Email variable for Butler automation

[Yeshodhara Baskaran]

I am currently trying to do the below,

Instead of entering an email address, can I use another variable which takes the email ID of the person mentioned? 

Like {mentionedusername.email} ? Is there a variable like that which I can use?

HI @Yeshodhara Baskaran ! I guess you would need some way to map the username to the email address so Trello knows what user correlates to what address. One idea could be to create a sort of "directory" of users. So the idea would be to create cards titled with each member's username. Then, in the description or a custom field, enter the email address for that person. 

Your butler command would then incorporate looking up the relative card and use either the description or custom field variable to pull in the correct email address.

E.g. when someone is mentioned in a checklist on a card, lookup a card titled {mentionedusername}, send email notification to {{%Email Address}}.....

These "directory" cards could exist within the same board, or a separate board.

I haven't tested it out, but I'm guessing it should work!
