How to add php codes to template

Hi,

I need to add a code to the email template, where can I add it? The instruction says:

“It’s necessary to add do_action( “alg_wc_ev_activation_email_content_placeholder”, $email->object ) to the “Customer new account” email template.”

Seems that in your email template editor, there’s no component to add the code.

I added a comment on Codecaeyon. When I tried to delete it, I cannot find that comment any longer.

Thank you.

Vincent
