If your work revolves around email, read receipts and open tracking are a powerful tool. These features allows you to see if and when recipients open your emails and click links, so you can send friendly reminders or perfectly-timed next steps.
Rmail.plala.or.jp (ぷらら) doesn't provide open tracking or read receipts via their webmail interface, but they support IMAP, which means you can use another email program like Mailspring to send messages with read receipts and open tracking enabled.
