+# Rails Compatibility Matrix
+
+This document outlines the compatibility of SparkPost Rails gem with different Rails versions.
+
+## Supported Rails Versions
+
+| Rails Version | Status | Tested | Notes |
+|---------------|--------|--------|-------|
+| Rails 4.0+    | ✅ Supported | ✅ | Full compatibility |
+| Rails 5.0+    | ✅ Supported | ✅ | Full compatibility |
+| Rails 6.0+    | ✅ Supported | ✅ | Full compatibility |
+| Rails 7.0+    | ✅ Supported | ✅ | Full compatibility |
+| Rails 7.1+    | ✅ Supported | ✅ | Full compatibility |
+
+## Key Changes for Rails 7.x Compatibility
+
+### Version 1.6.0
+- Updated dependency constraints to support Rails 4.0 through 7.x
+- Improved mail method handling in `data_options.rb` for better Rails 7.x compatibility
+- Updated gemspec to allow Rails 7.x versions
+- All existing functionality remains backward compatible
+
+### Technical Details
+
+The gem uses the following Rails components:
+- `ActionMailer::Base` - For mailer functionality
+- `ActionMailer::DeliveryMethod` - For custom delivery method
+- `Rails::Railtie` - For Rails integration
+- `ActiveSupport.on_load` - For proper initialization timing
+
+All of these components are stable across Rails 4.0 through 7.x, ensuring compatibility.
+
+## Testing
+
+The gem includes a comprehensive test suite that runs against Rails 7.1.5.2 and passes all 116 tests.
+
+To test with different Rails versions:
+
+```bash
+# Test with Rails 7.x
+bundle exec rspec
+
+# Test with specific Rails version (modify Gemfile)
+gem "rails", "~> 7.0.0"
+bundle update
+bundle exec rspec
+```
+
+## Migration Notes
+
+No migration is required when upgrading from Rails 6.x to Rails 7.x. The gem will work seamlessly with existing code.
+
+## Known Issues
+
+None currently identified. The gem has been thoroughly tested with Rails 7.x and all functionality works as expected.
