Post every form submission to a Slack channel
Small teams put all website enquiries in one channel such as #leads, where anyone can pick one up and reply in a thread to show it is handled.

Connect Contact Form 7 and Slack
Contact Form 7 collects the message and Slack is where your team will actually see it. FlowMattic posts each submission from your WordPress site into the right channel or straight to the right person, with the fields laid out the way you want, so enquiries get answered instead of sitting in a shared inbox.

Contact Form 7 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.
Ready-made templateSend sales enquiries to Slack and support requests by email
A Router reads the subject. Sales messages go to the sales channel, while support and general questions go to the right mailbox, and each submission takes one route only.
New Form SubmissionRouterSend Channel MessageEmail (SMTP)
View the template Message the right person by department
The form has a Department dropdown. A Lookup Table turns the choice into a colleague's email, Slack finds that user, and the enquiry arrives as a direct message.

Set a Slack reminder to call back each enquiry
Freelancers who handle enquiries alone get a Slack reminder with the person's name and number, so a callback request is still there after a busy day.

Post a one-line AI summary of long messages
Some visitors write several paragraphs. An AI Agent sums up the request and its urgency in one line, posted above the full message so the channel stays easy to scan.

Keep job applications in a private hiring channel
A Filter passes only submissions from the careers form, which are posted to a private channel so applicants' details are seen by the hiring team only.

Set up: every submission to a channel
Once finished, each Contact Form 7 submission is posted as a message in the Slack channel you pick.

Add Slack Send Channel Message, pick the channel, and build the text from the captured fields, for example name and email on the first line.
Test and switch on
Run the step, check the message in Slack, then switch the workflow on.

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
- Contact Form 7 has one trigger and Slack has no triggers here, so workflows run one way: from the form into Slack.
- The mapping uses Contact Form 7's default field tags such as your-name and your-email. If your form uses other tag names, map those.
- Spam that gets past your form's protection will reach Slack too. A Filter on the message, for example dropping entries full of links, keeps the channel clean.

Why run this pair with FlowMattic
Contact Form 7 and Slack connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.
Submissions go from your site
Form data travels from your own WordPress server to Slack, and nothing is stored by an outside automation account along the way.
Busy forms, same plan
Runs are unlimited, so a form that gets hundreds of messages a day costs the same as one that gets two.
One form, many destinations
A single submission can go to a channel, a DM, a reminder and an email, each chosen by what the visitor typed.
Common questions
Can Contact Form 7 send submissions to Slack without a plugin add-on?
With FlowMattic installed, yes. You choose the New Form Submission trigger, pick your form and add a Slack step. There is no extra Contact Form 7 add-on and no Slack app to code.
Can different forms post to different channels?
Yes. Build one workflow per form, each with its own channel, or use one workflow with a Router that checks which form was submitted and picks the channel.
Can the message include a link to reply by email?
Yes. Put the visitor's email from the your-email field in the message. Slack shows it as a mail link, so a teammate can click it and answer from their own mail app.
Can I post to a private channel?
Use Send Private Channel Message and choose the channel. If it does not appear in the list, check that the Slack account you connected is a member of that private channel.
Does it work with file upload fields?
The fields you see in the captured test entry are what you can map. Test with a file attached to see what the trigger gives you before relying on it in Slack.
