Very appreciate if you enlighten me about this one.
People can do it on their own but the thing is it will need phone verification code. If you need lots of emails then you will need lots of numbers too which I believe it is expensive on there country and also time consuming. Regarding the password and recovery mail, out of 10 buyers I have only one or sometimes none of them will edit the password and recovery mail (I know this one because they will ask me if they can change it and I encounter too that he needs my help in changing his password lol). Some of my buyers will open up that they use these emails for email marketing. For spamming. Others use it for social media accounts. I know there are more.
