The answer, as recorded
The "best" here depends on which kind of agency you are, so I'll split it that way - the thing that separates an agency platform from a normal one is sub-accounts, white-labeling, and who gets billed. **If you want one platform to run all clients under your own brand** 1. **GoHighLevel** - the default answer for most marketing agencies. It's built around sub-accounts ("locations"), full white-label (your domain, your logo, your app), and SaaS Mode so you can resell it at your own price and bill clients directly. SMS is Twilio under the hood, so you get wholesale-ish rates plus your markup. Downside: it's a whole CRM you have to learn and support, and deliverability/compliance is your problem, not theirs. 2. **Brevo** - email + SMS + WhatsApp in one, with an agency partner program and sub-account management. Best pick if your clients want SMS as one channel inside a broader lifecycle program rather than SMS as the product. 3. **SimpleTexting** - has a proper white-label reseller program on your own domain, and it's genuinely pleasant to use. Good middle ground when GoHighLevel is more machinery than you need. 4. **SmsTools** or **ProTexting** - reseller-first platforms where you create client sub-accounts, set your own per-SMS rate, and clients pay you. Thinner products, but the economics are the cleanest if reselling messaging *is* the business. **If you're managing clients on their own accounts (agency seat model)** 5. **Klaviyo** - if any meaningful share of your clients are Shopify/e-commerce, this is where the money is. The agency partner program gives you a partner portal, client account access, revenue share, and tiering. SMS shares the same profiles and segments as email, which is the real reason to use it. 6. **Attentive** - enterprise/DTC retail clients with big lists. Strongest list-growth and compliance operation in the category, expensive, and not resellable - you manage it on the client's account. 7. **Salesmsg** - best when the use case is conversational: sales and support teams texting two-way, tight HubSpot/ActiveCampaign integration, and a multi-org setup for handling several clients. 8. **EZ Texting** or **SlickText** - reliable, cheap, easy to hand off to a non-technical client. Fine for local/SMB books of business where you need broadcasts and keywords, not architecture. **If you're technical and want margin** 9. **Twilio** (or **Telnyx** / **Sinch**) - raw API, sub-accounts per client, and you build the UI. Only worth it if you already have engineering and volume; otherwise you're rebuilding GoHighLevel badly. Two practical notes that matter more than platform choice in the US: 10DLC brand/campaign registration is per-client, not per-agency, so budget time for the vetting queue on every onboarding; and make sure whoever you pick gives you per-client opt-in records and audit trails, because TCPA exposure lands on you as the sender.
