These two get compared because both sit one step above the starter email tools and both cost less than Klaviyo or HubSpot. They charge for different things. ActiveCampaign bills by contacts and sells automation depth. Brevo bills by emails sent and sells reach: unlimited contacts, transactional email, SMS and WhatsApp under one roof. Decide which of those two things your business is short of, and the choice mostly makes itself.
Pricing at realistic list sizes
At the time of verification (2026-09-09), ActiveCampaign shows only annual-billed rates: Starter is $15 a month at 1,000 contacts, Plus $49, Pro $79 and Enterprise $145, all at 1,000 contacts and all with the price rising as the list grows. There is no free plan, only a 14-day trial, and monthly-billing prices are not displayed on the pricing page. Brevo's free plan has no contact limit and allows 300 emails a day with Brevo branding. Starter is $9 a month ($8.08 annual) for 5,000 emails, Standard is $18 ($16.17 annual) for the same volume with automation, and Professional jumps to $499 at 150,000 emails a month.
At 1,000 contacts the two are close on paper and far apart in what you get. ActiveCampaign Starter at $15 buys one user, limited segmentation and automations capped at 5 actions each; the tier an automation buyer actually needs is Plus at $49. Brevo Standard at $18 includes marketing automation, A/B testing and send-time optimisation for any number of contacts, as long as you stay inside 5,000 emails a month, which at 1,000 contacts is five sends per contact.
At 10,000 contacts the gap opens. ActiveCampaign's contact-based price climbs with the list regardless of how often you send. Brevo's price does not move with contacts at all; a 10,000-contact list mailed twice a month needs roughly 20,000 emails, which is a Standard plan at a higher email tier, still a fraction of ActiveCampaign Plus at the same list size. If the list is large and the sending is light, Brevo is the cheaper tool by a wide margin.
The add-ons matter on both. ActiveCampaign sells the CRM pipeline, sales engagement, SMS, WhatsApp and reporting as extras on top of the marketing plan. Brevo keeps SMS and WhatsApp inside the platform but bills them per message, sells logo removal on Starter for $10.80 a month, and puts the sales CRM in a separate product. Neither headline price is the number on the invoice; write down the add-ons you know you need before comparing tiers.
Automation and feature depth
ActiveCampaign's automation builder is the reason to buy it. Multi-branch workflows trigger on email engagement, site visits, form submissions, deal stages and custom events; Pro adds predictive sending, conditional content and attribution, and there are more than 950 pre-built recipes to start from. Segmentation is tiered, from limited on Starter to advanced on Pro, and lead scoring is built into the model. If you can draw your customer journey as a flowchart with more than three branches, ActiveCampaign is the tool that will run it.
Brevo's automation is real but flatter. Standard includes a visual workflow builder with the usual triggers (signup, click, page visit, purchase event) and the sequences most small businesses actually run: welcome, abandoned cart, re-engagement, birthday. Where Brevo is stronger is breadth: transactional email through the same account and API, SMS and WhatsApp campaigns, push notifications on Professional, and a shared inbox. A business that needs order confirmations and a monthly newsletter from one vendor gets that from Brevo and not from ActiveCampaign.
Ease of use
Brevo is the easier tool. Campaign creation is quick, the free plan onboarding is short, and the plan limits are stated in emails, which anyone can count. The friction is sending approval on a new account and the add-on structure. ActiveCampaign's builder is powerful and takes real time to learn, and its modular plans make it hard to know which tier you need before you have used it; most people pick Starter, hit the 5-action cap, and upgrade inside the first month.
Exit cost
Higher on ActiveCampaign. Months of automation logic, lead scores and a CRM if you added it do not export; contacts do. Leaving means rebuilding the workflows elsewhere. Brevo's exit is lighter because the automations are simpler and the transactional email is an API integration you can point at another provider. If you are not sure the tool is right, Brevo is the cheaper mistake.
Scenario by scenario
A consultancy nurturing leads from a webinar into sales calls: ActiveCampaign Plus, with the CRM add-on if the pipeline is not already elsewhere. The branching sequence is the product.
A local retailer with 8,000 customers on a list mailed twice a month: Brevo Standard. Contact-based pricing would make this list expensive for what it does.
A SaaS or online store that needs receipts and password resets plus a newsletter: Brevo, because transactional and marketing email live in one account and one API.
A course business running an evergreen launch with segments by interest and behaviour: ActiveCampaign Plus or Pro. Brevo can run the welcome and the cart flow; it cannot run the branching launch.
A business that texts customers appointment reminders and promotions: Brevo, for SMS and WhatsApp campaigns in the same tool, priced per message. ActiveCampaign sells SMS as an add-on.
A list under 500 contacts with one welcome sequence: neither yet. MailerLite does that free, and the email list from zero guide covers the setup.
What neither does well
Neither is a newsletter tool for a writer; Kit is built for that. Neither is a store-first email platform; if the trigger for everything is a cart event on Shopify, the Klaviyo vs ActiveCampaign comparison covers that line. And neither is transparent at checkout: ActiveCampaign hides monthly pricing and stacks add-ons, Brevo charges to remove its logo and bills SMS separately. The tool you sign up for at $15 or $9 is not the tool you will pay for three months later; price the tier you will actually use.
