DMARC
DMARC is a rule that tells email servers how to handle emails from your domain.
DMARC stands for Domain-based Message Authentication, Reporting and Conformance. It is a set of instructions that tells email servers what to do with emails that claim to come from your domain. When someone tries to send an email pretending to be from your company, DMARC helps stop that email before it reaches your inbox.
Why it matters is because fake emails can trick people into giving away passwords or money. These emails often look real and can be hard to spot. By using DMARC, you make it harder for scammers to impersonate your company.
An everyday example is when a scammer tries to send an email that looks like it's from your company's support team. With DMARC in place, the email is either blocked or sent to spam, protecting your customers and your reputation.
What to do is set up DMARC for your email domain. This involves creating a special record in your domain's DNS settings. You can use free tools to help you set this up. Once set, you'll also get reports about how your emails are being handled, which helps you spot problems early.
