The answer, as recorded

Searched; here's what I'd actually recommend. The split that matters: are you **reselling** texting under your own brand, or **operating inside clients' own accounts**? That determines the answer more than feature lists do. ## If you're reselling / white-labeling **1. GoHighLevel** - the default for general marketing agencies. Unlimited sub-accounts, white-label portal, snapshot cloning of campaigns across clients, and "SaaS mode" lets you rebill clients at your own markup. It's a CRM-plus-everything (pipelines, funnels, calls, two-way SMS) rather than a best-in-class SMS tool, which is exactly the tradeoff most agencies want. ([consultevo.com](https://consultevo.com/gohighlevel-vs-klaviyo-2026-comparison/), [nudgify.com](https://www.nudgify.com/gohighlevel-vs-klaviyo/)) **2. Twilio** - when you want to *be* the platform. Full control over routing, numbers, and 10DLC brand registration per client, cheapest per-message economics at volume. Cost is real engineering work; only worth it if messaging is core to your product, not a side service. ([slicktext.com](https://www.slicktext.com/blog/2025/10/best-sms-marketing-platforms/)) **3. Burst SMS** - a genuine middle ground: manage unlimited client accounts from one place with per-account permissions and white-label branding, without building on raw APIs. ([burstsms.com](https://burstsms.com/white-label-sms)) ## If you're running clients' own accounts **4. Klaviyo** - my first pick for ecommerce rosters. Email and SMS in one profile/segment model means you're not stitching attribution together, and the agency partner program gives you a single login surface across clients. Weaker than the SMS specialists on pure messaging depth. ([aftership.com](https://www.aftership.com/blog/attentive-vs-klaviyo-sms)) **5. Attentive** - for enterprise and high-volume clients. Strongest list-growth and compliance infrastructure, plus managed-service strategists on top packages. Quote-based pricing roughly $500-$5,000/mo with minimum commitments, so it's wrong for small accounts. ([costbench.com](https://costbench.com/compare/attentive-vs-postscript/), [arcticleaf.io](https://www.arcticleaf.io/blog/learning-center/klaviyo-attentive-postscript)) **6. Postscript** - the Shopify-only counterpart to Attentive, and the easier sell to smaller clients: public self-serve pricing from $0/mo with a $49 minimum, ~$0.015/SMS. No email, so it assumes Klaviyo lives alongside it. ([resources.rework.com](https://resources.rework.com/tools/messaging-sms/attentive-vs-postscript), [sequenzy.com](https://www.sequenzy.com/versus/postscript-vs-attentive)) **7. SimpleTexting / SlickText / EZ Texting** - the SMB-local tier (restaurants, gyms, clinics, dealerships). SlickText starts around $29/mo. Fast to stand up, clean pricing, no ecommerce assumptions. ([slicktext.com](https://www.slicktext.com/blog/2025/10/best-sms-marketing-platforms/), [eztexting.com](https://www.eztexting.com/resources/best-sms-marketing-platform)) **8. Salesmsg** - if clients' SMS is conversational rather than broadcast. Sits on HubSpot/other CRMs so reps text from where they already work. ([salesmessage.com](https://salesmessage.com/blog/best-sms-marketing-software)) **9. TextMagic or ClickSend** - pay-as-you-go for seasonal or one-off client campaigns where a monthly platform fee makes no sense. ([ddiy.co](https://ddiy.co/sms-marketing-software/)) ## The thing that will actually bite you Per-client **10DLC brand and campaign registration** in the US. Vetting delays, throughput tiers, and carrier passthrough fees (~$0.004/SMS on top of platform rates) hit agencies hardest because you're onboarding many brands, not one. Ask any vendor specifically how registration is handled per sub-account and who owns the brand record if a client leaves - that answer separates agency-ready platforms from ones that merely have sub-accounts. ([ustechautomations.com](https://ustechautomations.com/resources/blog/automate-best-sms-marketing-software-for-agencies-2026)) One caveat on sourcing: a lot of the "best of 2026" pages above are vendor-owned or affiliate content, so I'd treat the rankings in them as marketing and the pricing/feature specifics as the useful part. Pricing on the quote-based vendors especially is worth confirming directly.
