The best SMS marketing software depends on what you sell and what you already use. Klaviyo, Omnisend and Brevo suit businesses that want email and SMS together, Attentive and Postscript suit ecommerce brands that focus on text marketing, SimpleTexting and EZ Texting suit local and service businesses, Textmagic suits business texting and Twilio suits businesses with developers.
Text messages get seen. That's the whole appeal of SMS marketing, and also why it needs care. A well-timed text about an order, an appointment or a real offer is welcome. Too many, too often, and people reply STOP.
The tools below are well known and widely used. Some are built for ecommerce, some for local businesses and some for developers. I've focused on what each one is known for, so treat this as a shortlist and check each one supports texting in the countries where your customers live.
What should you look for in SMS marketing software?
- Consent tools. Opt-in forms, keywords and easy opt-outs keep you on the right side of the rules.
- Automations. Welcome texts, abandoned cart reminders and appointment reminders do the heavy lifting.
- Segments. Sending the right text to the right group matters more than sending more texts.
- Two-way texting. Customers will reply, so check you can answer them.
- Integrations. Links with your store, CRM or booking system keep texts relevant.
- Country coverage. Rules and support differ between countries, so check yours.

How to choose the right SMS marketing software
Start with consent. In most countries you need clear permission before sending marketing texts, and every message should make opting out easy. Choose a tool with good opt-in forms and keyword sign-ups, and check the rules where your customers live.
Then match the tool to how you sell. Ecommerce brands get the most from Klaviyo, Omnisend, Postscript or Attentive because texts can react to what shoppers do. Local and service businesses often do best with SimpleTexting, EZ Texting or Textmagic for reminders, offers and two-way chats.
Whichever you pick, start small. Set up one automation, such as a welcome text or an appointment reminder, and watch the replies and opt-outs before you add campaigns. It's much easier to grow a text list you haven't annoyed.
