Notifications are bundled and sent once every 15 minutes or once an hour, depending on your preferences.
You can send a reply to a Slack message from the related email notification.
Note: It’s not possible to receive email notifications for all new messages.
Configure your email notifications
From your desktop, click your workspace name in the top left.
Select Preferences from the menu.
Under When I'm not active on desktop, tick or untick Send me email notifications for mentions and direct messages. If ticked, choose how often you’d like notifications to be delivered.
Tip: You can also manage your email subscriptions to adjust how often you receive news about Slack apps and features, opportunities to provide feedback or Slack tips.
Reply to Slack messages from email notifications
If you receive email notifications from Slack, you can reply to them to send messages back to Slack.

The next time that you open Slack, you’ll see your reply in the appropriate channel, thread or direct message. If a teammate replies, you can continue the conversation in Slack or reply by email again.
