Tickr

Ensure Your Newsletter Content Delivery Is Flawless

For creators using platforms like Substack or ConvertKit, reliable API performance is crucial for subscriber engagement and content access.

The problem

Many newsletter creators rely on integrations or custom scripts to enrich subscriber data, trigger drip campaigns, or deliver exclusive content after payment. When the APIs powering these automations (e.g., ConvertKit's subscriber management, Substack's payment webhooks) experience downtime, welcome sequences fail, premium content remains locked, or audience segmentation breaks. This directly impacts subscriber experience, perceived value, and potentially revenue, leading to frustrated readers.

Indie creators often lack sophisticated monitoring tools, only discovering issues when subscribers complain about missing emails or inaccessible content. Manually checking API status pages is reactive and time-consuming, diverting focus from content creation. An outage during a critical launch or content drop can mean lost sign-ups, reduced engagement, and a damaged reputation, making proactive detection essential for maintaining reader trust and platform health.

How Tickr solves it

1
Instantly detect when your newsletter platform's API endpoint is unreachable or returning errors.
2
Receive immediate alerts via email or Telegram when subscriber automations are at risk.
3
Proactively address issues impacting welcome sequences or premium content access before readers notice.

Concrete example

curl -X GET \
  "https://api.convertkit.com/v3/subscribers?api_secret=YOUR_SECRET" \
  -H "accept: application/json" \
  -v \
\
< HTTP/1.1 200 OK\n< Content-Type: application/json\n< Date: Mon, 1 Jan 2024 12:00:00 GMT\n< Server: Cloudflare\n< Content-Length: 78\n< Connection: keep-alive\n{\n  "subscribers": [\n    {"id": 1, "email": "test@example.com", "status": "active"}\n  ]\n}

Frequently asked questions

Can I monitor my custom integration with Substack?
Yes, simply add the URL of your endpoint that interacts with Substack's API. Tickr will probe it to ensure it's always responsive and returning the expected status code.
What if the API is slow but not completely down?
Tickr monitors for response times too. If your endpoint consistently exceeds a defined threshold, you'll be alerted, indicating potential performance bottlenecks affecting content delivery.
Is this only for public APIs?
Tickr can monitor any HTTP endpoint you provide, whether it's a public API from ConvertKit or a custom backend service you've built to power your newsletter.
