## The answer, as recorded

Asked on 2026-10-08 through Claude (Anthropic) with web search (model claude-opus-5).

> ## The honest framing first
> 
> "Agency" splits into two very different buyers, and the right platform depends almost entirely on which one you are: a **DTC/ecommerce agency** managing brands' retention programs, or a **local/general marketing agency** reselling texting to service businesses. I'll give both, strongest first.
> 
> ### If your clients are ecommerce/DTC brands
> 
> 1. **Klaviyo** - my default recommendation. One customer profile across email and SMS means you're not reconciling two attribution models for the same client, and the self-serve pricing is transparent enough to model into a retainer before anyone signs. Agency partner tier gives you a single console across client accounts. Pick this if your clients already run email on Klaviyo - which most do. ([arcticleaf.io](https://www.arcticleaf.io/blog/learning-center/klaviyo-attentive-postscript))
> 2. **Attentive** - the one to reach for on high-volume, list-growth-aggressive clients. Advanced segmentation, strong compliance infrastructure, and a concierge/managed service that runs much of the program. That last part is double-edged for an agency: it can either take load off your team or quietly compete with the work you're billi
