Storyboard Text

  • While in a store, Dave is browsing through his emails. He notices a new email coming in and quickly opens it.
  • The user sees that the email is only a subscription to the Spotify service he uses.  Dave is tired of receiving so many advertisements emails and proceeds to look for a unsubscribe button.
  • After opening the email, at the bottom of the message, he sees a hyperlink that will allow him to unsubscribe from news letters.
  • Thank you for your subscription to Spotify news. New releases, new artists, and upcoming events near you! Click here to see more info! To unsubscribe from our newsletters. Click here
  • The service will pass information to SendGrid in order to check in their database that the user has unsubscribed.  Using SendGrid's bloom filter, we will be able to immediately get results about a user's subscription
  • Do not unsubscribe
  • Click here to unsubscribe
  • SendGrid Bloom Filter
  • SendGrid's bloom filter, located in the cloud, gives almost immediate results about the user's subscription. It checks its database, also located in the cloud, in order to see if the user's email is subscribed or not. 
  • Bloom filter Database
  • Knowing how quickly SendGrid's bloom filter is, Dave feels reassured that he will not be receiving any Spotify emails.
