Quick answer
EmailOctopus - EmailOctopus wins for most builders who want a bigger, simpler free email plan, while Mailchimp wins if you need broader marketing features and are willing to work within a much tighter cap.
How the free tiers compare
These free tiers solve different problems. EmailOctopus is the more generous starter if your main job is sending email newsletters or basic campaigns at modest scale: 2,500 subscribers, 10,000 emails a month, one landing page, one form, and no card required. Mailchimp’s free plan is narrower on volume, capped at 250 contacts and 500 emails a month, but it offers a much wider product surface area, including audience tools, basic automation preview, surveys, social posting, and a website builder. The tradeoff is that Mailchimp pushes you into paid plans faster, and its pricing steps up by contact count, while EmailOctopus has a simpler jump to a low-cost flat Pro plan. If you are trying to stay free as long as possible, EmailOctopus is the easier fit. If you need more marketing utilities before you pay, Mailchimp is broader but tighter.

After you outgrow the free tier
EmailOctopus has a simple flat upgrade path: Pro starts at $9/month billed yearly, with 10,000 subscribers and 10,000 emails per month in the provided data. Mailchimp also starts flat at $17/month for Essentials, then moves to $25/month Standard and $500/month Premium, but the real pricing driver is contact count and plan tier. For small teams, EmailOctopus is cheaper. Mailchimp becomes materially more expensive as you grow, especially once you need more contacts, more automation, or higher support tiers.
