Changer le "Nom" par le "code postal"

Hi,
if I understand well, you would like to replace the standard Name field with a code postal field.
You can do it in 2 steps:

• disable the Name field, in dashboard: Newsletters > Settings > tag General > Hide Name input in form
• add the new code postal field via php: there is a how to in this page https://www.eventualo.net/blog/easymail-newsletter-for-developers/#tutorial-customfields

I hope it helps.
