Track links used in Substack campaigns.

Substack publishers can use a complete URLTracker address as the destination for an ordinary hyperlink in a post or email, then publish that same content on the web. This workflow does not require URLTracker to request access to your Substack account. Create the destination and tracking route in URLTracker, then place the resulting HTTPS address into a supported link field in your campaign editor.

The redirect records permitted request context and forwards the browser to the configured destination. URLTracker can organize time, estimated unique activity, available referrer and campaign labels, device and software patterns, approximate network geography, recognized automation, and supported outcomes. It cannot read an inbox, inspect private message content, or verify a recipient’s identity.

Create separate routes when you need to compare primary calls to action, editorial links, sponsor sections, welcome emails, web-post links. If two placements will always share a destination and never support different decisions, one route may keep reporting simpler. Use a clear internal name containing the programme, message, placement, and launch period.

Apply a documented UTM pattern such as the sending programme for utm_source, email for utm_medium, the initiative for utm_campaign, and the specific button or section for utm_content. Keep subscriber names, email addresses, list membership, and private CRM attributes out of public URLs.

• Use utm_medium=email consistently
• Give decision-worthy placements distinct routes
• Keep recipient and CRM data out of URLs
• Record the owner, destination, and launch date

Substack, mailbox providers, social previews, and security services may process a published link or request the web-post version independently of a subscriber click. This can create a redirect chain or automated request that differs from a direct browser test. Mailbox providers, corporate gateways, and anti-phishing products can also request the URL before or after delivery.

URLTracker separates recognized automation where possible, but no classifier is perfect. A click total is not proof that every event came from a reader, and email-open pixels are affected by image blocking, caching, and proxying. Use campaign context, timing, devices, repeated patterns, and downstream outcomes together.

Use a private or small-audience proof, check both the delivered email and web post, and confirm that subscriber and sponsor links remain distinguishable. Confirm the visible call to action matches the destination, the route uses HTTPS, required UTMs survive every redirect, and mobile visitors reach a fast page. Do not wait until a full-list send to discover that an editor, template, or security layer changed the journey.

After launch, compare eligible clicks, unique estimates, placement, device context, conversions, and value with a consistent date range. Substack and URLTracker may report different totals because their rewrite layers, bot rules, identities, retention, and time zones differ. Reconcile important outcomes with the authoritative business system rather than forcing unlike numbers to match.

Send only expected communications to an appropriately permissioned audience, identify the sender, and preserve required preference and unsubscribe journeys. Avoid misleading anchor text or a branded route that disguises the true purpose of the destination. A short link should improve management and attribution, not reduce accountability.

Use the minimum data necessary, restrict event exports, establish retention, and document how campaign analytics are used. Test domain reputation and delivery with the real sending configuration. When both Substack and URLTracker add redirect measurement, assess whether the extra layer is appropriate for the campaign and audience.
