What this workflow does

Newsletter growth is easy to lose track of when the numbers sit inside your course platform. A quick note in Slack for each sign-up helps a small team notice which launches, webinars or posts bring people in. This workflow sends that note whenever PETE records a confirmed subscription.

The PETE Newsletter Subscription trigger fires when someone submits your newsletter form and confirms their email by clicking the link in the mail PETE sends. Sign-ups that never confirm don't start a run. FlowMattic passes the subscriber's details to Slack, where Send Channel Message posts to the channel you choose with the details you map in.

Every confirmed subscription produces one message, because the template has no Filter. If your list grows quickly, consider a quieter channel so sign-up alerts don't bury other conversations. Task History logs each run if you need to see what was posted.

Course creator watching a launch

During a launch week, each confirmed PETE newsletter sign-up appears in a launch channel, so you can see interest building in real time.

Coach checking which content works

When a webinar or blog post goes out, the team watches the Slack channel to see whether new confirmed subscribers follow.

Small team celebrating growth

A dedicated sign-ups channel gives everyone a light view of list growth without anyone logging in to PETE to check.

After importing, map your own data. To keep the template universal, not every step is pre-filled. Open each step in the builder and connect your accounts and fields (channels, lists, sheets, recipients) before you switch the workflow on.

Make it yours

Changes worth making after you import it.

Sign up with a test address after import and confirm it, so FlowMattic captures the PETE subscriber data before you write the Slack message.
If the alert should go to a private channel, use Slack's Send Private Channel Message action, which is separate from Send Channel Message.
Add a Google Sheets Add New Row step after Slack to keep a dated list of confirmed PETE subscribers alongside the alerts.

Questions about this workflow

Does the Slack message go out before the PETE subscriber confirms?

No. The trigger fires only after the person clicks the confirmation link in PETE's email, so unconfirmed sign-ups never reach Slack.

Can the Slack message show the new PETE subscriber's email?

Yes, if PETE includes it with the subscription and you map it into the message. Leave it out if the channel is open to people who shouldn't see subscriber details.

Will course enrolments in PETE post to Slack too?

Not with this template. PETE has a separate Course Enrollment trigger in FlowMattic that you could use in a second workflow.
