Klaviyo review
Klaviyo is an SMS marketing platform with a $0 entry point: its free plan covers 250 active profiles, 500 email sends and $5 of mobile messages a month (read September 9, 2026). There is no time limited trial. Texting beyond that allowance runs on a separate prepaid monthly Mobile Messaging plan. We score Klaviyo 4.58 out of 10.

When Klaviyo fits
Klaviyo fits a US ecommerce team already inside its ecosystem: the platform offers 350+ integrations including Shopify, Wix and BigCommerce (read September 9, 2026). Choose it for campaign and flow based SMS to opt-in subscribers at moderate volume, using the toll-free number created automatically at setup, which is free. Drag and drop editors, segmentation and a permanent free plan with $5 of monthly mobile messages suit a small budget testing SMS. Klaviyo offers RCS for Business with verified profiles, read September 28, 2026, though the page does not state US availability; our RCS for business page covers the channel.
When to look elsewhere
Look elsewhere when you need published per-message pricing: Klaviyo does not publish a US rate per message, short code fees, 10DLC fees or MMS rates (checked September 9, 2026). Reliability is hard to judge because Klaviyo does not publish an uptime figure (checked September 9, 2026). Long code sending is not offered in the US, and monthly plan spend does not roll over, so you pay again each month for the allowance you need.
