For an ecommerce store, SMS blast software is a choice between standalone texting tools that sell monthly message credits, such as SlickText from $29 for 500 credits and SimpleTexting from $29 for 500 credits plus a number, and ecommerce marketing suites that add SMS to email, such as Klaviyo, Omnisend and Privy. Compare them on billing unit and what happens to unused budget, on the Shopify data each can use, on the sending speed of the number you will use, and on how replies reach your team. Pick the broadcast tool on those points, then decide separately who owns the conversations a blast creates. Zobi is an option for the personal recovery, support and reorder conversations, with messages written for the shopper and approved by you.
