The Share on Twitter button will allow yout o post a marketing piece directly to your Twitter. You can find this button on the Distribute step of creating a marketing piece. Click Share on Twitter.
One quick note at this step: rezora will automatically generate a link for you to copy and paste elsewhere (i.e. Facebook, your blog). This link is also used for the Twitter post. If you click Disable Link, then anywhere you've published the piece, including Twitter, will lead to a page that will say, "This marketing piece is not publicly viewable". So, do not disable the link if you wish for your tweets/posts to continue to link to your marketing piece.
The first box will allow you to select a thumbnail title and description for the Twitter post.
Click Post to Twitter and you will be prompted to sign in to Twitter if you have not already done so. The last step will allow you to add an additional comment, and customize your Tweet.
Click Tweet and it will be posted. Of course, if anything should go wrong and you would like the piece removed, you can always log in to Twitter and delete the tweet.
