2Fifteen Tech | DMARC Management
Email is the backbone of business communication, but it's also one of the most exploited attack vectors. Domain spoofing and phishing attacks cost organizations millions annually and damage brand reputation. 2Fifteen Tech provides fully managed DMARC services to protect your domain, ensure email deliverability, and meet evolving compliance requirements from major email providers.
What is DMARC?
DMARC (Domain-based Message Authentication, Reporting and Conformance) is an email authentication protocol that verifies emails claiming to come from your domain actually do. It works alongside two other technologies—SPF and DKIM—to create a layered defense against email fraud.
Think of it this way: SPF confirms the mail server is authorized to send on your behalf. DKIM adds a digital signature proving the message hasn't been tampered with. DMARC ties them together and tells receiving servers what to do when authentication fails—accept it, quarantine it, or reject it entirely.

New Compliance Requirements
Major email providers have implemented stricter authentication requirements to combat fraud and improve user security. Organizations that don't comply risk having legitimate emails blocked or sent to spam.
Google & Yahoo
Organizations sending more than 5,000 emails per day to Gmail or Yahoo addresses must implement SPF, DKIM, and DMARC. This requirement went into effect in February 2024.
Microsoft
Similar requirements apply for high-volume senders to Hotmail, Live, and Outlook addresses. Microsoft continues to strengthen authentication standards across their email platforms.
Beyond email provider mandates, DMARC helps organizations meet broader compliance requirements including GDPR, HIPAA, PCI DSS, and other industry regulations that require protection of sensitive communications.
