Email Authentication
Email is how your business gets paid, signs contracts, and runs day to day. By default, your domain has no lock on the front door — anyone in the world can send email that looks exactly like it came from you, and the recipient has no reliable way to tell the difference.
What's at stake
Your customers get scammed in your name
Without authentication, fraudsters can send invoices that appear to come from your business. Your customer pays them. You find out weeks later when accounts receivable asks why the payment never arrived.
Your legitimate email lands in spam
Gmail, Outlook, and Apple Mail now treat unauthenticated email as suspicious by default. The quote you sent yesterday might be sitting in a spam folder right now — and you have no way to know.
Insurers and clients are starting to ask
Email authentication used to be obscure. It isn't anymore. Cyber insurance applications list it as a baseline control, and larger clients increasingly include it in vendor due diligence questionnaires.
Your brand wears the damage
When someone gets phished by an email that appears to come from your domain, they don't remember it was a spoof. They remember it came from you.
What this module gives you
The Email Authentication module walks you through locking down your email domain at the DNS level — the same configuration that the major banks, government departments, and well-protected businesses use. By the end, you'll have:
A clear picture of who's currently sending email as your business.
Most owners are surprised by what they find here.
The right DNS configuration in place, in the right order.
Done wrong, this can block your own legitimate email. The module walks you through the sequence that keeps your inbox flowing.
Daily visibility into who's trying to use your domain.
Reports arrive automatically and tell you exactly who is sending mail in your name — legitimate and otherwise.
A clear indicator that you've reached “fully protected” status.
No guessing whether you're done. You'll know.
Evidence you can show insurers, clients, and auditors.
When the question comes up — and it will — you have the answer in writing.
Why this matters right now
Google and Yahoo now require bulk senders to authenticate. Microsoft and Apple are tightening their filters. The ACSC has flagged Business Email Compromise as one of the most-reported cybercrime types from Australian small and medium businesses. The window where “we'll get to it later” was an acceptable answer is closing.
Lock the front door of your business email.
