Sendible also gives you tools to keep track of how your company, or its products or services, are being discussed on Twitter or other social networks (using a sentiment analysis engine to find positive and negative mentions), and prioritizes which mentions or posts you should respond to. You can view your activity within a My Reports tab on Sendible, or you can configure Sendible to send an email at regular intervals summing up social network activity related to your brand or company. You can also manage Sendible accounts with an iPhone app.
Sendible also lets you automatically follow other Twitter accounts with similar interests, and it can automatically send a welcome message to any Twitter user who follows your account. One thing that would make Sendible a better tool is to include a feature like those in TweetAdder and MarketMeSuite that also automatically unfollows unproductive accounts.
Sendible also lets you view Twitter lists or create new lists, to limit the number of Twitter accounts populating a stream.
Sendible has a confusing array of pricing plans ranging from $9.99 per month for the Solo plan (which lets you send up to 400 messages at a time with a maximum of 15 social network accounts and 500 contacts) up to $99.99 per month for the Corporate plan (which lets you send up to 32,000 messages at a time with a maximum of 400 social networks and 32,000 contacts). The different plans offer varying caps on the number of contacts that a given message can be sent to, the number of social networks that can be managed and maintained from Sendible, the maximum number of contacts, and so on.

This tool is more focused on analytics than the others covered here. Tap11 lets you monitor the vast Twitterverse to listen to what is being said about your company, track how much exposure your tweets get, discover which Twitter accounts wield influence within your industry and receive email alerts when news relevant to your products or services breaks.
I really like the analytics tools and reporting in Tap11. It is valuable from a social media marketing perspective to be able to track and monitor the audience for your tweets. You can send the same message out with different wording or at different times of the day, and monitor to see which tweets are getting the most exposure. Information like this can help you optimize your social media marketing efforts.
Like many of the other tools reviewed here, Tap11 lets you work with Twitter more efficiently by letting you schedule outbound tweets. However, Tap11 is not as robust when it comes to features for managing -- adding or unfollowing -- Twitter followers.
One advantage Tap11 does have over most competing products is mobile integration. Sendible has its iPhone app, but Tap11 has apps for iPhone and BlackBerry.
As this was being written, Tap11 was still a pre-release trial; pricing had not yet been set.
Price: $55/1 profile; $74/5 profiles; $110/10 profiles; $188/unlimited profiles
