Klaviyo
The platform for unified customer data
Klaviyo is the gold standard for ecommerce email and SMS marketing, particularly for Shopify stores. Its deep integration with ecommerce platforms enables sophisticated automated flows like abandoned cart, post-purchase, and win-back sequences based on real purchase data.
Loops
The email platform built for SaaS
Loops is a developer-first email platform designed exclusively for SaaS companies, combining marketing and transactional email in a single clean interface.
