### Before submitting

- [x] I searched existing issues and did not find an equivalent request.

The issue names no files, tests, or entry points, so first inspect the project structure and clarify how events should be shared by email or text. Define the delivery flow and expected behavior before implementing; done means users can send events to friends and family and recipients can view them.
