Prioritize Slack messages that have important email backups

When a critical email lands in your inbox, Notis stars the related Slack message so your team instantly sees it's now urgent and needs attention.

Add a star to an item

Stars a channel, file, file comment, or a specific message in slack.

Why this helps

Important emails arrive while teams are discussing things in Slack, but without a connection, the Slack thread stays normal priority and the urgency gets missed.

  • Create visual urgency in Slack when corresponding emails arrive without requiring manual flagging
  • Give teams an at-a-glance sense of what needs immediate attention
  • Build a habit of checking starred items to catch important email-backed developments
  • Reduce the need for verbal reminders about email-related urgencies

Setup

Build it in a few focused steps.

  • 1Connect Gmail and Slack to Notis.
  • 2Create an automation: ask Notis 'When I receive an important email, star the related Slack message' or use the portal.
  • 3Describe the outcome: 'Star the Slack item from the sender or about this topic, making it visually stand out.'
  • 4Select the trigger: New Gmail Message Received from key contacts or domains.
  • 5Choose a Slack channel for run reports.
  • 6Test by having a colleague send an important email and seeing if the related Slack message is starred.

Questions about this workflow

How does Notis find the related Slack message?

Tell it in your prompt. Examples: 'star messages from the email sender', 'star messages that mention the email subject keywords', or 'star messages in #client-updates about this sender'.

What if there's no related Slack message?

Notis will acknowledge the email arrived but won't star anything. You can refine your prompt to post the email to Slack first if needed.

Can I control which emails trigger stars?

Yes. Specify in your prompt which emails matter (e.g., 'only from external senders' or 'only if the subject line contains investor-related keywords').
