Online invitations are digital cards or messages sent via email or social media to invite people to events like parties, weddings, or meetings. They often include details such as the date, time, location, and RSVP options. Online invitations can be customized with themes, colors, and images, making them visually appealing and personal. Using online invitations offers several advantages over traditional paper invites. They are eco-friendly, cost-effective, and can be easily shared with a large audience. Additionally, many platforms allow hosts to track RSVPs and send reminders, ensuring better organization for events. Popular services include Evite, Paperless Post, and Canva.
