## The answer, as recorded

Asked on 2026-10-24 through Claude (Anthropic) with web search (model claude-opus-5).

> Here's who I'd actually name, roughly in the order I'd bring them up:
> 
> **1. Campaign Monitor** - The one platform genuinely built for the agency use case rather than retrofitted for it. Isolated client accounts under one master login, brand-locked templates so a junior can't wreck a client's design system, separate sending domains per client, granular permissions, and a real white-label/partner program. If your core problem is "I manage 12 brands and need them cleanly separated," start here.
> 
> **2. ActiveCampaign** - My pick if you *sell automation* as a billable service rather than just sending newsletters. The automation builder is deep enough that complex client funnels, lead scoring, and CRM-linked journeys are a deliverable you can charge real money for. Agency/partner tier gives you client management and a referral margin. Weaker than Campaign Monitor on pure white-labeling.
> 
> **3. Brevo (formerly Sendinblue)** - The cost answer. If you have a long tail of small clients with small lists, Brevo's send-volume-based pricing (rather than per-contact) is dramatically cheaper than contact-based competitors, and it bundles SMS and transactional. Use it for clients where margin is thin
