Rates checked on 11 November 2026. Klaviyo rates are from Klaviyo's in-account rate card (version 2026.Q4.01) and include carrier fees; your account's rates can differ, so check Settings > Billing in Klaviyo. Klaviyo bills mobile messaging through a monthly plan amount, so your bill is the plan you choose, not the exact usage shown. Postscript rates are from its public pricing page; carrier fees are estimated from Postscript's published averages and are billed at cost. One SMS means one segment (160 characters, or 70 with an emoji); longer messages count as more than one. Email, platform add-ons, short code rental and taxes are not included.
