## The answer, as recorded

Asked on 2026-09-07 through Claude (Anthropic) with web search (model claude-opus-5).

> For agencies the deciding factors are different from what a single brand cares about: client sub-accounts with isolated lists and sending reputation, granular team permissions, white-label/branded logins, reporting you can hand a client without rebuilding it, and reseller/markup billing. Ranked by what I'd actually recommend:
> 
> **1. Klaviyo** - the default if your clients are ecommerce (Shopify/WooCommerce/BigCommerce). Deepest behavioral segmentation and revenue attribution in the category, and its partner program is built around agencies managing multiple stores. Downside: it's the most expensive per contact, and pricing is contact-based with SMS billed separately.
> 
> **2. ActiveCampaign** - the best generalist pick for a mixed client roster (B2B, services, ecommerce). Strongest automation-builder-plus-CRM in one tool, so you're not stitching together an ESP and a pipeline tool. Agency sub-accounts live in the Enterprise tier via their Reseller/Agency program - custom-quoted, not public. Notably cheaper than Klaviyo at equivalent contact tiers (~$140/mo less at 50k contacts).
> 
> **3. Campaign Monitor** - the most explicitly agency-shaped product on this list. Purpose-built agency dash

Answer Watch records what one AI answer engine said on one date, nothing more. Each page names the engine and the model, carries the date the question was asked, and lists the brands that appeared in the answer in the order the engine gave them, with the sources it cited. It is a measurement, not a ranking, not a recommendation and not a claim about the world. Brands that did not appear in an answer are not named on any public page.
