More or less a few arrays to setup, I would suggest tacking onto an observer event (or a core rewrite, in which case you'll find the send function for customer registrations in the mage core customer folder!) to send your custom script out (there's a list of the observers available if you google!):
Declare the sender as an array:
$sender = Array('name' => 'You',
'email' => 'you@domain.com');
The recipient address, just literally needs to be a string, similarly to the mail subject.
$email = 'customer@customer.com';
Set your template id:
$templateId = 40;
And finally declare your custom variables to be sent along to the template:
$vars = Array('nameOfCustomer' => $customerName,
'shippingDetails' => $shipping,
'storeName' => $store_name,
'storeURL' => $store_url,
'orderId' => $orderId);
Followed up with the send function, i tend to just leave the $name as a null var:
$storeId = Mage::app()->getStore()->getId();
$translate = Mage::getSingleton('core/translate');
Mage::getModel('core/email_template')
->setTemplateSubject($mailSubject)
->sendTransactional($templateId, $sender, $email, $name, $vars, $storeId);
Then in your template call the var as literal for example:
{{var storeName}}
It's probably your database entries.
Take a look at core_config_data:
SELECT `value` FROM `core_config_data` WHERE `path` = 'snh/emailsettings/headerfnt';
If it does return something, then it'd be a scope problem then. Check if scope and scope_id checks out (global, website, store level?). Safest way to go is default and 0, respectively.
If it does not return anything, then you need to insert something for this. You obviously probably know now what to insert, right?
