Here’s the low-down on how conversion attribution works in Drip:

To convert by visiting a page, a subscriber needs a cookie (either from when they subscribed, or anytime they’ve clicked through from an email sent by Drip).

Conversions can also be recorded manually via automation rules or API events.

Once Drip records the conversion via the Drip JS snippet, Drip looks to see if that conversion links up with a cookied subscriber. If it does, we attribute it to the subscriber’s most recent email delivery.

So if a subscriber had been receiving emails as part of multiple campaigns/broadcasts, credit would go to the one from which they’d received an email most recently. We will attribute a conversion to a delivery even if we don’t have an open or click event for it (since open tracking is not 100% accurate).
