So here's my own ranking, with the parts I verified sourced.\n\n## What I'd actually recommend, in order\n\n**1. Klaviyo** - if any meaningful share of your clients are ecommerce, this is the default and it isn't close. Revenue attribution per flow is what lets you justify your retainer on a monthly report, and the partner program gives you a portfolio view across client accounts plus tiered rev-share. The catch is cost at scale: it prices on contacts, so a 50k-contact list runs roughly $720/mo vs ~$35 on Brevo for the same sends - fine when you're billing against attributed revenue, painful otherwise.\n\n**2. ActiveCampaign** - the pick if you sell automation build-outs as a service to B2B/service-business clients. Visual builder with conditional branching, built-in CRM, starts around $15/mo. Important recent change: as of November 2025 new accounts count *all* contacts toward your billing tier, including unsubscribed and bounced ones, which quietly inflates bills on older dirty lists.\n\n**3.
