Mailroom automationTHE DAILY GRIND
You know the routine.
Open 50 envelopes. Read each letter to figure out who it's for. Walk to the scanner. Scan them one at a time. Save each PDF. Write an email. Attach the PDF. Send it. Repeat.
Miss one HMRC penalty notice buried in the pile and your client gets a fine. Scan a letter to the wrong client and you've got a data breach. It takes hours every week — and it's the task nobody wants to do.
HOW COMPLYPOST WORKS
Bulk scan. We handle the rest.
Scan everything at once
Open all your mail, stack the letters, and run them through your scanner as one batch. 100 letters, 200 pages, one PDF.
Upload and walk away
Drop the PDF into ComplyPost. Every page is read automatically and our AI detects where each letter starts and ends — no manual splitting.
Review in seconds
Each letter appears as a card with the sender, matched client, priority level, and a one-line summary. Confirm, adjust, or reassign with a click.
Deliver automatically
Hit send. Every letter goes to the right client by email with the PDF attached. Track delivery, bounces, and deadlines from one screen.
NO MORE WAITING
Start reviewing while the rest are still processing.
ComplyPost works through your upload as you watch. Each letter appears in your review queue the moment it's ready — you don't have to wait for the whole batch to finish.

WHY WE BUILT THIS
I got tired of scanning letters.
I work as an accountant at a firm in North London. Every morning, the same routine — open the post, read each letter, scan them one by one, email them to clients individually. For 200+ registered office clients, this was hours every week.
I couldn't find a tool that solved this specific problem, so I built one. ComplyPost is the software I wished existed. Built by someone who actually does this job.
