The problem
Plenty of correspondence still has to arrive on paper. Statutory notices, arrears letters, anything where proof of postage is the point — none of it can be replaced with an email. But the process around sending one has barely changed: print it, find an envelope, fold it, buy a stamp, walk to a post box, and queue at a counter if you need proof. That is half an hour for a single letter, and a week of somebody's time for a run of a few hundred. The alternatives are the wrong shape for most businesses. Mailing houses want volume commitments and an account-opening process, which prices out the business sending forty letters a month, and prices out entirely the one sending a letter a year.
The approach
Move the whole physical step behind a web page and an API. The letter is written in the browser or uploaded as a PDF, then printed, folded, sealed, franked and handed to Royal Mail from a UK facility the same working day before three o'clock. One all-in price covers printing, envelope and postage, from Second Class through to Special Delivery, with tracked and signed-for where proof matters — and the page count that sets the price is counted from the actual document rather than estimated, with a page-by-page proof shown before anyone pays. No account, no subscription and no minimum, because the same engine should serve one letter and a mailing run of thousands. The API exists for the same reason: statutory notices and arrears letters are generated by software, so the sending should be triggered by software too.
Who built it
Send Letters Online was founded and built by Abdul Rehman Sandhu, a qualified accountant and technology advisor working with businesses globally. The same diagnostic approach behind this venture is the one applied in client engagements.
