Mailchimp vs ActiveCampaign vs Klaviyo (2026)
One correction most guides get wrong: Mailchimp’s free plan is 250 contacts and 500 sends/month — not 500 contacts as widely shown. ActiveCampaign Starter $15/mo confirmed. Klaviyo free plan also 250 profiles / 500 sends.
Mailchimp free plan = 250 contacts, 500 sends/month — not 500 contacts / 1,000 sends as most guides still show. If you exceed 250 contacts, email sending is paused until you upgrade. Klaviyo free plan: 250 profiles, 500 sends (matches Mailchimp’s limits). All prices verified May 2026.

- ActiveCampaign — Best for complex automation and B2B lead nurturing. Starter $15/mo (1,000 contacts). 14-day trial. 900+ automation recipes. Most powerful workflows in comparison.
- Klaviyo — Best for ecommerce (Shopify, WooCommerce). Free: 250 profiles / 500 sends. Email from $45/mo (1K contacts). Deepest revenue attribution. Email + SMS native.

Verified Pricing (May 2026)
Key correction: Mailchimp’s free plan is 250 contacts and 500 sends/month — not 500 contacts / 1,000 sends as most comparison guides still show. If you exceed 250 contacts on free, Mailchimp pauses your email sending until you upgrade or reduce your list. Both Mailchimp and Klaviyo have identical free plan limits at 250 contacts / 500 sends. ActiveCampaign has no free plan but Starter at $15/mo for 1,000 contacts is the cheapest paid option with full automation included.

The Full Picture
Mailchimp — Best Starting Point, With a Corrected Free Plan
Mailchimp remains the default choice for email marketing beginners. The drag-and-drop email builder is the most intuitive in the category, the template library is the largest, and the platform is genuinely approachable for someone building their first email campaign. The included landing page and website builder reduce the need for additional tools at the early stage.
One correction matters for anyone evaluating the free plan: Mailchimp free supports 250 contacts and 500 sends per month — not 500 contacts / 1,000 sends as the majority of comparison guides still show. The daily send limit on free is also 250. If your contact list exceeds 250, Mailchimp places a hold on email sending until you upgrade to a paid plan or remove contacts. This is a meaningfully lower ceiling than most guides suggest, and it affects the cost calculation for anyone planning to start free and stay there.
The automation ceiling is the main reason teams outgrow Mailchimp. The Essentials plan ($13/month base) has limited automation compared to ActiveCampaign. Full automation workflows require the Standard plan ($20/month base). At higher contact tiers, Mailchimp Premium becomes significantly more expensive than ActiveCampaign Pro for equivalent contact counts. For teams with 10,000+ contacts and complex automation needs, the cost difference is substantial enough to justify a platform switch.
ActiveCampaign — Most Powerful Automation, Best Value at Scale
ActiveCampaign’s Starter plan at $15/month for 1,000 contacts delivers more automation capability than Mailchimp Standard at a similar or lower price. The 900+ pre-built automation recipes, conditional branching, and multi-step workflows are available from the entry plan — not locked behind premium tiers. For B2B companies with complex lead nurture sequences, event-triggered workflows, and multi-touchpoint campaigns, ActiveCampaign is the most capable platform in this comparison.
The value proposition strengthens as contact lists grow. At 25,000 contacts, ActiveCampaign Pro runs approximately $149/month — roughly $120/month cheaper than Mailchimp Premium ($270/month) while offering more automation power. The CRM pipeline, available as an add-on on Plus and higher plans, makes it possible to manage sales and marketing workflows in a single platform without adding a separate CRM like Pipedrive. Free migration support on Pro and Enterprise plans reduces the friction of switching from Mailchimp or another platform.
ActiveCampaign’s limitations are worth noting. There is no permanent free plan — the 14-day trial gives full feature access but requires a credit card or commitment after that. SMS marketing is an add-on not available on Starter, which matters for multi-channel campaigns. The automation builder is powerful but has a steeper learning curve than Mailchimp’s simpler interface — plan for setup time when migrating from a simpler platform.
Klaviyo — The Ecommerce Email Standard
Klaviyo is purpose-built for ecommerce. Its deep Shopify integration syncs customer purchase data, browsing behaviour, and lifetime value in real-time, enabling segments and automations that other platforms cannot match. A segment like “customers who purchased Product A in the last 60 days, ordered more than 2 times, with predicted LTV above $200” can be created and acted on within minutes. The pre-built ecommerce flows — abandoned cart, browse abandonment, post-purchase, win-back, price-drop alerts — are proven revenue drivers that make the platform the standard for DTC and Shopify-based brands.
The revenue attribution reporting is the strongest argument for Klaviyo’s premium pricing. You can see exactly which emails drove which purchases, attributed revenue per flow, and return-on-investment per campaign in a way that neither Mailchimp nor ActiveCampaign can match for ecommerce contexts. For stores where this attribution data informs real decisions about which campaigns to prioritise and scale, the additional cost vs Mailchimp or ActiveCampaign is justified by clearer ROI visibility.
Klaviyo’s free plan has identical limits to Mailchimp free: 250 profiles and 500 sends per month. The paid tiers are the most expensive in this comparison — Email from $45/month for 1,000 contacts, compared to $15/month for ActiveCampaign Starter. For non-ecommerce businesses, the ecommerce-specific features are irrelevant and the premium is unjustified. Klaviyo is the right choice when you sell products online and revenue attribution matters; Mailchimp or ActiveCampaign are better fits for everything else.

Best Tool by Use Case
Hidden Costs & Gotchas
Mailchimp — Free plan is 250 contacts, not 500
Most comparison guides and review articles still show Mailchimp free as 500 contacts / 1,000 sends. The actual current limits are 250 contacts and 500 sends per month, with a daily limit of 250. If you exceed 250 contacts, email sending is paused until you upgrade or reduce your list.
Mailchimp — Automation requires Standard plan
The Essentials plan ($13/month) has limited automation. Full multi-step workflows require the Standard plan ($20/month base). Teams evaluating Mailchimp for automation should budget for Standard from the start, not Essentials.
ActiveCampaign — No free plan, ever
ActiveCampaign has no permanent free tier. The 14-day trial gives full feature access but requires upgrading after. For teams that need a permanent free option, Mailchimp or Klaviyo are the only choices in this comparison.
ActiveCampaign — SMS is an add-on
SMS marketing is not available on the Starter plan and requires a paid add-on on Plus and higher plans. Teams needing integrated email + SMS should evaluate Klaviyo’s native SMS capability, which is more cost-effective than ActiveCampaign’s add-on model for high-volume SMS senders.
Klaviyo — Email and SMS billed separately
Klaviyo’s email and SMS plans have separate pricing. Adding SMS creates a second billing line. The combined Email + SMS plan at $60/month for 1,000 contacts is more expensive than starting with Email only at $45/month. Budget for both if SMS is part of your strategy from day one.
All three — Contact counts include unsubscribers
All three platforms count unsubscribed and inactive contacts toward your contact limit unless you actively suppress or archive them. Cleaning your list regularly (archiving bounced and unsubscribed contacts) prevents you from paying for contacts you can’t email. List hygiene is a cost-saving practice on all three platforms.
