Send promotional texts, alerts, and two-way SMS conversations to subscribers who have opted in.
SMS marketing tools are differentiated by how they collect consent, build segments, automate journeys, support two-way conversations, and connect text messages to email or ecommerce data. A retail brand running cart and post-purchase flows has different needs from a local business sending appointment reminders or a developer building a custom texting workflow. These five options represent those distinct approaches instead of a single ranking.

For combined email and SMS
#1 of 10 in SMS Marketing
Brevo (formerly Sendinblue) places SMS campaigns and automation next to email, CRM, and transactional messaging. The result is practical when the same marketing team wants to coordinate channels from shared customer data, not maintain a separate SMS-only system. Shared automation helps prevent email and SMS from operating as disconnected programs.
Custom SMS applications
#3 of 10 in SMS Marketing
Twilio provides programmable SMS and messaging APIs instead of a primarily campaign-led interface. Developers can build custom reminders, alerts, two-way messaging, verification, or marketing experiences and control how messages connect to the rest of the application. Developers can decide exactly when applications send, receive, and route text messages.
General business texting
#5 of 10 in SMS Marketing
SimpleTexting provides SMS campaigns, two-way texting, keywords, autoresponders, list management, and business messaging in a straightforward marketer-facing platform. It is worth a look if you need promotional texts, alerts, or customer conversations without adopting a full ecommerce retention suite; two-way replies can stay inside the same business texting environment.
For ecommerce retention SMS
#8 of 10 in SMS Marketing
Attentive covers consumer-brand SMS and email marketing, including subscriber acquisition, segmentation, automated journeys, personalization, and conversational messaging. It is suited to ecommerce teams that treat SMS as a major retention channel connected to shopper behavior; its workflows are built around recurring customer lifecycle communication instead of isolated blasts.
For Shopify-focused SMS
#10 of 10 in SMS Marketing
Postscript is centered on retention messaging for ecommerce, with SMS, conversational workflows, segmentation, and automation tied closely to store behavior. It is a good fit if you want text campaigns triggered by customer and order events, so messages do not go to a generic contact list.

An SMS keyword is a word customers text to a designated number to trigger an action, such as joining a list or requesting information. The response and consent language should clearly explain what messages the user is agreeing to receive.
They can share customer data and lifecycle logic, but the channels should not be treated identically. SMS is more interruptive and has stricter consent expectations, so frequency, timing, message length, and escalation should be designed specifically for text messaging.
Yes, Brevo (formerly Sendinblue), Klaviyo and Bird all offer a free plan. Free tiers usually come with usage limits, so check whether they cover your volume before relying on them long-term.
Among the tools listed here whose main product is in this category and whose pricing we've verified, Bird has the lowest listed starting price: $15/mo (varies by product). Starting price isn't the whole picture, so check what's included at that tier before deciding.
