How We Rank Email Marketing Software
100-point rubric · 6 weighted criteria
Gold — Best in Category
90+ points. Excellent across every criterion.
HubSpot
The all-in-one CRM platform for growing businesses
HubSpot is the dominant all-in-one CRM platform for B2B businesses and one of the best free tools in any software category. It earned a Gold tier rating because its free CRM is genuinely functional (not feature-crippled), its integrated marketing, sales, and service hubs eliminate data silos, and its ecosystem of 500+ integrations makes it the safe default for growing businesses. The steep jump to Professional pricing ($890/month) is the main caveat.

ActiveCampaign
Email marketing, automation, and CRM in one platform
ActiveCampaign is the gold standard for email marketing automation, combining a visual automation builder, built-in CRM, and industry-leading deliverability (98%+) at a price point that undercuts enterprise alternatives. It earned a Gold tier rating because no other platform in this price range matches its automation depth, segmentation power, and CRM integration. If you're a B2B business, SaaS company, or agency that relies on automated lead nurture, ActiveCampaign is the clear recommendation.

Klaviyo
The e-commerce email platform built for revenue
Klaviyo is the best email and SMS marketing platform available for e-commerce brands, period. It earned a Gold tier rating because no other platform matches its native Shopify integration, revenue attribution accuracy, or e-commerce-specific automation flows like abandoned cart, browse abandonment, and winback sequences. If you sell physical or digital products online and want to know exactly how much revenue every email generates, Klaviyo is the answer.
