Design WordPress "System" Mails
Add a way to design all WP system emails in MailPoet - such as "Forgot Password", or "New User", etc.
Integration with Uncanny Automator
Uncanny Automator do automation from inside WordPress and can integrate mainly with plugins installed and do a very useful automation processes. It will be very good to integrate with it directly to do all sort of automations. I know you Planned an "Automations" feature but kindly consider a native integrations with "Uncanny Automator", also consider "WP Fusion". Both of them do automation from within WordPress CP but "WP Fusion" tend to lean towards "Marketing Automation" like CRMs and such. Thanks

Deleting a WP user should not result in deleting a MailPoet subscriber
I think it would be better (more intuitive behavior) if deleting a WP user would only result in deleting him/her from MailPoet's WordPress Users list. As it is now, the user is deleted as a subscriber and therefore removed from all other lists (s)he subscribed on, which lists may have nothing to do with being a WP user.
Add the ability to initiate email messages and add/remove contacts from lists based on subscriber actions.
Automated email newsletters
It's great that we can automate welcome emails, it would be even better if we could select multiple lists to send one type of welcome email to. At the moment we have to set up a new welcome email for each list as it only lets you choose one option. Many of them have the exact same welcome letter and only a few are customised.
Advanced Ads - Blocks to Menu
Add Advanced Ads blocks to menu option to drag and drop ads into newsletter, I love the shortcode, but it would be nice not to have to remember the id for each one.
