SMS Marketing for Shopify Stores
SMS is billed per message on top of any monthly fee, so the cheapest tool depends on how many texts you send. The main choice is between an SMS-only platform such as Postscript and SMS built into your email tool, such as Omnisend or Klaviyo.
These guides compare published per-message rates, minimums and monthly fees, with sources and check dates. Before you text customers in the US, make sure you have their consent – see email marketing rules for online stores for the email side.
