Hi! Trello is using our user's first and last names when it generates invite emails. This is a bad practice as it gets caught in phishing filters:
From: Tom Jones <invitation-do-not-reply@trello.com>
It would be better if Trello did not impersonate users and instead sent emails from "Trello", e.g:
From: Trello <invitation-do-not-reply@trello.com>
