Email Web Application provides:

1- sending emails 
2- staring emails 
3- mark an email as important 
4- making a custom folder where you can put some emails but up to 1 folder 
5- trashing emails 
6- make an email as draft 
7- resend the drafts 
8- sending attachments with email 
9- deleting the trashed emails after about 30 days from the trashing process date 
10- searching for some users 
11- adding users as friends

Design Decisions made:

- Sending messages can be from one user to multiple users
- User can use only one custom folder to drag the needed files inside
- In searching for messages by "to" attribute if you put multiple users, you will get messages to either of them (inclusively)
