The email provider and tech stack task reads each domain's public MX and SPF records to name the mail provider, such as Google Workspace or Microsoft 365. No email is sent and no mailbox is contacted.
The email provider and tech stack task's CMS and CDN hints are fingerprints from public headers and HTML, so they can miss or misread custom setups. Treat them as hints for lead qualification, not a full audit.
The Website & Email Domain Checker charges $0.008 per valid domain checked. Invalid or non-resolving domains are free, and a run stops at your spend limit.
Save the Website & Email Domain Checker task to your account, then add a weekly schedule in Apify Console, or call the run-sync-get-dataset-items API endpoint from n8n, Make, Zapier or Clay.
