The problem

Anyone can send email using your domain name

Without DMARC, nobody checks whether an email claiming to be from your organisation really is. That leaves room for phishing, invoice fraud and damage to your reputation, often without you noticing.

Spoofing and phishing

Fraudsters send invoices or links in your organisation's name. Customers and staff fall for it, and you are left with the reputational damage or the financial loss.

Poor deliverability

Without correct SPF, DKIM and DMARC, your own newsletters and invoices end up in the Gmail and Outlook spam folder sooner.

No view of the risk

DMARC reports are raw XML files. Without tooling you never know who is sending through your domain, until it is too late.

How it works

From DNS record to a clear dashboard, in three steps

Connect your domain

Add your domain and publish the DMARC record you get from us straight away. We show you exactly what goes where, with a ready-made value.

DuzMarc collects the reports

Mailbox providers like Google and Microsoft send DMARC reports every day. We collect them, decode them and give them structure, automatically.

You see at a glance what is going on

A clear dashboard shows who is sending on behalf of your domain, what passes and what fails, and whether anyone is abusing your name.

What you get

One overview for engineering, security and management

Enough depth for the IT administrator, enough clarity for the board.

Live dashboard

An overview of all your senders, volumes and authentication status, by domain and by period.

Geography (threat map)

See at a glance which countries are sending mail on behalf of your domain.

Senders & email vendors

Known services such as your CRM or newsletter tool are recognised automatically, so you can mark what is trusted.

Sender IP check

For an unknown sender you immediately see the ASN, organisation name and IP details, so you know whether action is needed.

Alerts

An automatic notification when a new sender appears, volumes look suspicious or reporting suddenly drops.

Abuse case file

Build a case file of abused sender IPs, complete with abuse contact details, ready to report.

Team & permissions

Invite colleagues with the role that fits: administrator or member, with two-step verification for everyone.

Domains & subdomains

Watch not only your main domain but every subdomain separately, each with its own policy.

Audit log

Every change made by a team member is recorded, so you can always trace who did what.

Comfortable for every team

Just as sharp in the dark

Whether you are checking the geographic map late in the evening or going through reports during the day: DuzMarc adapts, without giving up readability or contrast.
