1. MailerLite — Best Free Plan Overall

MailerLite offers the best balance of features on its free plan. You get 1,000 subscribers, 12,000 monthly emails, a drag-and-drop editor, 10 landing pages, and basic automation — all for free.

What you get free:

• 1,000 subscribers
• 12,000 emails/month
• Drag-and-drop editor
• Basic automation
• 10 landing pages
• Signup forms and pop-ups
• 24/7 email support

What’s locked to paid: Advanced automation, auto-resend, A/B testing, custom HTML editor.

Why it wins: Most platforms limit automation to paid plans. MailerLite gives you basic automation for free, which is enough for welcome sequences and simple workflows.

2. Kit (ConvertKit) — Best Free Plan for Creators

Kit’s free plan covers 1,000 subscribers with unlimited emails, landing pages, and forms. The big limitation: automation and sequences are paid-only.

What you get free:

• 1,000 subscribers
• Unlimited emails
• Unlimited landing pages and forms
• Tag-based subscriber management
• Creator Network access
• Community support

What’s locked to paid: Automation, email sequences, third-party integrations, live chat support.

Why it’s great: If you’re a creator building an audience and just need to collect subscribers and send broadcasts, Kit’s free plan is perfect. You can upgrade to automation when you’re ready.

3. Brevo — Best for Unlimited Contacts

Brevo (formerly Sendinblue) takes a unique approach: unlimited contacts, but limited daily sends. This is ideal if you have a large list but don’t email frequently.

What you get free:

• Unlimited contacts
• 300 emails/day (~9,000/month)
• Email editor
• Marketing automation
• SMS marketing
• Chat widget

What’s locked to paid: No Brevo branding removal, no A/B testing, limited daily sends.

Why it’s great: Unlimited contacts is rare on a free plan. If you have a growing list but send infrequently (weekly or biweekly), Brevo is ideal.

4. AWeber — Best Free Templates

AWeber’s free plan gives you access to their 700+ template library, which is the largest in the industry. For businesses that need professional email designs without paying.

What you get free:

• 500 subscribers

• Unlimited emails
• 3 sales funnels
• 1 course / membership site
• Affiliate management
• Blog
• Automation workflows

What’s locked to paid: More funnels, courses, custom domains, and coupon codes.

Why it’s great: If you need more than just email marketing — courses, funnels, or affiliate management — Systeme.io’s free plan is unbeatable.

When to Upgrade

You should consider upgrading from a free plan when:

• You hit the subscriber or email send limit
• You need automation (if not included free)
• You want to remove platform branding
• You need A/B testing for optimization
• Your business is generating revenue from email

For most businesses, the free plan is sufficient for the first 3-6 months. Once you’re consistently growing and earning from your list, the upgrade investment pays for itself.

The Bottom Line

Start with MailerLite if you want the most complete free experience. Choose Kit if you’re a creator. Pick Brevo if you have a large list. Try Systeme.io if you need an all-in-one platform.

All of these free plans are permanent — no credit card required, no trial expiration. For a broader comparison including paid plans, see our best email marketing software roundup or our best email marketing for small business guide. Start today and upgrade when it makes financial sense.
