Frequently Asked Questions

What exactly is DMARC and why is it so important now?

DMARC, which stands for Domain-based Message Authentication, Reporting, and Conformance, is like a security guard for your email. It works with other systems, SPF and DKIM, to make sure emails claiming to be from your domain are actually from you. In 2026, it's super important because email providers like Google and Yahoo are cracking down on unverified emails. If you don't have DMARC set up, your emails might not even reach people's inboxes, or worse, criminals could send fake emails pretending to be you.

Do I really need to set up DMARC if I only send a few emails?

Yes, even if you send just a few emails, setting up DMARC is a good idea. It's not just for big companies sending tons of emails. Criminals often target smaller businesses by faking their emails to trick customers. DMARC helps protect your brand and your customers, no matter your email volume. Think of it as locking your front door – you do it whether you live alone or with a big family.

Is it hard to set up DMARC?

Getting started with DMARC is easier than you might think. The first step is usually just adding a simple record to your domain's settings. Many tools can help you create this record. The real work comes later, when you need to check reports to make sure all your legitimate email sources are set up correctly. It’s a process, but many tools make it much simpler.

What's the difference between DMARC policies like 'none', 'quarantine', and 'reject'?

These policies tell email receivers what to do with emails that don't pass DMARC checks. 'None' means just report on it, don't do anything. 'Quarantine' means put it in the spam folder. 'Reject' means block it completely. You usually start with 'none' to see what's happening, then move to 'quarantine', and finally 'reject' for the best protection.

What are DMARC reports and why do I need a tool to read them?

When emails are sent claiming to be from your domain, email providers send you reports about them. These reports are usually in a computer-readable format called XML, which is really hard for humans to understand. DMARC reporting tools take these confusing reports and turn them into easy-to-read charts and summaries, showing you who is sending email as you and if they are passing or failing checks.

How do I choose the best DMARC reporting tool for me?

When picking a tool, think about what you need. Some tools are great for just checking if your DMARC record is set up right, while others offer ongoing monitoring and detailed analysis. Look for tools that clearly show you which services are sending emails for your domain, help you understand any problems, and offer a clear path to improving your email security. Many offer free trials or basic free versions to get you started.
