# Manage your customers across events

> See every vendor and attendee from all your events in one place, import contacts, organize them into lists, export to CSV, and email them.

**Customers** collects everyone who has bought from you or applied to your events, across every event you host. Use it to see who's new and who keeps coming back, import your existing contacts, sort people into lists, export your data, and send blasts that span more than one event.

## Open Customers

In your host dashboard sidebar, select **Customers**. The page has four tabs:

| Tab | What it shows |
| - | - |
| **Vendors** | Everyone who has applied for a table at any of your events |
| **Attendees** | Everyone who has bought a ticket to any of your events |
| **Imported** | Contacts you uploaded from a CSV |
| **Blast History** | Blasts you sent from Customers |

On the **Vendors** and **Attendees** tabs, filter by **New** or **Returning**, by event, by list, and for vendors by tag. Use **Search** to find someone by name or email. Click a person to open their details, including their history at each of your events.

## Import contacts

Bring in an email list from another tool so you can include those contacts in blasts.

**1. Open the importer**

On the **Imported** tab, open **Import Contacts**.

**2. Upload your CSV**

Click **Click to upload a CSV file** and choose your file.

**3. Map your columns**

Match your file's columns to Treasure's fields. **Email** is required. **First Name**, **Last Name**, **Full Name**, **Business Name**, and **Phone** are optional. Rows without an email are skipped.

**4. Import**

Optionally pick a list under **Assign to list**, then click **Import Contacts**.

Each upload is kept as its own import batch, so you can filter the **Imported** tab by import or message a single batch later.

## Organize customers into lists

Lists are your own labels for groups of customers, such as VIPs or follow-ups.

1. Click **Lists** to open **Manage Lists**.
2. Enter a **List name**, choose a **Color**, and create the list.
3. To add people, select them in the table and use **Assign to list**.

You can rename, recolor, or delete a list from **Manage Lists** at any time.

## Email your customers

Select people in any tab and click **Add to Message** to add them to a blast. You can also open the composer from the **New Message Blast** bar at the bottom of the page.

From Customers, **Add recipients** offers groups that span all your events, in addition to the groups on an event's blast page:

* **All imported contacts**, or a single batch under **Imported batches**
* Any of your **Customer lists**
* **Returning vendors**, **New vendors**, **Returning attendees**, and **New attendees**
* **Vendor statuses by event**: accepted, pending, waitlisted, rejected, paid, or unpaid vendors, across **All hosted events** or for one event

See [Email blasts](https://docs.ontreasure.com/features/email-sms-blasts.md) for composing, scheduling, and tracking blasts.

## Export to CSV

**1. Open the export**

Click **Export** to open **Export customers**.

**2. Choose what to include**

Under **Include customer groups**, check **Vendors**, **Attendees**, **Imported**, or any combination. You can narrow the export to a list, then pick the columns you want. Use **Select all** to include every column.

**3. Download**

Click **Download CSV**.

Available columns include name, business name, email, and phone for everyone. Vendor columns include how many of your events they applied to and paid for, and their upcoming events. Attendee columns include tickets purchased and scanned, last purchase date, and events attended. Imported columns include the import date and batch.
