The 7 best Red Sift OnDMARC alternatives in 2026
Where to look if OnDMARC's contact-sales tiers and separate product SKUs don't suit.
Figures verified against each vendor's public pricing page, July 2026.
Red Sift OnDMARC is one of the strongest names in this market: UK-headquartered, certified to ISO 27001 and SOC 2 Type II, with mature MSP infrastructure and hosted record management including Dynamic SPF. Two things send buyers looking elsewhere: only the entry price is published (Express from ~£7.20/mo billed annually; everything above is contact-sales), and adjacent capabilities are separate products: lookalike detection sits in Brand Trust and certificate monitoring in a separate SKU. Jurisdiction is not the issue here, since Red Sift is as UK as they come. It comes down to pricing model and bundling, and that's what the list below compares.
Contact-sales above Express
One published 'starting at' price; the tiers a growing estate actually needs, including MSP scale with its 25/50 active-domain gates, are quoted.
Separate product SKUs
Lookalike detection (Brand Trust) and certificate monitoring are separate purchases, so the full protective basket costs more than the DMARC line item.
No permanent free tier
OnDMARC offers a 14-day trial rather than a free plan, so ongoing zero-cost visibility needs a different tool.
1. ShieldMarc
Our product, read criticallyBest for: UK teams and MSPs that want flat, published pricing and whole-domain monitoring in one place
Full disclosure: ShieldMarc is our product, so judge this entry accordingly. Every figure here is published on our pricing page. Paid plans run each DMARC report row through a proprietary threat model with on-demand AI reasoning on top, and every plan bundles lookalike-domain scanning plus SSL, DNS, DNSSEC, MTA-STS, TLS-RPT, CAA and uptime monitoring rather than selling them as separate products. Pricing is flat: no per-domain steps, no volume-triggered tier jumps, a 3-month overage grace instead of surprise billing.
- Pricing:
- £50/mo annual (Professional, 25 domains, 1M messages) or £100/mo annual (MSP, 100 domain slots, 5M messages); expansion buckets £40/mo
- Free option:
- Starter: permanently free, 1 domain, 10,000 messages/mo, 1-year retention, 20 free tools
- Domains (first paid tier):
- 25 (Professional)
- Base:
- UK owned, EU hosted, UK hosting on request
2. dmarcian
Best for: Teams that value protocol heritage and deep DMARC education
One of the longest-running DMARC platforms, employing several of the protocol's original authors, with excellent documentation and deployment guidance. The trade-off is step-function pricing: outgrowing a tier means a roughly 10x jump (Basic to Plus), and the parent company is US-based, which matters for UK buyers weighing the US CLOUD Act. Verify at dmarcian.com/pricing.
- Pricing:
- Basic ~£19/mo (2 domains, 100k msgs), then Plus ~£192/mo (8 domains, 1M), then Enterprise ~£480/mo (15 domains, 5M); USD list prices, converted at ~£1 = $1.25
- Free option:
- Personal: free, 2 domains, 1,250 messages/mo, 1 user
- Domains (first paid tier):
- 2 (Basic)
- Base:
- US-headquartered, EU subsidiary (dmarcian EU BV)
3. EasyDMARC
Best for: Small estates that want a polished UI and guided setup
A capable platform with one of the most polished interfaces in the market and a large customer base. Economics are per-domain: Plus and Premium cap at 2 and 4 domains, so costs climb quickly across a multi-domain estate, and higher message volumes go through a sales conversation. Verify at easydmarc.com/pricing.
- Pricing:
- Plus €44.99/mo (2 domains) or Premium €89.99/mo (4 domains); larger volumes via sales
- Free option:
- Free: 1 domain, 1,000 messages, 1 user, 14-day history
- Domains (first paid tier):
- 2 (Plus)
- Base:
- US-incorporated (Delaware), founded in Armenia
4. PowerDMARC
Best for: Budget-first buyers starting small who can live with volume-triggered steps
A fast-growing suite with a very low entry price and broad hosted services (hosted SPF/DKIM/BIMI, MTA-STS). Watch the pricing mechanics: the Basic tier's price steps up as your compliant-email volume crosses thresholds, and Enterprise, API and Partner tiers are all custom-quote. Verify at powerdmarc.com.
- Pricing:
- Basic from ~£6.40/mo (5 domains) with in-tier price steps as compliant volume crosses 100k/200k; Enterprise, API and Partner plans custom-quote; USD list prices
- Free option:
- Free: 1 personal domain, 10,000 compliant emails/mo, 10-day history
- Domains (first paid tier):
- 5 (Basic)
- Base:
- US corporation (MENAINFOSEC, Inc., Delaware), offices in US/Armenia/UAE/Oman/Qatar
5. Valimail
Best for: Large enterprises that want a managed, sales-led rollout
A well-regarded enterprise platform with strong automation (hosted SPF/DKIM/DMARC) and a free Monitor tier that gives real visibility. The model is sales-led: published entry pricing starts around £3,900/year and everything else is quoted, so smaller teams face a procurement cycle for what self-serve platforms sell online. Verify at valimail.com/pricing.
- Pricing:
- Enforce Starter from ~£3,900/year; everything above is custom via an account team; USD list prices
- Free option:
- Monitor: free sender-intelligence dashboards
- Domains (first paid tier):
- Quoted per contract
- Base:
- US-based
6. Sendmarc
Best for: MSPs already inside its partner programme
A partner-first platform (founded 2018) with strong MSP machinery and unlimited domains on paid tiers. The catch for direct buyers: no pricing is published anywhere on its site, so you learn the cost only through a sales cycle, and the trial is 21 days rather than a permanent free plan. Verify at sendmarc.com.
- Pricing:
- No pricing published: every paid tier is quote-based
- Free option:
- 21-day trial (1 domain, 5k emails/mo)
- Domains (first paid tier):
- Unlimited on paid tiers
- Base:
- South African-founded group, HQ Johannesburg; US/NL/AR offices
7. parsedmarc (open source)
Best for: Engineering teams happy to run and maintain their own stack
The standard open-source answer: a Python tool that parses DMARC aggregate/forensic reports and ships them to Elasticsearch with Grafana/Kibana dashboards. Free and private, but you own the mailbox ingestion, parsing pipeline, dashboard upkeep and alerting yourself. There is no support, SLA or threat analysis. Docs at domainaware.github.io/parsedmarc.
- Pricing:
- Free, Apache-licensed; you pay in hosting and engineering time
- Free option:
- Entirely free, self-hosted
- Domains (first paid tier):
- Unlimited
- Base:
- Self-hosted wherever you run it

How to choose
- Price the whole basket. If you need DMARC + lookalike + certificate monitoring, compare OnDMARC's multi-SKU total against platforms that bundle them (ShieldMarc includes lookalike, SSL, DNS, DNSSEC, MTA-STS, TLS-RPT, CAA and uptime on paid tiers).
- If certifications are the requirement, keep Red Sift and Valimail on the shortlist. ShieldMarc holds Cyber Essentials with SOC 2 and ISO 27001 on the roadmap, which may or may not satisfy your procurement today.
- Ask every vendor for published MSP pricing before entering a partner conversation: ShieldMarc publishes it (£100/mo annual, 100 slots); OnDMARC and Sendmarc quote it.
- Staying UK is possible either way: ShieldMarc (UK owned, EU hosted, UK on request) and Red Sift (UK HQ) both satisfy a UK-preference constraint; the difference is pricing transparency and bundling.
Frequently asked questions
What is the best alternative to Red Sift OnDMARC?
For UK buyers who want published flat pricing and bundled whole-domain monitoring, ShieldMarc is the closest counter-model (and also UK-owned). For enterprise sales-led with certifications, Valimail. For protocol heritage, dmarcian. For zero budget, parsedmarc.
Is there a cheaper alternative to OnDMARC?
Express's published entry (~£7.20/mo annual) is competitive, but scale tiers are quoted. For a 25-domain estate, ShieldMarc Professional is a published £50/mo annual all-in; for 100 domains the MSP tier is £100/mo. Both include monitoring OnDMARC sells as separate products, so the comparable total is usually lower.
Is there a free alternative to OnDMARC?
Yes. OnDMARC has only a 14-day trial; ShieldMarc Starter is permanently free (1 domain, 10,000 messages/mo, 1-year retention), Valimail Monitor is free for visibility, dmarcian has a free Personal tier, and parsedmarc is free open source.
Is there another UK-based DMARC platform besides Red Sift?
Yes. ShieldMarc is UK-owned and run, EU-hosted by default with UK hosting on request. Both companies are UK-based, so the choice comes down to pricing model, bundling and certification requirements rather than jurisdiction.
