Hi,
Ok, I think it's indeed clear now.
In your PDF, the first email is an email sent by HikaShop. And it looks like the "user account admin notification" email, which is sent to the admin in step 2.
The second email is the admin activation email, which is sent by Joomla on step 4, not HikaShop.
So you can't customize this email via the System>Emails menu of HikaShop.
Instead, Joomla has an interface to customize its emails:
magazine.joomla.org/all-issues/february-...tml-email-templating
Someone else talks about doing the same thing as you want here:
forum.joomla.org/viewtopic.php?f=811&p=3694490
But no one answered him as to how to do it.
Looking a bit in the code of the mail templating component of Joomla, it has an event called onMailBeforeTagsRendering($template_id, &$mail) which can be implemented in a plugin of the group "system". The $template_id contains the id of the email template and $mail is an object with the data of the email. In it, you can add extra tags to the array
Then, you can also implement the event onMailBeforeRendering($template_id, &$tags) in that same plugin. The $template_id is still the id of the email template, and $tags is an array where the keys are the names of the tags and the values are the values to replace.
So it's not possible to do if you're not a developer. If you're a developer, with a bit of tinkering, you'll be able to do it.
