I'm getting this error, how do I fix it?

Trying to run a button and I didn't block any emails from trello. Brand new google email and I'm still getting the error, "The email was not sent because the recipient reported a previous email as spam or abuse."

I was able to fix this issue by changing the email slightly. I entered my email correctly, but butler seems to have blocked it somewhere. Instead of user@gmail.com, I used user+trello@gmail.com. If someone doesn’t use gmail, then idk how to fix it. Please note that the email used was a g-suite email and didn’t use conventional @Gmail.com. There is a possibility that butler blocks gsuite emails by default, but I doubt it as the amendment fixed the issue
