Klaviyo: Email Marketing & SMS

I've been in CRM for over a decade. If you use Shopify, hands down this is the best email marketing platform you can use.

The editor and segment creator are easy to use and include advance features. Also, integrations into Shopify and most Shopify apps take just minutes to set up. Outside of that, you get unlimited support and a dedicated success manager. My personal opinion...Klaviyo should be on every marketer's short-list when considering a new ESP.
