Here's who I'd actually name:\n\n## If your clients are local/SMB service businesses\n**1. GoHighLevel** - This is the default for agencies in this space, and for good reason. It was built for the multi-client model: every client gets an isolated sub-account with its own data, branding, and workflows, and on the Unlimited plan there's no cap on sub-account count, so your software cost stays flat at 5 clients or 50. It's white-label, so you resell it as your own product. Downside: SMS is one feature in a sprawling all-in-one CRM, so the messaging depth is shallower than a dedicated tool. ([Anything GHL](https://anythingghl.com/klaviyo-vs-gohighlevel/), [TNW](https://thenextweb.com/news/gohighlevel-agency-software-platform))\n\n**2. Salesmsg** - Better pick if your clients already live in HubSpot or a real CRM and you want conversational two-way SMS rather than blast campaigns. Commonly recommended for mid-market accounts in the 1K-50K contact range alongside SlickText and Heymarket.
