The answer, as recorded

Here's what I'd actually recommend, depending on what kind of agency you run: **1. ActiveCampaign** - My default pick for most agencies. The automation builder is deep enough that you can sell "we'll build your lifecycle program" as a real deliverable, and their agency partner program gives you a proper multi-client dashboard, free internal accounts, and revenue share/referral commissions. Starts around $15/mo per client account (annual). The catch: each client is a separate billed account, so costs scale linearly. **2. Klaviyo** - If any of your clients sell physical or digital products, this is the one. The Shopify/WooCommerce integration and revenue attribution reporting are best-in-class, and the agency partner program is genuinely lucrative (tiered commissions, directory listings that send you inbound leads). Clients pay directly, so you're not fronting costs. Weak choice for B2B/newsletter clients. **3. Campaign Monitor (Marigold)** - The one built specifically around the agency model: one login, client sub-accounts with granular permissions, white-label branding, and the ability to set your own markup and bill clients through the platform. From ~$12-13/mo for 500 contacts. The product itself is less sophisticated than ActiveCampaign, but if your value-add is design and management rather than complex automation, the admin layer saves you real hours. **4. Brevo** (formerly Sendinblue) - Best cost structure when you have a lot of small lists. Free tier, paid from ~$9/mo, and it bills on sends rather than contacts, which is a big deal for clients with big dormant lists. Also bundles SMS and transactional email. Good for boutique/lower-budget retainers. **5. MailerLite** - Where I'd send you if the clients are small businesses, creators, or nonprofits who will eventually take the account over themselves. Clean enough that a non-marketer can run it, and they have an explicit agency/partner setup with client account management. ~$10/mo. **6. HubSpot** - Only if you're doing full-funnel work and the email is attached to CRM, sales handoff, and attribution reporting. Overkill and expensive for email alone, but the Solutions Partner program is the most mature of any on this list if you want to build a retainer practice around one vendor. **7. BigMailer** - Niche but worth knowing: purpose-built for agencies with genuinely unlimited client brands under one account, white-labeled, with pooled credits. If you manage 10+ small clients and the per-account pricing on the others is killing your margin, this fixes exactly that problem. **What I'd skip:** Mailchimp. Its agency tooling has stagnated since the Intuit acquisition and the pricing got worse - you'll mostly encounter it as a platform you're migrating clients *off* of. One practical note: the real decision isn't features, it's billing architecture. Decide first whether you want clients paying the vendor directly (Klaviyo, HubSpot - cleaner, no cash-flow risk, less lock-in for you) or you reselling under your own brand (Campaign Monitor, BigMailer - better margin, stickier, but you're carrying the invoices). That narrows the list faster than any feature comparison.
