I tried every FREE email marketing tool. This is the best
1. Groupmail
Groupmail is an email marketing platform designed to help small businesses get started without breaking the bank. Its free plan offers a chance to build email lists and test strategies without spending a cent.
Free Plan Details (Contacts, Sends, Features)
With the free plan, you can manage up to 1,000 contacts and send 2,000 emails per month. While emails include Groupmail branding, you still gain access to essential tools like a drag-and-drop email builder and real-time analytics. These features provide a solid foundation for creating and analyzing email campaigns.
Standout Features (AI, Templates, Integrations, Analytics)
Groupmail packs a punch with its features:
- Groupmail’s AI subject line generator helps you craft eye-catching subject lines in seconds. Trained on high-performing campaigns, it suggests tailored options to boost open rates—no guesswork needed

Thanks to its combination of useful tools and a generous free plan, Groupmail is a great choice for businesses looking to kick off their email marketing efforts effectively.
2. MailerLite
MailerLite has earned a reputation as one of the most generous free email marketing platforms available. It combines AI-driven tools with robust automation features, making it a solid choice for businesses looking to grow their email marketing efforts.
Free Plan Limits (Contacts, Sends, Features)
With MailerLite’s free plan, you can manage up to 1,000 subscribers and send 12,000 emails per month. The plan includes useful tools like a drag-and-drop editor, automation options, pop-ups, surveys, quizzes, and landing pages. However, it does come with some limitations. You’re restricted to one user account, and all campaigns will carry MailerLite branding that cannot be removed. Additionally, the free plan offers fewer email and automation templates compared to its paid plans. On the bright side, new users get access to 24/7 support, which is a rarity for free plans.
MailerLite also incorporates AI tools to enhance email content and optimize delivery timing, further setting it apart from competitors.
AI-Powered Capabilities (Subject Lines, Content, Personalization)
MailerLite’s AI features showcase how free tools can elevate your email marketing. The platform includes an AI subject line generator and a writing assistant that helps craft engaging content. You can even tweak the tone to fit your needs – choose from Natural, Catchy, Professional, or Persuasive styles. Free plan users get credits to try these features before deciding to upgrade. Another standout feature is Smart Sending, which uses AI to identify the best time to send emails to each subscriber, maximizing engagement and personalization.
Automation Tools (Workflows, Triggers, Drip Campaigns)
Automation is another area where MailerLite excels. While full access to advanced features requires a paid plan, the free version still offers plenty of options. You can design automated workflows triggered by specific subscriber actions, like signing up for a group, completing a form, or clicking on a link. These automations make it easier to engage with your audience, nurture leads, and provide tailored experiences in real time.
For example, welcome emails – a common automation – are highly effective. Research shows that 74% of subscribers expect a welcome email, and these emails can generate up to 320% more revenue than standard promotional messages. MailerLite’s tools simplify the process, helping you create workflows that drive better results.
Key Strengths (Templates, Integrations, Analytics)
MailerLite stands out for its high email deliverability rates, earning it a Best of 5 award from Email Tool Tester. Users praise the platform for being affordable, easy to use, and backed by excellent customer support. Its generous email sending limits are another big plus.
The platform integrates seamlessly with e-commerce systems, enabling advanced automations like abandoned cart reminders and personalized post-purchase emails. Real-time analytics let you monitor audience engagement and track growth, while A/B testing features help fine-tune subject lines, email content, and send times for better performance.
When you’re ready to move beyond the free plan, MailerLite offers paid options starting at $9 per month, making it an attractive long-term solution for businesses aiming to scale.
3. Brevo
Brevo stands out with one of the most generous free email marketing plans, blending AI-driven tools with strong automation features. It’s a solid pick for businesses aiming to tap into artificial intelligence while keeping costs low.
Free Plan Limits (Contacts, Sends, Features)
Brevo’s free plan allows up to 100,000 contacts with a daily limit of 300 emails (approximately 9,000 emails per month). However, it restricts users to one account and includes the Brevo logo on emails. Despite these limitations, the plan includes essential features like customizable email templates, a drag-and-drop editor, SMS and WhatsApp campaign options, and transactional email support. For advanced tools like landing pages, Facebook ads, and A/B testing, you’ll need to upgrade to a paid plan.
AI-Powered Capabilities (Subject Lines, Content, Personalization)
Brevo’s AI assistant, Aura, takes email marketing to the next level. Aura helps craft subject lines, generate email content, fine-tune tone to align with your brand, and even add dynamic product recommendations. It also enriches contact profiles by automatically pulling in additional data. Need to refine your message? Aura can rephrase, shorten, or translate your emails into multiple languages.
For example, Feisworld Media, managing a subscriber base of around 2,300, saw their email open rates improve from 17.83% to 25.68% – an increase of nearly 7% over three months – after using Brevo’s AI-powered subject line generator. They also reported saving hours each week on content creation, showcasing how AI can streamline workflows and improve results.
Automation Tools (Workflows, Triggers, Drip Campaigns)
Even with the free plan, Brevo offers marketing automation workflows for up to 2,000 contacts. It includes pre-built templates and an easy-to-use editor, allowing you to set up autoresponders, segmentation, and targeted campaigns based on subscriber behavior. Customizable signup forms are also available to help grow your audience organically.
For businesses looking to expand, paid plans with unlimited automation start at $65 per month. However, the free plan’s automation tools are robust enough for many small to medium-sized businesses, making it a great starting point.
Key Strengths (Templates, Integrations, Analytics)
Brevo excels in personalization, offering features like conditional content, dynamic segmentation, and AI-powered send time optimization to ensure emails are delivered at the perfect moment. A standout feature of the free plan is its multi-channel approach, enabling businesses to run SMS and WhatsApp campaigns alongside email, creating a unified marketing strategy.
The platform also provides detailed analytics and reporting tools to monitor campaign performance and make informed decisions. While customer support on the free plan is somewhat limited, the available resources and documentation are thorough enough to help most users get started.
