Drip is an ECRM (Ecommerce CRM) that offers you the ability to market to your customers in a more personalised and strategic manner. This is achieved by selectively capturing engagement data from your customers as they interact with your website or app, and then using that information to serve more content to them across the likes of email marketing and social media.
This plugin records activity in your Drip account when a visitor performs actions on your Craft CMS website:
Account created Customer logs in Customer logs out Customer updates their profile
Additionally, if you use Freeform, you can also track form submissions which is incredibly useful to associate initial contact with customers through to conversion.
