Best SMS marketing software
1 product compared on who they suit and what to pick instead. Facts checked November 4, 2026.
Klaviyo is the best pick for most online stores, because one flow can send an email, wait, and follow up with a text to the shoppers who didn't buy. Shopify stores that treat texting as their main channel should look at Postscript, and Omnisend's Pro plan suits stores that want their SMS credits included in the monthly price. For a local business that texts customers back and forth, SimpleTexting and EZ Texting cost less, and both can have a local number ready within a business day. Platformly suits businesses that want texts and email in the same flows while sending through their own Twilio or Vonage account.
