How to Setup DMARC: DMARC Defender Quick Start Guide

Welcome to dmarcdefender.io's DMARC quick start guide! In the guide we'll walk through the process of installing DMARC on a new domain using dmarcdefender.io.

First step is to create an account on DMARC Defender. You can sign up here:

After creating your account, you'll be redirected to the Setup Domain page. Type in the domain you want to protect with DMARC Defender.

After entering your domain, the wizard will generate a unique DMARC policy for your domain.

Next you'll need to update your domain's DNS records to include the DMARC policy. We'll be adding a TXT record to your DNS settings.

An example for AWS Route53 can be seen here, but your DNS provider's exact instructions may differ:

Once setup, click Verify in dmarcdefender.io's Domain Setup Panel to ensure everything is set up correctly.

A list of setup guides and videos can be found on our providers page.

DMARC Defender will now start receiving DMARC reports for your domain (it normally takes 24-48 hours to receive the first report). You can monitor these reports in the DMARC Reports section of the dashboard.

The reports help you to understand how your domain is being used and identify any unauthorized email sources. It's possible there are authorized senders for your domain that are missing DKIM/SPF records. DMARC Defender will highlight those services and assist you in adding the necessary records.

Once you feel comfortable with the reports and have ensured all legitimate email sources are properly authenticated, you can adjust your DMARC policy to a more restrictive setting (for example, quarantine or reject) to enhance your domain's email security. You can use the setup wizard to generate an updated policy.

All done! You have successfully set up DMARC Defender for your domain. Make sure all domains you own are protected by repeating these steps for each domain.
