I tested 5 Postscript alternatives in 2026 (Free & Paid)

Postscript just did something genuinely controversial in 2026. They killed the $200 credits plan that loyal customers built their businesses on.

They forced existing users onto new tiers with a $49 monthly minimum spend, even on the “free” plan. Shopify App Store reviews tell the story.

February 2026: “I LOVED Postscript. And then this year, they instituted a new monthly charge in ADDITION to per-message charges. I had to uninstall to receive my refund.”

April 2026: “They offer a ‘free plan’ but charge you $49 even if you didn’t send any text messages. A scam for small business owners, this fee wasn’t included in the free plan when I signed up.”

If you’re searching “Postscript alternatives” in 2026, you’re probably not just price-shopping. You’re betrayal-shopping. I tested 5 alternatives across free and paid tiers. Here’s the pricing change that frames everything:

I tested 5 alternatives. Each one fixes a specific Postscript trade-off: cheaper, multi-platform (not just Shopify), bundled with email, or different positioning entirely. Find your situation, then read those tools.

What Postscript still does best (and the 5 reasons people are leaving)

Worth saying upfront: the product itself is still excellent. The Shopify-native integration is the deepest in the category. Infinity Testing AI automatically tests hundreds of variants. The in-house compliance engine protects merchants from costly TCPA lawsuits.

2,423 Shopify stores currently run Postscript. 4.5+ stars across hundreds of reviews on the Shopify App Store. ATTN Agency’s 2026 review called it “the best dedicated SMS marketing platform for Shopify stores. Full stop.”

So why is everyone shopping for alternatives? Five specific reasons appear across recent threads on the Shopify App Store, G2, and Software Advice.

Reason 1: The forced 2026 pricing migration

The headline grievance. Postscript killed the $200 credits plan and forced existing customers onto the new $49 monthly minimum Starter tier. Unused credits stopped rolling over.

The Shopify App Store has dozens of recent reviews using language like “scam” and “had to uninstall to get my refund.” For brands that built workflows around the old credits model, the change broke trust.

Reason 2: Shopify-only ecosystem

Postscript works exclusively on Shopify. No WooCommerce. No BigCommerce. No Wix. No custom platforms. ATTN Agency explicitly flags this: “If you are on WooCommerce, BigCommerce, or another platform, this is not for you.”

For brands considering platform migrations or running multi-platform operations, the Shopify lock-in becomes a real constraint. The deeper your Postscript investment, the harder a future replatform becomes.

Reason 3: Customer service quality declined post-October 2024

The mobile-text-alerts.com analysis frames it directly: “Up till around October of 2024, most comments about Postscript’s customer service were positive. But things seem to have gone downhill from then.”

Recent Software Advice reviews include: “Their customer service is terrible. They will lock you into long-term plans and charge you even if you don’t want to use the product.” The product team grew faster than the support team.

Reason 4: Native reporting over-attributes revenue

Headwest Guide’s review is explicit: “Postscripts native reporting will over-attribute sales to their channel. Many customers we spoke with used Google Analytics as their source of truth for attribution.”

The dashboards look great. The actual Shopify revenue doesn’t always match. Agencies managing Postscript routinely cross-reference both before trusting the ROI numbers.

Reason 5: No native email channel

Postscript is SMS-only. For a unified retention strategy, you need to pair it with Klaviyo or another email tool. That’s two billing relationships, two attribution layers, and two integrations to maintain.

For brands wanting one tool for email + SMS, Postscript forces a tool-pairing decision that competitors like Klaviyo SMS and Omnisend solve natively.

Shopify-native vs platform-agnostic matrix

Here’s what each alternative trades on. Postscript wins on Shopify integration depth. Others win on platform flexibility, unified email + SMS, or transparent pricing.

The honest takeaway: Postscript’s Shopify-only constraint is the biggest filter. Klaviyo SMS and Omnisend win for multi-platform brands wanting unified email + SMS. Attentive and Yotpo SMS compete on the depth of enterprise features. Emotive and EZ Texting hit specific niches.

The 3 free or freemium Postscript alternatives

Start here if budget is the primary constraint or the new $49 Postscript minimum hurts.

Each tool below uses the same four-part profile: what it does, what Postscript doesn’t, where Postscript still wins, total monthly cost at typical volume, and best for.

1. Klaviyo SMS: unified email + SMS with a real free tier

What it does Postscript doesn’t: Email and SMS on one platform with unified attribution, profiles, and segments. Genuine free tier (150 SMS/month, 250 contacts). Multi-platform support beyond Shopify. No forced minimum spend if you send zero messages.

Where Postscript still wins: SMS-specific feature depth (45+ Shopify-native segmentation filters). Infinity Testing AI for variant optimization. In-house compliance engine. CashBack integration for margin-protecting list growth. Postscript was built SMS-first; Klaviyo added SMS later.

Total monthly cost at typical volume: Klaviyo Free up to 150 SMS/month. Email starter at $20/month for 500 contacts. Email + SMS combined at $85/month for 2.5K contacts and 1,250 SMS credits.

SMS at $0.008/SMS plus carrier fees. At 25K SMS sends/month, expect $200-400/month combined with email.

Best for: Brands with under $5M in GMV seeking unified email + SMS attribution. Multi-platform stores (WooCommerce, BigCommerce) that Postscript doesn’t support. Teams burned by the Postscript pricing change want genuinely transparent costs.

2. Omnisend: multi-channel free tier across email, SMS, and push

What it does that Postscript doesn’t: a genuine free plan (500 contacts, 60 free SMS credits monthly). Multi-channel: email, SMS, push notifications, and web push in one tool. Multi-platform: Shopify, WooCommerce, BigCommerce, Wix. Strong on automation templates for ecommerce.

Where Postscript still wins: SMS-first DNA and Shopify-native feature depth. Conversational commerce via Shopper AI. Compliance engine and TCPA defensibility. Native CashBack integration. Postscript’s SMS-specific tooling outpaces Omnisend’s broader multi-channel approach.

Total monthly cost at typical volume: Omnisend Free tier covers 500 contacts and 60 SMS credits. Standard at $59/month for 6K contacts. Pro at $99/month for unlimited emails.

SMS credits sold separately at $0.0150 per US SMS. At 25K SMS sends/month, expect $400-$600/month combined.

Best for: Multi-channel ecommerce brands wanting email, SMS, and push notifications in one platform. WooCommerce or BigCommerce stores that Postscript doesn’t support. Brands under $5M GMV running broader retention automation across channels.

3. EZ Texting: SMB-friendly with transparent monthly pricing

What it does Postscript doesn’t: Multi-platform support, not just Shopify. Strong on service businesses, local marketing, appointment reminders, and bulk SMS use cases. Free trial without forced minimum spend afterward. Built for SMB rather than enterprise DTC.

Where Postscript still wins: Ecommerce-specific features (cart abandonment, browse abandonment, post-purchase flows tied to Shopify data). Infinity Testing AI. Conversational commerce. Compliance engine. EZ Texting is broader but less e-commerce-tuned.

Total monthly cost at typical volume: EZ Texting Launch at $25/month for 500 messages. Boost at $75/month for 2K messages. Scale at $230/month for 7,500 messages. At 25K SMS sends/month, expect $400-$600/month with no forced minimum. Predictable monthly pricing.

Best for: Service businesses, local retailers, and non-ecommerce SMS use cases. SMB brands want predictable monthly costs without the Postscript-Attentive pricing escalation. Teams sending under 25K messages/month with simple use cases.

The 2 paid PostScript alternatives

Step up here when you’ve outgrown free tiers and need genuine enterprise SMS depth.

4. Attentive: enterprise SMS for $20M+ GMV brands

What it does Postscript doesn’t: Patented sign-up technology for list growth. AI personalization breadth (send time AI, journey AI, content AI). Multi-channel SMS + email + RCS. White-glove concierge onboarding with dedicated CSM. Multi-platform support beyond Shopify.

Where Postscript still wins: Transparent pricing without quarterly minimums. Month-to-month contracts (Attentive requires 6-12 month commitments with auto-renewal). Self-service list management. Lower entry point. Genuine TCPA compliance defensibility.

Total monthly cost at typical volume: Attentive custom quote with $2,000-$3,000 quarterly minimums. Carrier fees nearly double the quoted costs in practice. At 25K SMS sends/month, expect $1,500-$3,000/month effective. Postscript Professional equivalent: $500-$900/month.

Best for: $20M+ GMV DTC brands with dedicated retention teams. Apparel, beauty, food/beverage brands where SMS drives 15%+ of revenue. Teams willing to lock in 12-month contracts for enterprise concierge support.

5. Emotive: premium SMS with AI plus human hybrid

What it does Postscript doesn’t: Combines AI automation with live human agents for conversational SMS replies. Stronger on premium DTC positioning where brand voice consistency matters in two-way interactions. Multi-platform support beyond Shopify.

Where Postscript still wins: Shopify-native segmentation depth. Infinity Testing AI for variant optimization. Lower entry pricing without enterprise minimums. CashBack integration for list growth. Self-service onboarding.

Total monthly cost at typical volume: Emotive entry at $300+/month, custom quote with annual contracts. At 25K SMS sends/month, expect $800-$1,500/month. Postscript Professional equivalent: $500-900/month. Emotive is premium-priced.

Best for: Premium DTC brands ($5-20M GMV) wanting human-AI hybrid conversations. Beauty, fashion, and food brands where two-way SMS replies need a consistent brand voice. Teams willing to accept annual contracts for premium service.

What you actually pay at 10K, 25K, 100K SMS sends per month

The pricing trajectory most “Postscript alternatives” articles skip. Here’s what each tool costs as your SMS volume grows.

At 10K SMS sends/month (testing the channel):

Postscript Starter $49 minimum plus $0.015/SMS = $199/month. Klaviyo SMS Free tier handles 150 SMS; then $80-$150/month for combined email and SMS. Omnisend Free covers 60 SMS, then $200-300/month combined.

EZ Texting $230/month Scale tier. Attentive $1,500-$3,000 effective. Yotpo SMS: $300-$500/month. Emotive $800-1,000/month.

At 25K SMS sends/month (early growth):

Postscript Growth $100 plus $0.01/SMS = $350/month. Klaviyo SMS: $200-$400 combined with email. Omnisend $400-600 combined. EZ Texting $500-700/month with credits. Attentive $1,500-$3,000 effective. Yotpo SMS: $500-$800/month. Emotive $800-1,500/month.

At 100K SMS sends/month (mid-scale):

Postscript Professional $500 plus $0.007/SMS = $1,200/month. Klaviyo SMS: $800-$1,200 combined. Omnisend $1,200-1,800 combined. Attentive $4,000-$6,000 effective. Yotpo SMS $1,000-2,000/month. Emotive $2,000-3,500/month.

The savings get meaningful below 25K SMS/month. Klaviyo SMS Free and Omnisend Free both beat Postscript’s new $49 minimum at low volumes. For above 100K SMS/month, Postscript Professional becomes competitive again, with per-message economics similar to Klaviyo and Omnisend.

When Postscript is still the right call post-pricing-change

The contrarian case worth naming. Postscript’s product didn’t get worse in 2026; the pricing model did. Four specific profiles where the new math still works.

You’re a Shopify-only operation at $1M+ GMV: The Shopify-native integration depth is genuinely best-in-class. 45+ segmentation filters, 65+ trigger events, real-time Shopify data sync. At $1M+ GMV with SMS as a serious channel, Postscript’s depth pays off.

SMS drives 10%+ of total revenue: Once SMS is material to your business, the Infinity Testing AI and Shopper conversational commerce features start delivering measurable lift. Below this threshold, simpler tools cover the basics at a lower cost.

You value the compliance engine: Postscript’s in-house legal team and built-in compliance engine genuinely protect merchants from TCPA class action lawsuits. After the 2025 Johnson v. Human Power of N case, these matters. The compliance defensibility is real.

You’re an agency managing multiple Shopify client SMS programs: Postscript’s Shopify-specific workflows and partner program make multi-client management cleaner than generalized SMS tools. Agencies report it as the cleanest tool for scaling Shopify SMS operations.

If two or more apply to your business, Postscript’s pricing change probably won’t matter to your bottom line. If none apply, the alternatives are likely both cheaper and a better fit.

What I’d do based on your platform stack

Here’s how I think about the call, segmented by ecommerce platform (because Postscript’s Shopify exclusivity is the biggest filter for most readers).

Shopify-only, under $1M GMV: Klaviyo SMS free tier or Omnisend free tier. Postscript’s new $49 minimum is punishing at this scale. Prove SMS as a channel before paying for Postscript’s depth.

Shopify-only, $1-5M GMV: Klaviyo SMS or Postscript Growth tier. Both work at this revenue scale.

Klaviyo wins if you want unified email + SMS. Postscript wins if you’ve committed to a best-of-breed retention stack with Klaviyo Email and Postscript SMS separately.

Shopify-only, $5M+ GMV with dedicated retention team: Postscript Professional or Attentive. Postscript Professional at $500/month plus per-message rates usually beats Attentive’s $2K-$3K quarterly minimums for brands under $20M GMV. Attentive enters the conversation at over $20M in SMS budgets, with $10K+/month.

WooCommerce, BigCommerce, Wix, or custom platform: Klaviyo SMS, Omnisend, or Attentive. Postscript isn’t an option since it’s Shopify-exclusive. Klaviyo SMS for unified email + SMS on most platforms. Omnisend for multi-channel ecommerce.

Already running Yotpo reviews or loyalty: Add Yotpo SMS to the existing contract. The consolidated billing and unified customer profiles usually beat a separate Postscript subscription for Yotpo-committed brands.

Service business, local retail, or non-ecommerce SMS: EZ Texting or SimpleTexting. Both built for service business workflows where ecommerce-specific SMS features don’t apply. Predictable monthly costs without the Postscript-Attentive escalation.

Agency managing multiple Shopify SMS programs: Postscript still wins here, despite the pricing change. The partner program, multi-client workflows, and Shopify-native depth make agency operations cleaner than generalized tools.

Whichever platform stack you use, test the free tiers of the alternatives first. The Postscript pricing change makes 2026 the right year to evaluate options seriously. Klaviyo SMS, Omnisend, and EZ Texting all offer genuine free starts that let you compare before committing.

And if you’re staying on Postscript, negotiate. Multiple users report Postscript being responsive to retention conversations when you reference specific competitor pricing.

The product is still excellent. The new pricing tier is just where the conversation starts now, not where it has to end.
