Tented ships with a rich set of standard fields, and you can extend them with up to **200 custom fields** of your own. Manage them all in one place: **Workspace Settings > People > Manage Fields** (or **Settings > People**). From here you can also **Export** your full field schema.

The subscription fields (like **Unsubscribed**) are managed by Tented's email pipeline — they update automatically when contacts unsubscribe, and marketing sends respect them without any work on your part. ## Custom fields Anything your business cares about that isn't standard — plan tier, account owner, renewal date — becomes a custom field. Custom fields show up on contact profiles, as mapping targets during [CSV import](/people/importing-contacts), and in [audience rules](/people/working-with-lists) for filters and dynamic lists. To add one, click **Add field**: 1. Give it a **display name** — Tented auto-generates the API name (e.g., "Plan Tier" → `plan_tier`). 2. Pick a **type**: String, Number, Boolean, or Date. 3. Decide if it's **editable in the Tented UI** — turn this off for fields that should only be written by imports or the API, and they'll show as read-only on contact profiles. A screenshot of the Add custom field dialog with a display name of Plan Tier, an auto-generated API name, and the type dropdown showing String, Number, Boolean, and Date. Your custom fields appear at the top of the fields page, where you can rename them, toggle editability, or archive ones you no longer use.

You can also create custom fields on the fly during a [CSV import](/people/importing-contacts) — map an unmatched column to a new field without leaving the import flow. ## What's next? Put your fields to work with a bulk import.
