Why teams switch from Sendmarc to Red Sift OnDMARC
With Red Sift OnDMARC, you can identify misconfigurations in real-time, achieve enforcement faster, and future-proof your stack beyond core DMARC.
Teams want speed to enforcement, deeper visibility, and protection that scales without adding manual overhead.
OnDMARC automatically flattens your SPF records—unlike Sendmarc’s manual aggregator—so your mail is always delivered.
Get your logo next to every email you send to improve open rates by 39% and boost brand recall by 44%.
Red Sift goes beyond basic DMARC with an embedded LLM assistant for faster remediation and DNS monitoring that spots attacks like SubdoMailing.
Moving from Sendmarc to Red Sift OnDMARC is straightforward. Our Customer Success engineers walk you through each stage, from setup to fine-tuning, ensuring DMARC, SPF, DKIM, BIMI, and MTA-STS are fully optimized—without disrupting email flow or deliverability.
Unlike other DMARC providers, OnDMARC’s built-in AI assistant reduces manual effort by delivering instant, actionable guidance. Real-time notifications surface misconfigurations, authentication gaps, or unusual activity so teams can resolve issues without delay.
Proactive monitoring of the DNS layer (the foundation DMARC relies on) helps stop attacks that exploit forgotten domains or subdomains, such as SubdoMailing. Red Sift is the only vendor offering this layer of defense today.
One of Red Sift OnDMARC's key differentiating features is Red Sift Radar, our skilled-up LLM that frees up your team and eliminates manual work by combining deep cybersecurity intelligence with real-time AI analysis.

I find Red Sift OnDMARC to be extremely easy to set up and get running, which is a huge benefit as it allows for a smooth start without much hassle. The service's DMARC offerings have been indispensable since 2021, primarily for managing SPF records and enhancing domain impersonation security. [...] My high level of satisfaction is reflected in my likelihood to recommend it to others, as evidenced by giving it a perfect ten on the recommendation scale.
OnDMARC is straightforward to set up and begin using. Its standard features are more comprehensive than those offered by other solutions. For us, the main deciding factor was that dynamic SPF record services are included by default. Previously, we frequently encountered the issue of reaching the maximum limit of 10 SPF records, but with OnDMARC, this is no longer a concern.
The support team was prompt and well-informed. The interface is user-friendly and easy to navigate. Dynamic Services—particularly the SPF management—proved to be extremely valuable, helping us overcome SPF record length limitations effectively.
I find Red Sift OnDMARC incredibly easy to set up, thanks to the extensive and quick support provided by their team, always ready and standing by whenever we needed to progress. The platform excels at protecting our emails from any type of spoofing, ensuring the security of our organization is maintained and improved against continually evolving challenges.
Which should I choose?
Both Red Sift OnDMARC and Sendmarc deliver strong DMARC management capabilities.
- Sendmarc suits MSPs that need multi-tenant control and white-label flexibility.
- Red Sift OnDMARC is built for organizations ready to go further—automating enforcement, enriching insight, and integrating domain protection across their broader security stack. With embedded AI guidance, DNS monitoring, and intelligent data enrichment, it’s the natural choice for enterprises looking to scale security without adding complexity.
That’s the key difference: where Sendmarc stops at DMARC, Red Sift builds beyond it.
For enterprises, DMARC is the foundation and not the finish line. As priorities expand to DNS hygiene, lookalike detection, and brand protection, Sendmarc users will need additional vendors—creating cost, delay, and fragmentation.
Red Sift offers a unified platform that brings it all together:
- OnDMARC – for authentication and enforcement
- DNS Guardian – for DNS hygiene and misconfiguration detection
- Brand Trust – for identifying and removing lookalike domains
With over 40 years of email security expertise and proven G2 leadership, Red Sift helps enterprises secure their domains end to end—without extra headcount or complexity.
