Brevo - Best Overall for SMBs** Brevo (formerly Sendinblue) has evolved from a simple email tool into a comprehensive marketing platform, and its AI features make it a powerhouse for small and medium-sized businesses. Its AI assistant helps you generate entire email campaigns, from subject lines to body copy, based on a simple prompt. But its standout feature is the Send Time Optimization (STO).

The Content Optimizer analyzes your email copy against best practices from billions of emails, giving you suggestions to improve readability and tone.
