saving emails into WP users database

Hello,

I have Mailpoet installed on my WP site. I don’t have a Mailpoet form set up on this site yet to gather emails.

I have installed a plugin called Site Reviews, which allows visitors to review my product via a form on my site.

The Site Reviews users will enter a name and email address before entering a review – although that plugin does not add the user information to the WP users list. The plugin author said I needed to use a hook for this, which they don’t provide. They provide a code hook for actions after a user leaves a review, but not the specific code to perform the function I’m describing.

I want to save each name/email from the Site Reviews form into my WP users list, but the plugin author suggests that since I’m using Mailpoet, perhaps there’s a way to do this via Mailpoet.

If I only get a few reviews, I could enter them by hand. However, I would prefer instead to automate this.

Any tips or suggestions are appreciated.
