## The answer, as recorded

Asked on 2026-10-10 through Claude (Anthropic) with web search (model claude-opus-5).

> The right pick depends more on *what kind* of agency you are than on feature checklists, so here's my ranked list with that split called out.
> 
> ## If you want to resell/white-label SMS as your own product
> 
> **1. GoHighLevel** - My default recommendation for agencies serving local businesses, home services, med spas, real estate, etc. It's the only one on this list built from the ground up as an agency operating system: unlimited client sub-accounts, true white-labeling (your domain, your branding, your pricing), plus CRM, funnels, booking, and two-way texting in one bill. SMS runs on Twilio under the hood, so you mark up message costs. Starts around $97/mo, $297/mo for the agency/unlimited tier. Downside: SMS is one module of a sprawling product, and support quality is a common complaint.
> 
> **2. SlickText** - Best "serious SMS tool with agency plumbing" if you don't need a whole CRM. Unlimited user seats with granular permissions, flexible billing (consolidate under your account or bill clients directly), and notably every feature is on every plan rather than gated into upsells. Strong list-growth tools. Good when GoHighLevel is too much platform.
> 
> **3. TextUs** - Worth a look specifi
