Full review
Mailhardener B.V. is registered at the Netherlands Chamber of Commerce (KVK) under number 92907814, with an office at Caballero Fabriek, unit 18, in The Hague. Its terms of service are governed exclusively by Dutch law, with disputes brought before the courts in the Netherlands.
The Mailhardener Suite reviews DMARC reports and SMTP TLS reports, inspects domain properties and manages the services that send mail for a domain. Mailhardener also offers email hardening consulting.
Which standards does Mailhardener cover?
Mailhardener lists DMARC aggregation for rua and ruf reports, SMTP TLS aggregation, hosted MTA-STS, BIMI asset hosting and DNS monitoring on its paid plans. DANE monitoring and periodic reports are in the comparison table.
Mailhardener states that users must change DNS records for each domain, as its documentation describes.
What are the Mailhardener plans?
Mailhardener is free for personal or evaluation use with one domain and one month of retention. Standard costs EUR 19 a month or EUR 199 a year for up to 10 domains with 3 months of retention.
Large costs EUR 99 a month or EUR 999 a year for up to 100 domains and 1 year of retention. Enterprise is quoted on request and lists a private instance option, eIDAS qualified signatures and DORA agreements.
Mailhardener as a European alternative to Valimail
Mailhardener gives a Dutch B.V. as the contracting party and lists a private instance, which Valimail's pages do not mention. Mailhardener is a hardening and monitoring suite and does not describe a managed enforcement service.
Known limits
Mailhardener does not state its hosting region on the pages we read, and the free plan is limited to evaluation and non-commercial domains. A business using Mailhardener on its own domain needs the Standard plan at EUR 19 a month. For an EU hosting statement, see dmarced or DMARCwise.
Who Mailhardener fits
Small businesses, MSPs and compliance-minded organisations that want a Dutch supplier with public prices and an optional private instance.
