Send this to your assistant

Create a ClickRuntime automation: whenever someone subscribes to my beehiiv newsletter, post their email and UTM source to #growth in Slack.

Paste it into your assistant. It tells you what it will send or change before it runs live.

Why use it

Why teams use this automation

A newsletter writer or a small media team using beehiiv grows by watching which posts, referrals and promotions bring readers. The subscriber count appears in the dashboard, but a single number hides the interesting facts: who just subscribed, from which source, after reading which post. A sponsor who joined from a LinkedIn post is not noticed, and the writer does not thank the reader whose referral brought ten others, because nobody saw the name go by.

When someone subscribes to your publication, beehiiv sends a webhook to ClickRuntime. ClickRuntime posts the new subscriber and their UTM source to Slack, so you can see who arrived and where they came from within seconds.

Creators with a sponsor, a partner or a small team who share the excitement of growth can use the channel as a live feed.

What you get out of it

Sources of growth are visible daily
Seeing UTM sources in the feed shows which channels bring subscribers right now. You learn which posts and promotions work in days instead of at the end of a month.
Valuable subscribers are noticed
A recognizable company or a well-known name appearing in the channel is a chance for a personal welcome. Relationships with influential readers often begin with a short reply. Many relationships with big readers start with a short reply.
Campaigns can be judged immediately
If you run a promotion on a given day, the feed shows whether subscriptions follow. You can adjust the message or the placement while the campaign is still running. You can adjust the message or the placement mid-campaign.
The team shares the progress
Watching subscribers arrive in Slack keeps a small team motivated. Everyone sees the effect of the work they do, which is harder to feel from a total on a dashboard.
Suspicious signups are caught
A burst of subscribers from the same odd source can mean bots or a bad referral program. Spotting it early protects your open rates and sender reputation. That protects your open rates and sender reputation over time.

How it works

What happens, step by step

When someone subscribes to your beehiiv newsletter, beehiiv tells ClickRuntime straight away.
The automation picks out their email and where they signed up from, or "direct" if no source was recorded.
It posts both to your #growth Slack channel.

Build your own

Need it to work differently?

This template is a starting point. Copy the prompt and change it, or describe a different automation from scratch, with your own conditions, more apps or an AI step. Your assistant writes it, tests it and runs it on ClickRuntime.

Your own rules
Conditions, thresholds, filters and exceptions, written the way you'd explain them to a colleague.
Any number of apps
One automation can read from one app and update several others. Over 248 apps are ready, and anything with an API works too.
AI where it helps
Summaries, classification, extraction and drafts use ClickRuntime's built-in AI, with no extra key.
On a schedule or on each event
Runs as often as every 5 minutes, or the moment an app sends an event, and keeps track of what it already handled.

Changes you can ask for

Act only on the items that match your own rules, and skip the rest
Add an AI step, for example to summarize, sort or draft a reply
Add another app, for example also send it to Slack
Combine it with other beehiiv steps into one automation

Under the hood

The code that runs this automation

This is the Python script that runs each time the automation starts. Your AI assistant writes it for you when you send the prompt, and you allow each step in your assistant. To change how the automation works, describe the change to your assistant and it updates the script for you. For every function it can use, see the script reference.

new_subscriber_alert.pyexample

from clickruntime import on_event, notify

@on_event
def handle(event):
    body = event.json
    if body.get("event_type") != "subscription.created":
        return {"skipped": True}
    sub = body["data"]
    notify.slack(f"New subscriber: {sub['email']} · source {sub.get('utm_source') or 'direct'}", channel="#growth")
    return {"posted": True}

FAQ

Common questions

What does the Slack message contain?

It contains the subscriber's email address and the UTM source or referring channel when beehiiv provides one, plus the time. If you would rather not share addresses in Slack, the message can show only the source and the domain.

How is the webhook set up in beehiiv?

In beehiiv's settings you add a webhook and choose the subscription created event, then paste the ClickRuntime URL that your AI assistant provides. From then on, each new subscription sends an event to ClickRuntime as it happens.

Does it include free and paid subscribers?

The event fires for new subscriptions, and the payload says whether it is free or premium. You can post all of them or only paid subscribers to a separate channel, which is useful if upgrades matter more to you than free signups.

What permissions does it need?

API key. Nothing else in your accounts is used.

Does it need AI?

No. It runs without AI, so it doesn't use your plan's AI allowance.

How many runs does it use?

One run for each event the app sends.

Can I change how it works?

Yes. Describe the change to your AI assistant, for example a different schedule, channel or filter. It updates the automation, tests it and tells you what changed.
