Connect FlowMattic Forms and Slack
FlowMattic Forms is the form builder inside FlowMattic, so a submission is already workflow data the moment it is sent. Slack is where your team sees it. Post enquiries to the right channel, flag suspicious ones, message colleagues directly and note on the submission what happened. It suits sites of any size that want form alerts without another plugin.

FlowMattic Forms and Slack workflows you can build
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.

A Router reads the department or topic field, so sales questions go to the sales channel and support requests to support, instead of everyone reading everything.

A Branch checks the message for links. Spam-like entries go to a review channel instead of the main one, so the team is not interrupted by junk.

For staff forms such as IT or design requests, Find User by Email finds the owner chosen in the form and Send Direct Message pings them privately.

Share uploaded files in the channel with the entry
When someone attaches a brief or screenshot, Upload File posts it into the channel, so the team can open it without logging in to WordPress.

Note on the submission that Slack was told
After the message is posted, Add Note to Submission records which channel got it, so anyone looking at the entry later knows it was passed on.

Remind the team to follow up on hot leads
A Filter passes enquiries with a large budget or urgent timeline, and Add Reminder sets a Slack reminder so nobody forgets to call back.

Triggers and actions in this pair
A trigger starts a workflow. An action is something FlowMattic does in the app as a step.
Good to know
- FlowMattic Forms needs no connection, because the form and the workflow live in the same plugin. Only Slack is added under Connects.
- These workflows send entries to Slack, so a reply in Slack does not reach the person who filled in the form. Answer them by email or add an email step.
- Long answers make long channel posts. Text Formatter can cut the message field to a short preview, with a link to the full entry in wp-admin.
Triggers (1)
- New Form SubmissionTriggers whenever the selected FlowMattic form receives a new submission. Every field value is exposed as a workflow variable.
Actions (3)
- Set Custom ResponseReplace the form's success message with custom text or HTML — ideal for showing an AI-generated result back to the visitor.
- Set Custom Redirect URLSend the visitor to a custom URL after they submit the form, instead of showing the success message.

Why run this pair with FlowMattic
FlowMattic Forms and Slack connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.
No extra form plugin
The form, the workflow and the Slack message all run in FlowMattic on your WordPress site.
Every entry, same price
Runs are unlimited, so a busy contact form posting hundreds of messages a week costs the same as a quiet one.
Entries stay on your site
Submissions are stored in your WordPress database and only the fields you choose are sent to Slack.
Common questions
How do I send form submissions to Slack?
Create a workflow with the FlowMattic Forms New Form Submission trigger, add Slack Send Channel Message, choose a channel and place the form fields in the message text.
Can different answers go to different channels?
Yes. Add a Router after the trigger with a path per answer, such as department or product, each with its own Send Channel Message step.
Can I keep spam out of Slack?
Yes. A Branch or Filter can check for links, banned words or empty fields, so suspicious entries go to a review channel or stop altogether.
Can the form show a custom thank-you after posting to Slack?
FlowMattic Forms has Set Custom Response and Set Custom Redirect URL actions, so the same workflow can change what the visitor sees after they submit.
Do I need the Slack user's ID to DM them?
No. Find User by Email looks the person up by their email address, and Send Direct Message uses the ID it returns.
