AI left out Constant Contact — a tool many teams still rate. The brands AI leaves out tend to share one trait: content it can't read. Why AI snubs brands.

How to choose email marketing software

Free tier limitsCheck daily send caps and contact limits. Brevo caps daily sends, while MailerLite and Mailchimp limit contacts. Watch out for restrictive caps that hinder growth.
Automation depthAssess automation features in the free tier. MailerLite includes useful automations, but Mailchimp's free automation has tightened. Brevo's deeper automation requires paid plans.
Ease of useConsider editor simplicity and learning curve. MailerLite has a clean editor, Benchmark Email is simple for beginners. Mailchimp is polished but may overwhelm newcomers.
ScalabilityThink about future upgrades. Free plans limit sending and features. MailerLite and Mailchimp scale to paid plans, but costs can rise quickly.

Frequently asked

Is free email marketing software enough for a real business?

Yes, for early lists, newsletters, and simple automations. You usually outgrow free plans on sending limits, branding, or advanced segmentation.

What matters most in a free plan?

Check contact cap, monthly sends, daily sends, branding, automation access, landing pages, and whether unsubscribed contacts count toward limits.

Which free tool is best for ecommerce?

Brevo and Mailchimp are common picks because of integrations. Your store platform integration quality matters as much as free email limits.

Do free plans usually include automation?

Sometimes, but often only basic automations. More advanced journeys, branching, and behavioral triggers are commonly locked behind paid plans.

Can I switch later without much pain?

Usually yes, but templates, forms, and automations often need rebuilding. Export your list cleanly and keep source tags organized from day one.

How do daily send limits affect my email campaigns?

Brevo's daily send caps can become restrictive. Mailjet offers decent free sending volumes. Consider your campaign frequency before choosing.

Can I use free email marketing for transactional emails?

Brevo is strong for combining marketing and transactional email in one platform. Other tools may require separate services for transactional sending.

What collaboration features are available in free plans?

Mailjet offers real-time collaboration for teams. MailerLite and others also support team accounts, but features may vary.
