as my title mentioned I am searching for a solution to get all email addresses that I have received from people and saved inside a certain folder in my Thunderbird.
I need them for marketing purposes, because those email addresses belong to people I have done business with.
Thanks for help.

You can use Message Filter in order to organize your messages.

Updated:
Select all the emails in that folder and saved them on a directory as a *.eml
file format.
In the terminal: cd /path/to/eml/directory
Then run:
find . -type f -exec cat {} \; | nl | grep "From" | grep -o '[[:alnum:]+\.\_\-]*@[[:alnum:]+\.\_\-]*' | uniq -ui | sort > collected-emails.csv
Now, All the collected emails will be saved in collected-emails.csv
