## The answer, as recorded

Asked on 2026-09-26 through Claude (Anthropic) with web search (model claude-opus-5).

> Depends a lot on what your clients are, so here's how I'd actually rank them:
> 
> **1. Klaviyo - if your clients sell things online.** It's the default for ecommerce and it isn't close. Deep Shopify/WooCommerce data, revenue attribution per flow (which is what makes client reporting easy to defend at renewal), and a genuinely good partner program with free accounts for agencies plus referral commission. Downside: expensive at scale and overkill for a B2B services client.
> 
> **2. ActiveCampaign - the best all-rounder for mixed client rosters.** Strongest automation logic of the mainstream tools (conditional branching, split-testing whole automation paths, 1,000+ integrations), and it has a real agency/partner tier with client management and margin. This is my pick if your book of business is a mix of B2B, local services, and SaaS.
> 
> **3. Campaign Monitor - if white-labeling matters most.** It's the one built around the agency model: one dashboard, client sub-accounts, granular permissions, your branding on the login, and you set your own client pricing and bill through it. Less automation depth than ActiveCampaign, but the client-handoff ergonomics are the best here.
> 
> **4. Brevo - for cos
