Timely supports unlimited Twitter accounts and offers a browser bookmarklet, allowing you to queue tweets without having to visit the site. You can select the number of tweets Timely sends out each day so that you’re not too noisy, and weekend tweets can be switched on or off depending on your preference
Here’s how it works:
You sign up and input the tweets that you want to publish.
Timely will use data from your previous 199 tweets to choose the best time to publish in order to get the best response.
If you want your tweet out fast, you can ask it to post at the best time within the next 30 minutes, or otherwise you can let Timely choose the optimal point in the future for it to go out.
