A. To reduce unsolicited emails, you can set up filters in your email client. For example, in Gmail, go to Settings > Filters and Blocked Addresses > Create a new filter. Enter the email address or keywords associated with the unsolicited emails, then click 'Create filter' and choose 'Delete it' or 'Mark as spam'. This will help keep your inbox clean.

B. Consider using an email service that allows you to create disposable email addresses. Services like ProtonMail or 10 Minute Mail can help you manage unsolicited emails by providing temporary addresses that you can use for sign-ups.
