## The answer, as recorded

Asked on 2026-10-03 through Claude (Anthropic) with web search (model claude-opus-5).

> The right answer depends on what kind of agency you are, so here's my ranked list with that split called out.
> 
> ## If you serve ecommerce/Shopify brands
> 
> **1. Klaviyo** - My default first recommendation for most agencies. Email + SMS in one data model means you build segments once and use them across channels, and the agency partner program is mature with client account switching. SMS is technically an add-on to the email platform, but the unified lifecycle control is worth more to an agency than a best-in-class standalone SMS tool. Roughly $3K-$7K/mo at 100K subscribers.
> 
> **2. Postscript** - Best pick when the client is Shopify-native and SMS is the primary revenue channel, not a supporting one. Every workflow assumes Shopify, so the integration depth beats generalist platforms, and its conversational/AI selling features are genuinely strong. Sweet spot is $1M-$50M Shopify brands, ~$5K-$10K/mo at 100K subs. Weak email, so expect to pair it.
> 
> **3. Attentive** - Only for enterprise clients. Advanced AI, cross-channel orchestration, enterprise compliance and a dedicated CSM - but $8K-$15K/mo at 100K subs, so it's hard to justify below roughly $50K/yr in SMS spend. Enterprise discounts
