A Red Sift OnDMARC alternative for UK SMEs
How SealedMail compares to Red Sift OnDMARC: an enterprise platform versus a right-sized, flat-price managed service for UK SMEs.
Weighing up Red Sift OnDMARC? Here is an honest look at how SealedMail differs, who each option suits, and how to choose. We have tried to be fair: Red Sift OnDMARC is a good product for the right buyer.
Red Sift OnDMARC is an automated, enterprise-grade email-security platform (part of a broader product suite) with sales-led pricing, used by larger organisations. SealedMail takes a deliberately different approach: rather than a dashboard you log into, you point your DMARC and TLS-RPT reports at us and receive one plain-English report by email every week, read and interpreted by a UK specialist. No dashboard, no logins, a flat GBP 49 per domain per month on a rolling subscription.

When Red Sift OnDMARC is the better choice
For enterprises with many domains, high email volumes and an in-house security team to run the platform, Red Sift OnDMARC is a capable, automated and well-regarded choice. It is built for that scale.
When SealedMail is the better choice
If you do not have someone who will reliably log into a dashboard, interpret DMARC aggregate reports and act on them, a managed report-by-email service removes that failure point - the most common reason DMARC projects stall at p=none. SealedMail is built for UK organisations, especially in regulated sectors like law, accountancy, healthcare and charities, that want the reporting read, explained and turned into a clear weekly action list at a flat price, with no platform to learn.
How to decide
Ask one question: will someone actually read and act on the reports? If yes, and they are comfortable with the technical detail, a self-serve platform like Red Sift OnDMARC can be excellent value. If not - or you would simply rather a specialist did it for you - that is exactly what SealedMail is for.
Either way, the best first step is to check where your domain stands today (free, no sign-up), and see our UK Email Impersonation Report for why this matters. Ready to switch? See pricing.
