How to compose a successful letter to a blogger? I have written dozens of letters, but they have not open and read them? can you please to share your own experience or recommend please, some really useful articles according this topic.
Oh, I see. You mean: How to convince a perfect stranger that they should do something that's to your financial advantage, and how to get past all the scammers who are inundating the blogger's mailbox with email proposing exactly the same thing, only your scheme is legitimate while the others aren't.
If a blog has a comment thread, and you've spent months establishing yourself as a worthwhile commentor who always has useful, interesting or entertaining things to say, then maybe the blogger will recognize your name in their inbox, and will at least open the email. (Incidentally, how do you know yours haven't been read? Wasn't that the whole point of making "load images" a separate, voluntary function--so senders can't automatically tell if their email has been read?)
