How to protect your domain with DMARC using GlockApps

How to Use DMARC Analyzer

Email phishing and spoofing increased by 220% in 2021. Protect your brand from cyber attacks that could ruin your reputation and cost you thousands.

DMARC was developed to assure SPF and DKIM alignment. It helps secure legitimate email senders and their recipients against email spoofing attacks. In order to protect your brand reputation and recipients, we recommend using the GlockApps DMARC Analyzer.

Follow these simple steps to start monitoring DMARC with GlockApps and get valuable data about your email traffic in a comprehensive and user-friendly way.

How to Set Up DMARC Analyzer

After you activate DMARC Analytics in your account, you have to create a DMARC record for your domain.

Add Your Domain

To do this, go to Add Domain section under the DMARC Analytics tab, enter your domain name, and click Next.

However, if you already have a DMARC record, we recommend you use the DMARC record GlockApps generates for you. This will help DMARC Analytics collect data and generate reports.

DMARC monitor

By default, GlockApps displays the current DMARC Policy for your domain. 

Select Your DMARC Policy

In the Configure DMARC tab, you can set up different policies and settings for your DMARC record.

DMARC tester

If you haven’t monitored DMARC before, we recommend you keep the None policy (which is a monitoring mode.) This option allows you to get a deep insight into your domain’s sending sources and email authentication before enforcing the DMARC Quarantine or Reject policy.

Additionally, you can apply different policies for subdomains.

Your main domain’s policy will automatically be applied to your subdomains, unless you choose a different DMARC Policy for each.

    • Relaxed:  The “Header From” domain & DKIM do not need to match.
  • SPF Alignment
    • Strict: The  “Return Path” Domain & “From” field domain must match. 
    • Relaxed:The  “Return Path” Domain & “From” field do not need to match.
