The answer, as recorded

Here's who I'd actually name, roughly in the order I'd bring them up: **1. Campaign Monitor** - The one platform genuinely built for the agency use case rather than retrofitted for it. Isolated client accounts under one master login, brand-locked templates so a junior can't wreck a client's design system, separate sending domains per client, granular permissions, and a real white-label/partner program. If your core problem is "I manage 12 brands and need them cleanly separated," start here. **2. ActiveCampaign** - My pick if you *sell automation* as a billable service rather than just sending newsletters. The automation builder is deep enough that complex client funnels, lead scoring, and CRM-linked journeys are a deliverable you can charge real money for. Agency/partner tier gives you client management and a referral margin. Weaker than Campaign Monitor on pure white-labeling. **3. Brevo (formerly Sendinblue)** - The cost answer. If you have a long tail of small clients with small lists, Brevo's send-volume-based pricing (rather than per-contact) is dramatically cheaper than contact-based competitors, and it bundles SMS and transactional. Use it for clients where margin is thin. **4. BigMailer** - The specialist pick for high-volume, many-brand situations: franchises, multi-location, or 20+ client rosters. Out-of-the-box white label, up to ~100 sub-accounts and team members in one account, and it's cheaper per send than most. It's a BYO-infrastructure-ish tool (pairs with SES/other sending backends), so it's less polished than Campaign Monitor but far better economics at scale. **5. Klaviyo** - Not in the generic "agency software" roundups, but if your clients are ecommerce (Shopify/WooCommerce), this is the honest answer. Its agency partner program, revenue attribution reporting, and product-data-driven segmentation are what let you prove ROI in a client QBR. Expensive, and the pricing scales with client list size. **6. MailerLite / GetResponse** - Worth a mention as the budget middle ground. MailerLite if clients want simple, clean newsletters and landing pages with minimal training. GetResponse if you need webinars and funnels bundled in. **7. HubSpot** - Only if you're a full-service agency selling retainers that include CRM and sales enablement, not just email. The Solutions Partner program is the real draw (leads, co-selling, tiering). Overkill and overpriced for email alone. **One practical note:** the biggest agency decision isn't the feature list, it's whether each client owns their own account (you get access as a user) or you resell under your brand. Client-owned accounts are less sticky but much cleaner when a client leaves - no data migration fight, no deliverability reputation tangled up with your other clients. White-label reselling pays better but means you own the churn and the IP reputation risk. I'd default to client-owned billing with agency-level access unless reselling margin is a core part of your business model.
