You never miss a single letter. Never.

When you set up a company in the UK or Delaware, you receive official correspondence: HMRC notices, Companies House forms, IRS communications, bank statements, legal requests. The Mailbox takes care of it all.

Instant notification

As soon as a letter arrives at your address, we open it, scan it, and notify you by email + WhatsApp + dashboard in under 15 minutes.

Your advisor reads it first

If the letter is urgent or needs action (HMRC, IRS, Companies House), your personal advisor reviews it and explains what to do in Spanish, before you even open it.

Searchable archive

Every letter is OCR-scanned. Search by text, date, sender, or tag and find it in seconds. Your tax records, ready for audits or inspections.

All the official mail for your company.

The intelligence of Aiden,
working with you.

Deployed across all of Aiden Emails, website copy, replies to customers. Lunnar learns how you write and takes over — it almost feels like magic.
Your greatest ally An unpaid invoice, a domain up for renewal, a website running slow. It tells you beforehand, not once it's already a problem.
Sums up what you don't have time for. Forty unread emails become five lines with what you really need to look at today.
Helping you 24 hours a day Even at 3 in the morning, our AI Lunnar helps you by connecting to your account and sorting out your issues on its own
Builds your website with you watching.
Builds your website with you watching. You tell it what you do and it puts together a first version. From there you change it by talking, not by touching code.
And it keeps nothing of yours. What you tell it is used to help you. It doesn't train anyone else's models and isn't sold to anyone.

What you might be wondering.

Is the Mailbox included in all plans?
Yes. The Mailbox is included at no extra cost in all plans (Standard and PRO, UK and Delaware). It's part of your registered office address.
What if I need the physical original?
On request, we'll send the original to the address you provide. We keep originals for 6 months by default. International forwarding is billed at the actual shipping cost (~€10-25 depending on destination).
How quickly do you receive and notify?
Mail is processed in 4-hour windows during business hours (UK / Spain). The average time from receipt to notification is 15 minutes. Letters marked urgent (HMRC, IRS) are processed in under 1 hour.
Who opens the letters?
Aiden staff under signed confidentiality agreements. Letters that require action are reviewed by your assigned personal advisor, not by third parties. If you'd rather we didn't open letters (envelope scan only), you can enable that in settings.
What happens if an urgent legal notice arrives?
We activate a priority protocol: we call you by phone in addition to the digital notifications, and if the matter requires a lawyer, we connect you directly with one from our partner network (UK Solicitor or US Counsel depending on the country).
Do I have access to the full history?
Yes. As long as you're a customer, your digital archive is unlimited. Search by OCR text, filter by sender, date, type. If you cancel, we'll give you a ZIP export with your full history.
