## The answer, as recorded

Asked on 2026-10-01 through Claude (Anthropic) with web search (model claude-opus-5).

> Agencies really split into two camps here - you either manage campaigns inside client-owned accounts, or you resell messaging under your own brand. The answer differs a lot by which one you are, so here's my ranked list with that flagged.
> 
> ## If you run campaigns in client accounts (most agencies)
> 
> 1. **Klaviyo** - My default recommendation if any meaningful share of your clients are Shopify/e-commerce. Email + SMS in one profile, the agency partner program is genuinely good (free dev/sandbox accounts, a client-account switcher, revenue attribution you can put in a report), and clients already know the name so you're not selling them on the tool. Downside: priced on contacts + sends, so it gets expensive on big low-value lists.
> 
> 2. **Attentive** - Where to go for enterprise retail/DTC clients doing real volume. Best-in-class list growth (two-tap signup units, identity resolution) and deliverability/carrier relationships. It's a managed, contracted product with a strategist attached, not something you self-serve, so it's overkill for SMB clients.
> 
> 3. **SimpleTexting** or **SlickText** - The practical picks for non-ecommerce SMB clients: local services, gyms, clinics, restaurants. Bo
