How to find company email domain
Describe your target market or industry
Add your target market or industry into Sculptor. Clay's company database compiles a matching list with company name and email domain per row.
Sculptor builds the matched company list
Sculptor scans Clay's B2B company data, filtering by the industry or market you specified, and assembles a table of matching companies. Each matched row includes the company name and its email domain, ready for enrichment or outreach.
Get company names and email domains ready to use
The finished table has company name and email domain for each matched row. Push to HubSpot or Salesforce, or export to your outbound tool of choice.
Why Clay for finding company email domain
Company domain sourced from one B2B dataset
Pull a ready-to-use list of company names and domains in minutes. Clay's B2B company database filters by industry, headcount, funding stage, tech stack, and location so every matched row arrives domain-ready.
Multi-provider waterfall resolves hard-to-find domains
Get a resolved domain even when one source comes up empty. Clay waterfalls across multiple providers, including ZoomInfo and Crunchbase, and only charges credits when a provider returns a confirmed match.
Claygent validates domains against live company sites
Avoid mismatched or stale domains before they reach your outbound tool. Claygent browses each company's website and flags domain mismatches, including companies that use multiple sending domains.
Push clean domain lists to your CRM or sequencer
Send verified company names and domains directly to HubSpot or Salesforce, or route them into Smartlead or Instantly for outbound. Auto-refresh on schedule keeps your records current without manual re-exports.
With Clay, we more than doubled our enrichment coverage from low 40% to high 80%
Frequently asked questions
How does Sculptor find a company's email domain?
Sculptor searches a database of millions of company profiles by your target industry or description keywords, then runs waterfall enrichment across 50+ data providers in sequence to resolve each company's email domain. It stops at the first provider that returns a verified match, so you only use credits on the source that delivers. Your table populates with company name and verified email domain in seconds.
How accurate are the company email domain results?
Coverage typically lands between 30% with a single provider and 80% or higher when Clay's waterfall cycles through multiple sources. Every returned domain passes a validation check before it reaches your table, and you can set the validation strategy to Conservative, Balanced, or Aggressive depending on your quality bar. Industry benchmarks from providers like Hunter and Clearbit align with these ranges for B2B domain resolution.
Can I find company email domains for a whole list at once?
Yes. Paste a list of company names directly into Sculptor, upload a CSV, or pipe rows from an existing Clay table. Sculptor enriches every row in parallel and returns verified domains for the entire batch. From there, push the results to HubSpot, Salesforce, or Pipedrive, or export as a CSV to feed outbound sequences or ad audience uploads.
Is it legal to collect and use company email domains for outreach?
CAN-SPAM governs commercial email in the U.S. and applies to B2B messages with no exemption. Every email must include a valid physical address, a working unsubscribe link, and truthful header information. Penalties can reach $53,088 per violation as of January 2025. In the EU, GDPR allows B2B outreach under the legitimate interest basis, but you must document that interest and honor data subject requests promptly.
Rules vary by country and state, so always check the regulations for your jurisdiction before launching campaigns.
