The verdict

For most online stores I would pick Omnisend. You can start on a free plan, you get email, SMS and push together, and you are not tied to one shop platform. If your brand is on Shopify and you want SMS to carry serious revenue, with opt-in tools and compliance help built around it, pick Postscript.

Check the cost shape before you decide. Omnisend plans scale with your contact count and SMS is billed per message. Postscript charges per message with carrier fees as a separate line, so costs follow your sending. Model a normal month and a peak month in either tool.

Who each is for

Omnisend logo

Choose Omnisend if…

Pick Omnisend if you want one account for email, SMS and web push, and you want flows that work from day one. It suits small and mid-sized stores that have outgrown a basic newsletter tool and do not need an enterprise platform.

The free plan lowers the cost of trying it, and free migration helps if you are moving from another platform. The free plan does not include SMS, so treat it as a trial that does not expire rather than a long-term home.

Choose Postscript if…

Pick Postscript if you sell on Shopify and want text messages to be a proper revenue channel. It has a visual flow builder, pop-ups and an onsite opt-in for list growth, custom attribution windows, and guardrails for consent and quiet hours.

It is also a good fit if you already run Klaviyo for email and want a dedicated SMS tool next to it. Skip it if you are not on Shopify, or if email is your only channel and you have no plan to add text messages.
