Six stages, three of which can bin it. Here is the journey, and the decisions that survive it.
Nobody writes about this from the sender's side. Search it and you get mailroom security vendors and a dictionary. So here is the actual journey an envelope makes inside a mid sized British company, stage by stage, with the point at which each decision gets made.
Nothing here is about you. Format and postage decide speed, not treatment. A Large Letter costs more and arrives the same day as a Letter. If your item is thick enough to change format, that is a cost decision rather than a delivery one.
Post arrives in a bundle. In a small business it goes straight onto somebody's desk and the rest of this page is academic. In anything larger, a person sorts it, and that person spends roughly two seconds per envelope.
This is where letters die. The sorter is not reading, they are categorising: personal post, business post, or marketing. Three things put you in the marketing pile before anyone has opened anything.
A real stamp and a handwritten looking address flip the same envelope into the personal pile. It is a small difference in cost and a large difference in outcome.
Now the name matters. A named person gets carried to a desk. A job title alone gets carried to whoever the sorter thinks owns that title, which in a company of any size is a coin toss. Put both on the envelope: the name gets it to the right person, the title saves you if that person has left.
Do not write Private and Confidential. On a marketing letter it reads as an attempt to bypass normal handling, and whoever opens it knows exactly what you did. It buys one delivery and costs the impression you were trying to make.
Senior people often do not open their own post. Their assistant does, and assistants are extremely good at recognising a letter designed to trick them into passing it up. What gets through is not clever packaging. It is a first line that is obviously about that specific company, written in a way that makes forwarding it the easy decision rather than the risky one.
If you have got this far, you have earned about half a minute. Which is why the first sentence carries almost all the weight, why the letter should be short, and why a QR code or a simple web address gives the reader somewhere to go that a sheet of paper cannot.
Rockkt prints the address in a handwriting style, keeps the envelope plain, and builds the first line from something specific to that person rather than a merge field. None of that is clever. It is just the unglamorous list above, done the same way every time, at a volume a person could not sustain by hand.
