Direct Answer
For most small service businesses, GoHighLevel (bundled with CRM), MailerLite (free under 1k contacts), or Brevo (free under 300 emails/day) are the best email marketing tools in 2026. Mailchimp's pricing is no longer competitive at small scale; ConvertKit is best for creator-style brands.

Pick the tool that integrates with your CRM. Two disconnected systems is the #1 source of broken automations.
Avoid 'free forever' tools that block automation — automation is where most of the email ROI lives.
