# Block

The Block Person operation allows you to change a contact's block status. A blocked person typically stops receiving communications and may be removed from certain automations, helping keep your contact base clean and respecting privacy requests.

This action can be used to either block or unblock a person, simply by changing the parameter value.

#### How to Configure

1. In Hablla Studio, add the "People" block to your automation flow.
2. In the "Operation" field, select the "Block" option.
3. In the "Person ID" field (`personId`), enter the unique identifier of the person whose block status you want to change.
4. Set the "Block" field to `true` to block or `false` to unblock.

### 🚀 Example Use Case

Goal: Automatically block a contact in Hablla when an email sent to them results in a "hard bounce" (permanent delivery failure).

1. Create a flow that uses a trigger from your email service (via Webhook) that fires when a "hard bounce" occurs.
2. The trigger will receive the recipient's email that failed.
3. Use the "Find Person by Email" operation to find the ID of the person corresponding to that email in Hablla.
4. Add the "People" block with the "Block" operation.
5. In the "Person ID" field, enter the ID variable found in the previous step (`{{steps.2.result.id}}`).
6. In the "Block" field, set the value to `true`.

With this automation, your contact base stays clean, avoiding future sends to invalid email addresses and improving your sending domain's reputation.
