Oco Uk review for Klaviyo: Email Marketing & SMS

We've used Mailchimp, Campaign monitor, Constant Contact, but Klaviyo is in a league of its own! Amazing app for sending bulk emails and also for setting up flow sequences.In particular it's Shopify integration is far superior which make segmenting customers so easy. For example, if your want to send a sale promo email but exclude customers who have purchased in last 30 days it's extremely easy! Fantastic app - highly recommended.
