## The answer, as recorded

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

> Here's what I'd actually recommend, roughly in the order I'd suggest evaluating them. The honest headline: there's no single winner - the right pick is mostly determined by what kind of clients are on your roster.
> 
> **1. Klaviyo** - If any meaningful share of your clients are e-commerce (Shopify, WooCommerce, BigCommerce), this is the default and it isn't close. Deep native store data means segmentation and flows you can't easily replicate elsewhere, and the revenue attribution reporting is what clients actually want to see. Their agency partner program gives you a unified portal across client accounts plus revenue share/referral commissions. Downside: pricing scales hard with list size, and it's overkill for a B2B services client.
> 
> **2. ActiveCampaign** - My pick for a mixed roster of B2B/service-business clients. The automation builder is still the most expressive at its price point, deliverability is consistently strong, and the CRM is good enough that smaller clients don't need a separate one. There's a real agency partner tier with client management and margin.
> 
> **3. Campaign Monitor** - The one built most explicitly for the agency operating model: true multi-account management

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.
