB profile and over ten years of history, and contact stays human even on small purchases. When an export goes wrong or a batch holds questionable contacts, the money-back guarantee acts as a safety net and the claims process is described as smooth.

FullEnrich is a notch behind here. The product is simple, so you rarely open a ticket for pure enrichment, which works in its favor day to day. But the external signal is not ideal: the Trustpilot score is low, fueled mostly by people who were found in the data, and the tool does not really respond to negative public reviews. Support channels and response times are not clearly detailed on the site. For a self-sufficient team running enrichments without a hitch, that is enough; but on the "someone answers and fixes it" dimension, Bookyourdata is ahead.

FullEnrich

Choose FullEnrich if a simple tool that rarely needs help is enough for you.

Bookyourdata

Choose Bookyourdata if 24/7 human chat and a guarantee that covers the misses reassure you.

05 Round 5: plug into the stack vs deliver a file.

FullEnrich
4.2/5
WinnerFullEnrich
Bookyourdata
3.1/5
Our verdictAvailable integrations · Winner : FullEnrich

FullEnrich takes this round 4.2 to 3.1 on connectivity. It syncs with HubSpot, Salesforce and Pipedrive, plugs into Zapier, Make, n8n and Clay, and exposes a documented REST API that returns results by webhook or polling. For a RevOps team that wants to enrich continuously from a workflow, that is the right surface: you trigger enrichment when a lead comes in and get the data into the CRM with no copy-paste.

Bookyourdata covers the essentials but stops sooner. CSV export is native, and you find connections to Salesforce, HubSpot, Mailchimp and Outreach, plus Zapier; the API exists but mainly on the Enterprise side. The default behavior stays list download, not real-time orchestration. No native n8n or Make connector is documented, where FullEnrich already lives inside those automation tools. If your stack revolves around Clay, n8n or a synced CRM, FullEnrich slots in better; if you just want a clean file to import, Bookyourdata gets the job done.

FullEnrich

Choose FullEnrich if you enrich from an automated workflow and want the API early, with no enterprise plan.

Bookyourdata

Choose Bookyourdata if a CSV export and a few CRM connectors cover all your needs.

FAQ · 10 questions

Frequently asked questions

  • What is the difference between FullEnrich and Bookyourdata?
    FullEnrich is a waterfall enrichment engine: you provide a list of names or domains, it cascades 20+ sources to find emails and mobiles, and you pay only for the data found. Bookyourdata is a B2B database of 250M+ contacts that you filter on 100+ criteria and then buy on demand. In other words, FullEnrich completes a list you already have, Bookyourdata sells you one you do not. If you have your targets, FullEnrich. If you start from zero, Bookyourdata.
  • FullEnrich or Bookyourdata, which is cheaper?
    It depends on usage. On email at volume, FullEnrich is clearly cheaper: about $0.055 per work email on the Pro plan at $55/month, against $0.40 to $0.10 per contact on Bookyourdata depending on the pack. But Bookyourdata has no subscription, its credits never expire and it refunds inaccurate contacts, which makes it more economical for occasional use. For recurring high-volume enrichment, FullEnrich wins on cost. To buy 250 contacts once a quarter, Bookyourdata protects the budget better.
  • Is Bookyourdata's accuracy guarantee reliable?
    Yes, but it holds best at low volume. Bookyourdata claims 97% accuracy with email verification at export and refunds in credits any inaccurate contact, and users confirm that refund happens without friction. On the other hand, the real bounce rate climbs with batch size: very clean under 500 contacts, it rises noticeably past 10,000, because the data in the database ages. The guarantee is real, but count it as a safety net, not as a promise of 97% held across 15,000 contacts at once.
  • Does FullEnrich find contacts or only emails?
    FullEnrich finds work emails, personal emails and mobile numbers, but it does not provide a database to browse. It needs a starting point: a name plus a company, a domain, or a LinkedIn URL. From there, the waterfall pulls the contact data across its 20+ sources. If your need is "I have no list, give me 1,000 marketing decision-makers in French SaaS," it is not the right tool: that is exactly what Bookyourdata does. FullEnrich shines when you already have the identities and only the contact details are missing.
  • Do both find mobile numbers?
    Yes, but differently. FullEnrich charges 10 credits for a mobile, against 1 for a work email, so a month heavy on numbers burns fast, even on results. The smart move is to reserve mobile enrichment for high-value accounts. On Bookyourdata, the phone is included in the contact credit when it is available, with no dedicated surcharge, but the fill rate of the mobile field varies by target and the sources do not quantify it clearly. On both, expect stronger mobile coverage in the US than in Europe.
  • Can you use FullEnrich and Bookyourdata together?
    Yes, and it is sometimes the smartest setup. Bookyourdata serves to buy a first filtered list when you have no targets, then FullEnrich re-enriches that list to fill missing mobiles or verify questionable emails through its waterfall. You pay for the database once, with no subscription, and you only spend FullEnrich credits on what is missing. It is useful when the database returns good targeting but incomplete mobile coverage, where FullEnrich's multi-source waterfall goes looking for the number elsewhere.
  • Are FullEnrich and Bookyourdata GDPR compliant?
    Both can be used in a compliant way, but the final responsibility sits with you as the data controller. FullEnrich declares itself GDPR and CCPA compliant and SOC 2 Type II certified, with a DPA and automatic deletion after a few months. Bookyourdata says it is GDPR-ready, with data from public records and sources licensed under legitimate interest. In either case, you need a lawful basis, clean handling of deletion requests, and care over EU-heavy prospecting. Document your processing before you scale.
  • Which one to choose for prospecting in Europe?
    FullEnrich has the edge on Europe in most cases. Its waterfall aggregates strong sources on EU and UK contacts and reaches a good multi-country find rate, where a single database often stays denser in the US. Bookyourdata covers 200+ countries but its accuracy is better on well-indexed US markets, and coverage thins out beyond North America and Western Europe. For EU-heavy prospecting on your own lists, FullEnrich. To buy a broad US database, Bookyourdata stays relevant.
  • Which is best for a solo operator or freelancer?
    Bookyourdata, in most starting cases. A solo operator often has no list yet and wants to buy one quickly, with no commitment: pay-as-you-go, lifetime credits and the guarantee fit that need. The exception is the freelancer already working on client lists or LinkedIn exports to enrich: there, FullEnrich and its $29/month entry paid on results work out cheaper. The right question is not price but starting point: no list, Bookyourdata; a list to complete, FullEnrich.
  • Which is best for an agency or RevOps team?
    FullEnrich, in general, because RevOps teams work from data they already own and want to enrich continuously. The HubSpot, Salesforce, Clay and n8n connectors and the API let you enrich on the fly inside the pipeline, and the cost per email stays low on recurring volume. Bookyourdata keeps its place when the agency has to build lists for clients who have none, industry by industry. Many teams end up keeping Bookyourdata for list acquisition and FullEnrich for continuous enrichment, rather than choosing.
