Would be great to have the ability to create custom post types like email marketing, direct mail campaign, etc - that can be tracked along side of social media calendar to give agencies a look at all the marketing being done for their clients. Even if sendible can't connect to email providers for scheduling, like mailchimp, drip, aweber, etc - would be good to be able to show clients the emails that would be going out for them in a text area on sendible right next to the social campaigns queued upfor them.
