Hi, I am sending an email invitation for an event to my contacts. Within the email, I want recipients to have the option to RSVP with a "yes i can attend" button or "no sorry i can't". If i create CTA buttons - how will i record who has RSVP'd from these buttons? Is it Smart Lists? I want it to be a quick and easy for the recipients to RSVP i.e i don't want them to have to click through to a landing page and fill out their details, because i already have them. Please let me know the best way to set this up. Thank you Allison
