Bulk email integration (e.g. MailChimp, SendFox)

This would allow us to communication with our customers when needed (e.g. sales, promotions, general updates).

Bulk email functionality to communicate with customers would be helpful - without having to export my contacts in CSV out of Zoey, then import them into a bulk email system. Also, unsubscribes would need to be manually entered back into Zoey. This is a lot of manual work, hence the suggestion for native integration with a bulk email provider.
