2 steps

TRIGGER

GMass · Email Opened

The workflow starts automatically when an email is opened in GMass. FlowMattic captures that data for the steps below.

ACTION

Slack · Send Channel Message

Slack — post or Schedule a new message to a specific #channel. Data is mapped from earlier steps; connect your Slack account on import.

Why this workflow

Import the JSON, connect your accounts, and go live in minutes. Every step is pre-mapped — you only add your own credentials.

Self-hosted on your WordPress install. No per-task fees, no data leaving your infrastructure, no monthly SaaS bill.

Open it in the visual builder and reshape it — add branches, swap apps, insert filters. A starting point, not a cage.
