An email system may include at least one subscribed mailbox server having a plurality of subscribed mailboxes and sending a new mail indication upon receiving a new email message, and a plurality of mobile wireless communications devices. The system may further include at least one email aggregation server for polling each subscribed mailbox for email messages based upon receiving a respective new email indication therefrom, and forwarding the email messages to respective mobile wireless communications devices. The at least one email aggregation server may perform a fallback polling of each subscribed mailbox based upon not having polled the subscribed mailbox for a threshold fallback time, and stagger respective initial fallback polling times of the subscribed mailboxes upon start-up.
