Sooner or later, I will make my website, application or something that will be popular, and when this happens, I would never send users letters with congratulations on the New Year, Christmas or some other official holidays. Because they enrage me! Does anyone read them and think, “Oh! Mail.ru thanks for the congratulations, you are so attentive to me "or" Oh, the strange site on which I registered 5 years ago and have never entered, how good it is that you do not forget about me! ". I do not care about all the congratulations, the sender of which does not even know about my existence, this is just another letter with disgusting plausible spam, which I will delete without reading. I will never think that this is a sign of attention to me or respect from the site, no, no, and no, I would rather think that the site considers me to be part of an abstract gray mass for which one congratulation will fit all.
