The templates and the drag and drop interface.

multiple brand emails, I love this, it's a game changer!!

Inbox is a game-changer in comparison to old rivals Mailchimp etc. The interface is more user-friendly, and analytics are in more detail. It is the best software if we compare it with others in terms of price, utility, and purpose. Most of the leading software of this category are changing customers either on several contacts lists or the number of e-mails sent. Inbox is the only software that has no such limits at a fixed price.
