STOA Verdict	Klaviyo is the go-to pick if you run an online store and want email and SMS marketing that actually ties back to sales. Its biggest strength is deep e-commerce data integration—especially with Shopify—so your messages respond to what customers do in real time. The main downside is that costs climb quickly once your contact list grows past a few thousand profiles, so budget accordingly as you scale.
