Key features
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.
Suped
- DMARC report parsing
- Raw XML aggregate reports are turned into a view of every sending source, with alerts when new senders appear or authentication rates drop.
- Hosted DMARC, SPF, DKIM and MTA-STS
- Records are managed from a dashboard instead of edited in DNS by hand. SPF flattening keeps a record under the 10-lookup limit.
- BIMI setup and hosting
- Suped prepares and hosts a BIMI logo and record on paid plans. Trademark registration and certificate services are quoted separately.
- Blocklist and reputation monitoring
- Sending IPs are checked against major blocklists, with an alert when one is listed. This is a paid-plan feature.
- Lookalike domain monitoring
- Listed for the Enterprise and MSP plans only.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
