What you agreed to, and what it says now.
Wisselpost keeps the proof and tells you what changed. In your insurance, subscriptions, energy and telecom contracts. Quietly, in the background.
Wisselpost is in development; the beta starts soon. No form: just send us an email.

Forward, keep, follow.
You don't have to organise anything or give access to your mailbox. You forward what's about your contracts; we do the rest.
You forward
You get your own forwarding address, for example
name.zonnige-walvis-27@wisselpost.nlSend policies, bills and contract emails there: by hand, or with a forwarding rule in your email.We keep the proof
We pick out the relevant documents and keep the originals encrypted, on a timeline per contract. We don't keep newsletters, promotions or other mail.
We tell you what changed
When a new policy, bill or price letter arrives, we set it next to the previous one. You only hear from us when something material changes. With the proof attached.
Every change points back to the document

Your recurring costs, and what you agreed about them.
We focus on contracts that keep sending you paperwork, so there is always an earlier version to check against.
Insurance
Premium, excess, cover, and what is or isn't in the policy any more.
Subscriptions
Monthly or yearly price, discounts and when they end, auto-renewal.
Energy and water
Rates, fixed charges, contract length and notice period.
Internet and phone
Monthly price, bundles and speeds, contract length and price changes.
Purchases and warranties
We keep the receipt and the warranty period, so you can find them when you need them.
What we ignore
Invoice numbers, creation dates, page numbers, a new layout and small wording changes that don't change your terms.
Never more certain than the document.
We report; you judge. An increase and a decrease look the same. If we can't find something, we write no longer found, not ‘removed’. And if we're unsure, it says: Possibly changed — please check the document.

We keep the proof, and as little else as possible.
You're sending us personal paperwork. We handle it sparingly, and we say exactly how.
Discard by default
We don't keep what isn't about your contracts: newsletters, promotions, personal mail and old messages below a forwarded email. An incoming email is held, encrypted, for at most 7 days so you can undo a mistake. Then it's gone.
Encrypted evidence
Original documents are stored encrypted, with a separate key per account, in the EU. If you delete your account, we destroy that key and the evidence becomes unreadable for good.
No selling of data
We don't sell your data, don't use it for advertising, and no AI models are trained on it. You pay for Wisselpost; you are not the product.
You decide
We don't cancel anything, negotiate or call anyone. What you do with a change is up to you.
No access to your mailbox
You only forward what you choose. We never ask for access to your whole inbox.
Your proof stays yours
You can export everything and delete your account at any time. If your subscription ends, you can still view and take your evidence with you.
What data we use, and who helps us process it, is in our privacy policy.
One yearly price, per email address you forward from.
You pay by the number of email addresses you forward from. Everything else is the same.

All prices are launch prices and include VAT. Wisselpost is free during the beta. Beta users get a founding-member price at launch.
What counts as an ‘email address’?
A mailbox you forward from to Wisselpost, for example your own Gmail and your partner's address. You confirm each address once. Your Wisselpost forwarding address doesn't count, and it doesn't matter how much you forward.
Zakelijk (business)
For freelancers and small businesses. Coming later.
If your subscription ends, we don't hold your evidence hostage: you can still view and export everything.
Frequently asked questions
Do I have to give Wisselpost access to my mailbox?
No. You forward what you choose, by hand or with a forwarding rule for, say, your energy supplier or insurer. Wisselpost can't look into your mailbox.
What happens to mail that doesn't matter?
We discard it. For 7 days the app shows what we discarded and why. If it was important after all, you restore it with one tap. After that the email is gone; we only keep a content-free marker to recognise duplicates.
Will Wisselpost cancel my contract if it gets more expensive?
No. We don't cancel anything, negotiate or contact providers. We show what changed, with the proof. What you do about it is up to you.
How certain is a detected change?
Every value is linked to the passage in the document it came from. Changes are determined by fixed rules, not by an AI model's opinion. If we're not sure, we write ‘Possibly changed — please check the document’ and don't send a notification.
Will I get lots of notifications?
No. You only hear from us when something material changes, or when a deadline is near, such as a discount or notice period ending. Not for every email that comes in.
Which providers does it work with?
With the documents you receive by email, from any provider: PDFs, emails and most attachments. We're starting with Dutch providers and documents.
Where is my data stored?
Your documents are stored encrypted in the EU. Some processing, such as reading documents, uses companies that may operate outside the EU. Which ones, and what they get to see, is in our privacy policy.
Can I leave and take my data with me?
Yes. You can export everything, including the original documents, and delete your account at any time.
