If you receive an invitation to a wedding, dinner or party then you might be asked to RSVP, or "Répondez s'il vous plait," which means "please reply" in French. The traditional method for responding to an RSVP invitation is to mail a written acceptance, but many invitations now also include an RSVP e-mail address or phone number. For the sake of etiquette and politeness, you should RSVP by e-mail only if the invitation offers this option, or if you received the invitation by e-mail.
Launch your e-mail application and open a new e-mail message.
Type the full RSVP e-mail address, as printed on the invitation, into the message's "To" input field.
Enter the title for your e-mail into the "Subject" input field. Include the name of the event and "RSVP" in the subject line. For example, "RSVP to John and Jane's Wedding."
Type the text of your RSVP into the main body of the email message. Thank the host for the invitation and clearly accept or decline the invitation. Avoid ambiguity or uncertainty -- only send the RSVP when you know whether or not you will attend. Also remember to specify whether you're replying as an individual, or also on behalf of your partner and other family members.
Click "Send" in your e-mail application to send the email RSVP.
Organising an event can be time-consuming and stressful. Help the host by always sending your RSVP by the date specified on the invitation.
