Hello from Brazil,
I am using trello to automatically send e-mails to my peers with their job responsibilities. They can not have access to my Trello due to some company restrictions. We also aren't allowed to create a shared space. To make my life easier, I've created an automation button to do almost everything to me, and it was working perfectly until yesterday.
It is supposed to work like this:
I set my card description manually with the e-mail I want to receive the notification, and the automation sends the e-mail. Unfortunately, the following message appears on my screen after I hit the button: The email address xxxx@outlook.com is invalid.
The automation is:

Send an e-mail notification to: {carddescription}
With subject: XXXX
And message: XXX
No mistakes related to miss typo are being made.
Please, may someone help me?
