# Email & RSVP Messaging System
AddEvent uses a connected system of tools to manage how RSVP events collect responses and send email communications.
This system is made up of four core components:
* **RSVP Forms**: collect attendee information and responses
* **Notification Flows**: automate emails based on event and attendee actions
* **Email Design Templates**: control the look and layout of emails
* **Sender Settings & Domains**: control who emails are sent from and domain authentication
Each component works independently, but they come together when an event is created.
***
## How the system works
When someone registers for an event:
1. The **RSVP form** collects their response and details (you can apply a custom RSVP form to an event).
2. The response triggers a **Notification Flow** (if assigned to the event).
3. Each notification uses an **Email Design template** (if assigned to the notification flow).
4. Emails are sent using a verified **sender domain and sender identity** (if verified in settings and applied to the email design).
***
## Core components
### RSVP Forms
RSVP forms define the questions attendees answer when registering for an event.

Learn more: **Notification Flows**
***
### Email Design Templates
Email Designs control the layout, branding, and structure of emails sent through notification flows and manual attendee emails.

***
### Sender Settings & Domains
Sender settings control the email identity used when sending emails, including:
* Sender name
* Sender email address
