A nonprofit does not run SMS to attribute revenue to a Shopify cart. You run it to move donors, volunteers and advocates to act — and to do it on a budget that answers to a board. So the criterion that decides it is true cost on a nonprofit's terms: published nonprofit discounts, no per-seat bloat, and clean 10DLC compliance so your messages actually land. We reweighted toward real cost and deliverability, then ease for a small staff or volunteers, and we name the expensive wrong-fit trap that the generic 'best SMS' lists will push you into.
For a nonprofit the deciding number is total cost per useful message sent, after any nonprofit discount, with compliance handled for you. We lifted weight onto real pricing and 10DLC deliverability, then ease of use for a lean team that may hand the keys to a volunteer. Slick ecommerce automations score almost nothing here, because attributing donations to a text is not how a nonprofit measures a campaign — reach and response are. See the full rubric →

SimpleTexting
Best for most nonprofits
SimpleTexting hits the nonprofit sweet spot: a published 15% discount for tax-exempt orgs that stacks with annual billing, credits that roll over a month so a quiet period does not burn your budget, free inbound messages, and keywords plus two-way inbox for donation and advocacy campaigns. The interface is genuinely volunteer-friendly. For a small org that wants predictable cost and real campaign tools without a sales call, this is the pick.
EZ Texting is one of the easiest tools to learn and offers custom nonprofit pricing if you call sales, which can beat list price at volume. The honest catch is the add-ons: extra user seats run about $10/month each and the entry plan carries a telecom fee, so the sticker and the bill diverge. Strong for a nonprofit that wants a friendly builder and will negotiate the discount — just price the real total with seats included.
TextMagic is pure pay-as-you-go at about $0.049 per SMS with no monthly plan to commit to, which is the lowest real cost for a nonprofit that texts irregularly — an annual appeal, an event reminder, a volunteer call-out. You buy credits and spend them; nothing expires into a subscription. The trade-off is a more utilitarian toolset and a $10/month fee per toll-free number for two-way. Ideal for spiky, occasional sending rather than always-on campaigns.
Sakari is built for two-way conversations and deep CRM ties (HubSpot, Salesforce), with rollover credits and unlimited users on every plan. For a nonprofit running a donor CRM and wanting texts to sync against contact records, that integration earns its place. It is priced and designed more for sales-style outreach than mass advocacy blasts, and per-message cost runs higher than SimpleTexting, so it fits relationship texting better than big sends.
Postscript is an excellent SMS tool — for Shopify ecommerce. It is built around store events, cart recovery and revenue attribution, requires a Shopify store, and prices on a usage model tuned to sales. For a nonprofit it is the classic wrong-fit: no nonprofit discount, no advocacy tooling, and a billing model that assumes you are selling product. It earns its place here only to mark the trap the generic lists set.
What matters most when a nonprofit picks an SMS tool?+
True cost after the nonprofit discount, paired with clean 10DLC compliance. A nonprofit measures a campaign by reach and response, not revenue attribution, so the deciding factors are a price your board accepts and deliverability that gets the message through. Tools with a published nonprofit discount and rollover credits protect a tight budget; the ecommerce-grade automation that dominates generic reviews is close to worthless for advocacy and donations.
Which SMS tool is cheapest for a nonprofit?+
It depends on volume. For irregular sending — an annual appeal, event reminders — TextMagic's pay-as-you-go at about $0.049 per SMS is the lowest real cost because nothing commits you to a subscription. For steady monthly campaigns, SimpleTexting's plans minus the 15% nonprofit discount, with rollover credits, usually win on cost per useful message. Estimate your monthly volume first, then pick the pricing model that matches it.
Do we have to register for 10DLC, and will these tools help?+
Yes — sending application-to-person SMS to US numbers requires 10DLC brand and campaign registration, and skipping it tanks deliverability or gets you blocked. All four nonprofit-fit tools here guide you through registration and handle the carrier paperwork; it is table stakes, which is why it does not separate them. Budget a one-time setup step and a small registration fee, and keep your opt-in language clean to stay compliant with the TCPA.
Why not just use the SMS tool that tops the 'best of' lists?+
Because those lists are dominated by Shopify-native tools — Postscript, Klaviyo SMS, Attentive — built and priced for ecommerce revenue. They need a store, offer no nonprofit discount, and their headline feature, attributing sales to a text, is irrelevant to a donation or advocacy campaign. For a nonprofit they cost more and do less of what you need. Start from the nonprofit-fit shortlist above instead.
