The price you see is the price you pay
Many DMARC platforms publish their first one or two tiers and quote everything above them. Once your domain count or message volume grows, you face a sales cycle, a tier upgrade or a “contact sales” quote. EasyDMARC, for example, publishes two DMARC plans and quotes the tiers above them, and Red Sift publishes a price for OnDMARC Express alone (see EasyDMARC's pricing page and Red Sift's pricing page, checked 19 October 2026). Without published prices you cannot estimate the cost of service upfront, so the conversation starts from the vendor's figure.
ShieldMarc publishes every tier including the expansion bucket. Need more than 100 domains? The price is £40/month per expansion bucket (50 domain slots each). Posted, predictable, no negotiation needed. No metered overage fees. No surprise invoice the month your volume spikes. If you are consistently over your plan for three months in a row, sales reaches out and you decide the next move together.
Enterprise is for formal requirements: a contractual SLA, dedicated regional hardware hosting, or a compliance framework your auditor requires. Adding domains alone does not move you onto it. MSP covers up to 100, and expansion buckets take you well beyond that, so you can work out what ShieldMarc costs before you talk to anyone.
We can hold these prices because we run our own stack. ShieldMarc operates its own database, authentication and monitoring infrastructure rather than renting them from third-party managed platforms, so there is no managed-platform fee to pass on to you. How a modern stack shapes our DMARC pricing.
How we compare
ShieldMarc vs the typical DMARC monitoring platform, at each tier. One table, one scan. We compare how competitors price, not their prices, which change often: pricing models were checked on each vendor's own pricing page on 19 October 2026, and features at the most recent review (August 2026).
| Feature | Typical competitor | ShieldMarc |
|---|---|---|
| Free tier | ||
| Domains | 1 | 1 |
| Data retention | 10 days | 1 year |
| AI threat analysis | Paid only | Threat model only (AI on paid plans) |
| Free security tools 4 include plain-English AI explanations | Limited | 20 tools |
| First paid tier | ||
| How it is priced Checked on each vendor's pricing page, 19 October 2026 | Published entry tier, usually in USD or EUR, sized by domains and mail volume | Flat, published in GBP: £50/mo (annual, 25 domains) |
| Domains included | A few | 25 |
| Monthly message volume Competitor tiers are priced partly on mail volume | Capped by tier: more mail means a higher tier | 1,000,000 |
| Analysis engine We run both: our own threat model enriches the context, then AI reasons over it | Varies: some add AI agents on higher tiers (checked 20 October 2026) | Proprietary threat model + AI |
| SSL monitoring | Typically not included in DMARC tier | All 25 domains |
| DNS, DNSSEC, MTA-STS, TLS-RPT, CAA, lookalike | Partial or add-on per platform | All included on paid tiers |
| Top published tier MSP scale | ||
| How 100 domains are priced dmarcian and EasyDMARC quote above their published tiers, and Valimail quotes every paid tier (checked 19 October 2026) | Custom quote (sales-led) | Published: £100/mo (annual) |
| Monthly message volume Competitor tiers are priced partly on mail volume | Set by tier, then custom pricing | 5,000,000 (no hard cap) |
| Overage handling | Hit a cap, move up a tier or talk to sales | No hard cap, 3-month grace, no surprise billing |
| Pricing transparency | Published rates end here; everything above is custom quote | Published, including expansion (+50 domain slots for £40/mo) |
| Team members Checked on each vendor's pricing page, 19 October 2026 | Included, often unlimited at this tier | Unlimited |
| Brand TLD grouping | Not advertised | Included |
| Enterprise tier | ||
| What Enterprise means ShieldMarc Enterprise is for formal requirements, not for volume | Triggered by volume caps on the published tier: outgrow the listed plan and the next step is a quote. | Triggered by formal SLA, regional hardware hosting, or specific compliance frameworks. Standard scale stays on published MSP + expansion buckets. |
| Can you estimate your cost upfront? | Often not: where published pricing stops at a tier, everything above it needs a quote. | Yes, for every standard case. Published MSP + £40/bucket covers any volume or domain count. Enterprise quote is only for SLA/hosting/compliance specifics. |
How each competitor prices comes from its own public pricing page, checked on 19 October 2026: EasyDMARC's pricing page, dmarcian's pricing page and Valimail's pricing page. We describe pricing models rather than quoting competitors' prices, because those change often, so check current prices with each vendor.
Full side-by-side comparisons: ShieldMarc vs EasyDMARC · vs dmarcian · vs Valimail
Free trial: New accounts start with a 30-day free trial: 10 domains, 1 team member and every monitor type. No credit card required. One trial per organisation.
Money-back guarantee: Whenever you start an annual plan (converting from a free trial, or switching up from monthly), the 30 days run from the date you pay. Cancel within 30 days of that annual payment and we refund it in full, no questions asked.
Annual billing: Pay annually and save up to 29%. Annual plans are billed upfront for the full year.
Data retention: All plans include 1 year of data retention for DMARC reports and changelogs. Uptime check results are kept for 90 days.
Monthly messages (no hard cap, no surprise billing): We do not count messages against your plan, so spoofed mail sent as your domain cannot use up your allowance and you are not penalised for being targeted. If you go over, nothing breaks: reports continue to parse, dashboards stay live, alerts keep firing. We do not charge overage fees. If you are consistently over your plan for three months in a row, a sales contact will reach out to talk through the options. Your invoice never changes without a conversation first.
Migrating from NCSC Mail Check: All plans include DMARC aggregate report processing. The Starter plan covers one domain free. Professional covers 25. See our migration guide for step-by-step instructions.
Downgrade: If you downgrade, resources beyond your new plan limits are suspended (not deleted). Upgrade again to restore them.
VAT: ShieldMarc Ltd is not currently registered for VAT, so no VAT is added at checkout: you pay the price shown.
*MSP expansion bucket: MSP includes 100 domain slots and 5 million DMARC messages per month. Need more? Each expansion bucket at £40/month adds another 50 domain slots. All tools, monitors and team seats remain unlimited.
Brand protection (MSP plan): TLD variants of the same brand (e.g. example.com and example.co.uk) count as a single domain slot at no extra cost on the MSP plan. We encourage MSPs to monitor every defensive and alternate TLD for each client. It strengthens their security posture without inflating your bill.
Enterprise: For a contractual SLA, dedicated regional hosting or a specific compliance framework, with a dedicated account manager. More domains or more mail alone do not need it: MSP and expansion buckets cover those. Contact us for a quote.
