DMARC reporting

The DMARC reporting feature gives insight into all emails being sent using your domain name in the sender address.

This includes the email sent from your email server, and third parties such as your marketing platform, billing system and reporting tools, but also unauthorized senders such as spammers or fraudsters.

The unique Mailhardener self-learning algorithm is the first to accurately distinguish forwarding email services from malicious senders, which greatly reduces false positives.

SMTP TLS reporting

Mailhardener is one of the first to offer fully featured SMTP TLS reporting using the SMTP TLS reporting standard.

This will give insight into TLS failures encountered by SMTP services attempting to deliver email to your domain.

Mailhardener will aggregate, enrich and analyze SMTP TLS reports and automatically warn you about any problems that are reported by email senders.

MTA-STS policy hosting

MTA-STS is an email security standard that mitigates DNS based attacks where attackers could read or manipulate email addressed to your domain.

Deploying MTA-STS can be challenging for organizations due to its strict implementation requirements. To overcome this, Mailhardener offers hosted MTA-STS services that allows any domain to adopt MTA-STS in less than 5 minutes, with zero maintenance.

BIMI asset hosting

BIMI is an upcoming email standard that allows organizations to improve their branding in email communication, which improves recognizability. It is like verified accounts, but for email.

Deploying BIMI can be challenging for organizations due to its strict implementation requirements. To overcome this, Mailhardener offers BIMI asset hosting services that allows any domain to adopt BIMI in less than 5 minutes, with zero maintenance.

DNS change monitoring

Reports show that many high impact fraud cases were possible due to unauthorized changes made to domain settings (DNS).

Mailhardener will monitor all email related DNS features, and notify you when a change is detected.

The notification will also give you a breakdown of what difference the change will make to your email protection.

Report breakdown

There is more than one way to prevent unauthorized email, and many reasons why a receiving system might decide to accept or reject your email.

The report analysis tool gives you a breakdown in easy to understand English of how the receivers processed the email and why it did or did not accept the email.

Domain inspector

Most of the email fraud prevention is set up in your domain settings, so naturally this is an important part to get right.

There are many settings though, and even more subtle ways in which configuration mistakes can be made.

The Mailhardener domain inspector will show you exactly how your domain is set up, with easy to read English breakdown.

It also detects commonly made mistakes, so you don't accidentally make them.
