How We Compared ActiveCampaign vs Brevo
8-criteria methodology · Real testing · No pay-for-rank
We created real accounts on both ActiveCampaign and Brevo, ran real workflows, and verified pricing from each vendor's website in 2026. We consulted domain experts in email marketing before publishing. No vendor saw this review before it went live. No one paid for placement. Full methodology →
1. ActiveCampaign: Best Automation and CRM Platform (Our Top Pick)
ActiveCampaign's workflow builder is why you pay the premium. 40+ triggers, 50+ actions, and a visual builder that actually shows you what your automation does before you turn it on. Someone visits your pricing page twice without signing up? Trigger a 'still interested?' email, tag them as warm, and create a CRM deal. All automatically, no Zapier, no engineering help.
The built-in CRM is the part nobody talks about but everyone ends up using. Lead scores update based on email engagement. Deals auto-create when behavior patterns match your best customers. For B2B teams running multi-touch nurture sequences that hand warm leads to sales, having email and CRM in one place eliminates the 'did marketing send them the case study or do I need to?' confusion. It is not the prettiest tool, but it's the one that does the most actual work.
ActiveCampaign: Who Should Choose It
2. Brevo: Best Value Email and SMS Platform
300 emails a day. Unlimited contacts. SMS credits included. Chat widget. Transactional emails. All free. Not a trial, not 'first 90 days,' free. Brevo's free tier makes every other platform's look stingy. For a business with 10,000 contacts sending daily, that's $0/month vs $20-150 on Mailchimp or ActiveCampaign.
Brevo bundles channels that competitors sell as add-ons. Email and SMS and WhatsApp and chat and transactional emails in one platform at one price. The automation builder will not match ActiveCampaign's complexity, but it handles the 80% of workflows most businesses need. If you're running a business where every dollar counts, Brevo is hard to argue with.
Brevo: Who Should Choose It
3. HubSpot Marketing Hub: Best Full-Stack Marketing Suite (B2B)
HubSpot Marketing Hub is the most complete marketing platform on this list. Email marketing is just one component inside a full suite that includes CRM, automation, landing pages, SEO tools, social media management, ads, multi-touch attribution, and AI-powered content generation. For B2B teams wanting marketing and sales under one login, nothing else comes close.
The integration with HubSpot's free CRM is the differentiator. Every email open, every landing page visit, every ad click flows into one contact record that both marketing and sales can see. Lead scores update automatically based on engagement behavior. Deals auto-create when a contact crosses a threshold. This closed-loop marketing-to-sales handoff is what ActiveCampaign approximates but HubSpot perfected.
The catch is cost at the Pro tier. Starter at $20/month gives you email marketing, forms, and basic ads. But to unlock real automation, attribution, and SEO tools, you need Marketing Hub Professional at $890/month for 2,000 contacts. That's 40x Mailchimp and nearly 20x ActiveCampaign. For teams that will actually use the full suite, the ROI is there. For teams that just want to send newsletters, it's overkill.
HubSpot Marketing Hub: Who Should Choose It
4. Mailchimp: Most Recognized, Easiest to Start
Mailchimp is the brand your mom has heard of. The onboarding is the best of the five. Signup to first send in 15 minutes. Templates are genuinely beautiful (their Creative Assistant uses AI to generate branded designs from your website). 200+ integrations. The editor is so intuitive that non-technical team members can build and send campaigns without asking for help.
The catch is cost at scale. Mailchimp's free tier is solid at 500 contacts. But at 5,000 contacts on the Standard plan, you're paying $100/month. Brevo gives you unlimited contacts for $0-25. ActiveCampaign gives you a CRM for $49. Mailchimp charges a brand premium, and you feel it as your list grows. For small lists, it's wonderful. For growing lists, the math gets uncomfortable.
Mailchimp: Who Should Choose It
5. Klaviyo: Best for Ecommerce (Shopify-Native)
Klaviyo answers one question better than any other platform: how much revenue did this email generate? Not opens, not clicks. Actual dollars. Shopify integration is native and deep: abandoned cart flows trigger automatically, product recommendations generate from browsing history, and every email ties back to purchases. For an online store, this data is worth more than any template library or automation builder.
But that's also the box Klaviyo lives in. It is an ecommerce specialist. No CRM. Minimal non-product templates. The feature set assumes you're selling physical or digital products online. If you're a B2B company, a newsletter writer, or a service business, you're paying for ecommerce firepower you cannot aim at anything. Brilliant at what it does. Just make sure what it does is what you need.
Klaviyo: Who Should Choose It
Why Email Marketing Software Matters in 2026
Email marketing remains the highest-ROI channel at $36-42 for every $1 spent. But inbox providers have become significantly more sophisticated. Gmail's AI-powered spam filtering, Apple Mail Privacy Protection hiding open rates, and stricter authentication requirements mean the platform you choose directly impacts whether your emails land in the inbox or the spam folder.
The market has segmented clearly. Automation-first platforms like ActiveCampaign serve B2B teams needing complex sequences and CRM integration. Value-focused platforms like Brevo bundle email with SMS and chat at aggressive prices. Beginner-friendly tools like Mailchimp prioritize ease of use and templates. Full-suite B2B platforms like HubSpot Marketing Hub integrate CRM, ads, social, and SEO with email. Ecommerce specialists like Klaviyo track revenue per email and automate abandoned cart flows.
We evaluated all five platforms across deliverability, automation depth, template quality, pricing transparency, and multi-channel capabilities. Below is what matters for your subscriber count and use case.
What Changed in Email Marketing in 2026
Email marketing in 2026 is defined by AI. Subject line generators, send-time optimization, and AI-powered segmentation are now standard across every platform. Mailchimp's AI predicts the best send time per subscriber. ActiveCampaign's AI scores leads and triggers automations automatically. Brevo's AI generates entire email sequences from a prompt. What was premium in 2024 is table stakes now.
The second shift: SMS and multi-channel are bundled by default. Brevo includes SMS and chat in its free tier. Mailchimp added SMS credits. ActiveCampaign has site tracking and event-based triggers. Email-only platforms are losing to suites that handle the full customer journey.
Deliverability became a competitive moat. With Gmail and Yahoo sender requirements still tightening, platforms investing in authentication are winning. ActiveCampaign and Brevo lead on deliverability. Mailchimp has the most recognizable sending infrastructure.
Switching Email Platforms: Migration Checklist
Switching email platforms means migrating your list, automations, templates, and reporting. Here's what teams who did it successfully recommend.
How We Tested These Platforms
We built and sent 3 email campaigns (a 5-email welcome sequence, a promotional blast, and an abandoned-cart automation) across all 5 platforms to a test list of 1,000 subscribers. We measured deliverability rates, automation builder UX, and template design flexibility. ActiveCampaign had the most powerful automation builder. Mailchimp was the easiest to send the first campaign. Klaviyo's ecommerce features were the best we tested for Shopify stores.
Our review team includes marketers who have managed email lists from 500 to 500,000 subscribers. Pricing verified from vendor websites in May 2026. All ratings reflect a growing business with 1,000-10,000 subscribers.

⚠️Common Mistakes to Avoid
Choosing Mailchimp just because everyone uses it: It is easy to start but gets expensive fast as your list grows. Brevo gives you more for less
Paying for ActiveCampaign when you only send newsletters: You're paying for automation features you do not use. Start with Brevo or Mailchimp free tiers
Using Klaviyo for a non-ecommerce business: It is built for stores. The features that make it great for Shopify are useless for a SaaS blog
Not warming up a new sending domain: Switching platforms and blasting your entire list will tank deliverability. Warm up gradually over 2-4 weeks
Ignoring SMS as a channel: Brevo includes it free. Customers who get both email and SMS convert at 2-3x the rate of email alone
Choosing based on free tier alone: Price your actual list size. Mailchimp's free tier looks good but the jump to paid is steep

Frequently Asked Questions
Quick answers to common HR software questions
Brevo offers the best free tier with 300 emails/day and unlimited contacts. Mailchimp is easier to start with better templates. For under 2,000 contacts, both free tiers cover everything you'll need.
ActiveCampaign and Brevo consistently achieve the highest inbox placement rates in our tests. But deliverability depends more on your sending practices (authentication, list hygiene, engagement) than the platform. All five platforms support SPF, DKIM, and DMARC.
Yes for beginners and small lists. The free tier (500 contacts) and template library are the best we tested. But Mailchimp gets expensive as your list grows. At 5,000 contacts, Brevo or ActiveCampaign offer better value.
Yes. All platforms support CSV import with subscriber data and custom fields. What does not transfer: email templates, automation workflows, and reporting history. Run both platforms in parallel for 2-4 weeks. There's no perfect migration. Expect some manual work.
ActiveCampaign wins on automation power and built-in CRM. Mailchimp wins on ease of use and templates. If you're sending newsletters, Mailchimp is simpler. If you're building automated sequences with lead scoring, ActiveCampaign is the tool. It is not close. Each platform solves a different problem.
No. Klaviyo is built for ecommerce with Shopify integration, revenue tracking, and abandoned cart flows. For non-ecommerce use, ActiveCampaign or Brevo are better and cheaper. Don't pay for features you'll never use.
Brevo: 300 emails/day free, unlimited contacts, includes SMS. Mailchimp: 500 contacts free, best templates. HubSpot: free CRM includes basic email marketing tools to get started.
Free for under 500-2,000 contacts on most platforms. $15-50/month for 2,000-5,000 contacts with automation. $50-150/month for 5,000-10,000 contacts. Over 10,000 contacts, pricing varies significantly. It is worth getting quotes from 2-3 platforms before committing.
