Why do suppliers of industrial equipment and accounting courses like spam so much?

Question

Fight against spam

A philosophical question. Once again, looking into the spam folder (sometimes I look in order to detect false positives, and sometimes not in vain) I thought. In my opinion, this is a specific developed phenomenon. Here I am writing just to discuss, do not judge strictly who does not like it.
The subject itself: probably the lion's share of Russian-language spam is an advertisement for industrial and construction equipment and materials and accounting seminars. Both are necessary (the first is in itself, the second is relevant in the conditions of constantly mutating and growing Russian financial legislation). But I, for one, will not work on principle with people who advertise in this way, even if I accidentally read their letter. Are there really no more effective platforms for promoting such things? Why are they so into this spam rested? And more or less serious people, it seems, do not sell Viagra, but are engaged in such indecency ...
The topic is by no means from the series “I am indignant” - I, in general, do not care what is swarming in the trash, but I became curious.

Answer 1

I get other spam - so the pattern is more complex than "suppliers of industrial equipment and accounting courses love spam so much."

Answer 2

Most likely, your address was included in some radio market database like “1000000 addresses of Moscow enterprises”.

Answer 3

They do not understand Internet marketing and are not going to. We heard that advertising is spam in the mail and falling windows everywhere. Plus, impressive numbers of spammers - such as "mailing to a hundred million subscriber base", and a modest price for mailing.
There is hardly any sense from it, so the conclusion is made like “f *** about your internets, nothing works there” In general,
in order to stop spamming, you need to train :)

Answer 4

Something tells me that everything that is advertised in this way is not at all big companies, but some kind of sharashka offices. A lot of beautiful words, a lot of tinsel, but in fact "zilch". I don’t know if the popular saying has long been forgotten ... “a good product does not need advertising,” especially this one.

Answer 5

1. spam was effective at the beginning of its development. A couple of years ago, I met people, usually older than 40-50, who often read spam and put the “important” in the folder “necessary”.
2. yes, I have no idea who sees this spam at all. I have both corporate and personal gmail, I don’t see spam in it. Unless sometimes, for the 3rd time, a spam letter in Arabic comes. Even translated for the sake of interest.
3. But I've dealt with a lot of small businesses in the past, and I've seen a lot of companies that don't have the money for a marketing and online promotion consultant. Such companies really find contacts of spammers in spam and spam their services through them. And, they really believe that this will bring some kind of influx of visitors.
In general, this is just a slightly different level of business, and it still lives, along with SEO and the context of plastic windows with exorbitant prices for this same context, along with spam in offline mailboxes at home.
This is done until it brings at least some result. Otherwise they wouldn't do it.

Answer 6

$url = 'www.site.ru/shop/dushevye-kabiny/?producer_id=1177';

if( preg_match('/producer_id=(\d+)$/', $url, $matches) ) {
  echo $matches[1]; // 1177
}

But I don't think you should use regular expressions... when you can just use $_GET

Answer 7

echo $_GET['producer_id'];
do you need it?

Answer 8

Read about $_GET and $_POST

Answer 9

echo "<!--". implode("", $brands2) ."-->";I just wanted to bring it out, see what happens.

For parsing url there is a parse_url() function. It divides the url into its component parts and writes them into an associative array. After executing:
$result=parse_url(' localhost/?a=1&b=2&c=3 ');
$result['query'] will contain a=1&b=2&c=3.
There is a parse_str() function for parsing url parameters. After execution:
parse_str('a=1&b=2&c=3',$params);
$params will contain an associative array with parameters.
