The content of the generated email can be changed in the EME GDPR preferences.
So in fact it is a 2-step procedure:
If the url you give to people contains the parameter eme_email (with value a valid email address), that email will be used to prefill the email field in the resulting form.
2) after the user enters his email and submits the form, he/she gets an email with a link towards the personal data stored.
It accepts the following optional parameter:
show_info_if_logged_inif set to “1” or “true the shortcode will immediately show the form if the person viewing the page is logged in and a linked EME user is found. Defaults to false. Possible values: 0 or false, 1 or true
To allow people to change some of their personal data, you can use the shortcode
Note: if the page that contains this shortcode has a parameter eme_email in it (e.g. email@example.com ), then that email will be used to prefill the email field. This allows you to mail the url to this page (via EME) to a lot of people and have their email already filled in (so less work for the receiver).
