How do i spread stealer my stealer effectively?

[soru]

Currently im spreading my stealer through mass mailing but its not working that well either because im getting sent to spam or possibly if the mail apps have warnings against downloading .exe files, ive also tried sending it to high value targets on discord but it hasnt worked since discord also warns the user about downloading the .exe file even though its hidden as rcs.png. I was wondering if theres a better way to spread it to a ton of people more effectively or if theres a way to completely hide the fact that its an executable from the app without making the user manually rename the file, ive seen videos on youtube on how to hide .exe in an image or in another file but none worked for me. If someone took the time to read this and can help i appreciate it.
