## The answer, as recorded

Asked on 2026-10-04 through Claude (Anthropic) with web search (model claude-opus-5).

> The honest answer is that "best for agencies" splits by what your clients are, because the agency-specific features (sub-accounts, markup billing, white label) and the features your clients actually need rarely live in the same tool. Here's the order I'd actually give:
> 
> **1. ActiveCampaign** - My default recommendation for a general-purpose agency. Deep automation plus a built-in CRM means you can serve B2B, services, and local clients from one platform instead of learning three. Critically, it has a real reseller program with a reported 25-55% discount, which is the only agency-pricing model that reliably makes money (markup on a discount beats a referral commission). Also cheaper than Klaviyo at most contact tiers.
> 
> **2. Campaign Monitor (Marigold)** - The most purpose-built agency architecture on the list: one dashboard with client sub-accounts, granular per-client permissions, per-client branding, and - the useful part - you can either charge their base rates or mark them up, and they'll invoice your clients directly on your behalf. If your main pain is admin overhead across 15 clients rather than automation depth, start here. Its templates/design tooling are also the strongest
