Really expensive and not worth it due to limitations
They may have been the ground breaker in the area of digital invitations but their best days are behind them. We recently used them for two events and frankly the issues were enough for me to explore other services. At least 20% of the invites wind up in Spam and how their web portal is not White listed with all of the email services is beyond me. Then 25% of the RSVPs never posted and at least 10% of the people got their reminders for the event(s) the night of the event (in a few cases after the event happened).
