Best for creators
1. ConvertKit (Kit)
8.8/10
ConvertKit is the best email platform we’ve tested for creators, bloggers, and solopreneurs. The visual automation builder is powerful but approachable, the subscriber tagging system is fundamentally better than list-based competitors, and the free plan — up to 10,000 subscribers — is the most generous in the industry. If you’re building an audience and selling your own products or services, ConvertKit is the clear choice.

Best free plan value
2. MailerLite
8.6/10
MailerLite punches well above its price point. The free plan includes automation workflows, landing pages, and pop-up forms — features competitors charge $30+/month for. The interface is clean and modern, and deliverability rates are excellent. Best for small businesses and bloggers who want full functionality without paying for it.

Best automation
3. ActiveCampaign
8.5/10
ActiveCampaign is the most powerful email automation platform available at a small-business price point. If you need complex multi-step sequences, lead scoring, CRM integration, and deep conditional logic, nothing in this list comes close. The tradeoff is a steeper learning curve — it’s not the right tool if you want to set up in an afternoon.

Best for e-commerce
4. Klaviyo
8.3/10
Klaviyo is purpose-built for e-commerce and Shopify stores. Its native integrations with Shopify, WooCommerce, and BigCommerce are best in class, and the revenue attribution reporting tells you exactly how much money each email campaign generated. If you’re running an online store, Klaviyo is the answer — for service businesses, it’s overkill.

Budget pick
5. Brevo (formerly Sendinblue)
8.1/10
Brevo is the best option for businesses with large contact lists on tight budgets. Unlike most platforms that charge by subscriber count, Brevo charges by email volume — so you can have 50,000 contacts and only pay for how many emails you send. The free plan (300 emails/day, unlimited contacts) is unmatched for budget-conscious businesses.
