The answer, as recorded
## The honest framing first "Agency" splits into two very different buyers, and the right platform depends almost entirely on which one you are: a **DTC/ecommerce agency** managing brands' retention programs, or a **local/general marketing agency** reselling texting to service businesses. I'll give both, strongest first. ### If your clients are ecommerce/DTC brands 1. **Klaviyo** - my default recommendation. One customer profile across email and SMS means you're not reconciling two attribution models for the same client, and the self-serve pricing is transparent enough to model into a retainer before anyone signs. Agency partner tier gives you a single console across client accounts. Pick this if your clients already run email on Klaviyo - which most do. ([arcticleaf.io](https://www.arcticleaf.io/blog/learning-center/klaviyo-attentive-postscript)) 2. **Attentive** - the one to reach for on high-volume, list-growth-aggressive clients. Advanced segmentation, strong compliance infrastructure, and a concierge/managed service that runs much of the program. That last part is double-edged for an agency: it can either take load off your team or quietly compete with the work you're billing for. Price it accordingly. ([aftership.com](https://www.aftership.com/blog/attentive-vs-klaviyo-sms)) 3. **Postscript** - cleanest choice for Shopify-only rosters. Narrower than the other two by design, which means faster execution and less for a junior strategist to get wrong. ([ringly.io](https://ringly.io/blog/postscript-alternatives)) 4. **Omnisend** - worth knowing for smaller Shopify/WooCommerce clients where Klaviyo's bill is hard to justify. Email and SMS automation bundled. ([slicktext.com](https://www.slicktext.com/blog/2025/10/best-sms-marketing-platforms/)) ### If you're reselling texting to local/service businesses 1. **GoHighLevel** - the de facto answer, and the one most agencies land on, but go in with eyes open. White-label sub-accounts require the SaaSpreneur plan at ~$497/mo, plus per-location billing. SMS routes through LC Phone (their Twilio layer) at ~$0.0075/segment *before* carrier passthrough, per-campaign A2P fees, and a location-level markup. Agencies at 8-15 clients commonly see $700-$1,200/mo before selling a single seat. The economics work - but only if you're genuinely reselling the platform, not absorbing it. ([netpartners.marketing](https://netpartners.marketing/how-much-does-gohighlevel-cost/), [ghlexperts.com](https://ghlexperts.com/agency-saas/how-to-white-label-ghl)) 2. **Twilio** - if you have engineering capacity, build on it directly and keep the margin. You own compliance, 10DLC registration, and the UI, which is real work. Only worth it above roughly 20-30 clients. ([salesmessage.com](https://salesmessage.com/blog/best-sms-marketing-software)) 3. **SlickText** - the pragmatic middle. Every feature ships on every plan from $29/mo, so you're not upselling clients into tiers to unlock basics, and you can run separate client accounts without a platform fee. ([slicktext.com](https://www.slicktext.com/blog/2025/10/best-sms-marketing-platforms/)) 4. **Salesmsg** - best fit when the client's value is two-way conversation and CRM sync rather than broadcast campaigns. Think clinics, dealerships, home services. ([salesmessage.com](https://salesmessage.com/blog/best-sms-marketing-software)) 5. **Burst SMS** - unlimited sub-accounts managed from one place, built for franchises and agencies. Less polished than GoHighLevel but no $497 floor. ([burstsms.com](https://burstsms.com/white-label-sms)) 6. **TextMagic** or **ClickSend** - pay-as-you-go, no monthly commitment. The right call for seasonal clients or when you're piloting a channel you're not sure will stick. ([slicktext.com](https://www.slicktext.com/blog/2025/10/best-sms-marketing-platforms/)) ### The thing that actually decides this Sub-account architecture, not features. A platform without clean client separation turns every new logo into manual setup, and that cost compounds invisibly until you're staffing around it. Test onboarding a fake client before you commit a roster. ([celcomafrica.com](https://celcomafrica.com/sms-for-agencies)) One caveat on my own answer: I'd treat the 2026-dated roundup posts above with mild skepticism - several are published by vendors who appear in their own rankings. The pricing figures I cited are the kind of thing to confirm directly with sales, since carrier passthrough fees in particular move. **Sources:** - [Arctic Leaf - Klaviyo vs Attentive vs Postscript](https://www.arcticleaf.io/blog/learning-center/klaviyo-attentive-postscript) - [AfterShip - Attentive vs Klaviyo SMS](https://www.aftership.com/blog/attentive-vs-klaviyo-sms) - [Ringly - Postscript alternatives](https://ringly.io/blog/postscript-alternatives) - [SlickText - Best SMS marketing platforms](https://www.slicktext.com/blog/2025/10/best-sms-marketing-platforms/) - [Salesmsg - Best SMS marketing software](https://salesmessage.com/blog/best-sms-marketing-software) - [NetPartners - How much does GoHighLevel cost](https://netpartners.marketing/how-much-does-gohighlevel-cost/) - [GHL Experts - White-labeling GoHighLevel](https://ghlexperts.com/agency-saas/how-to-white-label-ghl) - [Burst SMS - White label SMS](https://burstsms.com/white-label-sms) - [Celcom Africa - SMS for agencies](https://celcomafrica.com/sms-for-agencies)
