Control your senders

For most domains, email is sent by various services. You may use a marketing platform to send your newsletter, a payment provider to send receipts and so on.

It's useful that third parties can send email on behalf of your domain, but it also poses a risk that fraudulent actors do that too.

Email has security standards to control which senders are allowed to send email for your domain. Receivers use these policies to determine if a sender is to be trusted.

Mailhardener helps you to manage these policies, whilst monitoring all email traffic that use your domain name. This helps you to block fraudulent activity and also reduce delivery problems of legitimate email.

Relevant security standards: SPF, DKIM and DMARC.

Secure transport

Email travels through many systems across the globe, all of which can intercept your email as it passes through.

Luckily, email transport protocols all have support for encryption to prevent interception. Email messages itself can be digitally signed to prove authenticity.

Mailhardener comes with MTA-STS policy hosting, and BIMI asset hosting included, so adoption is a breeze.

Improve deliverability

Spam detection algorithms use the security features as trust indicators for email and domains. The more security checks an email passes, the more the sender can be trusted.

By using the email security features, not only do you improve security for yourself, you'll also reduce the chance of your email being falsely flagged as spam. It's like SEO, but for email.

Mailhardener shows you the security results of the emails sent from your domain, so you can improve deliverability of your email.
