Find Names & Domains by Email Addresses use cases
Split a list of work emails into their parts with a simple regex - the local-part tokens plus the domain. For example s.chen@notion.so becomes s / chen / notion.so. It is a deterministic string split, not a lookup, so it is completely free and unlimited - no credits, no API.

Use Find Names & Domains by Email Addresses via the API and the MCP
Find Names & Domains by Email Addresses isn't tied to one surface. Every Derrick enrichment - this one included - runs in the web app and in Google Sheets, and is also exposed through the REST API and the MCP server, so you can run it from your CRM, your data pipeline, an AI assistant, or any no-code tool (Zapier, Make, n8n). Same credit cost everywhere, same data. API access is included from the PLUS plan up.
"This app saved me so much time and effort. Great for anyone looking to build a contact list or network at scale quickly. As a start-up it's been invaluable."
Alex Clark
Director | SaaS GTM Leader
"Working pretty nifty compared to Snov.Io. Price wise it does give a fair shake, and IMO better interface since it's google sheets."
David Sire
Mortgage Broker at Zero Point Mortgage
"Derrick is a very simple and user-friendly app to enrich your contacts database. Best thing: you can test it for free. And then the price is so low, it's a no brainer."
Etienne Grange
CEO Form'actions
"I have been using other expensive apps or freemium like phantombuster, but Derrick has replaced them all. I love the simplicity of the Google sheet add-in, but what is best is the efficiency it delivers."
Julien Walon Cohen

Michael Kim
SDR Team Lead at CloudScale

Dan Hughes

"Have tested over 10+ LI scraper apps, Derrick beats them all. Simple to use, accurate data, and affordable price."

Reverse email lookup is the inverse of the email finder workflow : you already have the email, you need the real name + company behind it. Most B2B teams hit this when triaging cold-inbound, deduplicating CRM lists, or qualifying webinar / lead-magnet signups. Most enrichment tools sell this as a separate API endpoint and meter it per call. Derrick reads the email column directly from your list, in the Derrick web app or in Google Sheets, and returns the verified first name + last name + company domain in the next cells - free and unlimited, with no credit consumed.
The main limit is structural : free-mail addresses (gmail / yahoo) where no company can be inferred from the domain itself stay blank - same outcome you'd get from any tool. See where this fits in the Derrick plan grid.
Do I need to install anything to use Find Names & Domains by Email Addresses?
+
No. Create a free account in the Derrick web app and Find Names & Domains by Email Addresses is there, nothing to install. Prefer Google Sheets? The add-on installs in one click and Find Names & Domains by Email Addresses appears in the Derrick sidebar. The same feature is also available via REST API and via the Derrick MCP server for Claude / ChatGPT.
Can I use Find Names & Domains by Email Addresses on a list of 1,000+ rows?
+
Yes - Find Names & Domains by Email Addresses runs as a batch job in the web app or in Google Sheets, with progress tracking and per-row credit accounting. The workflow scales linearly: 10 rows or 10,000 rows, the steps are identical and you can step away while it runs.
Where does the data behind Find Names & Domains by Email Addresses come from?
+
Derrick aggregates 10+ public-data sources (LinkedIn graph, company websites, registry data, web crawl, third-party providers) and runs a multi-source lookup for Find Names & Domains by Email Addresses. The first source that returns a confident match wins; if no source is confident enough, the cell is left blank rather than guessed.
Is Find Names & Domains by Email Addresses GDPR-compliant?
+
Yes. Derrick only enriches public data, doesn't store personal records beyond the duration of the lookup, and supports full deletion on request. The Sheets add-on runs inside Google's OAuth-protected environment so your data stays private to your account.
Can I trigger Find Names & Domains by Email Addresses automatically when I add a row?
+
Yes - set up a Google Sheets onEdit trigger (Apps Script, takes 2 minutes) so a new row in column A automatically runs Find Names & Domains by Email Addresses into column B. Pair with Zapier / Make / n8n to push CRM contacts directly into the sheet for hands-free enrichment.
