GoHighLevel

GoHighLevel is an agency-focused platform that combines email marketing, SMS, landing pages, sales pipeline tracking, and CRM in one dashboard. Its pricing is designed for service providers and small businesses, often costing $80-500/month depending on features, and it's scaled to handle high-volume campaigns for multiple clients or properties simultaneously.

Agents often use it as a full operating system for their business, not just email. If you want one platform to run email campaigns, text messages, landing pages, and sales tracking, GoHighLevel is a capable choice; if you only need email marketing, the feature breadth means steeper pricing and learning curve than a focused tool like MailerLite or Flodesk.
