I was asked this question earlier in the week, and thought it would be interesting to ask the group.
How far in advance do you start to sell (and really push) ticket sales? For context, it would super helpful if you could reference what kind of event you run (e.g. a conference, a festival, a music gig, a yoga class etc.), how frequently you run them and average ticket prices. That should give some good context around how far out you should start the promotion.
