Best Postscript alternatives for ecommerce SMS marketing

Searching for Postscript alternatives usually comes down to one thing: you need more than SMS for your Shopify store.

Postscript is a solid choice when SMS is your primary channel, letting you send campaigns, build automations, and master that one channel well. 

But when email and multichannel marketing are also core to your strategy, its SMS-only coverage starts to feel limiting. Covering one channel means there’s also a good chance you’ll end up paying for at least one more tool to cover the rest.

The best Postscript alternatives have either multichannel capabilities, lower costs, or more suitable SMS features, such as better revenue reporting. This article explores the 10 tools we recommend for your ecommerce store.

Why consider a Postscript alternative?

Postscript is highly rated for SMS marketing, but it has channel and cost limitations that could steer you towards alternatives.

These are the main reasons to consider alternatives to Postscript:

• You need email marketing capabilities. Postscript is an SMS tool without email. It integrates with multiple email tools, but only for syncing data such as contacts and custom properties.
• Your store requires a multichannel strategy. For the likes of abandoned carts, back-in-stock alerts, order confirmations, and other time-sensitive messages. Postscript is only suitable for covering your SMS automations.
• You need unified customer profiles and lifecycle maps. Postscript’s subscriber data is SMS-only, so it can’t build cross-channel profiles or visualize the customer journey.
• Your budget doesn’t match the pricing. Postscript charges per SMS plus a monthly plan. Starter has a $49/month minimum spend, Growth starts from $100/month, and Professional is at least $500/month.
• You don’t want significant feature restrictions. Only Postscript’s Professional plan includes Enhanced Analytics and priority live chat/email support, and its AI tools sit in a separate AI Plan sold as an add-on rather than included in any plan.

How to choose the best Postscript alternative

Picking the right Postscript alternative for your store comes down to what channels you prioritize, the features and integrations you require, and your budget. Follow these six steps to narrow your choices and create a shortlist:

1. Decide on an SMS-only or multichannel tool. There are decent options for both. For SMS, consider TxtCart and EZ Texting. For multichannel, look at Omnisend and Klaviyo.
2. Compare channel capabilities. Some SMS tools only let you send marketing texts; others also let you send transactional texts. You might need both. The same goes for email if you’re looking at a multichannel tool.
3. Consider built-in compliance for your markets. Your tool should meet the latest compliance requirements for SMS marketing as per TCPA/CASL/GDPR.
4. Check ecommerce platform and integration support. The best Postscript alternatives have a native app for Shopify, and ideally, WooCommerce and other platforms, just in case you build on something other than Shopify in the future. They also offer native integrations for your apps, such as Judge.me.
5. Assess the tool’s reporting features. Your marketing and transactional texts have revenue and retention potential. Reports should include revenue attribution and properly track placed orders and revenue per message sent.
6. Determine your monthly spend and assess credit and plan prices. Consider not only the per-credit price but also credit bundle prices, volume discounts, and any additional plan requirements.

Conclusion

Postscript is an excellent Shopify SMS app, but its sole focus on SMS and a minimum $100/month spend for a plan that doesn’t limit opt-in keywords will lead you to alternatives.

For multichannel — as in, consolidating your email and SMS efforts — Omnisend is our top pick of Postscript alternatives for its global SMS, advanced flows and segments, and AI features. You only need one tool, plus it has multi-store support for all your brands.

Attentive, EZ Texting, and Sender are also interesting; Sender for email-first brands, EZ Texting for collecting payments via text, and Attentive for strategic support. Your next step is to compare each tool’s pricing and take free trials where available.

FAQs

What is the best Postscript alternative for Shopify?

Omnisend is the best multichannel Postscript alternative for its global SMS coverage, email mastery, and deep Shopify integration. TxtCart is a top pick for an SMS-only alternative, with more AI features and a lower minimum spend.

What’s better, Klaviyo SMS or Postscript?

Postscript suits you if SMS is your core channel and you send email in another tool, such as Shopify Messaging, whereas Klaviyo SMS is a good fit when you want email and SMS working from the same customer profile.

What are the disadvantages of Postscript?

Postscript has no email or multichannel capabilities. Also, pricing is a big disadvantage, requiring a $49/month minimum spend for the Starter plan with only two opt-in keywords and no live chat or email support. It’s then $100/month for the Growth plan with unlimited keywords and customer support.

Are there any free Postscript alternatives?

There are no 100% free alternatives. Klaviyo’s free plan includes 150 SMS credits, but you’ll burn through them fast, and the 250-active-profile limit might not suit you anyway. Your best bet on a tight budget is an SMS tool with a low-cost monthly plan and credit bundles. Example – Omnisend’s Pro plan is $59/month, and you can buy SMS credits on top for $10/month.
