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, BIMI & encryption 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.
Reads the authentication reports sent by
No jargon. Here's your problem, how we solve it and exactly what we can - and can't - see.
Two things quietly do damage: real, legitimate emails can land in spam and anyone can send fake invoices or phishing under your company's name. Most businesses don't notice until a customer does.
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 in plain words exactly what to fix. Nothing to install, no IT team needed.
No - we can't. Not the content, the subject or who you write to. Nothing. Your real messages never pass through us. We only receive the aggregate security reports that Gmail, Outlook and Yahoo already generate - statistics, not messages.
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.
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.
No new software to install. No IT team required. You add one record and we do the rest.
Your domain settings have a list of records - the same place your website address and email are already set up. You're adding one more line to that list. It has three parts and here's what each one means.
What kind of record it is. TXT simply means "a line of text". Your DNS provider will show a dropdown - you pick TXT.
What the record is called. Mail providers know to look for this exact name when they receive a message claiming to be from you. The underscore is part of it.
The instruction itself. It's three settings separated by semicolons - broken down below. Your reporting address is unique to your domain; we generate the exact record for you when you add it.
v=DMARC1
"This is a DMARC record." Every one starts this way, so receiving servers know how to read the rest.
p=none
The policy - what should happen to fake mail. none means "don't block anything yet, just report". We start here deliberately: it's watch-only and cannot affect your real email. Once we can see every genuine sender, we move you to quarantine (fakes go to spam) and then reject (fakes are refused).
rua=mailto:…
Where the reports go. This is our address. Gmail, Outlook and Yahoo send a daily summary of everyone who emailed as your domain - we collect and translate them for you.
Adding this record doesn't reroute your mail and nobody gains access to your messages. It only publishes a public instruction and a reporting address - your email keeps working exactly as it does today.
We handle the technical part so you get the business result: mail that lands and a name nobody can misuse.
The same invoice, before and after your domain is authenticated. Nothing about the message changes - only whether Gmail trusts it.
Criminals send fake invoices "from" your company because, without DMARC, nothing stops them. We shut that door - carefully, so your own mail is never caught in it.
This is what an impersonation attempt looks like in your reports.
No dashboard to check. A short email when something changes - and you decide what qualifies.
Google, Yahoo and Microsoft now require authentication. You're on the right side of all three - without reading a spec.
The rest of your online presence breaks quietly too. Same dashboard, same alerts, nothing extra to buy.
Once a day we open a real TLS connection to your domain and read the certificate a visitor's browser would be handed. We store its expiry date and count down.
Most certificates renew automatically - until the renewal quietly fails. This is the check that notices.
Nothing. It starts on the domain you already added for DMARC. There is a per-domain switch in the dashboard if you ever want it off.
Why it matters: an expired certificate does not degrade quietly. Every browser replaces your site with a full-page security warning, and most people never click through it.
Once a day we ask the registry itself for your domain's expiry date over RDAP - the official replacement for WHOIS. That is the registry's own record, not your registrar's reminder email.
A few country domains do not publish an expiry date at all. When that happens we say so plainly rather than inventing a date.
Nothing. The domain you added is the domain we track.
Why it matters: renewal notices go to whoever registered the domain, often years ago and often to an address nobody reads any more. A domain that lapses takes your email and your website with it, and someone else can register it the moment it drops.
Every 30 minutes we make a real HTTPS request to your domain and look at what comes back. Anything that answers normally counts as up. A server error, a refused connection or a timeout counts as down.
One failed request is never an outage. Anything that fails is checked again a minute later, and only the second failure emails you - so a dropped packet or a one-off 502 doesn't wake you up. You get one email when the site goes down and one when it comes back, however long it lasts.
Nothing. Same domain, same dashboard, same alert recipients.
Why it matters: most small sites go down without anyone noticing until a customer mentions it. The point is that you hear it from us, not from them.
Once a day we take a snapshot of five records on your domain and compare it with yesterday's. The first run is only a baseline - no alert. After that, any difference emails you once, with the old value and the new one side by side.
Nothing. We read public DNS, so there is no access to grant and nothing to install.
If it was you or your IT provider, the email is a two-second confirmation. If it was not, it is the earliest warning you will get.
Why it matters: a domain hijack starts with a DNS change. Move the MX records and every email to your company goes somewhere else, with nothing broken on screen to tell you.
You don't need to live in it. It's there for the moment you want proof that everything is protected and working.
