Every day, a significant share of your business emails silently disappear into spam folders — never reaching clients, prospects, or partners. That's invoices, quotes, and relationship-building emails your customers never see.
The Invisible Problem
Your emails look fine to you — but spam filters check hidden technical settings that prove you are who you say you are. Without these, Gmail, Outlook, and Yahoo treat your messages as suspicious.
The Cost to Your Business
Businesses lose an estimated £1,840/month in pipeline from undelivered emails — an illustrative UK SME estimate based on publicly reported email-delivery loss studies (2025). Actual losses vary by business, sector and email volume. Missed invoices. Lost quotes. Clients who never got your reply and went to a competitor.
What Hackers Exploit
Without proper authentication, criminals can send emails pretending to be your business — fake invoices to your clients, phishing emails to your staff. Your brand reputation on the line.
* Illustrative estimate — not a forecast. Actual losses vary by business size, sector and email volume.
The good news? Our free 30-second scan above tells you exactly where the gaps are — and what to do about it.
The 3 Security Checks Every Business Email Needs
Our scan tests three hidden settings that prove your emails are legitimate. Think of them as your email's passport, signature, and security policy.
Your Sender Passport (SPF)
Tells the world which servers are allowed to send email from your domain. Like an approved staff list at a bank — if someone isn't on it, they can't access your account.
Your Digital Signature (DKIM)
Adds an invisible digital wax seal to every email you send. When the recipient's email provider sees an unbroken seal, it knows the message is genuine and hasn't been tampered with.
Your Spam Rulebook (DMARC)
Tells Gmail, Outlook, and Yahoo what to do with suspicious emails claiming to be from you — ignore them, quarantine them, or block them entirely. Your email bouncer.
