How to Design RSVP Emails with AddEvent’s WYSIWYG Editor how-to

Updated Dec 15th, 2025 by Camella Bridges

When you are hosting an event, every interaction with your attendees matters, especially the emails they receive after RSVPing. Confirmation emails, reminder messages, and follow-ups set expectations and help ensure a smooth experience.

With AddEvent’s WYSIWYG (What You See Is What You Get) email editor, you can design beautiful, on-brand event emails without touching HTML. Whether you are sending automatic RSVP confirmations, automatic RSVP reminder emails, or manually emailing attendees with updates, the editor makes it easy to personalize and professionalize your communications.

This guide walks through how to design RSVP emails using AddEvent’s WYSIWYG editor, beginning with creating your RSVP event, customizing RSVP forms, managing attendees, and building effective email content.

1. Start by Creating an RSVP Event

Before you design email notifications, you need an event with RSVP enabled.

Create an RSVP event

Create an event in your AddEvent dashboard. Toggle RSVP on, which activates attendee tracking and email automation.

Customize your RSVP form

Your confirmation emails can use the data submitted through the RSVP form, so take time to design one that collects the information you need.

Using AddEvent’s customizable form builder, you can:

  • Add new fields
  • Require or hide specific questions
  • Collect preferences
  • Learn more about your attendees ahead of your event

A well-designed form ensures your emails and overall event can be more personal and relevant, for example using the attendee’s name or referencing their selected session.

2. Share Your RSVP Event

Once your event and RSVP form are ready, it is time to promote it.

AddEvent offers several ways to share your online RSVP event, including:

  • A hosted event landing page with sharable URL
  • Embeddable RSVP form widgets
  • Shareable Add to Calendar links for emails
  • Add to Calendar buttons for websites or landing pages

When attendees submit the RSVP form, they can automatically receive your confirmation email, which you can customize using the WYSIWYG editor.

3. Review and Manage Your Attendee Data

Before designing emails, it can also be helpful to review the attendee data you are collecting. This ensures that the fields you want to reference in your emails, such as name, company, or selected time slot, are present and mapped correctly.

In your event dashboard, you can:

  • View attendee submissions
  • Export data
  • Track statuses (confirmed, declined, maybe)
  • Add internal notes

Understanding your attendee information helps you personalize your messaging and streamline follow-ups.

4. Design Your RSVP Emails with AddEvent’s WYSIWYG Editor

Now it is time to design the emails your attendees will receive.

AddEvent’s WYSIWYG email editor allows you to create and edit:

  • Automatic RSVP confirmation emails
  • Automated event reminder emails
  • Manuall emails for event changes or announcements

Key features of the WYSIWYG editor

  • Brand customization
  • Personalization tags
  • Real-time preview and test tools
  • Automatic event details

These details ensure accurate time zones, calendar links, and event updates populate for each attendee.

5. Attendee Email Notifications

AddEvent’s attendee email notifications allow you to automate the messages sent to guests who register for an RSVP event. These automated emails are configured within your custom RSVP Forms and include options for one confirmation email, two reminder emails, and one follow-up email. Each message can be individually enabled, disabled, and customized using the WYSIWYG or code editor.

Setting Up Automated Emails for Your RSVP Event

To configure or customize your automated attendee messages:

  1. From the dashboard, click the RSVP Forms tab.
  2. Select the RSVP form you want to edit, or create a new one. Note: The default Standard RSVP form is read-only and cannot be edited.
  3. Click the Email Notifications tab.

Here you will find all available automated email types associated with the form.

Customization Options for Each Email Type

Each automated email includes its own subject line, schedule, and message content. To customize an email:

  • Click the plus icon on the right side of the email section to open the editor.
  • Edit the subject line using the Email subject field.
  • Customize the content using the visual WYSIWYG editor or switch to the code editor if you prefer working in HTML.
  • To disable an email, toggle the turned on switch for that specific message.

Confirmation Email

The confirmation email is automatically sent when an attendee registers as going or interested. This is often the most important message because it provides immediate acknowledgment and essential event details.

Reminder Emails

You can activate up to two reminder emails for each RSVP form:

  • One reminder scheduled 1 to 7 days before the event.
  • A second reminder scheduled 1 to 23 hours before the event.

Both reminder emails can be fully edited using the WYSIWYG editor. These messages help reinforce attendance and ensure attendees remember the upcoming event.

Follow-up Email

The follow-up email is disabled by default. It allows you to reconnect with your attendees after the event.

  • The included survey link is only a placeholder. You must insert your own feedback form and URL.
  • The follow-up email can be scheduled between 1 hour and 3 days after the event.


Update Email

The update-email is a manual one-off email notification that you can choose to send out to your attendees. Most organizers use the update email to send any date or time changes, or provide additional information as the event gets closer. 

This email template can be customized to match your branding under the RSVP Forms > Email notifications section. To update the content of the email, you can do so in the RSVP event when you go to send the email. 

To send a manual push update email, you will need to do the following:

  1. From the AddEvent dashboard, click into the desired RSVP event
  2. Click See more under the RSVP attendees tile
  1. Click into the second tile titled Email Attendees 
  1. Choose who you would like to send the email to based on RSVP: Going, Interested, or Not Going. 
  2. Update the subject line of the email
  3. Add the information you would like to share with your attendees in the content box
  4. Hit Send

Customizing Email Content

Emails can be formatted using the visual editor or the code editor. You may also insert RSVP form data as tags within the content for more personalized messaging. Once a custom RSVP form is saved, the form and its email notifications can be applied to future events.

By default, automated emails are sent from events@addevent.com, but you can update both the sender name and email address so recipients receive messages from a sender they recognize. If you update the sender email, replies from attendees will be delivered to your chosen inbox.

These automated notifications apply only to the first instance of a recurring event. Reminder and follow-up timing can be adjusted based on your needs.

Best Practices for Effective RSVP Emails

To make the most of AddEvent’s WYSIWYG editor, keep these suggestions in mind.

Keep your message clear and concise

Attendees want quick confirmation and the essential details, such as time, location, and links.

Reinforce next steps

Include calls to action such as:

  • Add to Calendar
  • Join the livestream
  • Update your RSVP
  • View event page

Stay consistent with your branding

Use your brand colors, voice, and style across all event communications.

Personalize when possible

A simple greeting using the attendee’s name helps increase engagement.

Use the Test Email tool before sending

Confirm that images render correctly, buttons work, and spacing looks clean across devices.

Designing clear, professional, on-brand RSVP emails is simple with AddEvent’s tools. The WYSIWYG editor and automated attendee notifications help you create an engaging, seamless experience from the moment a guest submits an RSVP to the final follow-up after your event.
