Task: Draft and save vacation-reply emails for the relevant threads. For every unread email, create a saved draft telling the sender that I am on vacation and will respond as soon as possible. For every read email received after Jan 20 that has not already been notified, create a saved draft telling the sender that I am on vacation. Do not send the drafts.
Hint: For unread emails, create and save a draft reply notifying the sender that I am on vacation and will respond as soon as possible. For read emails, check the received date; if the email was received after Jan 20 and the sender has not already been notified, create and save a draft reply notifying the sender that I am on vacation. Do not send any emails.
