## The answer, as recorded

Asked on 2026-09-13 through Claude (Anthropic) with web search (model claude-opus-5).

> ## Short answer
> 
> There's no single winner - the right pick depends mostly on whether your clients are ecommerce or B2B/service, and whether you need to resell under your own brand. Here's how I'd rank them.
> 
> **1. Klaviyo - default for ecommerce clients.** Deepest Shopify/WooCommerce integration, behavior-based segmentation, and revenue-attribution reporting you can hand to a client without rebuilding it. Its agency partner program gives you a client dashboard and referral revenue, but note it's *not* white-label - Klaviyo branding stays visible, and per-contact pricing compresses your margin as client lists grow.

> 
> **2. ActiveCampaign - default for B2B, SaaS, and service clients.** The best automation logic of the mainstream tools, plus a usable built-in CRM, so it covers lead nurture as well as broadcast. The catch is agency economics: you pay per client account (Plus tier ~$49/mo each, so ~$490+/mo across ten clients) with no white-labeling.
