Schedule tweets and keep your Twitter stream ticking over with new tweets even when you're not in front of your computer. Publish tweets when your international followers are online and you're asleep.

Set up alerts and track keywords in the public Twitter stream. We will monitor the Twitter tweet stream and periodically email you a digest of the tweets that contain those keywords. You can also use this to track your @replies.

Save draft tweets, frequently used text snippets and URLs and reuse them in your scheduled tweets. Save tons of time by avoiding repetitive typing.

Send a nice non-promotional DM to new followers that focus on them and your future interaction with them, or simply to thank them for choosing to follow you.

Add your bit.ly URL shortening account details to your TweetLater profile, and we will shorten your links with it so that you can track the clicks on all your links.

Automatically follow people who follow you and save a ton of time while your Friends list builds itself.

Automatically unfollow someone when they unfollow you if that is how you prefer to manage your Friends list.

Even though you've selected to auto follow new followers, we will interrupt the process for 72 hours and give you an opportunity to manually review new followers and decide if you want to follow, ignore, or block each new follower.

You will probably agree that it's a bit of a pain to manually delete DMs from your Inbox, especially since they accumulate so quickly. You can run a purge on your Inbox to delete everything, or DMs older than 7 days, or DMs older than 30 days.

Grab your own personal 140-character tweet scheduling engine and RSS feed. You can schedule and publish tweets that don't go to Twitter, they go to your personal tweet stream, which is available in RSS, XML and Javascript formats.

Add and manage as many Twitter accounts as you want. We don't charge you a dime.

Fire up your Direct Message Manager where you easily manage the direct messages of all your Twitter accounts from one central and integrated console.

Tell the system who and what to treat as SPAM, and we will make sure you never even see those DMs in your Direct Message Manager. We also delete those SPAM DMs from your Twitter DM inbox.

Set up words and phrases that you consider as SPAM and we will automatically get rid of any DM that contains any of those words.

Tell the system to automatically treat as SPAM any Twitter account that has already been flagged as SPAM by any of your fellow TweetLater Professional users.

Wear your coolest shades when you climb into your TweetCOCKPIT where you easily manage all your Twitter accounts from one central and integrated console.

On one page in TweetCOCKPIT, see your normal timelines (integrated) and pull in additional tweets that contain certain keywords regardless of whether you follow the tweeter or not. Find new folks to follow or new friends and business contacts at one easy glance, and follow them or tweet to them.

Even though you follow thousands, configure your timeline in TweetCOCKPIT to display tweets only from the handful of people you're more interested in hearing from.

Want to follow, unfollow, or block a person on more than one Twitter account with one click? No problem. Tweet and retweet something on more than one Twitter account with one click? No problem. Favorite a tweet on more than one account with one click? No problem.

Easily forward a DM to someone else without having to copy and paste, and go from page to page to perform this action. One simple click and you're done.

Whether you follow a person or not, mute people in TweetCOCKPIT if they annoy you. You won't see their tweets. Unmute them whenever you feel like it.

When you've read a tweet, hide it and it will not show up again and clutter your view.

Include or exclude Twitter accounts, or sections of Twitter accounts (timeline, favorites, DMs, search results). Color-code accounts to make them easy to identify. Specify the number of tweets you want to see for each section of each account.

If you have an assistant, you can delegate the management of your Twitter account to that person while keeping the master Twitter account entry in your TweetLater profile and keeping your Twitter password secret. This is also a great feature for corporations who want to enable several employees to manage a Twitter account, without having to know the password. For example, a media company could delegate the Twitter account of a TV station to the station manager, the regional manager, and the VP's personal assistant. The VP can easily schedule a tweet on all TV station Twitter accounts in one single action, the regional manager on all TV stations in her region, and the station manager only on his station's Twitter account.

How often do you tweet an @reply or send a DM when the recipient is either asleep, or usually not on Twitter? Now you can schedule @replies and DMs to be sent when you know the person is usually on Twitter.

Schedule tweets that will be published every X number of hours, days, or weeks. To avoid having the tweet say exactly the same thing every time it is published, provide alternate tweet text options (multi-level spinnable tweet text) from which the final tweet text is compiled every time a recur is published.

While a recurring tweet is going through its cycles of publishing, pause the publishing if you don't want it to unexpectedly appear in your timeline while you're doing a demonstration or presentation, or don't want a longer term recurring campaign for a product to go out while you're doing a short-term promotion of another product.

If you have many tweets to schedule, prepare them offline, put them in a simple text file, and upload them in bulk. Save time by not having to enter and schedule them by hand in the system.
