Depends on the configuration of the email because there are two protocols POP and IMAP, the most recent protocol is IMAP, we can delete an email and this It moves to a To be Deleted folder, this happens because the email is stored in the server, but with the protocol POP the email is stored in the server and downloaded to the application, if you delete an email, this is deleted in all devices.
HTML help creates the structural overview, CSS helps in the design and an application software helps in the accessibility, editing, typing of code, but JavaScript helps to make it interactive. Thank you.
