How can using email help you in the future? How do you think businesses use e-mail? Well i think it could help by sending mails to your teacher like when your in collage. Like you could send an email to misses Jaime.That could help you alot because if you dont know how to email then how can you comtact your Idea teachers.Well it could also help you in a type of way like when you want to contact a friend if you dont know how to email well y ou cant contact him. Also like if you dont know the safety of email you may open a spamed messege.
