TL;DR: How to Simplify DMARC, SPF, and DKIM management with Red Sift
The challenge:
Managing DMARC, SPF, and DKIM is complex; manual DNS updates, 10-lookup SPF limits, configuration errors, and waiting 24 hours for DMARC reports slow down implementation and create security gaps.
The solution:
Red Sift OnDMARC simplifies email authentication through Dynamic Services—make one DNS change and manage all SPF, DKIM, DMARC, BIMI, and MTA-STS records directly in the OnDMARC interface. No more manual DNS edits or change requests.
Key features:
- Dynamic SPF: Bypass the 10-lookup limit without macros, ensuring deliverability across legacy systems
- Real-time testing: Investigate tool validates changes instantly—no 24-hour wait for reports
- Automated discovery: Finds all email sources, including shadow IT
- One-click authentication: Simplifies SPF/DKIM configuration with automatic updates when third-party services change
Results:
Organizations reach full DMARC enforcement in 6-8 weeks on average, eliminating manual errors, saving time, and protecting against phishing while improving email deliverability.
