MailSurety SPF · DKIM · DMARC · monitored
Email security, done for you 🇬🇧 🇮🇪 🇨🇦

Your email should reach the inbox — and nobody should fake it.

Missing or broken email authentication sends your messages to spam and lets anyone send fake invoices in your company's name. We set it up, watch it every day, and tell you what to fix — in plain English.

Free, instant, no signup. We score your live SPF, DMARC & mail setup — nothing is stored.

We can never read your email. Not the content, the subject, or who you write to — your messages never pass through us. We only read the security summary reports.

The 3 things everyone asks first

No jargon. Here's your problem, how we solve it, and exactly what we can — and can't — see.

1

What's the problem?

Two things quietly cost you: your real emails can slip into spam, and anyone can send fake invoices or phishing in your company's name. Most businesses don't notice until a customer does.

  • Real emails landing in the spam folder
  • Fake invoices sent in your name
  • You find out only when a customer does
2

How do you fix it?

You add one line to your domain — or we do it with you on a short call. Then we watch your email around the clock and tell you exactly what to fix, in plain words. Nothing to install, no IT team needed.

  • One line added — or we do it with you
  • Watched around the clock, automatically
  • Plain-English fixes — no IT team needed
Your mail flow, live

See where your email goes — and where fakes get stopped

Every source that sends "as you", the authentication check at Gmail, Outlook & Yahoo, and exactly where each message lands. Impersonators are spotted and blocked in real time.

Why this matters now

Email deliverability stopped being optional

The big mailbox providers changed the rules. If your domain isn't protected, your mail quietly slides into spam — and your name is up for grabs.

Feb 2024
Google & Yahoo began requiring email authentication from senders. Microsoft followed. No DMARC increasingly means the spam folder.
1 record
One TXT record on your domain turns on protection and starts the daily reports. That's the entire setup on your side.
24 / 7
Every message sent in your name is checked around the clock — new apps, new staff, and spoofing attempts included.
How it works

Protection in three simple steps

No new software to install. No IT team required. You add one record and we do the rest.

You add one DNS record

We give you a single line to paste into your domain settings. Takes two minutes — or we do it with you on a call.

We read the daily reports

Gmail, Outlook and Yahoo send reports on who's emailing as you. We collect and decode them automatically.

You get a clear action

"This is fine. Fix this. Block that." We tighten your protection safely until fakes are rejected and real mail flies.

What you get

Everything working, nothing to understand

We handle the technical part so you get the business result: mail that lands and a name nobody can misuse.

Inbox deliverability

Get your legitimate email out of spam and in front of the customers, invoices and quotes that pay you.

Anti-spoofing protection

Stop criminals sending fake invoices and phishing "from" your company. Your brand can't be impersonated.

Plain-English reports

No jargon, no dashboards you'll never open. Just "here's what's happening and here's what to do."

Safe path to full lock-down

We move you to a "reject all fakes" policy gradually — so spoofers get blocked and your real mail never does.

Always-on monitoring

Add a new CRM, newsletter tool or team member? We catch it before it breaks your deliverability.

Meets the 2024 rules

Stay compliant with Google, Yahoo and Microsoft sender requirements — without reading a single spec.

Your dashboard

See exactly who's sending as you

When you become a client you get a private dashboard — but you don't need to live in it. It's there when you want proof that everything's protected and working.

  • Every legitimate sender, verified and labelled
  • Spoofing attempts spotted and blocked
  • Your live deliverability score, trending up
