Most used workflows for Slack + Gmail
Convert Slack DMs to Email Drafts

Every morning, Notis compiles yesterday's key Slack messages into an email draft you can review and archive.
Reply to Gmail Threads from Slack DMs
When someone DMs you in Slack, Notis finds the related Gmail thread and drafts a reply so your response stays in one place.
Notify Team of Form Submissions via Email Draft
When an external form or webhook triggers, Notis creates an email draft with the submission details, keeping your team in the loop.
Auto-Organize Emails by Slack Channel
Messages from specific Slack channels are automatically labeled in Gmail so your inbox mirrors your team structure.
Clean Up Gmail Labels When Slack Reactions Are Removed
Undo a Slack reaction and Notis removes the corresponding Gmail label, keeping your inbox clean and reactive.
Supported Triggers and Actions
Notis builds workflows that link Slack to Gmail. A trigger fires from one place; an action lands in another.

Gmail actions

Four ways to start an automation.
A trigger is the event that kicks a workflow off. Notis supports four kinds: an event in a connected app, an inbound webhook, a recurring schedule, and soon, your own database.
Integration triggers
Fire when something happens inside a connected app. New Notion page, Stripe charge, Linear issue: any of 1,000+ apps can start a workflow.
Webhook triggers
A unique URL per workflow. Anything that can send an HTTP POST can start an automation, including no-code tools that speak webhooks.
Recurring triggers
Cron-style schedules run a workflow on the clock. Daily standups, hourly syncs, business-hours-only digests: the workhorse of Notis.
Database triggers
Watch a row, query, or threshold in your own database and fire the moment the data changes. Row inserted, value crosses a limit, query starts matching.
Classic automation breaks. AI adapts.
Same triggers and actions, smarter middle. AI handles the fuzziness that breaks traditional Zapier-style workflows the moment a field gets renamed.
Describe it. Notis builds it.
Skip the visual builder. Tell Notis what you want, in plain English. It writes the workflow, you review and deploy.
