SimpleTexting

SimpleTexting charges by message credits rather than a flat send-and-forget rate, and every plan gets the same feature set, automation, API access, keyword-based opt-ins, and drip campaigns, so there's no upgrade tax for basic functionality. A standard SMS uses one credit, a longer message over 160 characters uses two, and an MMS with an image uses three, which makes it easy to estimate cost once you know your typical message length.

Plans run from 500 credits at $39 a month up through 50,000 credits near $909 a month, with custom pricing above that, and three user seats come included on every tier. On top of the plan price, expect a telecom surcharge of roughly $8 a month per phone number plus a one-time $4 carrier registration fee required for U.S. compliance. It's a solid fit for a small or mid-size business that wants SMS marketing software without needing deep ecommerce platform integrations, since the feature set stays the same from five hundred texts a month up to fifty thousand.
