Here's the order I'd actually give:\n\n**1. Klaviyo - if any meaningful share of your clients are ecommerce.** It's the default for Shopify/WooCommerce work, and the agency partner program is the real draw: a partner portal with one-click access to all client accounts, revenue-attribution reporting that justifies your retainer at renewal time, and tiered partner status with referral commissions. The catch is cost at scale - ~$100/mo at 5,000 contacts vs ActiveCampaign's $49, and $400 vs $186 at 25,000 ([costbench](https://costbench.com/compare/klaviyo-vs-activecampaign/)). That's fine when it's billed to the client and attributed revenue covers it; it's painful if you're absorbing it.\n\n**2. ActiveCampaign - if you sell automation build-outs as a service.** Best-in-class visual automation builder, conditional logic, and CRM, which means the complex flows you build *are* the billable work.
