Email security for your business
Stop criminals sending email as your domain — and keep your own email out of spam folders.
Your domain is a target.
Without SPF, DKIM, and DMARC, anyone on the internet can send email that looks like it came from your business — fake invoices to your customers, phishing to your staff. And it cuts both ways: Google and Yahoo now junk mail from unauthenticated domains, so a misconfigured domain means your own quotes and invoices quietly stop arriving.

Common questions
What are SPF, DKIM, and DMARC?
They're DNS records that prove email claiming to be from your domain really is. SPF lists who may send for you, DKIM digitally signs your mail, and DMARC tells receiving servers what to do when a message fails those checks — and sends you reports about it.
We're a small business — are we really a target?
Yes. Invoice fraud and business email compromise overwhelmingly target small businesses, precisely because their domains are less likely to be protected. An unprotected domain lets criminals send convincing fake invoices to your customers as you.
Will this stop phishing?
It stops criminals impersonating your domain, and inbound filtering catches much of the phishing aimed at your team. Combined with multi-factor authentication, it removes the most common ways small businesses get compromised.
Will it improve email deliverability?
Yes. Google and Yahoo now require sender authentication, and mail from misconfigured domains increasingly lands in spam. Correctly authenticated email is far more likely to reach the inbox — including your invoices and quotes.
Sorting out your email anyway?
Email security pairs naturally with a Microsoft 365 setup or a new website — one engagement, everything configured together.
