## The answer, as recorded

> **1. GoHighLevel** - The default answer for most marketing agencies. Full white-label (your logo, your domain), unlimited sub-accounts on the $297 Unlimited plan, and SMS is bundled into a broader CRM/funnel/automation stack so you're selling a platform, not just texts. Twilio runs underneath at roughly $0.0075/SMS US, rebillable to clients at your own markup - that resale margin is the real business case. Downside: it's a generalist tool, and deliverability tuning is on you.
> 
> **2. ProTexting / SmsTools / UltraSMSScript** - The narrower white-label SMS specialists. Client, credit, and keyword management in one admin panel, your branding, your pricing. Worth looking at if you want SMS as a standalone product line rather than a bolt-on to a CRM. UltraSMSScript in particular is self-hosted/licensed rather than per-seat SaaS, which changes the unit economics at volume.

> ## If your clients are ecommerce (Shopify DTC)
> 
> **3. Postscript** - The one I'd name first here. Shopify-native, transparent published pricing (
