Jira Service Desk Cloud welcome email

[Almut Jenk]

Is there documentation about what happens when a customer never completes the registration via the welcome email, and keeps interacting via email notifications, and then eventually they do not open an attachment in one of the notifications, because they are confused by a login prompt? How can we guide such customers more successfully? I just couldn't find the time with so many requests to sit down, create some customer dummy account, and do a full documentation of what the customer experience will be like in that scenario but it does come up pretty often...
