When someone asks me about their email authentication setup, I want to start with what is actually published.

Documentation may be outdated. A previous provider may still be part of the configuration. A new service may have been added without the rest of the team knowing. Looking at the current records gives the conversation a concrete starting point.

That is where the DMARCsimple DNS Record Checker comes in.

Give the review a starting point

The checker provides a way to inspect SPF, DKIM, and DMARC records for a domain. Open the tool, enter your domain, and review the available results.

Keep a note of what you find and when you checked it. That makes it easier to discuss the current setup with the person who manages your DNS or email service.

The goal of this first pass is to identify questions worth investigating, rather than immediately editing records.

Bring your list of sending services

Your mailbox provider may be only one part of your business email setup.

Think about your website, newsletter platform, CRM, support desk, billing system, and any other service that sends messages using your domain. Write those down before planning changes.

That inventory provides context for the DNS review. A setting that looks unfamiliar may belong to a service someone else in the business depends on. Equally, a service on your list may need a closer look.

Keep a check in perspective

A record check is a snapshot of configuration. It is not proof that every message your business sends is authenticated correctly, and it does not guarantee inbox placement.

That distinction is why DMARCsimple also provides ongoing monitoring and reporting. Configuration and observed sending activity answer different questions; reviewing both gives your team a more useful picture.

If a result raises a question, investigate it with the responsible provider or administrator. Avoid making changes solely to improve a displayed score without understanding the services involved.

Use the result to plan the next conversation

A useful outcome might be a short list of things to confirm: who owns the DNS configuration, which platforms send email, and whether your team is reviewing reports.

You don't have to solve everything in one sitting. Establishing the current state is progress, especially when several people or providers share responsibility.

Try the free DMARCsimple DNS checker and use the results as the starting point for that review.
