Looking out for scams!

[cherophi]

Hi, I just joined fiverr a day or so ago to try create a side hustle for money. In a pretty short amount of time, I got 2 messages saying they were interested in commissioning me for my art and immediately asked for my email. I went along and gave my email, thinking that was normal in order to discuss things, but figured out after that it was a scam because I saw that fiverr doesn't ask for all your credit card info in order to transfer money. Would it be safe to assume as a general rule of thumb that when some random user with no reviews on their profile messages you asking for your email, it's a scam?
