The MV Promo Blaster is a feature that will enable auto-tweets of your sales to your Twitter account once it's linked to your MV Account. This is a great way to promote your content automatically!
When you link your Twitter, the MV Promo Blaster will automatically be set up to your account. You can adjust the frequency of the auto-tweets by clicking the drop-down Menu > Marketing Tools > MV Promo Blaster (https://www.manyvids.com/MV-promo-blaster/).
You can choose between auto-tweets every 2 sales, 5 sales, 10 sales, 20 sales, 50 sales or never if you wish to turn it off.
You can also choose between tweeting a teaser vid, or a screenshot, under the "Tweet Type" selection:
