Hi,
how does that make sense?
Sorry this depends from Acymailing, of course, if you have something like info:receiver, so, this behavior is normal and works as expected.
can I change it to info:user?
You can try with info:sender, but keep in mind that the sender need to be a user, if email are sent by system email address then also this way will not works.
why would the admin need to see their own info in that email??
Acymailing Tag system is designed for newsletters and not for Joomla notifications
also, the name and email it gave me were NOT the ADMIN name and email, they were the USER info.
tags like {Param1} {Param2} ... not come from Acymailing tag system
