Order email notification - full details

Yes. The email notification from our forum

You can edit both the order creation notification email and the order admin notification email via the menu System->Emails.

Some copy/paste from one to the other should do the job.

If you have delays with your email sending process, you should contact your email server provider (in most cases it's your hosting company). HikaShop send the email via the joomla email library to your email server in less than a second. Then, your email server has to process it and send it to the receiving email server. So if you have delays, it's likely that it happens between the email sending server and the email receiving server.

Both emails are sent at the same time by HikaShop.

As I alredy said, there is nothing we can do if it gets slow as the problem is not in HikaShop.

Hi,

HikaShop sends the email to the email server of your server/hosting company the second an order is confirmed. If you have a delay, it cannot possibly come from HikaShop. Either your payment gateway doesn't send the payment notification to your server immediately and the orders are only confirmed 45 minutes after the payment (which I doubt), or your email server is not sending the email immediately, or the receiving email server is not processing it immediately.
If you don't have that delay with other emails in Joomla, then the question is different:
What is the difference between the emails sent by HikaShop and the emails sent by Joomla ?
And there are many things which could play a role in the email servers not directly processing the emails.
For example, if you have the PDF invoice plugin enabled and that it attaches a PDF of the invoice to the emails, that could explain why the email server is not processing it directly.
If could be that the other emails you tried are sent in text whereas the emails in HikaShop are sent in HTML. Go in the menu System>Emails, edit the order status notification and turn off the "HTML" setting there so that only the text version is sent and then do a test. If the email is then sent immediately, then you know that it's the issue. Of course, you'll want to keep the emails in HTML or they won't display nicely, so you'll want to check with your system administrator/hosting company what can be done.
If you come from any other setting in the Emails section of the HikaShop configuration (embed images, multiple part, add names, etc) which are all things that the Joomla emails do not do/handle.

So either you do a lot of testing to understand what is slowing down the sending of the emails by the email server, or you contact your hosting company/system administrator to check on with them what's going on, or you use another email server (many services exist for that).

No, I didn't say that it makes the email slower.
I only said that it could explain why the email server is not processing it directly.
It doesn't mean that this is the cause.
And normally, it doesn't slow the sending of the emails.
But some email servers have security measures in place to check attachments for spam and these can delay the sending.
To make that fast is a matter of how the email server is configured and how much load it has to handle.
That's not something we can do anything about, and probably you too. In such case, the option would be to use another email sending service, or not sending the attachments in emails (there is a setting for that).

But this is only an example of potential issue. It doesn't mean that it is the problem.
Again, the only ones who can help you with such issue is your system administrator or your hosting company support.
We can only point out some possible causes.
