Uniform: Get _from email in action calling snippet

i want to create a newsletter double opt in.

but i can not get the users email within the snippet. _from is private and blocked in the action. is there any way without changing the action?

maybe @mzur can help?

it is possible already. the quoted code is called when there is no snippet. silly me. :blush:
