Email Provider & DNS Checker
Find out which email provider a company uses — Google Workspace, Microsoft 365, Zoho, IONOS, STRATO and 25+ others — and check its email authentication setup (SPF, DMARC, DKIM, MTA-STS, BIMI) for a whole list of domains at once.
It only reads public DNS records. No website scraping, no login, no proxy, no personal data.
What you get for each domain
| Field | Example | Meaning |
|---|---|---|
provider | Microsoft 365 | Mail host detected from the MX records |
mailboxProviderBehindGateway | Google Workspace | If the MX points to a security gateway (Proofpoint, Mimecast, ...), the real mailbox host taken from SPF |
mxHosts | ["sap-com.mail.protection.outlook.com"] | MX records, by priority |
spf, spfIncludes | v=spf1 include:_spf.google.com ~all | SPF record and its includes |
dmarc, dmarcPolicy | reject | DMARC record and policy (none, quarantine, reject) |
dkimFound | ["selector1","selector2"] | Common DKIM selectors that exist |
mtaSts, bimi | true | MTA-STS and BIMI records present |
error | Domain does not exist | Set when the domain cannot be checked |
Use cases
- Cold email & lead lists: split prospects by Google Workspace vs Microsoft 365 before outreach — the two need different sending and warm-up setups.
- Sales intelligence: a company on Microsoft 365 or Google Workspace is a signal for selling add-ons, migrations or security tools.
- Deliverability & security audits: find domains without DMARC, with
p=none, without MTA-STS, or without SPF. - AI agents: works as a tool through the Apify MCP server — give it domains, get structured JSON back.
Input
{"domains": ["apify.com", "https://www.sap.com/about", "info@zalando.de"],"checkDkim": true}
URLs and email addresses are accepted; the domain is extracted, www. and duplicates are removed.
Pricing
Pay per event: you pay only for domains that were checked successfully. Domains that do not exist or fail to resolve are free. There is no extra charge per run.
Notes and limits
- DKIM selectors are not public. The Actor probes about 15 common selectors, so an empty
dkimFounddoes not prove that DKIM is missing. - Provider detection uses MX hostnames. Domains with their own mail servers show
Other / self-hosted. - Results reflect DNS at the time of the run.
