I would love to learn this process! I've repeatedly asked for a certain mailing to stop and it hasn't ceased.
For example, I'm currently getting no less than 3 letters per week from Spectrum (formerly TWC) promoting their new triple-play plans. I drop all of them in the recycling bin.
I couldn't care less about their bottom line, but I do care about the environmental impact.
At 3x per week, it probably costs them around USD$0.80/week (postage, paper, printing, etc.) to send those 3 letters. Call it USD$1 to make the math easier. I currently pay about $9.03/week. If I upgraded, it would be at least 3x that amount.
I'm not sure how to calculate the profit they would gain after an upgrade, but I can't imagine it would take more than 2-3 months for the new rates to more than cover the mailing fees for an entire year of their letters.
And yet, I'll never upgrade and I hate the waste caused by their practices.
In the ones like Dell (which I've also experienced in the past), I suspect there's some metric involved for getting the most contacts for "coverage". The reality is unless they were tracking my moves to different companies, there could be different people with the same name. In that sense, I'm very glad they can't correlate with employment data.
There's also the idea that sending to multiple people within a company means someone may see something they want and try to go through the procurement process because of the catalog, rather than because "IT" says it's time for a refresh.
Not that I agree with any of those practices, for a number of reasons, but I could understand the case for them.
Putting on my cynic hat, buying lots of newspaper, television and radio ads is a good way to keep the media on the sidelines instead of criticizing the incumbents.
I am doubting this is enforced in any meaningful way. I don't doubt there is a well-detailed process however the US Post Office's bread and butters seems to be Dell Catalogs and Southwest Airlines credit card offers. This fact is what killed Outbox:

We don't even want _one_ of them. It's not like we're going to see a new printer in a catalog and say "hey, sounds like a great buy!"
But in the meantime, tens of millions of potential customers times any reasonable fee seems more than enough to build a substantial business on.
You could tempt people in with a cheap fee to let them send in a few pictures of junk mail and stop those. (As you get more, find the biggest sources and automate or batch them so that they cost you almost nothing, which will pay for the higher-effort ones. Have an upper bound on effort expended, and tell people that they don't pay if you can't remove them.) You could then track down the underlying sources, and if you successfully identify them, contact the customer, and give them enough information to decide to pay you for a higher-end service to get them removed from those sources (and keep them removed).
The value that gets people to keep paying you would be a steady stream of reports of "we found this source leaking/selling your information, here's what we did about it". It'll take you years to track down all such sources and find paths to remove them; you will likely end up having to fund some legal work and possibly even a lawsuit or two, which will give you a giant pile of publicity.
(As one example of something much easier for a company optimized for the process to do than an individual: the USPS has a detailed process for formally putting a company on notice for mailing someone who has specifically unsubscribed, and that process ends in massive fines for continued mailing to that person. I read a report of someone doing that to stop receiving persistent Dell catalogs.)
If you're sufficiently creative, you could even pitch this as a service to marketing companies. You have a list of people who will not buy anything via direct mail, and who will despise any company that they receive such mail from. Convince the sources of postal spam that removing those people from their list makes the rest of their list more valuable. Convince the downstream customers of those sources that using your list directly is far more convenient for them than dealing with opt-outs from every individual on it.
That also gives people a continued incentive to pay to remain on that list.
