8 Best Cheap SMS Marketing Software in 2026: Top Picks Compared

Twilio is the cheapest way to send a text in the US. It charges $0.0083 per outbound or inbound SMS segment, with no monthly fee and volume discounts at scale. At 500 messages a month, the message fees come to about $4.15, plus carrier fees of $0.0025 to $0.0045 per message and a $1.15 a month number rent. No monthly plan in this list comes close on raw price.

The catch is that Twilio is an API, not a marketing tool. It has no campaign builder, no list management, no opt-out handling and no templates, so you build all of that yourself or pay another tool to do it. A2P 10DLC registration and compliance are also your job. A team without a developer will spend more on build time than it saves on message fees.

TextMagic is the cheapest no-code way to send texts. 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, and it includes two-way chat, scheduling and email-to-SMS, which covers order updates and customer questions.

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 text. The per-message rate is also high: at 500 texts a month, TextMagic costs about $25 in messages, the same as EZ Texting, with fewer marketing features.

Brevo is the cheapest paid start in this list at $9 a month, and it suits a sender who texts rarely. Starter costs $9 a month for 5,000 emails, the free plan sends 300 emails a day, and SMS credits are sold separately on a pay-as-you-go basis. A business that sends email most days and texts only for a sale or an alert pays almost nothing extra for SMS.

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 need Standard at $18 a month, and the Brevo logo stays on Starter emails unless you pay for removal. It is cheap because SMS is not the focus.

Omnisend is the cheapest paid plan that bundles email with SMS. 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 campaigns 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 sender who only wants SMS will pay $59 a month here, while a sender who wants email plus SMS gets a fair deal at the Pro price.

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 keywords, scheduled sends and two-way texting, so a small sender can launch a first campaign in a day.

The catch is the fees around the headline price. Launch adds a $5 a month telecom fee, so the real cost is $30 a month, MMS costs 3 credits per message, and extra users cost $10 a month each. A sender that sends picture messages will burn through 500 credits fast. At $30 a month all-in, it ties SlickText at $29 a month, so compare the extras, not the headline.

Textedly suits a sender who 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, which makes it the priciest $29 plan in this list. 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.

Sakari suits a sales team that already runs a CRM and wants texts tied to deals. It starts at $25 a month with about $0.0304 per US segment, and it links natively to HubSpot, Pipedrive and ActiveCampaign, so a deal stage change or a new contact can trigger a text without a third-party app. Unlimited users and contacts sit on every plan, and unused credits roll over for 90 days.

The catch is the per-segment rate. At about $0.0304 per segment, Sakari costs three to four times what Twilio charges per message, so a high-volume sender pays more here than on a cheaper plan. MMS costs $0.02 extra per message and works only in the US and Canada, and the per-segment rate varies by country, so international sends need their own math.

SlickText is the best pick for a sender who 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 banks credit for a busy one.

The catch is that SlickText is SMS-only, with no email channel in the same account, and carrier fees sit on top of the plan price. MMS costs 3 credits per message, so a sender that sends picture messages will burn through 500 credits fast. At $29 a month all-in, it ties EZ Texting once the telecom fee is added, so pick by features, not price.
