How do you make sure you get presale tickets?

Could you please elaborate on the process of securing presale tickets? I'm quite interested in understanding the steps involved. Do you have to register or subscribe to a certain service in advance? Are there any specific channels or platforms that offer presale opportunities? Also, how do you ensure that you're notified promptly when the tickets are available? Is there a strategy or tip that you could share to increase the chances of success? I'm keen on learning more about this topic, as it could help me secure tickets for future events.
