Turn Slack Conversations Into Email Archives

Slack is ephemeral. Email is forever. This workflow creates a Gmail draft every time something important is posted in your key channels, so you have a permanent, searchable record.

Trigger

Channel Message Received

Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.

Action

Create email draft

Creates a gmail email draft, supporting to/cc/bcc, subject, plain/html body (ensure `is html=true` for html), attachments, and threading.

Why this helps

Important decisions and discussions happen in Slack channels, but Slack's search is clunky and messages get buried. You can't reliably find the context months later.

  • Build a searchable email archive of all critical discussions
  • Reference past decisions and context without switching to Slack
  • Preserve conversations that might get deleted or archived
  • Reduce cognitive load of finding information scattered across tools

Setup

Build it in a few focused steps.

  • 1Connect Slack and Gmail.
  • 2Create an automation: 'When a message is posted in [channel name], create an email draft with that conversation.'
  • 3Choose Channel Message Received as your trigger, and Create email draft as your action.
  • 4Specify which channels trigger this (e.g., #decisions, #launches, #client-feedback).
  • 5Check your Gmail drafts folder; Notis will create one per important message.

Questions about this workflow

Which channels should I set this up for?

Start with your highest-value channels: #decisions, #client-feedback, #product, #launches. You can add more later.

Will every message create a draft?

Yes, unless you add a filter (e.g., 'only messages with 3+ reactions' or 'only messages containing [keyword]').

Can I send these directly as emails instead of drafts?

Absolutely. Notis can send them to a specific email list or folder. Just let us know in the setup.
