Dropcontact and FullEnrich both find professional emails for your B2B prospects, but they take opposite approaches. Dropcontact computes and verifies each address in real time with its own algorithms, without relying on a database of named contacts. FullEnrich queries more than 25 data providers in a waterfall and only charges for contacts it finds and verifies, including mobile numbers.
Don't confuse FullEnrich with FullContact, a US identity resolution tool founded in 2010. FullEnrich even publishes its own comparison of FullContact and Dropcontact. This comparison covers Dropcontact and FullEnrich: features, pricing taken from both websites on September 15, 2026, data quality, and use cases.
Comparing the core features of Dropcontact and FullEnrich
Dropcontact generates addresses algorithmically and verifies them in real time on its own servers. On its Email Verifier page, Dropcontact claims 99% valid addresses for named emails and 97% on catch-all domains. Dropcontact stores no database of named contacts and markets itself as the only enrichment solution that is "100% GDPR compliant", a claim best read as the vendor's own.
Its features cover finding and verifying professional emails, enriching records (salutation, LinkedIn profile, website, industry, NAF code, SIREN, EU VAT number), detecting and merging duplicates without losing information, fixing swapped first and last names and capitalization, and detecting company changes when you import a file.
FullEnrich bets on coverage: the tool queries more than 25 sources in sequence, including Clearbit, Hunter, Wiza, ContactOut, and Snov, and stops at the first verified result. Its strength is mobile numbers, which cost 10 credits versus 1 credit for a professional email. Any landlines it finds are free. FullEnrich claims an email find rate above 80%. For mobiles, its own sample calculation assumes 50 to 70%, depending on the contact's region and seniority.
On integrations, Dropcontact sells a separate CRM subscription for Pipedrive, HubSpot, and Salesforce, distinct from the Email Finder: credits from one can't be used in the other. Dropcontact also offers an API, an MCP server, and a Google Sheets add-on. FullEnrich includes the HubSpot integration, the API, an MCP server, no-code connectors, and bulk CSV import on every plan, with unlimited users.
The two tools complement each other more than they compete: Dropcontact for cleaning and maintaining an existing database, FullEnrich for finding mobile numbers and covering regions where a single provider lacks data.

At Dropcontact, the Growth plan adds credit rollover, LinkedIn enrichment, and company data on top of Starter. At FullEnrich, the price per credit drops with volume, from $0.058 at 500 credits to $0.035 at 100,000 credits per month. Both vendors offer custom quotes for high volumes: Dropcontact from 200,000 credits per month, FullEnrich for agencies and API resellers.
To size your needs, FullEnrich gives its own example: 1,000 contacts with email and mobile use between 5,800 and 7,800 credits, which puts you on the 10,000-credit tier at $499 per month. For emails only, 1,000 credits at $55 covers roughly the same number of contacts.
Performance and data quality
Dropcontact doesn't query any existing database: every request triggers a computation and a check on its test servers. The figures of 99% valid named emails and 97% on catch-all domains are published by Dropcontact and have not been independently measured.
FullEnrich buys data from its providers on each request, then runs it through three independent verification engines. A single disagreement is enough to reject an address. FullEnrich reports that 31.53% of the data it buys fails this verification and is neither delivered nor billed to you. Every delivered email comes with a bounce probability. Every mobile number is checked with the carrier and, in the US and Canada, matched against the prospect's name.
On freshness, Dropcontact recomputes on every request, which helps catch job or company changes. FullEnrich depends on how fresh its providers' data is, but verifies each data point at delivery.
On compliance, both vendors state that they store no contact database and only process data on demand. Dropcontact emphasizes GDPR compliance "by design". FullEnrich lists GDPR, CCPA, and SOC 2 Type II certification, with a public trust center.
On geography, Dropcontact works in France and internationally with no database size limit. FullEnrich picks its providers based on the prospect's country to maximize the find rate.
Which tool to choose for your use case
If you're cleaning and enriching an existing CRM, especially in France and Europe, with strict GDPR requirements, go with Dropcontact, starting at €24 per month billed annually, and add the CRM subscription if your sales team works in HubSpot or Pipedrive.
If you prospect by phone, or target markets where a single provider covers your prospects poorly, go with FullEnrich. Budget 10 credits per mobile number found and use its calculator to pick the right tier.
