Best SMS Marketing Tools for 2026: Compare 9 Platforms

October 9, 2026

mysaasjourney

Choosing the best SMS marketing tool depends on what you want to send, who you want to reach, and how much control you need over customer data. An ecommerce brand sending abandoned-cart reminders has different needs from a local business promoting events or a marketing team coordinating SMS with email and CRM workflows.

Our recommendation is to start with your use case, not the longest feature list. Ecommerce brands should compare Klaviyo, Postscript, and Omnisend first. Businesses that need straightforward promotional texting should consider SimpleTexting, SlickText, or EZ Texting. Teams that want SMS within a wider marketing system may prefer Brevo, while larger brands can evaluate Attentive.

This guide compares nine SMS marketing platforms using official product documentation, pricing pages, and published product information. Pricing was checked on October 9, 2026. This is a desk-based comparison, not a hands-on product test, so recommendations reflect documented capabilities and use-case fit rather than original performance testing.

How we evaluated these SMS marketing platforms

We considered five buyer-focused criteria:

Use-case fit: whether the product suits ecommerce, general business texting, or enterprise messaging.
Campaign and automation capabilities: support for scheduled campaigns, triggered messages, segmentation, and workflows.
Pricing clarity: how clearly the vendor explains subscriptions, credits, usage rates, and extra fees.
Integrations and customer data: whether the product connects SMS activity with ecommerce, CRM, and marketing workflows.
Compliance and operations: whether consent, opt-outs, sender setup, and regional messaging requirements are addressed.

Our research uses vendor documentation and pricing pages available on October 9, 2026. We have not independently tested deliverability, campaign performance, support response times, or revenue attribution.

1. Klaviyo: Best for ecommerce personalization

Official links: SMS marketing | Pricing

Klaviyo is a strong candidate for ecommerce businesses that want SMS to use the same customer information and marketing logic as their other campaigns. Marketers can use customer behavior and segments to tailor messages instead of treating every subscriber as a generic list entry.

Its SMS capabilities include one-time campaigns, automated flows, audience targeting, multimedia messaging, performance reporting, and tools for managing consent and opt-outs. These features can support messages triggered by a signup, purchase, or abandoned shopping session.

Key strengths

Connects SMS campaigns to customer segmentation and marketing automation.
Supports scheduled campaigns and behavior-triggered messages.
Provides campaign analytics and message testing features.
Includes consent and opt-out management tools.

Limitations

It may be more than a small organization needs for occasional announcements.
SMS pricing depends on account rates and recipient region.
Buyers should check the exact plan, allowances, and current rates before estimating monthly costs.

Klaviyo moved mobile messaging to a dollar-based, per-message pricing model beginning July 13, 2026. The vendor advises customers to review their account-specific rates. See the official pricing change documentation.

Pricing: Plan and message charges depend on account configuration and usage. Consult the official pricing page for the current offer.

Verdict: Shortlist Klaviyo if your store already relies on customer segmentation and automated ecommerce marketing. If you only need a weekly promotional text, compare a dedicated mass-texting platform before paying for a broader system.

2. Postscript: Best for Shopify-focused SMS marketing

Official links: Postscript | Pricing

Postscript focuses on ecommerce messaging, particularly SMS programs built around Shopify customer data. Its product combines campaign creation, automation, subscriber acquisition, segmentation, reporting, and reply management.

Key strengths

Ecommerce-focused automation templates.
Subscriber acquisition tools, including opt-in forms and keywords.
Segmentation using Shopify data and supported integrations.
Reporting for subscriber growth and messaging performance.
Reply management for subscriber conversations.

Limitations

Its specialized focus may be unnecessary outside ecommerce.
Message charges and carrier fees are additional considerations.
Higher tiers cost more and unlock capabilities such as enhanced analytics and API access.

Pricing checked October 9, 2026: The pricing page lists Starter at $0 per month with a $49 monthly minimum spend, Growth at $100 per month, Professional at $500 per month, and custom Enterprise pricing. Published US messaging rates are $0.009 per SMS for Starter, $0.008 for Growth, and $0.007 for Professional. MMS charges and carrier fees are additional. Confirm rates for your destination markets.

Verdict: Postscript belongs on the shortlist for Shopify stores that treat SMS as a retention channel. Businesses with basic texting needs should compare its minimum spend and feature tiers against simpler alternatives.

3. Attentive: Best for larger messaging programs

Official links: Attentive | Pricing

Attentive is designed for brands that need more than a standalone SMS campaign tool. Its platform supports SMS, email, RCS, and push messaging, with shared workflows and customer profiles intended to coordinate campaigns across channels.

Key strengths

Multiple messaging channels in one platform.
Cross-channel journeys and campaign testing.
A published library of pre-built integrations.
Dedicated support and onboarding options.
Pricing tailored to selected channels and usage.

Limitations

There is no single public monthly starting price for every customer.
Costs depend on subscriber count, message volume, channels, and selected products.
Smaller businesses may not need the broader platform or support model.

Pricing: Custom and usage-based. Attentive says pricing depends on messaging volume, subscriber count, channels, and selected products. Request a quote that separates base fees, message rates, carrier fees, minimum commitments, and optional products.

Verdict: Consider Attentive if SMS is part of a larger multi-channel marketing operation. Smaller teams should compare the value of its broader capabilities against simpler subscriptions.

4. Omnisend: Best for ecommerce email and SMS workflows

Official links: Omnisend | Pricing

Omnisend is worth considering if you want to coordinate email and SMS campaigns for an ecommerce store without adopting a separate SMS-only platform. It combines ecommerce marketing automation, audience segmentation, email campaigns, push notifications, and SMS messaging.

Key strengths

Combines email and SMS within ecommerce workflows.
Supports automated campaigns and audience segmentation.
Has a free plan for email marketing with sending limits.
Offers volume-based SMS pricing for eligible subscriptions.

Limitations

SMS access depends on the current subscription structure.
SMS credits are separate from the Pro subscription for new subscribers under the model introduced in May 2026.
Businesses should confirm both the base plan and expected message cost.

Pricing checked October 9, 2026: Free is $0 per month, Standard starts at $16 per month, and Pro starts at $59 per month. Under current terms, SMS is not available to new Free or Standard subscribers; eligible new Pro subscribers purchase SMS credits separately. Omnisend’s documentation says its legacy Pro SMS arrangement is scheduled to migrate to the current model on October 26, 2026. Review the official plan and pricing documentation.

Verdict: Omnisend is a sensible option for ecommerce teams that want email and SMS in the same marketing system. Compare the total cost, including the Pro subscription and SMS credits, rather than judging it by the email plan price alone.

5. SimpleTexting: Best for straightforward business texting

Official links: SimpleTexting | Pricing

SimpleTexting suits organizations that need to send announcements, promotions, reminders, and other business text messages without adopting a specialist ecommerce marketing platform. Its credit-based pricing can help estimate campaign budgets, provided you account for message volume, number costs, and extra fees.

Key strengths

A pricing calculator based on message volume and number requirements.
A practical fit for general business texting.
Options for local, toll-free, and dedicated short-code numbers.
A free trial is advertised on the pricing page.

Limitations

Message credits and phone-number charges can increase the base cost.
Extra credits are billed separately.
Businesses needing advanced ecommerce personalization should compare its workflows with Klaviyo or Postscript.

Pricing example checked October 9, 2026: The pricing calculator displays an estimated monthly cost of $39 for 500 credits and a local number. The example includes $29 for credits and $10 for the local number, plus a one-time $4 carrier registration charge and additional carrier fees. Your estimate depends on the configuration selected.

Verdict: SimpleTexting is worth a look for small businesses, nonprofits, service providers, and marketing teams that need practical mass-texting capabilities. Use the pricing calculator with your expected recipients and campaigns before choosing a plan.

6. SlickText: Best for promotional campaigns and list growth

Official links: SlickText | Pricing

SlickText focuses on SMS campaigns and subscriber growth. Its pricing page lists unlimited contacts, rollover credits, a sending number, and campaign workflows, with credit allowances that vary by plan.

Key strengths

Published monthly plans with clear credit allowances.
Unlimited contacts on listed paid plans.
Rollover of unused credits for a defined period.
Campaign workflows and integrations across paid plans.
Phone, chat, and email support listed on the pricing page.

Limitations

The vendor says its SMS service supports the United States and Canada.
Carrier fees apply on top of plan prices.
MMS uses more credits than standard SMS, so media-heavy campaigns can consume allowances faster.

Pricing checked October 9, 2026: Published examples include $29 per month for 500 credits, $49 for 1,000 credits, $79 for 2,000 credits, and $129 for 3,500 credits. Higher-volume and custom plans are available. One credit corresponds to one standard SMS segment sent to one subscriber; MMS consumes more credits. See the official pricing page.

Verdict: SlickText is a candidate for US and Canadian businesses that want a dedicated campaign tool with public pricing. It is less suitable if you need messaging coverage beyond those markets or specialized ecommerce customer-data workflows.

7. Textmagic: Best for usage-based business messaging

Official links: Textmagic | Pricing

Textmagic is worth evaluating if you prefer usage-based messaging instead of committing to a large monthly marketing platform. It sells prepaid credits and publishes destination-specific pricing, which can suit teams with variable campaign volume or occasional business messaging needs.

Key strengths

Pay-as-you-go messaging credits.
Pricing that can be checked by destination country and volume.
Options for local or toll-free numbers in supported markets.
Incoming SMS is listed as free in published pricing information.
MMS and other communication options are available at separate rates.

Limitations

You need to budget for a texting number or sender registration where required.
Longer or Unicode messages may consume multiple message parts.
Frequent high-volume senders should compare usage rates with subscription plans.

Pricing checked October 9, 2026: The US pricing page displays an example of $0.049 per outbound SMS part. It also lists a $10 monthly fee for a local or toll-free texting number in the US or Canada, with MMS priced separately. Prices and number types depend on destination and setup.

Verdict: Textmagic is a reasonable candidate for teams that value flexible usage-based pricing. Estimate message volume and number costs over several months before deciding whether pay-as-you-go will remain economical.

8. Brevo: Best for SMS alongside broader marketing

Official links: Brevo | Pricing

Brevo combines email marketing, customer communication, and CRM-related tools. SMS credits can be purchased as an add-on, allowing a team to evaluate text messaging alongside broader marketing activities rather than maintaining a separate system.

Key strengths

SMS credits can be purchased separately from the main plan.
Prepaid credits are available as an add-on.
According to Brevo’s documentation, credit packs start at 100 and do not expire.
Can suit teams that want SMS and email within a wider marketing stack.

Limitations

There is no single universal SMS rate for all recipient countries.
Prepaid credits are non-refundable.
Credit use depends on destination and message length.

Pricing: Brevo documents prepaid SMS credit purchases as a one-time purchase, with costs calculated according to recipient country and message requirements. Check the current estimate in your account or on the official add-ons documentation.

Verdict: Brevo deserves a place on the shortlist if you want to add SMS to broader marketing activities. Avoid comparing it by one headline SMS price, because your recipient mix determines the cost.

9. EZ Texting: Best for group texting and promotions

Official links: EZ Texting | Pricing

EZ Texting is designed for businesses that need to reach groups of customers with text campaigns. It can be relevant for local businesses, event organizers, service providers, and organizations sending promotions or updates to opted-in contacts.

The vendor’s published features include contact lists and segments, mass texting, message credits, and integrations with tools such as Salesforce, HubSpot, Squarespace, Zapier, and Zendesk.

Key strengths

Public monthly and annual plan pricing.
Plans organized around contact volume and messaging needs.
SMS and MMS credit accounting.
Integrations with selected CRM, website, and workflow tools.
A free trial is advertised in the vendor’s FAQ.

Limitations

Credits are limited by plan, and extra usage is billed separately.
MMS messages consume more credits than standard SMS messages.
Enterprise messaging and dedicated short codes can cost more than entry plans.

Pricing checked October 9, 2026: The published Launch plan starts at $25 per month on monthly billing or $20 per month with annual billing. Boost starts at $75 monthly or $60 with annual billing, while Scale starts at $125 monthly or $100 with annual billing. The page lists 500 monthly credits on these plans and separate overage rates. Confirm checkout terms and allowances on the official pricing page.

Verdict: EZ Texting is a candidate for businesses that want a dedicated group-texting tool with public plan options. Compare its credits, number type, and overage costs with SimpleTexting and SlickText.

How much does SMS marketing software cost?

SMS marketing software does not have one standard price. Some vendors charge a monthly subscription plus message usage, while others use prepaid credits or custom contracts.

Pricing model	How it works	Best suited to
Subscription plus usage	Pay a monthly plan fee and messaging charges	Regular campaigns and growing programs
Credit-based	Buy a monthly allowance of message credits	Businesses that want a defined allowance
Pay-as-you-go	Purchase credits or pay for usage as needed	Variable or occasional messaging
Custom contract	Negotiate based on volume and selected products	Larger messaging programs

The base subscription is only one part of the budget. Message volume, recipient country, message length, MMS, sending-number requirements, and carrier fees can change the final bill.

How to estimate your monthly SMS budget

Start with the number of recipients, the number of campaigns you plan to send, and the average message length. For example, a business with 2,000 opted-in subscribers sending two campaigns per month would send 4,000 recipient messages if each campaign reaches the full list once.

Your estimate should account for:

The monthly subscription or minimum spend.
The cost of recipient messages at the applicable rate.
Extra message segments when texts exceed the standard length.
MMS charges if you send images or other media.
Carrier fees, number rental, registration, and required add-ons.

This is a budgeting example, not a quote from one vendor. Actual costs vary by platform and destination country.

Buyer tip: Ask each vendor to estimate your total monthly bill using your expected subscriber count, message frequency, recipient countries, and mix of SMS and MMS. Compare that estimate across vendors, not just the advertised entry price.

How to choose the right SMS marketing tool

1. Match the platform to your business model

Ecommerce: Compare Klaviyo, Postscript, and Omnisend for customer segmentation, purchase-related triggers, and coordinated email and SMS workflows.
Local businesses and organizations: Compare SimpleTexting, SlickText, and EZ Texting for campaign management, list growth, and credit allowances.
Variable message volume: Evaluate Textmagic’s usage-based approach and number costs.
Broader marketing: Consider Brevo if you want SMS alongside email and other marketing activities.
Larger brands: Evaluate Attentive if cross-channel campaigns, integrations, and dedicated support matter.

These are starting points for a shortlist, not proof that one product will suit every business in that category.

2. Check automation before buying

An SMS campaign is a one-time message sent to a selected audience. An automated SMS workflow sends messages when a defined event or condition occurs. Examples include a welcome message after signup, a cart reminder after a shopper leaves checkout, or a follow-up after a purchase.

If automation is a priority, check whether the platform supports your required triggers, audience rules, exclusions, delays, and reporting on the plan you intend to purchase. Some advanced features may be reserved for higher tiers.

3. Verify the integrations you need

An integration directory is useful, but the number of listed integrations does not tell you whether your workflow will work. Check whether the tool supports your ecommerce platform, CRM, website forms, analytics tools, or email service. Confirm which data flows in each direction and whether the connection requires an additional subscription or technical setup.

If you use a CRM, you can also compare options through our guide to CRM software.

4. Calculate total cost, not just the subscription

Before choosing a plan, calculate the likely cost at your current volume and at a larger volume. Ask each vendor:

How are SMS and MMS billed?
Do message credits expire or roll over?
Are carrier fees charged separately?
Does the plan include a sending number?
Are registration, setup, or onboarding fees required?
What happens when you exceed the included allowance?
Does the price change with destination country or message length?

These details can make a lower-priced subscription more expensive for your sending pattern.

5. Check consent, opt-outs, and regional requirements

Marketing texts should go to people who have agreed to receive them. Your platform should help you record consent, honor opt-out requests, and prevent unsubscribed contacts from receiving future campaigns.

The CTIA Messaging Principles and Best Practices recommend obtaining consumer consent before messaging and providing a clear way to opt out. These are industry best practices and do not replace applicable legal requirements. Rules vary by country and message type, so confirm the requirements for every market you serve.

If you send to US recipients, check sender registration and carrier requirements. For international messaging, confirm support for recipient countries, local sender rules, permitted sending hours, and applicable privacy and marketing laws.

6. Review reporting and support

Choose reporting that answers the questions your team needs to resolve. Depending on the campaign, that may include delivery, clicks, conversions, opt-outs, subscriber growth, and revenue attribution.

Also confirm what support is included. A small team running occasional campaigns may be comfortable with self-service documentation. A larger program with several integrations and complex workflows may need onboarding and a named support contact.

Which SMS marketing platform should you choose?

Choose Klaviyo if your ecommerce team wants customer segmentation and behavior-triggered SMS within a broader marketing workflow. Compare account-specific message rates before estimating costs.
Choose Postscript if you run a Shopify-focused SMS program and want ecommerce-specific acquisition tools, automation, and reporting.
Choose Omnisend if you want email and SMS campaigns in one ecommerce platform and can budget for the current Pro plan and separate SMS credits.
Compare SimpleTexting, SlickText, and EZ Texting if your priority is general business texting, promotions, event announcements, or reaching an opted-in contact list.
Consider Textmagic if your message volume varies and a usage-based model fits your needs.
Consider Brevo if you want SMS alongside broader marketing activities and prefer to buy credits as needed.
Evaluate Attentive if you operate a larger multi-channel messaging program and need integrations and tailored support.

Frequently asked questions

What is the best SMS marketing tool for small businesses?

SimpleTexting, SlickText, and EZ Texting are sensible starting points for small businesses that need general-purpose campaign texting. Compare included credits, sending-number options, carrier fees, and support. The best fit depends on how frequently you send messages and which countries you need to reach.

Which SMS marketing platform is best for ecommerce?

Klaviyo, Postscript, and Omnisend are strong candidates to evaluate. Klaviyo is worth considering for customer segmentation and automated marketing, Postscript for Shopify-focused SMS programs, and Omnisend for coordinating ecommerce email and SMS. Compare current plan requirements and total messaging costs against your store’s workflows.

Is there free SMS marketing software?

Some vendors advertise free plans or trials, but that does not necessarily mean you can run an ongoing SMS program at no cost. Postscript lists a $0 Starter subscription with a $49 monthly minimum spend, while other platforms may offer a trial or a free plan with different limitations. Review the current terms and message charges before signing up.

How much does SMS marketing software cost?

Costs range from usage-based message charges to monthly subscriptions and custom contracts. SlickText lists paid plans from $29 per month, SimpleTexting’s calculator displays a $39 monthly estimate for 500 credits and a local number, and EZ Texting lists its Launch plan from $25 per month. These examples use different billing models and are not directly comparable.

What features should an SMS marketing tool include?

At minimum, check campaign scheduling, audience segmentation, consent and opt-out management, delivery reporting, and clear pricing. If you need automated campaigns, verify the triggers, integrations, and workflow features available on your intended plan.

Do I need consent before sending marketing text messages?

You should obtain appropriate consent before sending marketing texts and provide a clear way for recipients to opt out. Legal obligations depend on where you and your recipients are located, the message type, and the sending method. Review applicable laws and carrier requirements for your target markets before launching a campaign. The CTIA guidelines also recommend honoring opt-out requests and maintaining appropriate consent records.

Can I use one SMS marketing platform for multiple countries?

Possibly, but international coverage and pricing vary by vendor. Check supported destinations, local sender requirements, message rates, permitted sending hours, and country-specific restrictions. Brevo documents country-specific pricing and sending rules, while SlickText says its SMS service currently supports the United States and Canada. See Brevo’s supported-country documentation.

Final recommendation

The best SMS marketing tool is the one that fits your campaign workflow and total budget, not necessarily the one with the lowest advertised starting price.

For ecommerce teams, begin by comparing Klaviyo, Postscript, and Omnisend. For straightforward business texting, compare SimpleTexting, SlickText, and EZ Texting. Consider Textmagic if usage-based pricing fits your message volume, Brevo if you want SMS alongside broader marketing, and Attentive if you need a larger multi-channel messaging program.

Before you subscribe, shortlist two or three tools and price the same realistic campaign with each vendor. Confirm the integrations, automation features, consent controls, and fees you will actually use. That comparison will give you a more useful answer than a feature checklist alone.
