Best Free Email Marketing Tools

The best email marketing platforms with generous free plans. Start sending professional emails without spending a dime.

What We Looked For

We ranked free plans by their actual usability: subscriber limits, monthly send limits, feature restrictions, and whether essential capabilities like automation and landing pages are included. A free plan that caps at 250 subscribers isn't the same as one that supports 10,000.

How we ranked: Filtered for tools with genuinely useful free tiers, then ranked by overall rating.

Independent ratings. No paid placements. How we score

Frequently Asked Questions

What's the catch with free email marketing plans? +

Free plans typically limit subscriber count (500–10,000), monthly sends, or advanced features like automation and A/B testing. Some add their own branding to your emails. Read the fine print on what's included before committing.

Which free plan has the highest subscriber limit? +

Kit (ConvertKit) offers up to 10,000 subscribers on their free plan, which is the most generous. Mailchimp allows 500 contacts on free, while MailerLite offers 1,000. Limits change frequently, so check the latest on each platform.

Can I run a real business on a free email plan? +

Yes, especially if you're under 1,000 subscribers. Many free plans include the essentials: email broadcasts, basic automation, and sign-up forms. Upgrade to paid when you need features like A/B testing, advanced segmentation, or removing platform branding.
