Mailhardener vs PowerDMARC (2026): which should you pick?

Pick Mailhardener if

• Fits if you run up to 10 domains and want reports and hosted MTA-STS
• Works for a personal domain you only want to look at

Look elsewhere if

• Skip it if your domain is a company's, as the free plan is for personal or evaluation use
• Tight if you want more than 3 months of history, as 12 months needs Large at EUR 99 a month
• Watch out: prices are in euros and no dollar price was readable
• Watch out: the page does not make clear which tiers have API access and SSO

Pick PowerDMARC if

• Fits if you're an MSP managing DMARC for many client domains
• Works for security teams that want DMARC data in Microsoft Sentinel, Splunk or Elastic

Look elsewhere if

• Not for you if you want a price before talking to anyone, as none is on record
• Watch out: no free plan or trial is on record; older help articles mention a free trial whose terms couldn't be read
• Skip it if you need list cleaning or warm-up, which it doesn't do
• Tight if you run one small domain, as much of the setup is aimed at MSPs running many clients

Mailhardener

• Prices are shown in euros; the page has a currency selector, but a dollar price was not readable from the server.
• The free plan is for personal or evaluation use only, not commercial domains.
• The comparison table lists API access, SSO and periodic reports, but which tiers include them could not be read from the page text.

PowerDMARC

• The website turned our reader away with a bot check and the help center lists no prices, so what it costs could not be confirmed.
• Older help articles mention a free DMARC trial; its current terms could not be read.
• PowerDMARC does not verify lists or warm up inboxes.

Mailhardener

DMARC reporting

Aggregate (rua) and failure (ruf) reports show every sender using the domain, with a plain-English breakdown. The vendor says its algorithm separates forwarding services from malicious senders.

SMTP TLS reporting

TLS failures reported by sending servers are aggregated and analyzed, with warnings by email.

Hosted MTA-STS and BIMI assets

Mailhardener serves the MTA-STS policy and BIMI assets so a domain can adopt them without running a web server.

DNS change monitoring

Email-related DNS records are monitored, and a notification explains what a change does to protection.

Domain inspector

Shows how SPF, DKIM, DMARC and related records are configured and flags common mistakes.

Multi-user access and auditors

Paid tiers support role- and domain-based access control, several organizations per login and read-only auditor access.

PowerDMARC

DMARC reports

Aggregate and forensic report views, spoofing IP reports, SPF analytics, subdomain discovery and scheduled PDF reports.

Hosted records

Hosted DMARC, SPF (PowerSPF), DKIM, BIMI, MTA-STS and TLS-RPT let you change records in PowerDMARC instead of at the DNS host.

PowerAlerts and threat intelligence

Alert rules for authentication, DNS and TLS-RPT thresholds, and threat intelligence on IPs sending as your domains.

Inbox Placement Analyzer

A self-service test of where your emails land, alongside a Google Postmaster Tools integration.

MSP tools
