Klaviyo is the heavyweight in ecommerce email and SMS, and it can do almost anything. The trade-off is real: it charges by list size, it takes time to learn, and you build every flow on a blank canvas.

Sendflo takes the opposite approach. You describe a goal in plain English, the AI builds the entire flow, and you only pay for the emails that actually send.

Where Sendflo wins

Pricing that doesn’t punish growth

Klaviyo bills per contact, so a bigger list costs more even if you rarely email it. Sendflo keeps your whole list free and charges per send — store 50,000 contacts and pay nothing until you email them.

It builds itself

Instead of a blank flow builder, you type “win back customers who haven’t ordered in 90 days” and Sendflo writes the emails, picks the timing, and assembles the automation. You just review and publish.

Deliverability you can see

Sendflo shows live inbox-vs-spam rates, cleans dead addresses automatically, and makes domain setup painless — so you can actually tell whether your emails are landing.

Where Klaviyo still makes sense

If you need deep, highly custom segmentation and a huge library of niche integrations, Klaviyo’s maturity is hard to beat. We’re not cloning every feature — we’re the simpler, fairer, AI-native alternative for stores that want results without the complexity or the per-contact bill.
