What Really Counts As Spam
What counts as spam isn't decided by law. It's decided in the first seconds a recipient sees your email. Here's the test that actually applies.

What counts as spam and what counts as legal email marketing are not separated by law. They are separated by what the recipient feels when he sees the letter in the inbox.
Why the Formal Definitions Fall Apart
Formal definitions are enough. Wikipedia calls spam the sending of advertising or other information to people who have not expressed a wish to receive it. Igor Ashmanov gives a narrower definition: anonymous unsolicited mass mailings, most often of an advertising character.
Both definitions work on paper. In practice they fall apart at the first question. Did the recipient express a wish to receive this particular letter? Is the sender anonymous? Is this information commercial or not? The answer depends on whom you ask, a lawyer or the recipient himself.
The legal side of the question is real, but useless for a marketer. It does not matter to the recipient whether the checkbox was ticked in the registration form. He either opens the letter or sends it to spam, and he does this in a second, without lawyers.
The Test That Actually Decides
Here is the test that really works. A letter falls into spam if at least one of three conditions is met: it is not interesting to the recipient, it consists only of advertising, the recipient did not ask for it to be sent. A match on any of the points, and the finger reaches for the "Spam" button.
The problem is that this finger fires even where there is formally no spam. A ZeroBounce survey of over a thousand respondents in 2026 showed: 80% of people mark a letter as spam simply because it "looks like spam." Not because the law was broken or the address collected illegally. Because the letter did not pass a visual and content check in the first seconds.
This changes what is worth looking at. An address in the mailing base says nothing about a person's loyalty. It is a line in a table, nothing more. Email marketing works to change this: to form trust and interest, not simply to deliver a message.
What a Stolen Address Costs You
A stolen or bought address destroys this task at the start. Trust cannot be built with a person who does not expect letters from you and does not understand where you got his contact. The outcome is predictable. He sets up a filter, and all your letters, including useful ones, automatically go to the "Spam" folder.
The conclusion is simple. Do not buy or steal the email addresses of potential clients. This is a statement about how trust works, not a legal recommendation.
