Immediately receive email notifications when a visitor accesses a page on your site. Provides a user\’s basic information to you as soon as they visit the page, such as time of access, user agent, HTTP referrer, anonymised IP Address and approximate location and timezone.

And instead of immediately receiving an email about the visitor the email can be delayed by a day or hour which will send a visit summary.

This plugin includes a built-in copy of ACF, see https://www.advancedcustomfields.com/resources/including-acf-within-a-plugin-or-theme/
