Attentive vs Postscript FAQ
Can I migrate from Postscript to Attentive (or vice versa)?
Yes — both platforms support subscriber list imports. Your SMS subscribers (opted-in contacts) can be migrated, though you'll need to verify you have proper consent documentation. Automation flows need to be rebuilt. Most brands allow 60-90 days for a full migration. If moving from Postscript to Attentive, budget for a few weeks of parallel running to validate deliverability.
Does Postscript work with non-Shopify platforms?
Postscript is purpose-built for Shopify and does not natively support other platforms. If you're on WooCommerce, BigCommerce, or Magento, Postscript is not the right choice. Attentive, Klaviyo, or SimpleTexting have broader platform support.
Which has better deliverability — Attentive or Postscript?
Both platforms have strong deliverability since they manage their own carrier relationships and 10DLC compliance. Attentive's sending infrastructure is battle-tested at higher volumes (they work with brands doing millions of messages). For smaller brands, both will deliver similar deliverability rates (typically 95-98%+).
Can I use Attentive or Postscript alongside Klaviyo?
Yes — many brands use Postscript for SMS and Klaviyo for email, integrating via native integrations that sync subscriber data and suppress opted-out contacts. Attentive now includes email functionality, so you can replace Klaviyo with Attentive if you prefer a unified platform. Both approaches work well; it depends on whether you prefer specialized tools (Postscript + Klaviyo) or a unified suite (Attentive).
