Campaign Monitor vs Sendy: What are the differences?

<Write Introduction here>

1. **Pricing Model**: The key difference between Campaign Monitor and Sendy is their pricing models. Campaign Monitor operates on a per-subscriber pricing model, which means the cost increases as the number of subscribers grows. On the other hand, Sendy offers a one-time payment option, allowing users to pay once and use the software indefinitely.
  
2. **Delivery Speed**: Another significant difference is the delivery speed of emails. Campaign Monitor processes and delivers emails through their own servers, which can sometimes result in delays. In contrast, Sendy uses Amazon SES (Simple Email Service) to send emails, ensuring faster and more reliable delivery to recipients. 

3. **Customization Options**: Campaign Monitor provides users with a range of beautiful and professionally-designed templates for email campaigns. Sendy, however, offers more customization options as users can create their templates with HTML and CSS, allowing for more personalized and unique designs.

4. **List Management Features**: Campaign Monitor includes advanced list segmentation and tagging features, making it easier for users to target specific groups within their subscriber lists. On the other hand, Sendy has basic list management capabilities, which may be limiting for users who require more advanced segmentation options.

5. **Reporting Tools**: Campaign Monitor offers detailed analytics and reporting tools that provide insights into open rates, click-through rates, and subscriber engagement. Sendy, while it does provide basic reporting metrics, lacks the robust analytics features found in Campaign Monitor.

6. **User Interface**: Campaign Monitor boasts a user-friendly and intuitive interface that makes it easy for users to create and manage email campaigns. Sendy, on the other hand, has a simpler interface that may require some technical knowledge to navigate effectively.

In Summary, Campaign Monitor and Sendy differ in their pricing models, delivery speed, customization options, list management features, reporting tools, and user interfaces.
