zoom.us - Email Domain Verification & Deliverability Report

Zoom Video Communications (zoom.us) is a leading video conferencing and collaboration platform headquartered in San Jose, California. Zoom became a household name during the COVID-19 pandemic and continues to serve hundreds of millions of users for video meetings, webinars, phone, and team chat. The company has expanded beyond video into a comprehensive workplace collaboration platform.

The zoom.us domain implements email authentication with SPF, DKIM, and DMARC enforcement. Zoom is heavily targeted by phishing attacks impersonating meeting invitations, recording notifications, and account security alerts. These "Zoom-bombing" and credential-stealing campaigns make strong domain authentication essential for the brand's integrity.

Email verification against zoom.us returns definitive accept/reject responses for individual mailboxes. The domain does not operate as catch-all. Zoom's mail infrastructure includes rate limiting and security monitoring on inbound SMTP connections.

For business partners communicating with Zoom employees, proper sender authentication improves deliverability. Zoom's corporate email filters evaluate incoming messages for SPF, DKIM, and DMARC compliance. Properly authenticated sending domains achieve more reliable inbox delivery at zoom.us.
