The simple way to choose

If the channel you care about is SMS, look hard at Postscript. If the channel you care about is email, look hard at Sequenzy.

Postscript grew up around Shopify SMS. It is good at collecting phone numbers, sending compliant text campaigns, and turning Shopify events into SMS flows.

Sequenzy does not try to be that. It focuses on writing and sending useful email automation, including cart recovery, welcome flows, post-purchase follow-up, transactional email, and subscription lifecycle email.

Where Postscript wins

Postscript wins when your customers buy from texts. It is more specialized for Shopify SMS, and that specialization matters. SMS has different compliance, consent, deliverability, and conversation patterns than email.

Where Sequenzy wins

Sequenzy wins when SMS is not the main thing. It works for Shopify and WooCommerce, handles transactional email, and can use Stripe billing data for subscription businesses.

If you sell products and subscriptions, or you want a simpler email tool next to a separate SMS tool, Sequenzy is the cleaner choice.
