Enter any email address to instantly see whether its domain belongs to a well-known free consumer webmail provider (like Gmail or Yahoo) or appears to be a custom business domain — a quick, single-address signal that's useful for lead qualification and outreach triage.
In B2B sales and marketing, whether a lead signs up with a free consumer webmail address or a custom company domain is a widely used, low-effort qualifying signal — someone using dana@acme.com is more likely to be reachable through a verifiable employer, while someone using dana92@gmail.com gives you no confirmation of where they work at all. It's not a judgment on the person, just a data point that many lead-scoring and CRM systems weight automatically. None of this means a free-domain lead is a bad one — plenty of real decision-makers, freelancers and small business owners use personal email day to day — it's simply one more piece of context to fold into however your team already prioritizes outreach.
This tool checks the domain of any address you enter against a list of the most widely used free consumer email providers worldwide — Gmail, Yahoo, Outlook/Hotmail/Live, iCloud, AOL, ProtonMail and several others — and reports a simple business-or-free verdict along with the specific domain matched.
A custom domain isn't automatically proof of a real, active business — anyone can register a domain and set up email on it cheaply, including for a side project, a personal brand, or a domain that was purchased but never developed further. Likewise, some legitimate freelancers, small business owners and professionals genuinely prefer a free provider for cost or convenience reasons. Treat this as one input among several, not a standalone verdict on legitimacy.
No — it only means the domain isn't on the list of common free consumer webmail providers. Verifying that a company is legitimate and active requires additional checks, like confirming the domain has a working website or checking a business registry. It's best read as a quick triage signal early in a workflow, not a final qualification decision on its own.
The list covers the most widely used global and regional free providers, but new and smaller regional webmail services do exist that may not be included. If you spot a common one missing, treat an unrecognized domain as inconclusive rather than automatically 'business'.
This tool is built for checking one address at a time in detail. For a full list, use the Email Domain Extractor first to see your list's unique domains, then spot-check any you're unsure about here.
That's a judgment call for your own process — this tool only surfaces the signal; how much weight to give it in lead scoring, outreach prioritization, or account routing is up to your team's criteria.
No — it only classifies the domain type. Pair it with the Email Validator or Deliverability Tester if you also need to confirm the address is properly formatted and has active mail servers.
