## The answer, as recorded

Asked on 2026-10-09 through Claude (Anthropic) with web search (model claude-opus-5).

> Short answer: it depends less on "which tool sends the best email" and more on what your clients are. Here's how I'd rank them:
> 
> **1. ActiveCampaign** - My default pick for a general-purpose agency. Its automation builder is still the best in the category for the price, the Agency Partner program gives you a free internal account, client sub-accounts, and revenue share, and it handles B2B/service/SaaS clients that Klaviyo would be wrong for. Starts around $15/mo per client account. This is what I'd pick if I had to standardize one platform across a mixed book of business.
> 
> **2. Klaviyo** - Non-negotiable if your clients are ecommerce. Built around a customer data model rather than a list, deep native Shopify/WooCommerce/BigCommerce hooks, and per-subscriber predictive analytics. The agency partner program is genuinely good (free dev accounts, lead referrals, certifications your team can put on the site). Expensive at scale - roughly $100/mo at 5K contacts and $720/mo at 50K - but for a store doing real volume, the revenue attribution reporting is how you justify your retainer.
> 
> **3. HighLevel (GoHighLevel)** - The pick if you want to *resell* rather than just manage. True white-lab
