Silverpost
Your mum or dad sends any suspicious text, email or letter. Silverpost answers in plain English: does it look like a scam, and why. If it does, the family knows at once.
The iPhone app is with Apple for review, and founding families can use it now through TestFlight. Android follows.
The problem
Every Tuesday
Two are junk, one is a pension statement, and one has a date on it that matters. He will get to them at the weekend. He has been getting to them at the weekend since March, and the inbox on the tablet is worse.
Thursday, 6.04pm
A text says a parcel is held and a small fee is due. It arrives on the evening she really is waiting for a delivery, it looks exactly like the real ones, and it wants her card details. She has about thirty seconds to decide, on her own, with nobody to ask.
Sunday, 7.12pm
Hi dad, I have dropped my phone down the loo, this is my new number. It sounds like your son. It uses the name he calls you. By the time the rest of the family hears about it, the money has gone, and your dad is too embarrassed to say how much.
Criminals stole £1.28 billion through payment fraud in the UK in 2025, and eight people were defrauded every minute. The ones who lose the most are usually the ones who were certain they would never fall for it. UK Finance, Annual Fraud Report 2026.
How it works
Step one
A text, a WhatsApp, an email, or a picture of a letter. They send it the way they would send a photo of the dog. There is nothing to log into and no form to fill in first.
Step two
What it is, who it is really from, whether there is a deadline, and what to do next. Written in plain words, with no jargon, and never a lecture.
Step three
Anything dangerous appears in your family feed the moment it happens. You never have to ring and ask whether anything has come. So the whole family gets a second look, the moment it matters.
See it for yourself
An illustration of how Silverpost answers. These are example messages.
This is not your son or daughter. It is the "Hi Mum" scam.
Do not reply, and do not send any money. Ring them on the number you already have for them, the one saved in your phone. They will not mind being checked.
Sent to the family feed straight away
Silverpost is a second pair of eyes for the family, not a guarantee. When it is not sure, it says so.
Nothing to install
No download, no account to make, no new app to learn. Your mum saves one number, the way she saved yours. Then she sends it a photograph of a letter, or forwards a text she is unsure about, and a plain answer comes back in about a minute. Setting her up is one tap on a link you send her.
The door
A photograph of a letter, or a text forwarded straight on. It answers in the same conversation, so there is nothing to go back to and nothing to remember.
On the phone
An email, a text, a screenshot. Whatever is on the screen goes to Silverpost with the share button, without leaving the app they are already in.
In the app
For the person who can tap but cannot attach. The app becomes one large button, and the answer comes back in big print and read out loud.
When the phone rings
Nobody can tell a real call from a good scam while it is happening, and asking an eighty year old to try is how people lose everything. So the rule does not ask them to judge it.
The drill
A phone call about money, from anyone. Hang up. Then send the word CALL.
The hang up script comes straight back, with no waiting, and the rest of the family is told at the same moment, so somebody can ring and check on them.
Hanging up on a real bank costs nothing. They will ring back, or you can ring them on the number on the back of your card. No genuine caller has ever minded.
It is a drill, not a test. Nobody is asked to spot anything, and nobody is made to feel foolish for hanging up on their own daughter.
What it catches
Evri, Royal Mail, DPD. A parcel held, a small fee, and a link that is not theirs.
A WhatsApp or text from your son or daughter, from a number that is not theirs.
Penalty notices, parking charges and HMRC refunds, all invented to make somebody panic.
The call or text saying the account is at risk, asking them to move money to be safe.
Insurance and energy letters where the price has quietly risen by a hundred pounds.
The real letters, with real dates, which matter every bit as much as the fake ones.
The network
When one family checks a scam message, Silverpost keeps a fingerprint of it. Not the message, the shape of it. When the same campaign reaches another family, their answer says so: this one has been seen before. No family's messages are ever shared with another. Only the fact that a pattern has been seen travels.
Set a word only your family knows. When a message claims to be your son from a new number, the answer reminds them to ask for it.
When something pretends to be a bank, HMRC or a delivery firm, the answer carries that organisation's genuine number, checked against their own site.
Forwarding the text to 7726 and reporting to Action Fraud come as part of the answer, rather than as homework nobody does.
The promise
What your family sends it stays your family’s business.
Plainly, so you can weigh it up: the reading is done by Anthropic’s Claude, on servers in the United States, under a written agreement with the safeguards UK law requires for sending data abroad. A fully private mode, where letters never leave Silverpost’s own machines, is on our roadmap. We will tell you the day it arrives, and not a day before. It is all set out in the privacy policy.
It is never sold and never used to train AI. The letter is read under contract by our AI provider, we keep the check so the family can see it, and server logs are deleted after 30 days. That's it.
Joining
The family plan
£79 a year
or £7.99 a month, cancelled whenever you like
You can try it before you pay. The WhatsApp number is free for the first month from the day you first message it, with nothing to install and no card. Save 0330 223 8242 as Silverpost and send it something you are not sure about. After the month, it becomes the family plan, and the family is told the moment anything dangerous arrives.
Founding families
The first fifty families join at half price, £39.50 a year, and keep that price for as long as they stay. In return we ask for honest feedback, including the parts we get wrong.
Card payment through Square. Within a few minutes an email arrives with everything you need, including the WhatsApp number to save on your mum or dad’s phone. If it does not appear, look in spam once, then write to hello@silverpost.co.uk.
Not on the stores yet. Founding families are told the day they are, before anyone else.
