A few questions about phishing

[x_mode]

Hello everyone. I recently started working on phishing sites. I have created a copy of my country's bank website and would like to ask for some tips, for example:


1) What's the best way to send a message?
sms or mail?
(I would be grateful if you recommend several platforms or programs for this)
2) What should you pay attention to when writing a message?
for example - your account is blocked or receiving money from any source and others ...
3) Should the text be short or long?
4) What mistakes do beginners often make?
5) How can people notice that the site is fake?
6) What sites can do to make it harder to copy a site?
7) Do sites have the ability to find out that the site was copied?
8) What are the ways to copy sites?
9) What platforms can help me with the creation of sites?

Maybe the questions are trivial, but I would like to hear the opinion of those who have already done this.
Naturally, before publishing these questions, I read a significant amount of topics on this question, so I have some information about how it works and how it should work.
Of course, I will continue to study and read to learn something new.

Thanks to whoever read this and spent their precious time.

Have a nice day everyone!
