Best Email Marketing Software: Mailchimp vs. Klaviyo vs. ActiveCampaign

Mailchimp is the default for simple newsletters. Klaviyo is built for ecommerce. ActiveCampaign is the automation-heavy choice. Here's how to pick.

Mailchimp, Klaviyo, and ActiveCampaign pricing varies by team size — choose based on headcount, not features

~$65/moMailchimp

~$140-1,400/moKlaviyo

~$150-300/moActiveCampaign

All three tools serve the same category. The wrong pick means paying for complexity you don't use — or outgrowing simplicity too fast.

Monthly cost comparison

Mailchimp is in virtually every curated vertical at roughly $65/mo for the Standard plan. It's the right choice when your needs are straightforward: newsletters, announcement emails, and basic list segmentation. The interface is genuinely easy, the template library is large, and the pricing is predictable. Where Mailchimp falls short is ecommerce-specific automation (abandoned cart flows, product recommendations) and advanced behavioral triggers. If you're not selling online, you probably don't need those features anyway.

Klaviyo: ~$140-1,400/mo — the ecommerce-native choice

Klaviyo is built around Shopify and ecommerce data. At $140/mo for a smaller list and scaling to $1,400+/mo for larger lists, it's significantly more expensive than Mailchimp — but it does things Mailchimp can't: automated abandoned-cart flows, browse-based product recommendations, and revenue attribution per email. We see Klaviyo primarily in ecommerce verticals where email directly drives revenue. If you're not ecommerce, Klaviyo's premium is hard to justify.

Klaviyo's price scales with list size, not seats — a growing list quietly moves you up a tier.

Klaviyo bills on contact count, not usage — a business that never prunes unengaged subscribers can end up paying $1,400/mo to email a list that's 40% dead addresses. Cleaning your list before renewal is the highest-ROI five minutes in this pillar.

ActiveCampaign: ~$150-300/mo — the automation-heavy option

ActiveCampaign is the most powerful of the three for complex automation: multi-step workflows, conditional branching, lead scoring, and CRM integration. At $150-300/mo for small-business tiers, it's priced between Mailchimp and Klaviyo. The trade-off is complexity — the automation builder has a real learning curve, and most small businesses use only a fraction of its capability. ActiveCampaign is the right choice when your sales cycle is long, your segments are complex, and you have someone who can dedicate time to building automations.

All three tools solve the same underlying job — reaching the right contact at the right moment. Buying the most powerful one and never building the automations it's priced for is the same as buying Mailchimp and pretending it's ActiveCampaign.

The actual decision rule

Questions to ask before choosing an email platform

Are our sends mostly simple newsletters and announcements? Mailchimp wins on simplicity and cost for that job alone.
Do we sell online and need email tied directly to revenue — abandoned cart, browse-based recommendations? Klaviyo is purpose-built for that attribution.
Is our sales cycle long with complex segmentation and multi-step nurture? ActiveCampaign's automation depth is worth the learning curve then.
Do we already have HubSpot or Salesforce for CRM? Check their built-in email tools before paying for a fourth platform.
