The answer, as recorded

Depends on one fork in the road: are you managing accounts the *client* owns (you're agency-of-record on their seat), or reselling messaging under your own brand? Different lists. Here's who I'd actually name. ## If clients own the account and you manage it **1. Klaviyo** - My default for ecommerce agencies. SMS and email run off the same profiles, segments, and flows, so you're not rebuilding audience logic twice or reconciling two attribution reports. Partner tiers give you a managed-accounts dashboard and rev-share. The pitch that holds up: one tool, one set of automations, [per Arctic Leaf's comparison](https://www.arcticleaf.io/blog/learning-center/klaviyo-attentive-postscript). **2. Attentive** - Where I'd go for larger retail clients. Best-in-class deliverability, dedicated short codes, serious list-growth tooling. The catch is contract shape: platform fee starts around $300/mo but quarterly minimums of $2,000-3,000 are typical and mid-market brands land at $1,500-5,000/mo - so it only makes sense for clients with real volume, not your $3k/mo retainer accounts. **3. Postscript** - Shopify-only, SMS-only, and that focus is the point: fastest to launch, deepest Shopify-native features. Their [partner program](https://postscript.io/partner-resources) is the most agency-friendly of the three - dedicated partner support, an SMS certification course, direct product-team access. If your book is Shopify DTC, start here before Attentive. **4. SimpleTexting or SlickText** - For non-ecommerce clients: local services, clinics, gyms, nonprofits, events. Keyword campaigns, two-way inbox, clean UI you can hand to a client without training. SlickText is the highest-rated in the category on G2 at 4.8/5 ([their own roundup](https://www.slicktext.com/blog/2025/10/best-sms-marketing-platforms/), so grade accordingly). SimpleTexting also has a reseller tier if you want to rebrand the interface. ## If you want to resell under your own brand **5. GoHighLevel (Agency Pro / SaaS Mode, $497/mo)** - The honest answer for local-services and white-label agencies, even though it's a full CRM rather than an SMS tool. SaaS Mode lets you rebrand it, set your own tiers, and rebill Twilio usage with a markup multiplier. [Reported tiers](https://ghlexperts.com/gohighlevel-plans-pricing) are $97 / $297 / $497, with rebilling only on the top plan. Margin math works out around the third rebilled client. **6. Twilio** - Not a marketing platform; it's the pipes. Worth naming only if you're building your own client-facing product or need fully custom logic. You inherit the whole compliance and UI burden, which is exactly what the platforms above are charging you to avoid. **7. Textmagic or Text Marketer** - Straight commission-style reseller models if you'd rather refer than operate. Text Marketer does sub-accounts with credit transfer and ~10% lifetime commission (£50/mo minimum); TextAnywhere pays up to 20% and handles billing and support for your referred clients. ## One thing that'll bite you 10DLC brand and campaign registration is per-brand, and carriers care whose EIN is on it. Register under the *client's* entity, not your agency's - otherwise you're the brand of record for messages you don't control, their throughput is pooled with everyone else's, and you can't cleanly hand the number over when they churn. The single exception is genuine white-label resale, where you're the brand on purpose. My pick if you forced one: **Klaviyo** for ecommerce books, **GoHighLevel** for local-services books. Caveat on the numbers: pricing above comes from vendor and affiliate-leaning blogs, not vendor price sheets - treat the dollar figures as ballpark and confirm on a sales call, especially Attentive's minimums.
