Answer 1

To be able to add system config variables to email templates it is not enough that they are defined in system.xml and added to core_config_data.

You must also make them appear in the list of variables that appear when you click

Insert Variable…

In the email templates:

To do this you have to define a config path in your di.xml like this:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Variable\Model\Source\Variables">
        <arguments>
            <argument name="configPaths" xsi:type="array">
                <item name="custom_finance/general" xsi:type="array">
                    <item name="custom_finance/general/finance_text" xsi:type="string">1</item>
                </item>
            </argument>
        </arguments>
    </type>
</config>

It will then appear in the variable list and you can use it in your email templates:

Good luck!

Answer 2

Please check core_config_data table has store value or not

SELECT * FROM `core_config_data` WHERE `path` LIKE "custom_finance%";

I Hope This Helps You.
