Looking into SMS marketing software. Tried any of these? Would love to hear how it went. Here are some I found:
Geared toward outreach automation. It looks like it’s built to scale outbound email and SMS campaigns in one place.
More of a full platform, but includes SMS features through integrations. It might be helpful for teams already using HubSpot for email and CRM.
Aimed at customer engagement across channels. Includes mobile marketing tools that look useful for personalized SMS outreach.
Longtime player in email, now also supports SMS. Appears to be a good option for teams running promotions or updates alongside newsletters.
It offers a mix of automation, email, and SMS. It could be a solid pick for teams looking to build sequences across multiple channels.
I'd appreciate your input on whether you’ve used or found something better.

Disclosure: I’m on the product marketing team at Insider One, but sharing this from what we consistently see across customer use cases. SMS tends to perform best when it’s treated as part of a broader customer experience rather than a one-off broadcast channel. Teams getting the most value from SMS usually focus on: • Behavior-based triggers instead of calendar-based blasts • Deep personalization using real-time customer data • Journey-level orchestration across channels (SMS working alongside email, app, web, etc.) • Built-in compliance and preference management as scale increases • Revenue and retention impact, not just delivery or CTR metrics What we have noticed, SMS is especially effective for use cases like lifecycle nudges, cart or browse reminders, replenishment alerts, and time-sensitive offers, where relevance and timing matter more than volume. For anyone evaluating tools, there are several established SMS vendors commonly considered in the market, depending on needs and team structure: 1. Attentive – Often chosen by e-commerce brands focused heavily on promotional SMS and subscriber growth. 2. SlickText – Known for simplicity and ease of use, particularly for small to mid-sized teams. 3. Twilio – A developer-first, API-driven option suited for highly customized messaging and infrastructure control. Ultimately, the “best” SMS marketing software depends less on rankings and more on how you plan to use SMS, whether that’s primarily promotional, lifecycle-driven, or as part of a broader, experience-led strategy. Happy to share learnings or examples if helpful. ##### Comment Metadata - Posted at: 6 months ago - Author title: Product Marketing Manager ### Comment 3 <p>SMS marketing software hasn't changed much yet in 2025.
