QUICK ANSWER
Klaviyo is the best Postscript alternative in 2026 for most stores because it adds email, SMS and push on one profile with a free plan for 250 profiles. Attentive is the best pick for large Shopify brands that want AI replies, and Textedly is the best pick for a store that wants the lowest flat monthly price.
Key takeaways
2 of 8 shortlisted tools have a free plan, and the lowest listed paid start is $0.0083 per SMS segment (Twilio) (Nov 2026).
Klaviyo ranks first because it covers the email Postscript lacks, on the same customer profile.
Postscript works only with Shopify, so four picks here exist for stores on other platforms.
Textedly and EZ Texting beat Postscript on flat monthly price for a small list.
The $49 monthly minimum spend is the main reason small stores leave Postscript.
Postscript is a strong SMS tool for Shopify stores, but it is not the right fit for every store. It works only with Shopify, its $49 monthly minimum spend bills in quiet months, and it has no email channel, so a store that wants one account for both channels looks elsewhere. This guide compares eight Postscript alternatives on price, free plans and fit, with a clear reason to switch for each one.
Switch if: Switch if you want email and text in one account instead of SMS alone.
Klaviyo fixes the biggest gap in Postscript: there is no email channel. Email, SMS, MMS, WhatsApp and RCS all run against the same customer profile, so one flow can email a customer, then text them if they do not open it. The free plan covers 250 profiles, 500 emails and $5 of mobile messages a month, which is a real free start that Postscript does not offer.
The catch is the cost structure. SMS is billed per message at about $0.01 per US toll-free text plus carrier fees, on top of the email plan that starts at $20 a month. A store that sends mostly text will pay more per message than on Postscript Growth, so price your real volume before switching.
What we like
Email, SMS, WhatsApp, RCS and push on one profile.
Free plan covers 250 profiles with $5 of mobile messages.
Flows can switch channels based on customer behavior.
Watch out for
SMS costs extra per message on top of the email plan.
Prices rise with profile count on every tier.
The SMS inbox is thinner than a dedicated texting tool.
Switch if: Switch if your store outgrew Postscript and wants AI replies with a managed team.
Attentive is the step up from Postscript for a Shopify brand with serious volume. Its AI tools draft replies, tune send times and run conversational journeys that answer common questions before a human steps in, and the two-tap signup unit collects consent fast on mobile. White-glove onboarding sets the program up for you.
The catch is the price and the process. Attentive publishes no pricing, so every deal is a negotiated quote that usually starts with an annual commitment and a quarterly minimum. A store doing Postscript-level volume will not see a saving here; this is a move for scale and service, not for a lower bill.
What we like
AI replies and send-time tuning built for ecommerce.
Two-tap mobile signup grows lists fast.
White-glove onboarding and a dedicated team.

No published pricing; every price is a negotiated quote.

SimpleTexting is the best Postscript alternative for a store that is leaving Shopify or never used it. It works on any platform, and every plan includes a shared inbox, three user seats, unlimited contacts and unlimited keywords, so the team can answer customers without tripping over each other. Polls and contests give people a reason to text you first.
The catch is the credit model. The entry plan is $29 a month for 500 credits with a toll-free number, or $39 with a local number, and each MMS costs three credits. A store used to Postscript per-message billing will need to relearn the cost math, and carrier fees pass through on top.
What we like
Works on any store platform, not just Shopify.
Shared inbox with three seats on every plan.
Polls, contests and text-to-win campaigns built in.
Watch out for
Entry plan is $29 a month with a toll-free number, $39 with a local number.

Omnisend is the best free Postscript alternative for a small store. The free plan covers 250 contacts and 500 emails a month with automation included, and the same account handles email, SMS and push once you pay. Pre-built welcome and abandoned-cart flows switch on the same day you connect your store, which is the same job Postscript does for Shopify.
The catch is that SMS is a paid-tier channel. New subscribers cannot buy SMS on the Standard plan at $16 a month; SMS needs Pro at $59 a month, with rates from $0.007 per message. The free plan also caps SMS at 60 credits, so it is a trial of the channel, not a working texting plan.
What we like
Free plan with automation for 250 contacts and 500 emails.
Email, SMS and push in one account for stores.
Pre-built welcome and cart flows ready on day one.
Switch if: Switch if you want a flat monthly price with no minimum spend.
Textedly is the simplest Postscript alternative to price. Every plan includes every feature, and only the message volume changes, so there is no minimum spend and no per-message surprise. Basic is $29 a month for 500 messages, incoming messages are free, and two-way chats, drip campaigns and text-to-pay all work from the entry tier.
The catch is the surcharge and the trial. An $8 monthly telecom surcharge applies to paid plans, so Basic costs $37 a month in practice. There is no free plan, only a trial with 50 messages and one keyword, and the Shopify link runs through a standard integration rather than the deep native segments Postscript offers.
What we like
Every feature on every plan, including text-to-pay.
No monthly minimum spend, unlike Postscript.
Free incoming messages with toll-free and 10DLC numbers.
Watch out for
No free plan, only a trial with 50 messages.

Switch if: Switch if you want the lowest monthly bill and a simple setup.
EZ Texting is the cheapest flat-rate Postscript alternative. Launch is $25 a month, or $20 billed annually, for 500 credits, and setup takes minutes: import contacts, pick a keyword and send. Two-way messaging and MMS work from the entry plan, and the interface is simple enough for a store owner with no marketing team.
The catch is the seat limit. Each plan includes only one user, extra seats cost $10 a month each, and Launch carries a $5 monthly telecom fee. Team texting only arrives on Scale at $125 a month, and the Shopify connection is thinner than the native segments Postscript builds on.
What we like
Lowest monthly plan price in this list at $25 a month.
Fast setup with two-way messaging on every plan.
Simple interface that a store owner can run alone.
Watch out for
Only one user seat per plan; extra seats cost $10 a month.
Switch if: Switch if carrier compliance worries you more than Shopify depth.
SlickText is the careful Postscript alternative. Its opt-in tools, keyword handling and list management follow carrier rules closely, and every plan includes all features, unlimited users, unlimited contacts and free incoming messages. Plans start at $29 a month for 500 credits, with two months free on annual billing.
The catch is cost at the edges. Rich messaging carries setup and annual fees, and the most useful automation sits above the entry tier. Short codes need at least the $319 plan, and the Shopify link is a standard integration, so a store that leans on deep Shopify segments will miss Postscript.
What we like
Compliance-first opt-in and keyword handling.
Unlimited users and contacts on every plan.
All features included, with two months free annually.

Switch if: Switch if you have a developer and want the lowest per-message rate.
Twilio is the Postscript alternative for a team that wants to build its own flow. There is no platform fee and no monthly minimum: US SMS costs $0.0083 per segment plus carrier fees, and you pay only for what you send. That beats Postscript per-message rates at any volume, and the API covers SMS, MMS, WhatsApp and voice.
The catch is that Twilio is a developer platform with no inbox, no campaigns and no automation of its own. A store needs a developer to build the sending flow and the reply view, plus number rental at $1.15 a month for a long code and $2.15 for toll-free, and A2P 10DLC campaign fees on top.
What we like
No platform fee and no monthly minimum spend.
$0.0083 per US SMS segment, the lowest rate here.
API covers SMS, MMS, WhatsApp and voice.
Watch out for
No inbox, campaigns or automation built in.
Needs a developer to build the sending flow.
Number rental and 10DLC fees sit on top of message rates.

What is the best Postscript alternative?
Klaviyo is the best Postscript alternative for most stores in 2026 because it adds email, SMS and push on one profile with a free plan for 250 profiles. Attentive is the best pick for a large Shopify brand that wants AI replies, and SimpleTexting is the best pick for a store leaving Shopify. Pick by the reason you are leaving, since the best replacement depends on whether price, platform or email is the gap.
Is there a free Postscript alternative?
Yes, two tools in this list have a free plan. Klaviyo covers 250 profiles, 500 emails and $5 of mobile messages a month, and Omnisend covers 250 contacts and 500 emails, with only a one-time $1 SMS credit (about 66 US messages) and no SMS plan for new accounts. Neither free plan runs a real texting program on its own, and Omnisend needs Pro at $59 a month for ongoing SMS. The other six tools offer a free trial only, and Postscript itself starts at $0 a month with a $49 minimum spend.
Which Postscript alternatives work best for stores outside Shopify?
SimpleTexting, SlickText and Omnisend work best for stores outside Shopify, since none of them is tied to one store platform. SimpleTexting is the best all-round pick, with a shared inbox and three seats on every plan. Omnisend is the best free starting point, and SlickText is the best pick for a team that wants compliance handled carefully. Klaviyo also works on any platform, with email and text on one profile.
Why do stores leave Postscript?
Stores leave Postscript for four reasons: it works only with Shopify, the $49 monthly minimum spend bills in quiet months, per-message costs climb with volume, and it has no email channel. A store on another platform leaves for the first reason, a small store leaves for the second, and a store that wants one account for email and text leaves for the fourth.
How should I run a Postscript alternatives comparison?
Run a Postscript alternatives comparison on your real monthly volume, not on the headline price. Price each tool at your message count, add carrier fees and number rental, and check whether the free plan covers your list. Then check the Shopify depth you would lose, since Postscript segments on live Shopify data that a general tool cannot match.
Frequently asked questions
What is the best Postscript alternative for Shopify?
Klaviyo is the best Postscript alternative for a Shopify store that wants email added, with one profile for email, SMS and push. Attentive is the best pick for a large Shopify brand that wants AI replies. Postscript itself is hard to beat on Shopify-native segments, so switch only if price, email or scale is the reason.
Is Klaviyo better than Postscript?
Klaviyo is better than Postscript if you want email and text in one account, since Postscript has no email channel. Postscript is better if SMS is the whole program and you want Shopify-native segments with per-message billing. Klaviyo SMS costs about $0.01 per US toll-free text on top of the $20 email plan, while Postscript Starter is $0 a month with a $49 minimum.
Is there a cheaper Postscript alternative?
Yes. Textedly is $29 a month for 500 messages with every feature included, and EZ Texting is $25 a month for 500 credits. Twilio is cheaper per message at $0.0083 per US SMS segment with no platform fee, but it needs a developer. All three beat Postscript for a small list that sends under the $49 minimum.
Does Postscript have a free plan?
No. Postscript has no free plan, only a 30-day trial. Starter is $0 a month in platform fees, but it carries a $49 monthly minimum spend on messages and carrier fees, so the first bill is at least $49 in a sending month. Klaviyo and Omnisend are the free-plan picks in this list.
Which Postscript alternative has the best free plan?
Klaviyo has the best free plan in this list, covering 250 profiles, 500 emails and $5 of mobile messages a month. Omnisend is second, with 250 contacts and 500 emails a month, but no SMS on its free plan. Both free plans are small, so a store texting hundreds of customers weekly needs a paid plan within weeks.
Can I move my list from Postscript to Klaviyo?
Yes. Export your SMS subscribers from Postscript, including opt-in records, and import them into Klaviyo as profiles with SMS consent. Keep the opt-in evidence, since carriers and regulators expect proof of consent. Klaviyo also offers migration help on paid plans, so ask support before you move a large list.
Is Twilio a good Postscript alternative?
Twilio is a good Postscript alternative only if you have a developer. It charges $0.0083 per US SMS segment with no platform fee and no minimum spend, which beats Postscript rates. But Twilio ships no inbox, no campaigns and no automation, so a store without a developer gets a cheaper bill and no tool to send with.
