Preview Subscription Confirmation Email

Audience > Settings > Audience settings > Edit email

1. Please enable preview option (similar to the Campaign) so that we can see how the subscription confirmation email looks like.
2. Please consider an option to add a "send test email" so that we can further test how the email looks like on different devices.
3. Please allow the use of Templates (rather than having to design a standalone email from scratch and cannot be used anywhere else).
