Is there any built-in feature with Campaign monitor that provides invitation style functionality? If not I guess i could just add into my design two buttons that say "yes" or "no" and then record who clicks on what... but I am just looking for a quicker solution if possible.
Welcome to the forums, beno-emmw! Yes, you could try that, however I would recommend using a service like Guestlist for collecting RSVPs. Personally, I've used this for events in the past and it works a treat. You can also synchronize registrants with your Campaign Monitor lists and easily send email followups in the lead up to your event.
Let me know if you have any questions and good luck with your event!
Guestlist looks awesome! However there is one major problem... I'm taking it that you can't upload your own creative? That's a huge part of our events. Is it possible to add this functionality?
is there a way to put in some sort of html into the 'edit event information' section?
If you did decide to try using just Campaign Monitor, check out out blog post at http://www.campaignmonitor.com/blog/post/1743/using-campaign-monitor-to-trac/ for some details.
