1) Is it somehow possible to preview the e-mails in the e-mail editor before the e-mail will actually be sent?

Currently we do not have allow admin to preview the email layout from the email template section.

May i know which kind of email you would like to see?

2) What is the easiest way to edit all the e-mails? Just translate the language strings, or text inside the PHP file?

It actually depend on what you need to modify the email content layout, if you just want to modify the sentences, I would suggest you to override that language constant string from your backend, so you do not need to modify it from the PHP code.

Hi Arlex,

Thanx for your quick reply!

1) Oke no preview mode in the admin, i understand But how do i test/check the e-mails that are send that i have aplied via the e-mail template editor? Is the only option to just sent the email to an test account and see for myself in live mode? It does not have to be a problem but If so, can we manipulate to send e-mails even without doing the actual action that is needed on the front-end (For example, the 'we've missed you' e-mail) to a specific account?
So that i don't have to wait 30 days or so to receive this e-mail?

2) thnx! i will trie for myself but the most logically wil be the language strings.

It seems like that is no easier way to preview this unless modify the code.

But you can share with us what you have done that email template (For example, the 'we've missed you' e-mail), so we can try this in locally and show you the email preview content.
