+Label modifier for select and boolean fields
+--------------------------------------------
+
+For select and boolean field types, you can display the human-readable label instead of the stored value by using the ``|label`` modifier:
+
+.. code-block:: php
+
+   {contactfield=select_alias|label}
+   {contactfield=bool_alias|label}
+
+This is particularly useful when these fields contain technical values, but you want to show user-friendly labels in your Emails. For instance:
+
+* A country selection field storing ``us`` can display ``United States``
+* A boolean field storing ``1`` can display ``Yes``
+
+The modifier also works with Company fields:

+Label modifier for select and boolean fields
+============================================
+
+For select and boolean type fields, you can use the ``|label`` modifier to display the human-readable label instead of the stored value. It's beneficial when your select fields store values like codes or IDs, but you want to display friendly labels to your Contacts.
+
+**Syntax:**
+
+.. code-block:: text
+
+   {contactfield=field_alias|label}
+
+**Examples:**
+
+* For a select field with alias ``country_select`` that has options, such as ``us`` for ``United States`` or ``uk`` for ``United Kingdom``:
+
+   * ``{contactfield=country_select}`` displays the value ``us``
+   * ``{contactfield=country_select|label}`` displays the label ``United States``
+
+* For a boolean field with alias ``is_subscriber``:
+
+   * ``{contactfield=is_subscriber}`` displays the value ``1`` or ``0``
+   * ``{contactfield=is_subscriber|label}`` displays the label ``Yes`` or ``No``
+
+* For both Contact fields and Company fields:
+
+   * ``{contactfield=company_type|label}`` displays the label of a Company select field
+   * ``{contactfield=company_active|label}`` displays the label of a Company boolean field
+
+.. note::
+
+   The ``|label`` modifier only works with select and boolean field types. For other field types, it displays the regular value.
