Common questions

Is Constant Contact better than Postscript for a small business that doesn't sell online?

Yes. Constant Contact is built for email and event marketing, which works for any small business. Postscript only works with Shopify stores, so it's useless if you don't sell products online.

Can I use Postscript without Shopify?

No. Postscript is designed exclusively for Shopify stores. You must have a Shopify account and install the Postscript app from the Shopify App Store to use it.

Which tool is easier to set up for a beginner?

Constant Contact is easier for a complete beginner because it guides you through domain authentication, contact import, and campaign creation with a drag-and-drop editor. Postscript is easy if you already use Shopify, but you still need to configure SMS compliance and opt-in tools.

Do either of these tools have a mobile app?

No. Neither Constant Contact nor Postscript offers a mobile app, so you cannot manage campaigns or view analytics from your phone.

Which tool gives better return on investment?

Postscript claims a 34x ROI on SMS spend for Shopify stores, which is very high if you have a strong customer list. Constant Contact's ROI depends on your email list quality and campaigns, but it's generally lower than SMS for direct sales.

Can I send both email and SMS with Constant Contact?

Yes. Constant Contact supports both email and SMS marketing campaigns, plus event marketing. Postscript only does SMS.

Constant Contact wins for everyday email and event marketing; Postscript is a powerful but narrow SMS tool for Shopify store owners only.

If you run a local business, club, or nonprofit and need to send emails and manage events, go with Constant Contact — it's easy, reliable, and has real human support. If you own a Shopify store and want to turn text messages into a profit center, Postscript is your best bet, but be ready for the cost and the SMS-only focus.
