mac mail question

[DaKyd55]

i have a new computer.... i had a verizon mail account on my old one, and i entered it in mail on the new one. it came up with all of my unread emails but i need one that i had read already as it has a serial number in it. how can i get access to the unread?

thank you

can you access your email from the verizon site?

I have a hotmail account set up through the mail app, but I can also access my emails by going to hotmail.com.
