Comparison

ShieldMarc vs Sendmarc

For UK MSPs weighing a partner-first platform against published, predictable pricing.

ShieldMarc is a UK-owned, EU-hosted alternative to Sendmarc for DMARC monitoring, with published flat pricing at £0, £49 and £99 per month (annual). Sendmarc publishes no pricing at all: every paid tier is quote-based, with no currency or figure shown anywhere on its site, so we cannot convert or compare list prices — buyers must go through a sales cycle to learn the cost. Sendmarc is a credible, partner-first platform founded in 2018 with genuinely strong MSP machinery and unlimited domains on paid tiers. Where ShieldMarc wins is price transparency, self-serve onboarding, a permanent free plan rather than a 21-day trial, broader monitoring (SSL, DNS, uptime) and on-demand AI analysis. Plan structure and limits below are from Sendmarc's public pricing page, verified July 2026; verify directly at sendmarc.com/pricing-page/.

Published pricing vs quote-only sales

Every Sendmarc paid tier — Premium, Microsoft/Google & Yahoo Compliance, and Enterprise & Government — is priced “Get a quote”, with no currency or amount published anywhere on the site (verified July 2026). ShieldMarc prices are on the website: £0 / £49 / £99 per month (annual), plus published £39.99/mo expansion buckets. No quote cycle.

A permanent free plan, not a 21-day trial

Sendmarc's free tier is explicitly a trial: 1 domain, 5,000 emails/month, 1 portal user, 21 days of data history. ShieldMarc Starter is free for good: 1 domain, 10,000 messages/month, 1 year of data retention and 20 free tools with AI explanations.

Threat model + Claude AI

Paid ShieldMarc plans run every DMARC report row through our proprietary threat model, then a frontier Anthropic Claude model reasons on top, on demand only. Sendmarc markets no AI-assisted analysis or remediation features on its site as of July 2026.

Conclusion

Where ShieldMarc has an edge

  • Published pricing on every tier, including expansion buckets. Sendmarc publishes no figure for any paid tier — no currency, no amount — so you cannot budget without a sales cycle.
  • Self-serve onboarding in minutes with one DNS record change and a 30-day free trial, no card. Sendmarc's sales motion is quote- and partner-mediated.
  • A permanently free Starter plan with 1 year of data retention, versus Sendmarc's 21-day trial capped at 5,000 emails/month.
  • Paid-plan AI analysis combines our proprietary threat model with a frontier Anthropic Claude model, on demand only. Sendmarc markets no AI-assisted analysis.
  • Full external attack surface in one dashboard on paid tiers: DMARC, SPF, DKIM, SSL, DNS, DNSSEC, MTA-STS, TLS-RPT, CAA, domain expiry, uptime and lookalike. Sendmarc's scope stops at email authentication plus lookalike and breach detection.
  • UK owned, EU hosted by default, UK hosted on request — and we publish where your data lives. Sendmarc publishes no hosting regions and operates a US Delaware entity (Sendmarc Inc).
  • Public Trust page and minimal personal data by design, suitable for DPIA-heavy UK public sector buyers. Sendmarc's detailed security docs are gated behind an access-controlled trust centre.

Where Sendmarc stacks up

  • Compliance posture today: Sendmarc describes itself as SOC 2 Type II and ISO 27001 compliant. If your procurement requires those as hard gates now, that may be decisive; ShieldMarc's attestation roadmap starts with Cyber Essentials, then SOC 2/ISO 27001, with certification-grade controls documented on our public Trust page in the meantime.
  • Unlimited domains, email volume, portal users and data history on every paid tier — no published step-function caps once you are on a paid plan. ShieldMarc's published plans cap at 100 domain slots plus expansion buckets.
  • Hosted, delegation-managed DNS records and continuously maintained SPF flattening, plus BIMI management. ShieldMarc's SPF Flattener is manual today (Dynamic SPF is coming soon) and we do not ship hosted BIMI.
  • One of the most partner-first DMARC vendors: multi-tenant console, consumption-based On-Demand billing and native PSA integrations with ConnectWise, Autotask and HaloPSA. ShieldMarc has no PSA integrations today.
  • Dark-web Breach Detection is shipping today; ShieldMarc's dark web monitoring is still on the roadmap.
  • Longer track record (founded 2018) with a global footprint across five countries, SSO via Okta, Google Workspace and Microsoft 365/Entra on paid tiers, and a full API with SIEM integration support.
For full detail on our security posture, tenant isolation, audit logging and incident response see our Trust page. What personal data we hold (and do not hold) is set out in our Privacy Policy. For vendor assessments, DPIAs or procurement questionnaires, contact sales with the framework and we will respond with the relevant evidence — no gated trust centre, no access request. Both platforms implement the same DMARC standard, published as RFC 7489, obsoleted in May 2026 by DMARCbis (RFC 9989), so the decision comes down to pricing transparency, hosting, monitoring breadth and how much of the buying and onboarding process is self-serve.

Frequently asked questions

What is an alternative to Sendmarc for DMARC monitoring?

ShieldMarc is a UK-owned, EU-hosted alternative to Sendmarc. It parses the same DMARC aggregate and forensic reports but publishes flat pricing (£0, £49 or £99 per month on annual billing) where every Sendmarc paid tier is quote-based, and it adds SSL, DNS, DNSSEC, uptime and domain expiry monitoring plus a proprietary threat model with Claude AI analysis on demand. Other alternatives include dmarcian, EasyDMARC and Valimail. Sendmarc remains a strong choice for partner-led MSPs that want unlimited-domain paid tiers and native PSA integrations.

Is ShieldMarc cheaper than Sendmarc?

We cannot compare list prices, because Sendmarc does not publish any: as of July 2026 every paid tier on sendmarc.com is priced “Get a quote”, with no currency or amount shown. What you can compare is certainty. ShieldMarc's cost is knowable before you speak to anyone: £49 per month (annual) covers 25 domains, about £1.96 per domain, and the MSP plan covers 100 domain slots for £99 per month, about £0.99 per domain, with published £39.99 per month expansion buckets beyond that. Sendmarc's free tier is also a 21-day trial, while ShieldMarc's Starter plan is permanently free for one domain.

Which is better for UK MSPs: Sendmarc or ShieldMarc?

It depends on how you buy and bill. Sendmarc has genuinely strong MSP machinery: a multi-tenant console, consumption-based On-Demand billing, PSA integrations with ConnectWise, Autotask and HaloPSA, and unlimited domains on paid tiers — but pricing is quote-based and it publishes no hosting regions. ShieldMarc gives UK MSPs published per-client economics (£99 per month for 100 domain slots, with brand TLD grouping so alternate TLDs count as one slot), UK ownership with EU hosting by default and UK hosting on request, and SSL, DNS and uptime monitoring in the same bill. If predictable published cost and UK data sovereignty decide it, choose ShieldMarc; if PSA-integrated consumption billing decides it, Sendmarc stacks up well.
