Here are the tips I use in my own workflow across email, Slack, and calendar.

Emails
- Mobile app. Download the mobile app for your email service so you can manage your inbox on the go.
- Archiving and inbox zero. Archive emails you’ve dealt with or no longer need to act on. Aim for inbox zero so your priorities stay visible.
- Snooze. Snooze emails to clear them from your inbox and bring them back when you’re ready to act.
- Unsubscribe. Unsubscribe from newsletters and mailing lists you no longer read.
- Filters and labels. Set up filters and labels that sort and prioritize incoming emails automatically.
- Acknowledgment replies. Reply promptly to let senders know you’ve received their email and are looking at it.

Slack
- Install the apps. Keep Slack on your phone and desktop so you can reach your team wherever you are.
- Mute channels. Mute low-priority channels and keep notifications on for the important ones.
- Leave channels. Every so often, leave channels that are no longer relevant to your work or interests.
- Sidebar sections. Group channels into sections by team, project, or topic so they’re easier to find.
- Emoji acknowledgments. React with an emoji to acknowledge a message without typing a reply.
- Slack status. Set your status so your team knows when you’re available and what you’re focused on.
- Save for later. Save important messages or threads with Slack’s “save for later” feature.
- Scheduled messages. Schedule messages to send later, so they land on time even when you’re offline.

Calendar
- Sync across devices. Keep your calendar synced across your laptop and phone.
- Mobile apps. Install the calendar app on your phone for quick access to your schedule and notifications.
- RSVPs. RSVP to every invite so organizers know who’s coming.
- Default reminders. Set default reminders for all events so you have time to prepare.
- Arrive early. Join meetings 2-5 minutes before the start time.
