How Klaviyo SMS Pricing Works

Klaviyo bundles SMS into a broader marketing platform. You pay a monthly plan fee that scales with your contact-list size, then buy SMS credits on top, charged per message at a per-country rate. For a store that only wants to send promotional blasts, that platform fee is pure overhead.

BuzzBlaster is pay-as-you-go: no monthly platform fee, just a per-message rate — around half of Klaviyo's in many markets. See the full per-country SMS cost table, compare tools on our CartBoss vs Klaviyo page, or read the Klaviyo SMS pricing guide.
