Red Sift is cheaper to start and better at BIMI. The question is what happens at your fifth domain.
Both platforms automate enforcement and host MTA-STS and BIMI records, and both let you sign up without talking to anyone. Their Express tier undercuts ours and their VMC workflow beats ours outright — but Express has two ceilings, and everything above it is a quote.
Free plan: 2 domains, no card, no expiry · Trial: card required, billed on day 15 unless you cancel · 14-day money-back on new paid plans
Express is cheap. Express is also capped twice.
Four domains and a million emails a month, whichever you hit first. Past either ceiling the published pricing stops and a sales conversation starts.
Above four domains OnDMARC’s published pricing ends: Essentials, Enterprise and Premier are all quote-only. Ours keeps going on the pricing page — Growth to fifteen, Professional to twenty-five, then Partner and a published Enterprise floor.
List prices, monthly, at the stated domain count. Plans are not like for like: see the matrix for what each includes.
Four things, not thirty-seven rows.
Both products automate enforcement, host records and parse aggregate reports into per-sender detail. Listing those as wins would be padding. These are the differences that change the decision.
A price on every tier, not just the entry one
Express is published and cheap. The tier above it is quote-only, and a growing estate can reach either of Express’s two caps quickly.
ARC monitoring and the policy simulator
ARC separates a forwarded message from a spoof; the simulator models a move to p=reject against last month’s real traffic. Neither is documented for OnDMARC.
Two ceilings versus one
Express caps on domains and on email volume, so a campaign can push you off it without your estate changing at all. Ours caps on domains only — sending volume is never metered at any tier.
A published partner program
If you resell, our partner tiers are on the pricing page at a rate you can model a margin against before any conversation. Theirs is a partner relationship, not a price list.
Where Red Sift OnDMARC is the better buy.
If none of these is you, switching costs an afternoon and no data: DMARC reports are generated by receiving providers, so migrating is a change to one DNS record. Ask and we will do the bulk of it at no charge, including running both platforms in parallel while you decide — the offer and the details are below.

Feature by feature.
“Not documented” means we could not find it stated in Red Sift OnDMARC’s public materials, not that it is absent. Competitor facts verified from public sources in September 2026— if something here is out of date, tell us and we will correct it.
The questions that decide it.
At the entry tier, yes: Express is published at $9/mo billed annually against our $29/mo Protect. Two things qualify that. Express is capped at four domains and one million emails a month, so one campaign can push you off it without your estate changing. The tier above Express is quote-only. Our next two rungs are published at $69 and $99.
Run both for two weeks.
Point the same domain’s reports at both platforms — DMARC lets you send to more than one address. Two weeks of side-by-side data settles this better than any comparison table, including this one.
