Alternatives to the leading DMARC platforms
Honest lists, verified against each vendor's public pricing page. Each guide covers seven options, including a free open-source route, compared on published pricing, free tiers, domain limits and UK/EU hosting. Yes, ShieldMarc appears in each list; it's clearly labelled as ours, and the competitor facts stand on their own.
Best dmarcian alternatives
Deep DMARC heritage, but pricing steps roughly 10x per tier (~£19 → ~£192 → ~£480/mo) and the parent company is US-based.
Best EasyDMARC alternatives
Polished UX; Plus and Premium cap at 2 and 4 domains, so per-domain costs climb across larger estates.
Best Valimail alternatives
Strong enterprise automation behind a sales-led motion. Published entry is ~£3,900/year and everything above is quoted.
Best PowerDMARC alternatives
Very low entry price, but in-tier volume steps at 100k/200k messages and quote-only Enterprise, API and Partner plans.
Best Red Sift OnDMARC alternatives
UK-headquartered and strongly certified; only the entry price is published, and lookalike/certificate monitoring are separate products.
Best Sendmarc alternatives
Strong MSP machinery, but no pricing published anywhere. Every paid tier is a sales conversation.
Best Mimecast DMARC Analyzer alternatives
The former DMARC Analyzer, now inside Mimecast's enterprise portfolio, with no standalone published pricing.
