## The answer, as recorded

Asked on 2026-09-23 through Claude (Anthropic) with web search (model claude-opus-5).

> Agencies actually fall into two buckets here, and the right answer differs sharply depending on which you're in - so I'll name the picks in order, flagging the fit.
> 
> ## If you're running clients' programs under your own brand (local/service businesses)
> 
> **1. GoHighLevel** - The default for agencies, and it's not close in market share. You get white-label branding, client sub-accounts, rebilling, and "SaaS Mode" so you resell at your own margin. $97/$297/$497 per month at the agency level with unlimited users and contacts; what scales is sub-accounts and rebilling. Messaging is metered on top - roughly $0.0075/segment plus carrier fees plus a 5% markup, so budget ~$11.47 per 1,000 segments, not $7.47. The real operational tax: A2P 10DLC registration happens per sub-account, not agency-wide (~$24.50 one-time, $2-10/campaign/month), so onboarding each client has friction. Pick it if SMS is one piece of a CRM/funnel/booking stack you're selling.
> 
> **2. Salesmsg** - The best pick when you don't want a whole CRM. It has a genuine multi-organization environment for switching between client workspaces, and it's the strongest of the group at two-way conversational texting tied to HubSpot/Act
