Postscript review

A top-tier SMS platform adding email capabilities.

Verdict

Postscript is a wildcard because it approaches the problem from an SMS-first perspective, offering best-in-class text message marketing with a recently added, and rapidly improving, email channel.

What customers praise

Its deep Shopify integration for SMS is unparalleled, enabling triggered texts based on shipping status changes (e.g., 'Your order has shipped!') that see over 98% open rates.

What customers criticise

The email marketing feature set is still in its early stages and lacks the advanced segmentation, template library, and analytics of the email-first platforms on this list.

Best for

SMS-first ecommerce brands that want to consolidate their email marketing into the same platform for unified campaign management.
