# Automation Flow - Change/Delete lead information

In this example, you imported leads with incorrect common information. To avoid deleting/modifying this information manually, follow this step-by-step:

1 - Create a segment with a filter. To do this, search for Segment in the Menu

2 - In the Filters tab, click +New Filter, and add the option:\
"The lead field value is", choose which field contains the information you want to delete/replace, then select the option "Equal to" and type exactly as it appears in the indicated field.&#x20;

In the example below, the leads received the data 55 and +55 in the mobile field

3 - Now let's configure the <mark style="color:red;">**Automation Flow**</mark>. In the menu, search for Automation Flow, click +New and type a name

4 - Open the builder and add the action block "Modify lead data", indicate the field that will be modified, and type what will be changed/deleted.&#x20;

In our example, we want to leave this field with the data deleted, so we leave the field empty.

Click apply, and save the flow.
