QUICK ANSWER
Klaviyo is the best SMS marketing software for small business in 2026 because it pairs SMS with email in one account and starts free for up to 250 profiles. Omnisend is the cheapest paid pick at $16 a month, and SimpleTexting is the best pick if you only need SMS.
Key takeaways
3 of 8 shortlisted tools have a free plan; lowest listed paid start: $9 a month (Brevo) (Nov 2026).
Klaviyo ranks first because it pairs SMS with email in one account and starts free for up to 250 profiles.
Omnisend is the cheapest paid pick at $16 a month, but SMS needs the Pro plan at $59 a month.
SimpleTexting and SlickText include every feature on every plan, so the entry tier is not stripped down.
Carrier fees and telecom surcharges sit on top of every plan price, so price your real message volume before you pick.
The best SMS marketing software for small business keeps the monthly bill low while your list is small, sets up in a day, and gives you a human to call when a campaign stalls. Every tool below was priced at 500 messages a month and judged on setup time and included support.
Klaviyo suits a small business that wants one account for email and text. The free plan covers 250 profiles, 500 emails and $5 of mobile messages a month, so a new shop can run welcome texts and abandoned-cart reminders before paying anything. The paid Email plan starts at $20 a month for 251 to 500 profiles, and Email plus SMS starts at $35 a month, with SMS billed as credits on top.
The catch is that the bill climbs with your list. Klaviyo charges by active profiles, so every new subscriber raises the price, and SMS credits cost extra on every tier. Email support on the free plan also ends after 60 days. A shop with a fast-growing list should model the price at 1,000 and 5,000 profiles before committing.
What we like

Email and SMS share one list, so flows can switch channels.

Omnisend is the cheapest paid pick for a small business that wants email and SMS together. Standard starts at $16 a month for up to 500 contacts with 6,000 emails, and the free plan covers 250 contacts and 500 emails a month. Every plan includes automation, segmentation and A/B testing, so the entry tier is not stripped of the tools that make SMS work.
The catch is that SMS is not a Standard feature for new accounts. Plans started after May 4, 2026 need Pro at $59 a month to buy SMS credits, which start at $0.007 per message in the US. A business that only wants SMS will pay $59 a month here, while a business that wants email plus SMS gets a fair deal.
What we like
Standard starts at $16 a month for up to 500 contacts.
Automation, segmentation and A/B testing on every plan.
Free plan covers 250 contacts and 500 emails a month.

SimpleTexting is the best pick for a small business that only needs SMS and wants no surprises. It starts at $39 a month for 500 credits with a local number included, and every feature ships on every plan: automations, API access, AI writing help and unlimited keywords. Three user seats are included, and unused credits roll over for one month.
The catch is the price for a small sender. At $39 a month, it costs more than EZ Texting or Textedly for the same 500 messages, and extra credits cost 5.5 cents each. Carrier fees of about $0.0025 per message sit on top, plus a $4 one-time carrier registration fee. A business sending under 500 texts a month pays more here than on a pay-as-you-go tool.
What we like
Every feature ships on every plan, with no tier gating.
Three user seats included at no extra cost.
Unused credits roll over for one month.
Watch out for
At $39 a month, it costs more than rivals for 500 messages.

EZ Texting is the cheapest monthly SMS plan in this list. Launch costs $25 a month, or $20 a month billed annually, for 500 credits with a local number included. The setup flow is short, the interface is plain, and every plan includes the core tools a small business needs: keywords, scheduled sends and two-way texting.
The catch is the fees around the headline price. Launch adds a $5 a month telecom fee, MMS costs 3 credits per message, and extra users cost $10 a month each. A business that sends picture messages will burn through 500 credits fast. Check the real monthly total with the telecom fee included before you compare it with SlickText at $29 a month.
What we like
Launch at $25 a month is the cheapest monthly plan here.
Setup takes under a day with a local number included.
Plain interface that a non-technical owner can run.
Textedly suits a small business that sends a steady number of texts each month and wants one flat price. Basic costs $29 a month for 500 messages, or 600 messages billed annually, and every plan includes all features: two-way texting, MMS, text-to-pay, review requests and AI writing help. There is no contract, and inbound messages are always free.
The catch is the surcharge. Every account pays an $8 a month telecom surcharge, so the real entry cost is $37 a month, not $29. Extra texts cost $30 for 500, and extra teammates cost $10 a month each. There is also no free plan, only a 14-day trial with 50 messages, so you cannot run a small list free here.
What we like
All features on every plan, priced by volume only.
No contract, with month-to-month or annual billing.
Inbound messages are always free.
Watch out for
An $8 a month telecom surcharge lifts the real cost to $37.
No free plan, only a 14-day trial with 50 messages.
SlickText is the best pick for a small business that wants flexible credits and a growing team. It starts at $29 a month for 500 credits, and every plan includes unlimited users, unlimited contacts, rollover credits, all automation features and every integration. Unused credits carry to next month, so a quiet month is not wasted money.
The catch is that SlickText is SMS-only, with no email channel in the same account. MMS costs 3 credits per message, and carrier fees sit on top of the plan price. A business that also wants email will need a second tool, which wipes out the savings from the low plan price.
What we like
Unused credits roll over to the next month.
Unlimited users and contacts on every plan.
Every feature and integration ships on the $29 tier.
Brevo suits a small business that sends email most days and texts only now and then. Starter costs $9 a month for 5,000 emails, and the free plan sends 300 emails a day. SMS credits are sold separately on a pay-as-you-go basis, so a business that texts rarely pays only for the messages it sends, with no SMS subscription to carry.
The catch is that SMS is a side channel here, not the main product. The SMS tools are thinner than on a dedicated SMS platform, with fewer templates and no SMS-first automation library. Automation and A/B testing also need Standard at $18 a month, and the Brevo logo stays on Starter emails unless you pay for removal.
What we like
Lowest paid start in this list at $9 a month.
Free plan sends 300 emails a day.
SMS credits are pay-as-you-go, so rare senders pay little.
Watch out for
SMS tools are thinner than on a dedicated SMS platform.
Automation and A/B testing need Standard at $18 a month.
Starter keeps Brevo branding unless you pay for removal.

TextMagic is the best pick for a small business that texts rarely and wants no monthly bill. It charges $0.049 per SMS in the US on a pay-as-you-go basis, with credits that never expire, so a business that sends 100 texts a month pays about $5. It covers 190 countries, which suits businesses with customers abroad, and it includes two-way chat and scheduling.
The catch is the number rent. A virtual number costs $10 a month, and 10DLC campaign registration costs another $10 a month, so the real floor is about $20 a month before you send a single text. The per-message rate is also high: at 500 texts a month, TextMagic costs about $25, the same as EZ Texting, with fewer marketing features.
What we like
No monthly fee, and credits never expire.
Covers 190 countries for international texting.
Two-way chat and scheduling are included.
Watch out for
A number costs $10 a month and 10DLC registration $10 a month.
At $0.049 per SMS, heavy senders pay more than on a plan.
Fewer marketing templates than the SMS-first tools.

What we looked at
Price at small-business scale
40%
We priced each tool at 500 messages a month and noted the free plan limits, since a small list is where the cost gap is widest.
Setup time
30%
We favored tools a small team can launch in a day, with a number, keywords and templates included rather than added on.
Included support
30%
We checked which support channels come with the entry plan, since a small business rarely has a specialist to call on.
