Strict DMARC Enforcement from Google
What’s Changing?
This month Google has announced stricter enforcement of DMARC (Domain-based Message Authentication, Reporting & Conformance) policies for Gmail senders. This means that emails failing DMARC checks may be rejected or flagged as spam, significantly impacting deliverability for businesses that haven’t implemented proper authentication.
According to dmarcwise.io, these changes are part of Google’s ongoing effort to reduce phishing and spoofing attacks, ensuring that only verified senders can reach inboxes.
Why DMARC Matters

DMARC works alongside SPF and DKIM to verify that emails are genuinely from your domain. Without DMARC:
- Your emails risk being marked as spam or rejected entirely.
- Your domain is vulnerable to spoofing and phishing attacks.
- You lose visibility into who is sending emails on your behalf.
Implementing DMARC not only improves deliverability but also strengthens your brand’s security posture.
Google’s New Requirements
Gmail will now require:
- Valid SPF and DKIM records for all sending domains.
- A published DMARC policy (at least
p=none, but stricter policies recommended). - Alignment between “From” headers and authenticated domains.
Failure to comply could result in email rejection or reduced trust scores.
