Klaviyo: Email Marketing & SMS

Klaviyo is an excellent tool, and is structured in a way that makes the most of customer data. It's fully integrated with Shopify. The flows that come out of the box are valuable ways to attract new customers and automate marketing/customer support. You can segment and focus different campaigns on VIP customers. Their success and support teams are great.

We are converts from Mailchimp and won't look back.
