Competitor pricing reflects publicly listed rates from leading DMARC monitoring platforms as of March 2026. Prices vary by provider. We encourage prospective customers to verify current competitor pricing independently.
Free trial: Early access testers get a 90-day free trial. After public launch, new users get a 30-day free trial. No credit card required. One trial per organisation.
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, changelogs, and monitoring history.
Monthly messages: Only messages that pass DMARC authentication count towards your plan limit. Spoofed or unauthorised messages that fail DMARC are not counted, so you are never penalised for being targeted. If you exceed your plan limit, reports continue to be processed but you will be asked to upgrade. We will never silently drop your data.
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: Prices shown exclude UK VAT, which will be added at checkout where applicable.
*MSP domain slots: MSP includes 100 domain slots. Need more? Additional slots are available in buckets of 50 for £39.99/month each. 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 organisations with custom domain counts, high email volumes, or specific compliance requirements. Enterprise includes unlimited data retention and a dedicated account manager. Contact us for a tailored quote.
