One caveat up front: most of the "best email marketing for agencies" listicles that come back are affiliate-driven and contradict each other (one crowns Campaign Monitor, the next crowns MailerLite, usually with the same boilerplate). So here's my actual ranking, which depends mostly on what kind of clients you serve. > > **First, the structural decision:** decide whether clients own their own account (you get invited as a user) or you resell under your agency's billing. Client-owned is the better default - you're not the billing intermediary, you're not holding their list, and churn doesn't hit your card. Only go white-label/reseller if marking up the software is a real revenue line for you. > > ### My picks, in order > > 1. **Klaviyo** - if any meaningful share of your clients is ecommerce/DTC, this is the default and it isn't close. Revenue-per-recipient attribution is what lets you show up to a retainer call with a number, segmentation depth is best in class, and the partner program is free with a portal for switching between client accounts. Each client keeps their own account and invites you in.

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.
