Klaviyo** - My default recommendation for most retention agencies. Email + SMS on one customer profile, the best segmentation and data model in the category, and a genuinely mature agency partner program with portfolio views across clients. If you want one platform you can standardize your whole book of business on, this is it. ([arcticleaf.io](https://www.arcticleaf.io/blog/learning-center/klaviyo-attentive-postscript))\n\n**2. Postscript** - Better than Klaviyo if your clients are Shopify-native and you want speed of execution over data depth. The partner program is the strongest of the three commercially: revenue share per referred client, an SMS certification course, and a dedicated partner manager. They launched an email product in September 2026 alongside SMS and RCS, so the \"SMS-only\" knock against them is going away. ([postscript.io/partners](https://postscript.io/partners/))\n\n**3. Attentive** - Where I'd go only for enterprise/high-volume DTC clients.
