Compare ten real email marketing tools. Answer five questions. We check published free-plan capacity, then explain what you still need to verify. This is a planning aid, not a product test or a guarantee.
Explore the selection Newsletters and creators: MailerLite, Kit, EmailOctopus and Sender. Ecommerce: Omnisend and Klaviyo. Broader marketing: Mailchimp, Brevo, GetResponse and Moosend. These are editorial browsing groups, not exclusive product capabilities or rankings.
Sender: 2,500 subscribers and 15,000 monthly emails. Omnisend: 250 unique contacts reached and 500 monthly emails. Klaviyo: 250 active profiles and 500 monthly emails. Moosend offers a 30-day trial rather than a lasting free plan.

How the result is calculated Monthly workload = subscribers x newsletters + additional emails. All ten tools are assessed using the same rules. Capacity does not establish integration support, usability or inbox placement. Budget preference never changes a capacity result; paid tiers require a current quote. Your inputs stay in this browser tab and are not stored or sent to us.
