Inbox automation is the process of setting up workflows that complete repetitive email tasks automatically, freeing up time for more important work. By identifying common time-wasting emails such as frequently answered questions, availability requests, and newsletters, individuals can automate their inbox using tools like TextExpander, Outlook 365 Quick Parts, Gmail templates, Calendly, Mixmax, and x.ai. These tools help reduce the amount of time spent on email management, allowing individuals to focus on more productive tasks. Additionally, automating responses to frequently asked questions, sharing availability automatically, getting promotional emails out of the inbox, responding to fewer unsolicited requests, and moving tasks out of the inbox can also significantly improve productivity.
