Receiving unsolicited event confirmation emails can stem from various sources. Event organizers may upload lists without consent, purchase lists, or harvest emails from websites. Sometimes, individuals are signed up by mistake, or a friend might have used your email. Data breaches and marketing agreements between websites can also lead to unwanted emails. Poor email list hygiene contributes to the issue, and unsolicited event emails are often considered spam. Legal frameworks like the CAN-SPAM Act require clear opt-out options, and double opt-in methods are crucial for legitimate subscriptions. ISPs struggle to catch low-volume spam, and ESPs may not take action. Reporting spam and managing your subscriptions are essential steps for mitigation.

Additionally, your email address could be on a purchased or shared list. Data breaches and email harvesting techniques also contribute to this issue. Email marketing agreements between websites and lack of explicit consent further exacerbate the problem.
