The question asked, verbatim: best email marketing software for agencies
Brands named, in the order the engine gave
- ActiveCampaign mentioned
ActiveCampaign - My default pick for a general-purpose agency.
- Klaviyo mentioned
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.
- Shopify mentioned
Built around a customer data model rather than a list, deep native Shopify/WooCommerce/BigCommerce hooks, and per-subscriber predictive analytics.
- WooCommerce mentioned
Built around a customer data model rather than a list, deep native Shopify/WooCommerce/BigCommerce hooks, and per-subscriber predictive analytics.
- BigCommerce mentioned
Built around a customer data model rather than a list, deep native Shopify/WooCommerce/BigCommerce hooks, and per-subscriber predictive analytics.
- HighLevel mentioned
HighLevel (GoHighLevel) - The pick if you want to resell rather than just manage.
- GoHighLevel mentioned
HighLevel (GoHighLevel) - The pick if you want to resell rather than just manage.
- Campaign Monitor mentioned
Campaign Monitor - The most mature classic agency setup: one dashboard, client sub-accounts with granular permissions, white-label branding, and client-direct billing where you set your own markup.
- Brevo mentioned
Brevo - Best economics when you have many clients with small lists.
- Mailchimp mentioned
Mailchimp - I'd name it only for clients who insist on it or are very small.
- BigMailer mentioned
Worth knowing: BigMailer and Moosend are the budget plays if margin is the whole game - BigMailer is deeply white-labelable at roughly $6 per 5,000 contacts, Moosend starts ~$9/mo.

The answer, as recorded
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-label/SaaS mode means you put your own brand and your own pricing on it, plus it bundles CRM, pipelines, SMS, and funnels, so you're not stitching five vendors together. Best fit for local-business and lead-gen agencies. The tradeoff is that the email sending itself is merely fine - it's a business model, not a best-in-class ESP. **4. Campaign Monitor** - The most mature classic agency setup: one dashboard, client sub-accounts with granular permissions, white-label branding, and client-direct billing where you set your own markup. If your value-add is beautiful branded campaigns for several brand clients and you don't need heavy automation, this is the cleanest. From ~$12-13/mo. **5. Brevo** - Best economics when you have many clients with small lists. Pricing is send-volume-based rather than contact-based, so a client with 40K dormant contacts doesn't bankrupt you. Free tier plus paid from ~$9/mo, and transactional email/SMS included. **6. Mailchimp** - I'd name it only for clients who insist on it or are very small. Cheaper than Klaviyo at scale (~$350 vs ~$720 at 50K contacts on Standard) and everyone's bookkeeper already knows it, but the automation is weaker and agency tooling is thin. **Worth knowing:** **BigMailer** and **Moosend** are the budget plays if margin is the whole game - BigMailer is deeply white-labelable at roughly $6 per 5,000 contacts, Moosend starts ~$9/mo. Both are fine; neither will impress a sophisticated client. If you want one sentence: ecommerce clients → Klaviyo, everything else → ActiveCampaign, and HighLevel if your actual business model is reselling software under your own brand.
