QUICK ANSWER
Klaviyo is the best Omnisend alternative in 2026 for most stores because it covers email, SMS and push on one profile with a free plan for 250 profiles. Postscript is the best pick for a Shopify store that wants SMS-led revenue, and SimpleTexting is the best pick for a team that wants a dedicated texting inbox.
Key takeaways
1 of 8 shortlisted tools has a free plan, and the lowest listed paid start is $0.0083 per SMS segment (Twilio) (Nov 2026).
Klaviyo ranks first because it matches Omnisend on channels and beats it on SMS access.
Omnisend locks SMS behind Pro at $59 a month for new subscribers, which is the main reason stores leave.
Klaviyo is the only tool here with a free plan.
Postscript and Attentive are the strongest picks for stores that send SMS as their main channel.
Omnisend is a good email and SMS tool for small stores, but its SMS pricing pushes some stores to look elsewhere. New subscribers cannot buy SMS on the Standard plan at $16 a month; SMS needs Pro at $59 a month, and the free plan caps SMS at 60 credits. This guide compares eight Omnisend alternatives on price, free plans and fit, with a clear reason to switch for each one.
This guide sits under our SMS marketing pillar, which compares the full category. If you want the broader shortlist first, our guide to the best SMS marketing software for small business covers the same tools without the Omnisend focus.
Switch if: Switch if you want SMS without paying for the top tier.
Klaviyo is the closest Omnisend alternative and the easiest switch. 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, and SMS is available on every paid plan, unlike Omnisend where new subscribers need Pro.
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 than Omnisend Pro at high volume, and the SMS inbox is thinner than a dedicated texting tool.
What we like
Email, SMS, WhatsApp, RCS and push on one profile.
Free plan covers 250 profiles with $5 of mobile messages.
SMS available on every paid plan, not just the top tier.

Switch if: Switch if SMS is your main channel and you run a Shopify store.
Postscript is the Omnisend alternative for a Shopify store that wants SMS to lead. It segments on live Shopify data such as tags, purchases and browse behavior, and its conversational inbox lets staff or AI agents close sales inside the thread. Starter is $0 a month in platform fees with a $49 monthly minimum spend, and rates run about $0.009 per SMS.
The catch is the narrow fit and the missing email. Postscript works only with Shopify, so a store on any other platform cannot use it at all, and it has no email channel, so a store that wants one account for both channels still needs a second tool. The $49 minimum also bills in quiet months.
What we like
Shopify-native segments on tags, orders and browsing.
Conversational inbox with AI and human sales agents.
SMS-first pricing with no platform fee on Starter.
Watch out for
Shopify only; no other store platform is supported.
No email channel, so email needs a second tool.
The $49 monthly minimum bills even in quiet months.
Switch if: Switch if your store outgrew Omnisend and wants AI replies with a managed team.
Attentive is the step up from Omnisend for a large ecommerce brand. 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 on Omnisend Pro at $59 a month 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.
Annual contracts with quarterly minimums are the norm.

Switch if: Switch if you want a real SMS inbox instead of SMS as an add-on.
SimpleTexting is the Omnisend alternative for a store that wants texting to have its own home. Every plan includes a shared inbox, three user seats, unlimited contacts and unlimited keywords, plus polls, contests and text-to-win campaigns that Omnisend lacks. The entry plan is $29 a month for 500 credits with a toll-free number.
The catch is the missing email. SimpleTexting is SMS only, so a store that wants email in the same account still needs a second tool. The $29 entry covers a toll-free number; a local number costs $39 a month, and each MMS costs three credits, so photo messages burn the allowance fast.
What we like
Shared inbox with three seats, which Omnisend lacks.
Polls, contests and text-to-win campaigns built in.
Unlimited contacts and keywords on every plan.
Watch out for
SMS only; email needs a second tool.
Local number costs $39 a month, not $29.
MMS costs three credits, so photo messages burn the allowance.
Switch if: Switch if you want SMS on the entry plan, not the top tier.
Textedly is the simplest Omnisend alternative to price. Every plan includes every feature, and only the message volume changes, so drip campaigns, two-way chats, text-to-pay and review requests all work from Basic at $29 a month for 500 messages. Incoming messages are free, and the account comes with a toll-free number and a 10DLC number.
The catch is the surcharge and the missing email. 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 Textedly is SMS only, so a store that wants email in the same account still needs a second tool.
What we like
Every feature on every plan, including text-to-pay.
Free incoming messages with toll-free and 10DLC numbers.
No top-tier gate on SMS, unlike Omnisend.
Watch out for
No free plan, only a trial with 50 messages.

Switch if: Switch if you want the lowest monthly bill for SMS alone.
EZ Texting is the cheapest Omnisend alternative for a store that wants SMS only. 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 and the missing email. 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 EZ Texting is SMS only, so email still needs a second tool.
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 bundled email.
SlickText is the careful Omnisend 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 and the missing email. 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 SlickText is SMS only, so a store that wants email in the same account still needs a second tool.
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 Omnisend 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 Omnisend Pro SMS 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, no email and no automation of its own. A team 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 is the best Omnisend alternative?
Klaviyo is the best Omnisend alternative for most stores in 2026 because it covers email, SMS and push on one profile with a free plan for 250 profiles, and SMS works on every paid plan. Postscript is the best pick for a Shopify store that wants SMS-led revenue, and SimpleTexting is the best pick for a team that wants a dedicated texting inbox. Pick by the reason you are leaving, since the best replacement depends on whether SMS access, price or email is the gap.
Is there a free Omnisend alternative?
Yes, one tool in this list has a free plan. Klaviyo covers 250 profiles, 500 emails and $5 of mobile messages a month. The other seven tools offer a free trial only. Omnisend itself has a free plan with 250 contacts and 500 emails a month, but SMS needs Pro at $59 a month.
Which Omnisend alternatives include SMS on the entry plan?
Klaviyo, SimpleTexting, Textedly, EZ Texting, SlickText and Postscript all include SMS on their entry plans. Klaviyo is the best pick for a store that wants email too, since SMS works on every paid plan. SimpleTexting is the best pick for a dedicated inbox, and Textedly is the best pick for a flat price with every feature included.
Why do stores leave Omnisend?
Stores leave Omnisend for three reasons: SMS is locked behind Pro at $59 a month for new subscribers, prices rise steeply as contact count grows, and the SMS inbox is thinner than a dedicated texting tool. A small store leaves for the first reason, a growing store leaves for the second, and a team that answers many customer replies leaves for the third.
How should I run an Omnisend alternatives comparison?
Run an Omnisend 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 compare the all-in cost against Omnisend Pro at $59 a month. Then check whether SMS works on the entry plan, since that gate is the main reason stores leave.
