Open, click, and conversion tracking with privacy-aware fallbacks

Opens are not what they used to be. Apple Mail Privacy Protection inflates open counts for everyone using Apple Mail with the proxy on; corporate security gateways pre-fetch links and show false clicks; tracking pixels are routinely blocked. We surface these distortions instead of pretending they don't exist.

Capabilities you don't have to build, monitor, or babysit

Each capability ships on the standard plan. Nothing in this list is an upsell or a separate product line.

01

MPP-aware open accounting

Opens are tagged as 'human', 'machine-prefetched', or 'MPP-proxy' so you can compare apples to apples. Reports default to a 'real opens' view, with the inflated number available if you need it for an executive deck.

02

Click attribution with link hashing

Each link is rewritten with a recipient-scoped token; clicks are deduplicated within a session, attributed to the specific message and step, and chained to downstream pageviews if you've installed the JS snippet.

03

Conversion stitching to your application

When a user clicks an email link and then makes a purchase or completes a goal in your product, we stitch the conversion back to the message that brought them in — even if hours or days passed. Works with any cookie-based or user-ID-based analytics setup.

04

Privacy-respecting defaults

Tracking can be disabled per-recipient, per-template, or per-jurisdiction. Recipients who opt out are excluded from open and click pixels at send time, not filtered after the fact — important for CCPA, CPRA, and emerging US state laws.

Where US customers actually use this

  • Measure ROI on lifecycle campaigns with end-to-end conversion attribution
  • Identify and exclude bot-driven clicks from security gateways
  • Track WhatsApp message reach and reaction emoji as engagement signals
  • Run consent-aware tracking for recipients in CCPA states
  • Feed engagement scores back into the audience-segmentation engine

All tracking data is queryable from the same place you queue messages — there is no separate analytics product and no extra license required for the marketing or product team to look at the results.
