The bells and whistles rise to what you would normally expect from an enterprise solution. Things such as an approval workflow (as basic as it is) are available on lower tiered plans, the reports feature is robust and highly customizable with GA Analytics integration available as well. The publishing system is straightforward and easy to use, providing the ability to save drafts that are easy to navigate back to (unlike Agorapulse, which makes this process astoundingly tedious). I appreciate the tabs being in a vertical sidebar similar to Sprout Social, which lends to making it easy to click around. The content discovery works well and allows custom RSS feed additions so I never have to go back and forth between that and Feedly to find content to curate. There's also a universal bookmarklet and Canva integration too, while monitoring is enhanced by integrating Google Alerts and offering email notifications when there's activity on a handful of review sites (with more available if you sign up for ReviewPush). The mobile app, at least for the iPhone is clean looking and obviously well supported, unlike MANY SMM sites that either don't have mobile apps or have one where it seemed to be treated as an afterthought. It was about as well rounded an SMM as I've been able to find.
45 minute sync time (on the Small Plan at least) seems excessively long (especially compared to Agorapulse) if you want to quickly engage and get back to comments made on social channels. Inexplicably, there's no stream for reviews made on Facebook Pages, no Pinterest support (although they appear to be working on adding this back in). There's no way to control email notifications at all for task reminders and other system notifications, which is also strange. Tasks or approvals requests cannot be completed in bulk fashion (so if you submit a LOT of content a week that needs to be approved, the approver will get an email notification for every single content you submit. E.g. if you submit 10 posts for review on a Monday, the approver will get 10 email notifications. Not very efficient. I wish there were a way to set up a calendar of say, 30 scheduled posts in a week, and then submit it all so that my manager/approver only gets ONE email alerting him to content he needs to review. The only workaround I've seen is to upload content via a bulk upload using a spreadsheet (which I hate, but at least there's that option). RSS feed to publish posts as well is also available as well. Content also doesn't have previews, so you won't be able to see how it will look exactly on each channel you want to publish on (however Sendible seems to be working on this too.)
The connection profiles are really bizarre as well. Rather than a single connection for each social profile, in order to integrate all of a single Twitter handle for example, you have to connect at least SIX streams. It makes things incredibly tedious when you have a lot of social channels to manage. Things such as customizing a dashboard for a manager/supervisor who only needs to see content waiting for approval, bit.ly and media library integration are locked behind their far more expensive plans. The dashboard is less customizable than I would have liked, with no option to change settings affecting things such as Trending Topics. The YouTube stream is also very basic, unlike Agorapulse, activity there will only show up in your Priority Inbox, whereas on Agorapulse you can see all comment and other activity in a stream similar to Twitter and Facebook.
To paraphrase a Churchill saying, Sendible is the worst SMM solution... except for all the others. I've tried many platforms, and short of an enterprise solution, Sendible was the only one that was able to cover as much ground as I needed covered without fragmenting management of my company's social profiles across having to use a variety of services.
Consolidating as much of social media management (from publishing to monitoring to reporting/analytics) to under one umbrella as possible.
