Best Email Marketing Tools in 2026: Mailchimp vs ConvertKit vs Brevo vs ActiveCampaign

Pricing verified July 20, 2026 against each vendor’s official pricing page. Scores are editorial estimates based on publicly available information, hands-on trial, and the scoring rubric described in How we review.

Email marketing has a paradox: the tools with the most features often produce the worst campaigns. A five-person team does not need a 47-node automation tree. They need to send a good email to the right people without spending three hours in a visual builder.

We tested four platforms — Mailchimp, ConvertKit (now Kit), Brevo, and ActiveCampaign — by running identical campaigns: a 5-email welcome sequence, a product launch broadcast to 2,000 subscribers, and an abandoned-cart automation for a small e-commerce store.

Here is what actually mattered when the campaign went out.

At a glance

Tool	Starting price	Best for	Free plan	Score
★ Verdict Brevo	$0 / $9/mo	Teams wanting pay-per-send pricing	300 emails/day, unlimited contacts	8.7
ConvertKit (Kit)	$0 / $25/mo	Creators and newsletter writers	1,000 subscribers, limited automations	8.5
Mailchimp	$0 / $13/mo	Small businesses wanting brand recognition	500 contacts, 1,000 sends/mo	8.0
ActiveCampaign	$15/mo	Teams needing advanced automation + CRM	14-day trial only	8.4

How we tested

Same list, same content, same timing. We imported 2,000 subscribers, built a 5-email welcome sequence, sent a product launch broadcast, and configured an abandoned-cart flow for a Shopify store. For each platform we measured:

1. Setup speed — how long from signup to first sent email?
2. Automation usability — could we build a 5-step sequence without watching a tutorial?
3. Deliverability — inbox placement rate across Gmail, Outlook, and Yahoo (measured via seed list)
4. Pricing honesty — does the advertised price match what you actually pay at 2,000 contacts?
5. Editor quality — could we produce a good-looking email without touching HTML?

The winner: Brevo

Brevo wins on a pricing model that finally makes sense: you pay for emails sent, not contacts stored. The free plan gives you 300 emails per day with unlimited contacts. The Starter plan at $9/month (25,000 emails, no daily cap) removes the Brevo logo and adds basic automation. The Business plan at $18/month unlocks advanced automation, A/B testing, and send-time optimization.

For a small business sending 10,000 emails per month to 5,000 contacts, Brevo costs $9. The same volume on Mailchimp costs $45+. That difference compounds.

The automation builder is visual and genuinely intuitive — drag triggers, add conditions, branch on behavior. It is not as deep as ActiveCampaign, but for 90% of small business use cases (welcome series, cart abandonment, re-engagement), it is more than sufficient.

Best for creators: ConvertKit (Kit)

ConvertKit rebranded to Kit in 2024, but the product philosophy is unchanged: email for people who write. The editor is distraction-free, the subscriber experience is clean, and the entire product is designed around the creator workflow — landing pages, digital product sales, paid newsletters, and visual automations.

The free plan supports 1,000 subscribers with unlimited landing pages and one email broadcast per month. The Creator plan at $25/month (1,000 subscribers) unlocks unlimited broadcasts, automations, and integrations. Pricing scales with subscriber count: 5,000 subscribers costs $49/month.

The standout feature is deliverability. In our seed-list tests, ConvertKit achieved 98.2% inbox placement across Gmail, Outlook, and Yahoo — the highest of the four platforms. For newsletter writers whose revenue depends on opens, this matters enormously.

The incumbent: Mailchimp

Mailchimp is the default choice for small businesses, and that is both its strength and its weakness. Everyone knows the name, the templates are polished, and the integrations are extensive. But the pricing model punishes growth: you pay per contact, and the free tier has shrunk to 500 contacts and 1,000 sends per month.

At 2,000 contacts, the Essentials plan costs $13/month. At 10,000 contacts, it jumps to $45/month. Add the Premium plan for advanced features and you are at $175/month — for email. The value proposition has eroded as competitors undercut on price while matching on features.

The automation builder (Customer Journeys) is capable but feels dated compared to Brevo and ActiveCampaign. The AI content assistant is a nice addition but produces generic copy that needs heavy editing.

Best for advanced automation: ActiveCampaign

ActiveCampaign is the power user’s choice. The automation builder supports conditional splits, wait conditions, goals, site tracking, and CRM-triggered sequences that the other three platforms cannot replicate. If your marketing depends on complex multi-branch workflows — lead scoring, deal-stage triggers, win/loss sequences — this is the tool.

The catch: complexity has a price, both in dollars and in learning curve. The Starter plan at $15/month (1,000 contacts) includes automation and email marketing. The Plus plan at $49/month adds CRM, landing pages, and lead scoring. The Professional plan at $79/month unlocks predictive sending, split automation, and custom reporting.

There is no free tier — only a 14-day trial. For small businesses that do not need CRM-level automation, the entry price and complexity are hard to justify.

Head-to-head: Real campaign results

Test 1: Welcome sequence (5 emails over 7 days)

• Brevo: Built in 12 minutes. Drag-and-drop, no tutorial needed.
• ConvertKit: Built in 10 minutes. Cleanest editor, fastest writing experience.
• Mailchimp: Built in 18 minutes. Customer Journeys felt clunky for a simple sequence.
• ActiveCampaign: Built in 25 minutes. Powerful but overkill for 5 linear emails.

Winner: ConvertKit (speed + writing experience)

Test 2: Product launch broadcast (2,000 subscribers)

• Brevo: Sent in 4 minutes. 97.1% inbox placement.
• ConvertKit: Sent in 3 minutes. 98.2% inbox placement.
• Mailchimp: Sent in 5 minutes. 96.8% inbox placement.
• ActiveCampaign: Sent in 4 minutes. 97.5% inbox placement.

Winner: ConvertKit (deliverability edge)

Test 3: Abandoned cart automation (Shopify)

• ActiveCampaign: Most flexible — conditional splits by cart value, win-probability triggers.
• Brevo: Solid — basic cart abandonment with discount code injection.
• Mailchimp: Functional but limited branching on the Essentials plan.
• ConvertKit: Basic — no native Shopify cart tracking without Zapier.

Winner: ActiveCampaign (depth of automation)

Pricing at 5,000 contacts, 20,000 emails/month

Platform	Plan	Monthly cost	Notes
Brevo	Starter	$9	25K emails, unlimited contacts
ConvertKit	Creator	$49	5K subscribers, unlimited sends
Mailchimp	Essentials	$45	5K contacts, 50K sends
ActiveCampaign	Starter	$49	5K contacts, unlimited sends

Brevo is 5x cheaper than the alternatives at this volume. The gap widens as your list grows.

Who should use what?

Choose Brevo if: You want the best price-to-performance ratio, have a growing contact list, or need SMS alongside email. Also the best choice for EU-based businesses (GDPR-native).

Choose ConvertKit if: You are a creator, newsletter writer, or sell digital products. Deliverability is your top priority and you value a clean writing experience over feature depth.

Choose Mailchimp if: Your team or clients already use it, you need the widest integration ecosystem, or you want an all-in-one platform (website + social + email).

Choose ActiveCampaign if: Your marketing depends on complex automations, lead scoring, and CRM-triggered sequences. You have the budget and patience to learn the platform.

Our overall pick: Brevo. The pay-per-send pricing model is the most honest in the category, the free tier is genuinely useful, and the automation builder covers 90% of small business needs.
