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.

When Netcore Cloud fires Setup Webhooks, FlowMattic runs Send Channel Message in Slack with the data from that event.

Netcore Cloud 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 template
Post Netcore Cloud webhook events to a Slack channel
Each 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.
Send bounces and spam reports to the deliverability channel
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.
Setup Webhooks→Router→Send Channel Message
Post one line per event when a call holds several
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.
Setup Webhooks→Iterator→Send Channel Message
Upload a batch of events to Slack as a CSV
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.

Flag unsubscribes from your key list privately
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.
Explain a spam complaint before it reaches the team
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.

Why run this pair with FlowMattic
Netcore Cloud and Slack connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.
Deliverability problems surface early
Bounces and spam complaints reach the people who can pause a send or fix a list, while the campaign is still running.
Large sends cost nothing extra
Runs are unlimited on every FlowMattic plan, so a campaign that returns thousands of events needs no bigger plan.
Recipient data stays with you
Email addresses in each event pass through your own WordPress server on the way to Slack, not through an outside automation account.
Common questions
How do I connect Netcore Cloud to Slack?
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.
Can bounces and clicks go to different channels?
Yes. Add a Router after the trigger that checks the event type, with a Slack step and channel on each path.
Will a big campaign flood the channel?
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.
Can I keep a record as well as the alert?
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.
Does this change anything in Netcore Cloud?
No. The workflow only receives the events Netcore Cloud sends and posts them to Slack. Lists, suppression and sending stay as they are.
