The basic rule of any correspondence (let alone Russian girls) is mentioned in the Bible: Treat people the way you would like them to treat you. In other words, write the letters you would like to get.
The concept of your first letter
It must include some information. If you are writing a letter you have at least seen her picture. If you are curious you have read her profile and know about her hobbies, preferences and so on. You are already communicating with her in your thoughts but she knows nothing about you. You are a clean sheet of paper for her or something you have written on this sheet!
If you write something like, «Hi there! I am Michael from Canada. I will glad to receive a letter from you» you can expect the answer of the most desperate woman or a scam. Want it?
Introduce yourself. Tell her what exactly you liked in her profile. Tell her about yourself in a nutshell (your character, likes and dislikes, life values, the traits of a person’s nature that you appreciate). You are intended to marry, so tell her your ideas about marriage on the whole.
Just don’t give too much information. It doesn’t sound good if you start describing the whole history of your family in the first letter so that it takes 9 pages (no matter how exciting it can be().
Avoid monologues. Ask her some questions about her, her country, work, pets and so on. Let her feel your sincere interest!
A little humorous shade is always appreciable! Be friendly and romantic. And of course, say compliments!
Make sure not to forget to attach your pictures! It will help you avoid misunderstanding in future. Evidently, your picture must be of hi-fi quality.

It does not further falling in love with you!( Children or pets are allowed. But don’t forget to comment on them.
Ask your woman to answer you even if she rejects your attention. Of course, all serious agencies can give you this service, but if you mention it in you letter the woman you are writing to will realize you are serious. Perhaps, this very fact will shatter her doubts concerning your decency!
