6 Best Free Email Marketing Tools in 2026 (Actually Free)
Looking for free email marketing tools that don't watermark everything or lock basic features? These 6 platforms offer genuinely useful free plans.
MailerLite
Best Free PlanNot every business can afford to spend $50–$100/month on email marketing software right out of the gate. The good news: several platforms offer genuinely capable free plans that will take you surprisingly far before you need to pay.
The bad news: a lot of "free" email tools are barely usable — they watermark every email, limit you to 100 subscribers, or lock essential features behind paywalls. This guide covers the tools that are actually free in a meaningful way.
✅ Best genuinely free plans
MailerLite has the most complete free plan for small businesses (1,000 subscribers, automation included). ConvertKit has the largest free plan by subscriber count (10,000 subscribers). Beehiiv has the best free plan for newsletter creators (2,500 subscribers with full editor).
What Makes a "Good" Free Plan?
Not all free plans are equal. Here's what we looked for:
- Subscriber limit — how many contacts can you have before paying?
- Email send limit — how many emails can you send per month?
- Feature completeness — are core features (automation, landing pages, analytics) available?
- Branding — does the platform put its logo on your emails?
- Upgrade path — can you stay on the free plan and just pay for subscriber count, or does upgrading force you onto expensive bundles?
The 6 Best Free Email Marketing Tools
| Tool | Best For | Starting Price | Free Plan |
|---|---|---|---|
Top PickMailerLite | Small businesses & beginners | Free up to 1,000 subs | Yes — automation included |
| Creators with large lists | Free up to 10,000 subs | Yes — limited features | |
| Newsletter creators | Free up to 2,500 subs | Yes — full editor | |
| Marketing teams | Free up to 500 contacts | Yes — limited | |
| Brand-familiar users | Free up to 500 subs | Yes — limited |
1. MailerLite — Best Overall Free Plan
MailerLite's free plan is remarkable for what it includes at zero cost:
- Up to 1,000 subscribers
- 12,000 emails per month (12 sends per subscriber/month)
- Drag-and-drop email editor
- Automation workflows (basic)
- Landing page builder (unlimited)
- Website builder
- Pop-up forms and embedded forms
- Basic analytics
The only significant limitations are MailerLite branding in email footers, limited A/B testing, and no priority support. For a small business or creator with under 1,000 subscribers, the free plan provides everything needed to run a professional email marketing operation.
When to upgrade: When you exceed 1,000 subscribers or need unlimited monthly emails, the Growing Business plan starts at $9/month — still one of the cheapest paid options available.
2. ConvertKit — Largest Free Plan by Subscribers
ConvertKit's free plan lets you have up to 10,000 subscribers at zero cost — the most generous free subscriber allowance of any major platform. This makes it attractive for creators who are growing quickly and don't want to pay until they're sure the platform is right.
Free plan includes:
- Up to 10,000 subscribers
- Unlimited landing pages and forms
- Unlimited email broadcasts
- Basic subscriber tagging
Free plan excludes:
- Automation sequences (require Creator plan, $25/month)
- Email sequences
- ConvertKit Commerce
The catch: the features you actually need for sophisticated email marketing (automation, sequences) aren't included. If you're just sending broadcast emails (no automation), the ConvertKit free plan is unbeatable. If you need automation from day one, MailerLite's free plan is more useful.
3. Beehiiv — Best Free Plan for Newsletter Creators
Beehiiv's free plan (up to 2,500 subscribers) is purpose-built for newsletter publishers:
- Full email editor with all templates
- Web presence (yourname.beehiiv.com)
- Basic analytics (opens, clicks, subscriber growth)
- Subscriber management
Beehiiv branding appears on emails and the web presence. You can't use a custom domain, access the ad network, or use the referral program on the free plan.
For a newsletter creator just starting out, Beehiiv's free plan lets you build a professional newsletter up to 2,500 subscribers before spending a dollar.
4. GetResponse — Free for Small Lists
GetResponse's free plan (500 contacts) includes email marketing, one landing page, and basic website creation. It's the most limited free plan on this list by subscriber count, but the quality of the tools (especially the landing page builder) is high.
If you're just starting out and want to test GetResponse's interface before committing, the free plan serves that purpose well. It's not practical for ongoing free use beyond a few hundred subscribers.
5. Mailchimp — Well-Known But Most Restricted Free Plan
Mailchimp offers a free plan for up to 500 contacts and 1,000 emails per month. Given Mailchimp's brand recognition, many beginners start here — but it's actually the most restrictive free plan on this list.
Automation on the free plan is limited to a basic welcome email. No A/B testing, limited templates, and Mailchimp branding on all emails. The 500-contact limit is also the lowest here.
For new users, MailerLite provides strictly more value on its free plan. The only reason to start on Mailchimp free is familiarity with the platform.
6. Brevo (Sendinblue) — Best Free Plan for Email Volume
Brevo (formerly Sendinblue) offers a free plan with up to 300 emails per day (no subscriber limit) — a different model from the rest. This is particularly useful for transactional email use cases or very small businesses with large lists but infrequent sends.
Brevo isn't included in our main comparison table because it's not primarily a newsletter tool, but it deserves mention for its unique free model.
Comparing Free Plans Side by Side
| Platform | Free Subscribers | Monthly Emails | Automation | Branding | |----------|-----------------|----------------|------------|----------| | ConvertKit | 10,000 | Unlimited | No | Yes | | MailerLite | 1,000 | 12,000 | Basic | Yes | | Beehiiv | 2,500 | Unlimited | No | Yes | | GetResponse | 500 | 2,500 | No | Yes | | Mailchimp | 500 | 1,000 | Basic | Yes |
FAQ
Are there truly free email marketing tools with no subscriber limit?
Brevo (Sendinblue) has no subscriber limit on its free plan but limits you to 300 emails per day. ConvertKit allows 10,000 subscribers for free but limits features (no automation). Truly unlimited free plans don't exist in legitimate email marketing — volume always has a cost.
Do free email plans affect deliverability?
Slightly. Platforms with very large free tiers (like Mailchimp) attract more low-quality senders, which can affect shared IP reputation. MailerLite mitigates this by manually approving new accounts. In practice, deliverability differences between free plans are small if your list is clean and engaged.
When should I upgrade from a free plan?
Upgrade when: (1) you exceed the free subscriber limit, (2) you need automation beyond basic welcome emails, (3) you want to remove the platform branding, or (4) you need a custom domain. For most creators, this happens between 500–2,000 subscribers.
Final Verdict
For the best genuinely useful free plan, choose based on your goal:
- Small business with limited budget → MailerLite (most complete free plan)
- Creator expecting fast growth → ConvertKit (largest free list)
- Newsletter publisher → Beehiiv (best newsletter tools for free)
All three let you build a real email presence without spending money until you're ready.
