I have a WordPress+WooComerce site and would like to integrate a newsletter sign-up checkbox in the checkout and customer registration page, but without linking to a service provider, because we still have to decide the right service and other details regarding our newsletter strategy. In other words, at this stage, we only want to collect contacts that have given explicit authorization to receive a newsletter. Unfortunately all plugins seem to need an integration with some newsletter service provider like Mailchimp or Sendinblue and we are still deciding which one to use.
Does anybody know a simple way to add the above mentioned checkbox so that we can record the consent given by the customer together with his details and use this to send him/her newsletters in the (near) future?
Tanks in advance.
