Fillout forms collect demo requests, applications, internal requests and quiz answers. FlowMattic takes each new response and puts it in front of the people who act on it in Slack: a channel post for the team, a direct message for the owner, a reminder for the follow-up. It suits teams that already work from Slack all day.

1. TriggerNew Submission2. ActionSend Channel MessageWhen Fillout fires New Submission, FlowMattic runs Send Channel Message in Slack with the data from that event.
You build this in the FlowMattic workflow builder on your own site. See the setup steps
Each one uses only triggers and actions the two integrations ship today, plus FlowMattic's own tools. Where the library has a ready-made template, import it instead of building from scratch.
Ready-made templateThe team reads new responses where they already talk, so a demo request or an application is picked up by whoever is free instead of waiting in the Fillout inbox.

View the template A form with a topic question can feed several teams. A Router reads the answer and posts billing questions to finance, bugs to engineering and the rest to support.

For IT or HR request forms filled in by staff, look the person up by the email they gave and send them a direct message saying the request reached the team.

A Filter passes only responses that meet your bar, such as a budget above a set amount, and posts them to a private channel the leadership team watches.

When a Fillout form asks for a brief, a CV or a photo, the file goes to the channel next to the response, so reviewers open it without logging into Fillout.

An AI Agent step turns several paragraphs of answers into a short summary with the key facts, so the channel stays readable on busy days.

Slack reminds the sales rep the next morning to call the person who asked for a demo, so requests sent late in the day are not left until the weekly review.

At the end, every new response to your Fillout form appears in the Slack channel you pick, with the answers you choose.
In FlowMattic, open Connects and add Slack with the workspace account that will post the messages.
Create a workflow, choose Fillout and the New Submission trigger, and follow the connection steps shown for your form.
Fill in the form once yourself so FlowMattic captures each answer as a field you can map.
Add Send Channel Message, pick the channel and write the message with the name, email and key answers. Test the step, then switch the workflow on.

A trigger starts a workflow. An action is something FlowMattic does in the app as a step.
Fillout and Slack connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.
Sales, support and HR see new Fillout responses in Slack without checking the form dashboard or forwarding email notifications.
Routers and Filters on the canvas decide which channel or person each response goes to, based on the answers given.
FlowMattic runs on your own WordPress site with unlimited runs, so a busy launch week of responses costs the same as a quiet month.
Add a Slack connection in FlowMattic, start a workflow with the Fillout New Submission trigger and add a Send Channel Message step. Map the answers you want into the message, test it with a real response and switch it on.
Yes. Build one workflow per form with its own channel, or use one workflow with a Router that checks a field such as the form name or a topic answer and picks the channel for each path.
Only when that person is in your Slack workspace. Find User by Email looks them up from the email answer, and Send Direct Message then sends the confirmation. For outside customers, send an email with the Email (SMTP) step instead.
Yes, add an Upload File step after the message and map the file field from the response to it. Check the captured test data to see how your form passes the uploaded file.
