# Velocidi Changelog

## New Features
* Email Predictions added to segment builder: Velocidi clients can now use the segment builder to create segments based on predicted email behavior such as user likelihood to click, open, or unsubscribe. These segments will be used in activations with email providers like Mailchimp. Marketers can use them to optimize email delivery in campaigns, finding an ideal time and frequency of emails for each customer.

✏️ maybe "marketers can use them to optimize to whom they deliver each campaign, maximizing clicks or openings, while reducing unsubscriptions.". We could also address here that users are not all the same, and while some will open and click all emails, other start to lose interest, so they can use this to keep a pace of email delivery that keeps the user engadged, backing off or changing strategy when the user starts losing interest.

the feature is the email predictions. the segment builder is just the UI around the feature. we should focus on the new predictive behavior over email interaction 

* Next Purchase Date added to segment builder: Velocidi clients can now segment users according to when they are likely to make their next purchase. This includes customers who are likely to make a purchase in the near future, and customers who are overdue for a purchase. These rules can be specific to product categories or for any purchase of any category. And they remain dynamic, reflecting predictions based on each customer's event history.✅

✏️this is also the final implementation of the bigger timely re-engagement. we should elaborate that we now predict the next purchase date and are able to create dynamic segments around that prediction, with a screenshot for *likely to buy next 7 days*.
