how will i know my Transaction serial number from free lotto that i have won?

Answer 1

What do you mean? I hope you aren't referring to those scam emails that are from Nigeria, Canada, etc. because they are scams! Don't fall for those. You cannot trust emails like that. If they are from a person you don't know and don't include a ".net" or ".com" then they are phony and you need to delete them at once without opening them.
