Welcome back to the Klaviyo Data Science podcast! This episode, we dive into… Using data science to help people write Using machine learning models to generate text, images, and other creative objects is, as they say, a bit of a hot topic right now. There are examples of models like this in action all across the internet and across different fields and disciplines. Today, we discuss one of those fields in more depth: marketing. In particular, the Klaviyo data science team recently released the Subject Line Assistant tool, which helps marketers craft better subject lines. We take a close look at that tool, how it works, and the thinking behind it to examine what it looks like to use AI to help a human write. We’ve brought on four experts from Klaviyo, and you’ll hear about subject lines from a variety of angles, including: What a subject line is, and why it’s arguably the most important part of an email What holds people back from writing great subject lines and how the team went about solving those problems How a specialized human-in-the-loop model for a highly specific context can look “Subject lines are a very unique type of text generation problem. We’re not asking for a short story where there’s a lot of leeway to really hit a home run — you have a limited amount of space to communicate a brand message, communicate what the email is communicating, make a connection with your audience, and encourage them to interact.” - Josh Villarreal, Data Scientist Head over to the full show notes to see all the information about this episode!
