[Plugin: Subscribe2] Using advanced custom fields

Hello,

After reading this usefull post I have one question:

http://ww.wp.xz.cn/support/topic/subscribe2-and-custom-fields

To use the custom fields metadata in subscribe2 plugin you first have to save a draft and publish the post after. Is it possible delay the email sending to have the metadata saved (or save the metadata before sending the mail) ?

Thanks in advance.

Regards.
