Moving from SlickText to Postscript means trading the problem above for this honest limit: Shopify-only. What you gain: SMS as a revenue channel, not a discount cannon, at approximately from ~$100/mo + usage. Plan the migration in that order — export your data from SlickText first, rebuild the core workflow in the new tool, and run both in parallel for one cycle before cancelling. Budget-sensitive teams should also look at Sendlane (7.9/10, from ~$100/mo) before committing.
| Your situation | Pick |
|---|---|
| Shopify, revenue-focused | Postscript |
| Enterprise scale + growth units | Attentive |
| Already deep in Klaviyo | Klaviyo SMS |
| Entry price, ecom flows | Yotpo SMS |
| One vendor for email+SMS | Sendlane |
SMS marketing platforms run the highest-attention channel in commerce: list growth with compliant consent, automated flows, campaign sends, conversational replies and revenue attribution. The field splits into Shopify-native leaders, enterprise growth machines, email-bundled options and generic broadcast tools.
Generic texting tools can't see orders, so they can't trigger abandonment flows or attribute revenue. For stores, Shopify-native data depth (Postscript's lane) is the entire product.
TCPA suits are a real industry with real settlements. Platforms with consent capture, quiet hours and opt-out handling built in protect you from mistakes your intern will otherwise make.
SMS tolerates far fewer sends than email. The platforms that win help you earn more per message (segmentation, conversational AI) rather than send more messages.
Klaviyo SMS inside your email platform means one profile and one journey builder; specialists bring deeper SMS features. The bundle usually wins below ~$20k/mo SMS revenue; specialists above.
Platform fees run $100+/mo plus per-message carrier costs (roughly $0.01–$0.03 per SMS in the US, more for MMS). Enterprise contracts (Attentive-class) are custom and sales-led. Model cost per incremental order, not cost per message — a smaller, hotter list beats a big numb one on every line.
Two-way SMS with AI handling sizing, shipping and product questions turned a broadcast channel into a selling channel.
Rich messaging (images, carousels, buttons in the native thread) started real rollouts, with platforms racing to support it ahead of volume.
Carrier filtering and regulatory pressure keep rising, quietly killing gray-area list-building tactics and rewarding clean double opt-in programs.
