🥇 Best for a local business: SimpleTexting
If you're texting customers about promotions, appointments, events, specials, or repeat business, I'd strongly consider this one. It supports mass texting, two-way messaging, MMS, drip campaigns, segmentation, APIs and analytics. Its current example plan is $39/month for 500 credits, with additional carrier fees. simpletexting.com
SimpleTexting
🥇 Best for a large ecommerce brand: Attentive

If you tell me your business type, number of contacts, and roughly how many texts you want to send per month, I can narrow this down to the cheapest 2–3 options and estimate your monthly cost.
If you're choosing SMS marketing software in 2026, these are the strongest options:
| Platform | Best for | Why |
|---|---|---|
| Klaviyo | E-commerce / Shopify | Excellent segmentation, automations, email + SMS in one platform |
| Attentive | Large e-commerce brands | SMS-first platform, strong list growth, personalization, AI and RCS |
| SimpleTexting | Small businesses | Very easy campaigns, two-way texting, scheduling and integrations |
| EZ Texting | Mass texting | Straightforward bulk SMS/MMS and easy setup |
| SlickText | Promotions & list growth | Good opt-in tools, keywords, loyalty and automated campaigns |

Zapier's 2026 comparison similarly puts SimpleTexting at the top for easy SMS campaigns, Twilio for customization, and Attentive for large e-commerce brands. zapier.com
🥇 Best overall for e-commerce: Klaviyo
If you sell through Shopify or another online store, I'd start here. You get sophisticated customer segmentation, abandoned-cart/welcome flows, email + SMS automation, and revenue attribution. Klaviyo currently offers a free tier, although its mobile messaging is now priced on a per-message basis. www.klaviyo.com
🥇 Best for a local/small business: SimpleTexting
If your goal is things like “10% off this weekend,” appointment reminders, promotions, or two-way customer texting, SimpleTexting is probably easier than the e-commerce-focused platforms.
🥇 Best for a large brand: Attentive
Attentive is particularly compelling if SMS is a major revenue channel. Its current platform supports SMS, MMS, RCS, email and push, with pricing based on subscriber/list size and message volume. www.attentive.com
🥇 Best if you need a custom app: Twilio
Choose Twilio when you have developers and want SMS integrated deeply into your own software, CRM, website, or workflows.
If you tell me what type of business you have, roughly how many contacts you have, and how many texts you expect to send per month, I can narrow this down to the best 2–3 options and compare their actual costs.
