Customize opt-in Activation Link

Question

Is there any way to customize opt in approval link? Tricks like this won't work: {% ActivationLink %}specialID={% %}
I would like to pass some additional parameters to Activation page. I am using Kentico 9.

Answer 1

Have you tried with this macro ?

{% ActivationUrl %}

This macro is present in the email, but it isn't visible in the editor in admin UI
