Netcore Cloud can report delivery and engagement events to a webhook. FlowMattic receives them on your WordPress site and posts them to Slack, with bounces and spam reports in front of whoever owns deliverability and clicks in front of the campaign team. For marketing and email operations teams sending through Netcore Cloud.

1. TriggerSetup Webhooks2. ActionSend Channel MessageWhen Netcore Cloud fires Setup Webhooks, 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 templateEach event Netcore Cloud sends posts the recipient, event and campaign to one channel, so the email team sees delivery problems while a send is still going out.

View the template A Router reads the event type. Bounces and spam complaints go to the people who protect the sending domain, clicks and opens to the campaign channel.

When a single webhook call carries a list of events, Iterator steps through the list so each bounce or unsubscribe gets its own readable message.

For large sends, CSV Creator turns the events of one call into a file and Upload File posts it, so the channel gets one attachment instead of hundreds of lines.

A Filter keeps only unsubscribes from the list or campaign you name, and Send Private Channel Message tells the account team without filling a public channel.

An AI Agent reads the event and writes a short note on what it means for the sending domain and what to check next, so newer team members know what to do.

At the end, each event Netcore Cloud sends to your webhook appears as a message in the Slack channel you choose.

A trigger starts a workflow. An action is something FlowMattic does in the app as a step.
Netcore Cloud and Slack connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.
Bounces and spam complaints reach the people who can pause a send or fix a list, while the campaign is still running.
Runs are unlimited on every FlowMattic plan, so a campaign that returns thousands of events needs no bigger plan.
Email addresses in each event pass through your own WordPress server on the way to Slack, not through an outside automation account.
Create a FlowMattic workflow with the Netcore Cloud Setup Webhooks trigger, add its URL as a webhook in Netcore Cloud, send a test event, then add Slack Send Channel Message with the fields you want in the post.
Yes. Add a Router after the trigger that checks the event type, with a Slack step and channel on each path.
It can if every open and click posts. Filter out the engagement events you do not need, or collect a call's events into a CSV and upload one file.
Yes. Add a Google Sheets, Airtable or WP Tables step to the same workflow, so Slack carries the alert and the table keeps every event for later.
No. The workflow only receives the events Netcore Cloud sends and posts them to Slack. Lists, suppression and sending stay as they are.
