How long does it take for E-Mail to be delivered to another party?
While E-Mail is often instantaneous, the speed in which it can be sent to another party depends on the way mail is delivered to that person, and whether or not that person’s provider has fast mail servers. Many providers “queue” mail, meaning that messages are not delivered to customer’s mailboxes as soon as they are received due to using an oversaturated mail server. It is quite common for America Online and Prodigy to “queue” or delay mail. Messages sent to customers on those providers can potentially take up to several days to be delivered.
