Email stamps
A stamp that proves this email is really from you
Before an invoice, a payment reminder or the exhibitor manual goes out, stamp it. Anyone who clicks the stamp sees what your real email looked like. If a scammer copies the stamp into a fake, we spot that it doesn’t belong.
The problem
A logo in an email proves nothing
Scammers copy your emails word for word. They change one thing, usually the bank details or a link, and send it to your exhibitors. To the person reading it, the fake looks exactly like the real one.
A badge that just says “verified” doesn’t help either, because it can be copied as easily as your logo. What people need is something that belongs to one email and can’t be moved to another.
How it works
4 simple steps
Make a stamp
One click from your dashboard. Give it a name like “Stand invoices, March”.
Paste it into your email
It’s a small badge that sits under your signature.
Send with us copied in
Add your private SummitShield address, and the stamp learns your real email.
Anyone can check
Clicking the stamp shows the original. A copied stamp is flagged.
One stamp, one email
Each stamp belongs to a single email. Once it has seen your real one, it shows who sent it, when, and where its links really go. Put it into a different email and it no longer matches, so anyone who clicks it is warned.
- Shows the real sender, date and links
- Works in Outlook, Gmail and every newsletter tool
- Set how long it lasts, and cancel it any time
Made for newsletters too
Sending to thousands of exhibitors through Mailchimp, HubSpot or another tool? Each copy’s stamp can name the person it was sent to. If a scammer lifts the stamp from their own copy, anyone clicking it can see it wasn’t meant for them, and you can see whose copy it came from.
- Each recipient’s copy is personal to them
- Spot which copy a scammer took it from
- Nothing extra for your readers to do

Why it matters
An exhibitor receives two invoices for the same stand, a day apart. One has a stamp. They click it and see the original from the organiser’s accounts team, sent the day before, with the correct bank account. The other has a copied stamp, which tells them straight away that it doesn’t match. They pay the right one.

Questions people ask
Do my recipients need an account?
No. They just click the stamp. It opens a simple page that anyone can read on any device.
Which emails should I stamp?
Anything that asks someone to pay, change details, log in or book something: invoices, balance reminders, hotel and travel information, the exhibitor manual and important deadlines.
Can someone copy my stamp?
They can copy the picture, but not what it belongs to. A copied stamp in a different email doesn’t match the original, and people who click it are told so.
Is there a quicker way to make a stamp?
Yes. The free Quick Stamp app puts the stamp maker on your desktop or phone, so you can stamp an email in two clicks without opening the portal.
Does it track who opens my email?
No. The stamp doesn’t record who opens your email. It only shows a page when someone chooses to click it.
