# How to bulk delete customers by email list

There's no direct "delete by email list" operation, but you can combine an action import with a filter-based deletion to remove customers when all you have is their email addresses.

<Note>
  Deleting by a list of Maestra IDs is straightforward. Deleting by email takes a few extra steps, outlined below.

## High-level approach

1. Create a **marker action** that you'll assign to every customer you want to delete.
2. Import that action from a file containing the email list.
3. Build a filter that matches customers who received the marker action.
4. Delete the matched customers.

## Step-by-step

### 1. Make sure you have a marker action template

Confirm that your project has a marker action template intended for deletion. If it doesn't, create one first.

### 2. Assign the action to your customers

Prepare a CSV file with a single column named `Email` listing the addresses to delete.

Import the file using the **Customer action import with identification by email** operation. See [How to bulk import actions from a file](/import-data/actions/how-to-bulk-import-actions-from-a-file) for the full workflow.

### 3. Build a filter

Create a customer filter that matches everyone who received your marker action (for example, "Marker for deletion").

### 4. Delete the matched customers

Run a delete task on the filtered set. See [How to bulk delete customers by filter](/import-data/customers/how-to-bulk-delete-customers) for the procedure.

<Warning>
  Customer deletion is permanent — all customer data and actions are removed.
