Full email security for $29/month

2 domains, 1 user, 30 days data retention, 7 protocol monitoring (DMARC, SPF, DKIM, BIMI, MTA-STS, TLS-RPT, ARC), basic compliance scoring, email alerts, 2FA, and 5 AI assistant queries per day. No credit card required.

Pro is $29/month and includes your first 2 domains. After that you pay per domain: $15/domain/month for domains 3–10, dropping to $10/domain/month from domain 11 onward. No per-email-volume caps and no overage fees — we never charge you for how much mail you send.

No. We bill per organizational domain, so example.com and every subdomain under it — mail.example.com, eu.example.com, any number of them — are one domain on your plan. Only a separate registrable domain is a second one. Subdomain reports reach you because your own DMARC record asks for them, so charging for data you cannot decline would be indefensible.

The first 25 paying customers lock in founding rates for 24 months at 50% off the standard card: $14.50/month including 2 domains, then $7.50/domain/month (domains 3–10) and $5/domain/month (11+). Monthly or annual — annual is 2 months free. After the 24-month lock, founding members move to standard pricing with a permanent 15% alumni discount — forever, on any future plan.

You keep a permanent 15% discount off our standard rates — on every plan, every tier, forever. No re-negotiation, no surprise jumps. If the standard per-domain rate is $15/domain/month at that point, alumni pay roughly $12.75. You also keep your founding badge. The 24-month duration and alumni rate are stated at signup, so there are no surprises.

Hosted DNS ($12/domain/mo) is the one optional add-on: we host and manage your DMARC, SPF, DKIM, MTA-STS, BIMI, and TLS-RPT DNS records for you, including certificate issuance and renewal. Everything else — including PCI DSS and SOC 2 compliance reporting and auditor-ready PDF exports — is part of Pro at no extra cost. Enterprise plans include all add-ons.

Yes. Every new account starts with a free 30-day Pro trial automatically — no credit card required. After 30 days, you'll be moved to the Free plan with a clear summary of what changes.

Free includes 7 protocols: DMARC, SPF, DKIM, BIMI, MTA-STS, TLS-RPT, and ARC. Pro and Enterprise add DANE and ARF for the complete 9-protocol stack.

No — every price we quote is net. Prices exclude VAT and sales tax, which are calculated and added at checkout based on your billing location. Polar Software, Inc. is our merchant of record and shows the exact tax before you pay, then remits it to your tax authority. If your business has a tax registration, enter it at checkout: where your jurisdiction provides for it — the EU and UK reverse charge, for example — no tax is added at all. Polar shows the exact amount either way before you pay.

Yes. No cancellation fees, no contracts. Monthly plans cancel at the end of the billing period. Annual plans can be cancelled anytime — we'll refund the unused portion.

Our open-source parser (parse-dmarc on GitHub) is free to self-host. It covers basic DMARC report parsing with a minimal dashboard — but that’s where it stops. No named sender identification, no multi-protocol monitoring, no AI assistant, no alerting. DMARCguard Pro adds all of that, plus the compliance evidence your auditor asks for. You shouldn’t need to stitch together scripts and workarounds for email authentication — you should get actionable insights, not just raw data and XML.
