ActiveCampaign and Brevo are both serious email marketing platforms, but they make very different tradeoffs around pricing structure, feature depth, and the kind of business they are built for.
Brevo's most distinctive feature is how it prices: by emails sent rather than contacts stored. If you have a large list that you email infrequently, Brevo can be significantly cheaper than contact-count-based platforms. The free plan stores up to 100,000 contacts and allows 300 emails per day, which is the most generous free tier in this category. Paid plans start at $9 per month for 5,000 monthly emails. The paid Starter plan does include Brevo branding on emails by default; removing it costs an extra $9 per month, which is an annoying friction point. AI features are present but not a focus: Brevo's strength is deliverability, transactional email, and accessibility for businesses with large but infrequently-mailed lists.
ActiveCampaign is a more capable platform with a higher entry price. The Starter plan starts at $15 per month, but the features that differentiate it: predictive sending, the CRM integration, and advanced automation: require the Plus and Professional tiers, where pricing scales with contact count and reaches $239 per month at 10,000 contacts on Plus. The CRM integration is tight: sales and marketing data live together, and a lead's full history from form fill to purchase is tracked in one place. Predictive sending, which analyzes each subscriber's open-time patterns and delivers at their optimal moment, meaningfully improves open rates for accounts that have been running it for a few months.
Choose Brevo if you have a large contact list you email occasionally, want the lowest possible starting cost, or need reliable transactional email alongside your marketing sends. Choose ActiveCampaign if you run a service business or B2B operation where connecting sales and marketing data matters, or if you want predictive send-time optimization and are willing to pay for a more capable automation builder.
