Sanj, for eCommerce, the typical go to is Klaviyo. You can also play with Mautic if you want to go open source, Adobe Campaign, Bronto, etc. We personally use Drip and prefer it over Klaviyo. Being partners with Drip also helps us get the features we want for eCommerce (happy to do a demo, if you're looking at it). On a smaller scale, if you're doing lead generation, but not really any abandoned cart stuff which needs to pull data from your store, then you can go with stuff like ActiveCampaign and InfusionSoft. Drip is a hybrid.
