Where a subscriber came from

Jounce records how each person joined your list, so you can tell a signup from an import months later.

The four sources

Source	How they joined
Added manually	You typed them in with Add subscriber › Add manually.
CSV import	They came in with a file through Add from CSV.
Signup form	They filled in one of your forms.
API	Another tool added them through the developer API.

Where it shows

Open the person from the list and look under Details on the right. Source sits below Date added and Consented, and names how they joined. Below the rows, Consent record holds the proof: the form they used, the words they agreed to, and the internet address Jounce saw. See The consent record.

The Activity list on the same page ends with the same fact, as its oldest line: Joined · Signup form, for example.

On the Subscribers page, the filter builder has Signup source. Use it to show everyone who joined one way, such as every CSV import.

When it shows a dash

A dash means Jounce has no record of how that person joined. That happens for people added before Jounce kept the source. On Analytics, the same people are under Not recorded. See Why does Analytics say Not recorded?.
